Title:

Vegetation Spatial Database Coverage for the Acadia National Park Vegetation Mapping Project

Abstract:

The U.S. Geological Survey (USGS) Upper Midwest Environmental Sciences Center (UMESC) has produced the Vegetation Spatial Database Coverage (vegetation map) for the Acadia National Park Vegetation Mapping Project, USGS-NPS Vegetation Mapping Program (VMP). The vegetation map is of Acadia National Park (NP) and extended environs, providing 99,693 hectares (246,347 acres) of map data. Of this coverage, 52,872 hectares (130,650 acres) is non-vegetated ocean, bay, and estuary (53% of coverage). Acadia NP comprises 19,276 hectares (47,633 acres) of the total data coverage area (19%, 40% not counting ocean and estuary data). Over 7,120 polygons make up the coverage, each with map class description and, for vegetation classes, physiognomic feature information. The spatial database provides crosswalk information to all National Vegetation Classification System (NVCS) floristic and physiognomic levels, and to other established classification systems (NatureServe’s U.S. Terrestrial Ecological System Classification, Maine Natural Community Classification, and the USGS Land Use and Land Cover Classification). This mapping project has identified 53 NVCS associations (vegetation communities) at Acadia National Park through analyses of vegetation sample data. These associations are represented in the map coverage with 33 map classes. With all vegetation types, land use classes, and park specific categories combined, 57 map classes define the ground features within the project area (58 classes including the class for no map data). Each polygon within the spatial database map is identified with one of these map classes. In addition, physiognomic modifiers are added to map classes representing vegetation to describe the vegetation structure within a polygon (density, pattern, and height). The spatial database was produced from the interpretation of spring 1997 1:15,840-scale color infrared aerial photographs. The standard minimum mapping unit (MMU) applied is 0.5 hectares (1.25 acres). The interpreted data were transferred and automated using base maps produced from USGS digital orthophoto quadrangles. The finished spatial database is a single seamless coverage, projected in Universal Transverse Mercator, Zone 19, with datum in North American Datum of 1983. The estimated overall thematic accuracy for vegetation map classes is 80%.

Supplemental_Information:

Of the 58 map classes used to define polygons of the vegetation map, 33 represent the 53 NVCS natural/semi-natural associations (vegetation communities) identified with this project, as defined by NatureServe. Another 3 map classes represent NVCS natural/semi-natural types at the alliance or formation level, describing beach and tidal zone vegetation. There are 5 map classes categorized as cultural vegetation, representing NVCS vegetation at the formation level, 3 of which fall under the cultivated/planted subgroup. 4 map classes represent variations of small islands with vegetation (project-derived to map those islands that are > 0.1 hectares but less than the MMU). The USGS Land Use and Land Cover Classification (level II) define 7 land use map classes, and 3 non-vegetated bodies of water. Another 2 map classes are project-derived to map 2 other non-vegetated bodies of water that did not fit in the USGS classification. 1 map class describes areas of no map data; areas purposely not mapped yet fall within the overlying exterior project boundary. A detailed listing of all map classes and their link to the various parent classification systems (plus listing of physiognomic modifiers that are added to map classes representing vegetation) is provided in the Entity and Attribute Information section of this metadata report. They are also listed in the Project’s technical report. --- The Vegetation Spatial Database Coverage is available in ArcInfo Export (e00), Spatial Database Transfer Standard, and Shapefile formats on the Project’s CD-ROM.

   Classification_System_Modifications:

   This is the version of The PLANTS Database that is used in the The Nature Conservancy's PLOTS Database System (Version 1.1, 1997).

