- Title:
-
Pipe Spring National Monument Vegetation Mapping Project - Field Plot and Observation Points
- Abstract:
-
This point feature class contains points representing field sample data (3 plots points and 4 observations points, collected August 2007 and September 2008) for the vegetation mapping project at Pipe Spring National Monument. Field photos are associated with each plot or observation location.
- Supplemental_Information:
-
To update the