   Taxonomic_Procedures:

   Vegetation field sampling data were entered into a modified version of The PLOTS Database (The Nature Conservancy 1997) at the Maine Natural Areas Program, which (after checking the data for accuracy) was used to produce plot vegetation summaries and associated environmental information. To analyze vegetation patterns and classify types, we used Detrended Correspondence Analysis (DCA), Two-Way Indicator Species Analysis (TWINSPAN), and Indicator Species Analysis (ISA) within PC-ORD. An ordination technique, DCA arranges samples along derived axes according to compositional similarity. A divisive polythetic technique, TWINSPAN classifies samples and species, using a similar algorithm to that for DCA. The ISA identifies indicator species for user-defined groups of samples (in this case vegetation types) by calculating an indicator value based on a species’ abundance and frequency in each of several defined groups, then using a Monte Carlo test to determine those that are significantly allied with one group as opposed to randomly distributed. Further references for all techniques can be found in the PC-ORD documentation (McCune and Mefford 1999). Whereas vegetation types were being developed and refined from the sample data, reference to the NVCS (Anderson et al. 1998) had to be maintained. The required consultations with TNC regional ecologists to (1) determine if an existing NVCS type fit the Acadia type; (2) if no existing NVCS type matched, whether it made sense to refine an existing type or to create a new type; and (3) if a new type was indicated, to name and describe that type.

   Aerial photographs of Acadia National Park and environs were collected as baseline imagery data to produce the vegetation spatial database coverage for the Acadia National Park Vegetation Mapping Project, USGS-NPS Vegetation Mapping Program. --- Participants of the mapping project’s initial scoping meeting (March 1997) agreed to acquire aerial photography of Acadia National Park and extended environs during spring 1997 so that fieldwork and mapping could get underway during the following summer and fall seasons. Aero-Metric, Inc. of Sheboygan, Wisconsin executed the aerial photography mission via contract with the U.S. Army Corp of Engineers (Project Number 1970520), a joint initiative with the U.S. Geological Survey Upper Midwest Environmental Sciences Center (UMESC) of La Crosse, Wisconsin. --- All park fee and easement lands and extended environs were successfully photographed May 27 and 28, 1997 using color infrared dia-positive transparent film (9 x 9 inch size). The photos were collected with an above ground level of 7,920 feet with a lens focal length of 6 inches, resulting in a photo scale of 1:15,840 (negative scale of 1 inch = 1,320 feet, or 4 inches = 1 mile). A 30% side lap (between each flight line) and 60% forward lap (along each flight line) collection standard insured full coverage and stereo viewing. 1179 photos were collected across 28 initial flight lines covering the entire project area. An additional 37 photos across 4 flight lines were re-flown over the mountainous areas of Mount Desert Island to adjust the photo scale of the high mountain terrain. In all, 1216 photos were collected. Two sets of contact prints were made from the original photo transparency film (one set for the field sampling process, and one set for the mapping process).

2. How were the data generated, processed, and modified?

   Date: 1999 (process 1 of 7)

   INTRODUCTION: --- The Vegetation Spatial Database Coverage (vegetation map) was produced for the Acadia National Park Vegetation Mapping Project, USGS-NPS Vegetation Mapping Program. The focus of this metadata report centers on the vegetation map itself and not necessarily on vegetation classification or accuracy assessment. Although references are made to classification and accuracy assessment, their full documentation is found in separate metadata reports and in the Project’s technical report. Acadia National Park (NP) required a high collaborative process between the mapping team, U.S. Geological Survey (USGS) Upper Midwest Environmental Sciences Center (UMESC), and the ecology team, The Nature Conservancy (TNC), NatureServe, and Maine Natural Areas Program (MNAP). In hopes to expedite the project, it was determined at the Project’s scoping meeting to proceed with the vegetation mapping simultaneous to (and thus, prior to) vegetation classification. Map classification and conventions in regard to natural/semi-natural vegetation types were developed based on concepts of the National Vegetation Classification System (NVCS) coupled with perceptions of the vegetation known at that time. Subsequent to mapping, vegetation analysis and classification development were completed, some with other than anticipated results. The vegetation map, therefore, went through substantial modifications to best accommodate the final version of the vegetation classification. Nevertheless, because of mapping prior to classification, some ambiguity exists between the map and vegetation classifications.

   Date: 1997 (process 2 of 7)

   SCOPING MEETING: --- Participants from the USGS (Center for Biological Informatics and UMESC), National Park Service (Acadia NP, Boston office), TNC (eastern regional office and home office), and MNAP met March 25-26, 1997 at Acadia NP Headquarters, Bar Harbor, Maine to discuss the mapping project. Acadia NP staff became informed of the USGS-NPS Vegetation Mapping Program, and mapping and ecology teams learned about the Park’s management and science issues. A preliminary schedule with assigned tasks was developed and a project boundary was established.

   Date: 1997 (process 3 of 7)

   AERIAL PHOTOGRAPHY: --- Scoping meeting participants agreed to acquire aerial photography during spring 1997 so that fieldwork and mapping could get underway during the following summer and fall seasons. The UMESC collaborated with the U.S. Army Corp of Engineers to contract with Aero-Metric, Inc. (Sheboygan, WI) to fly the photo mission. Color infrared (CIR) photographs were collected May 27-28, 1997 at a scale of 1:15,840. In all, 1216 aerial photographs were successfully collected covering all Park fee and easement lands and extended environs. More details on the Project’s aerial photographs are provided in Source Information just prior to Process Step, both in this Data Quality section (source citation abbreviation ACAD Spring 1997 CIR Aerial Photographs).

   Data sources produced in this process:

   • ACAD Spring 1997 CIR Aerial Photographs

   Date: 1997 (process 4 of 7)

   FIELD RECONNAISSANCE & MAP CLASSIFICATION: --- Prior to photointerpretation, field reconnaissance was performed throughout the 1997 field season by the photointerpretation team to learn, test, and verify photo signatures and to establish a map classification. Ecologists intermittently assisted to assure correct field calls and to verify additional vegetation types as they were encountered. During the following fall and winter, mapping protocols were developed and the aerial photointerpretation team began delineating and classifying polygons. During the 1998 field season, field reconnaissance activities resumed, with additional map validation and revisions to the map classification and conventions. --- Throughout the mapping project, the map classification had undergone several updates and adjustments, reflecting knowledge of the vegetation and landscape at those given times. For a listing of map classes, see the Entity and Attribute Information section of this metadata report. A breakdown of map classes into general categories is provided at the beginning of this metadata report under the Supplemental Information of the Identification Information section.

   Data sources used in this process:

   • ACAD Spring 1997 CIR Aerial Photographs
   • U.S. National Vegetation Classification (TNC 1998)

   Date: 1998 (process 5 of 7)

   PHOTOINTERPRETATION: --- Photointerpretation was performed using the spring 1997 CIR film transparencies. The photographs were cut from rolls and covered with clear acetate overlays. The overlays were registered to the photos. Ground features were interpreted and delineated onto the photo overlays using Bausch and Lomb Zoom 240 stereoscopes over Richards MIM2 light table. Each photograph was viewed with its matching stereo pairs so images could be seen in 3-dimensions. To minimize edge distortion, interpretation was focused towards the center of each photograph. Polygons were delineated defining ground features and attribute codes were scribed onto the overlays using Rapidograph ink pens. --- Texture, height, pattern, life form, and position in the landscape were all used in the decision process of delineating polygons and assigning map class codes. When applicable, physiognomic modifier codes were added in conjunction with the map class codes. Larger polygons were delineated first, with subsequent smaller polygons delineated down to the minimum mapping unit of 0.5 hectares (1.25 acres). Small islands with vegetation were mapped to 0.1 hectares (0.25 acres). A total of 236 photos were interpreted with classified polygon data for subsequent digital automation to produce the spatial database coverage.

   Data sources used in this process:

   • ACAD Spring 1997 CIR Aerial Photographs
   • ACAD Map Classification (UMESC 2003)

   Date: 1998 (process 6 of 7)

   MAP AUTOMATION & DRAFT SPATIAL DATABASE: --- Bausch and Lomb zoom transfer scopes were used to transfer photointerpreted data to geo-referenced base maps. The transfer process removed much of the aerial photograph's inherent distortion and tied the interpreted data to real-world coordinates so it could be digitally automated. A total of 65 USGS 3.75-minute DOQ were used to plot hard copy (film acetate) orthophoto base maps at a scale of 1:12,000. The polygons were manually transferred to overlays that were registered to the base maps. Polygon attribute codes were added to a second overlay that was positioned and referenced over the polygon overlay. The overlays were subsequently rechecked for accuracy. --- Each overlay of transferred data was scanned using a large format sheet scanner at a resolution of 400 dots per inch. The resulting Tagged Image File Format images were then converted to a grid using ArcInfo (Version 7.2.1 Patch 2). The converted grid was projected to Universal Transverse Mercator (UTM), Zone 19, with datum in North American Datum of 1983 (NAD83). Each individual grid was transformed to geo-referenced boundary coverages (from the DOQ) to digitally reference the data to real-world coordinates. In ArcTools, the ArcScan utility was used to trace the referenced polygon data producing an ArcInfo coverage. Each intermediate coverage was edited for errors, assigned attributes to polygons, checked against the hand-transferred overlays for line and attribute errors, and finally joined together to produce a seamless spatial database coverage of the vegetation map. --- This draft version (BETA) of the spatial database was distributed to the VMP and Acadia NP for initial review and use. Because community vegetation classification had not sufficiently been developed at the time of release, the BETA version was supported only with map classification information (map classes and physiognomic vegetation data).

   Data sources used in this process:

   • ACAD Spring 1997 CIR Aerial Photographs
   • ACAD USGS 3.75-minute DOQ (USGS 1991)

   Data sources produced in this process:

   • ACAD BETA Vegetation Map (UMESC 2000)

   Date: 2003 (process 7 of 7)

   FINAL SPATIAL COVERAGE: --- The map coverage went through a series of edits once the vegetation analyses and community descriptions were finished. Some vegetation concepts that were understood in theory during the photointerpretation stage had been revised from the results of the vegetation analyses. This became evident once the accuracy assessment was initially applied to the map (with an overall accuracy below 80% standard). Numerous global consolidations (that is, universal classification changes of all like-classified polygons) were applied to the map to best align the map classification to the final vegetation classification. Reaching the accuracy standard, the vegetation map was made final, complete with a direct link to the vegetation classification within the database. --- The map coverage attribute table contains numerous items that provide a set of information for each polygon. The attribute table was originally produced in spreadsheet format (dBASE IV), and then converted to an ArcInfo table using ArcInfo (Version 8.0.2). The table was merged with the spatial coverage using MAP_ATT as the common attribute item. For the list of attribute items, refer to the Entity and Attribute Information's Entity and Attribute Overview section within this metadata report. The final Vegetation Spatial Database Coverage made into an ArcInfo Export (.e00) file. (Note: Spatial Database Transfer Standard and Shapefile formats are produced from the ArcInfo coverage.)

   The Acadia National Park Vegetation Mapping Project is a product of the USGS-NPS Vegetation Mapping Program (VMP), which is managed by the U.S. Geological Survey (USGS) Center for Biological Informatics (for more information on VMP, see larger work citation below). The mapping project is one of few listed as pilot, with purpose to test and explore protocols in mapping and classifying vegetation for the VMP. --- The project began with a planning meeting March 1997 at Acadia National Park (NP). Spring photography was collected May 1997, the baseline data for subsequent field efforts and mapping. Vegetation samples were collected over 3 field seasons (1997-1999), with the majority collected during the first 2 years. Photointerpretation and subsequent digital automation transpired during 1998 & 1999, with supporting fieldwork during the 1997 & 1998 field seasons. The first draft of the vegetation map was completed and distributed January 2000. Vegetation data analyses for vegetation classification development were performed during 1999 & 2000. Local vegetation community descriptions were completed 2001. Accuracy assessment field data was collected during the 1999 field season. The data was applied to the vegetation map with concluding results spring 2003. --- The USGS Upper Midwest Environmental Sciences Center (UMESC) provided project coordination and compiled all project data for distribution. The UMESC produced all spatial database sets: vegetation map, observation points, vegetation sample plots, accuracy assessment sites, and various other supporting coverages. The UMESC also performed the accuracy assessment of the vegetation spatial database coverage, prepared final project documentation discussing methods and results, and provided metadata reports. The Nature Conservancy, NatureServe, and Maine Natural Areas Program provided ecological and vegetation support, vegetation field sampling (plot samples and accuracy assessment), data entry, vegetation analysis, methods and results documentation, and vegetation classification development (including vegetation community descriptions) based on the Federal Geographic Data Committee’s National Vegetation Classification Standard with floristic level types defined by NatureServe's International Vegetation Classification (association and alliance classes of the National Vegetation Classification System). Acadia NP provided staff to assist in field efforts including GPS navigation and collection, lodging, boat transportation, and knowledge of the local area. --- The Project provides a technical report with details regarding methods and results. Metadata documents are provided for the vegetation spatial database coverage (vegetation map), field reconnaissance observations, vegetation field plots (samples), accuracy assessment, aerial photography, and project boundaries.

   Other_Citation_Details:

   Overview of USGS - NPS Vegetation Mapping Program (taken from <http://biology.usgs.gov/npsveg/about.html>, May 2003): The USGS-NPS Vegetation Mapping Program is a cooperative effort by the U.S. Geological Survey (USGS) and the National Park Service (NPS) to classify, describe, and map vegetation communities in more than 270 national park units across the United States. This landmark program is both the first to provide national-scale descriptions of vegetation for a federal agency and the first to create national vegetation standards for its data products. Its goal is to meet specific information needs identified by the National Park Service. --- The vegetation mapping program is an important part of the NPS Inventory and Monitoring Program, a long-term effort to develop baseline data for all national park units that have a natural resource component. It is managed by the USGS Center for Biological Informatics, a unique information center designed to help scientists, land managers, the public, and others locate and apply biological information. --- Program activities are based on peer-reviewed, objective science. Comprehensive vegetation information is provided at national and regional levels, while also serving local management needs of individual parks. Stringent quality control procedures ensure that products are accurate and consistent for initial inventory purposes and replicable for monitoring purposes. The spatially enabled digital products produced by the program are available on the World Wide Web. --- Program scientists have developed data collection procedures for classification, mapping, accuracy assessment, and use of existing data. Program products meet Federal Geographic Data Committee standards for vegetation classification and metadata, and national standards for spatial accuracy and data transfer. Standards include a minimum mapping unit of 0.5 hectares and classification accuracy of 80% for each map class. Nature Serve, an important partner in the USGS-NPS Vegetation Mapping program, is the caretaker of the National Vegetation Classification System, which is used by the program to classify vegetation communities. --- A report of project methods and results is provided at completion of individual projects. Project results include a rich set of data and information for each park project, as follows: --- Spatial Data: Aerial photography, Map classification, Map classification description and key, Spatial database of vegetation communities, Hardcopy maps of vegetation communities, Metadata for spatial databases, Complete accuracy assessment of spatial data, Vegetation Information. --- Vegetation classification: Dichotomous field key of vegetation classes, Formal description for each vegetation class, Ground photos of vegetation classes, Field data in database format.

1. How well have the observations been checked?

   Based on results of a thematic accuracy assessment, the estimated overall accuracy for map classes representing National Vegetation Classification System (NVCS) natural/semi-natural associations (vegetation communities) is 80%, with a kappa index of 79%.

2. How accurate are the geographic locations?

   Photointerpretation data were spatially referenced by method of transferring photointerpreted polygon data to USGS 1:12,000-scale orthophoto base maps (hard copy maps plotted from 3.75-minute digital orthophoto quadrangles, DOQ). The map coverage is assumed to have a positional accuracy meeting U.S. National Map Accuracy Standards for DOQ maps.

3. How accurate are the heights or depths?

4. Where are the gaps in the data? What is missing?

   All data within the bounding coordinates are complete with polygons representing ground features at the time of aerial photographs. Each polygon is represented with an attribute in the form of a code that represents the map class and any special modifier classes when applicable. This attribute label is cross-referenced within the database attribute table, providing reference to other established classification systems, including all physiognomic and floristic levels of the NVCS. A 0.5-hectare (1.25 acre) minimum mapping unit was applied to all map classes, except for the small island categories, which were mapped to 0.1 hectares (0.25 acres).

5. How consistent are the relationships among the observations, including topology?

   All polygon features were checked for topology and existence of label points using ArcInfo (Version 8.0.2). Each polygon begins and ends at the same point with the node feature. All nodes were checked for error so that there are no dangling features. There are no duplicate lines or polygons. All nodes were snapped together and polygons closed based on a specified tolerance. The tests for logical consistency were performed in ArcInfo.

Are there legal restrictions on access or use of the data?
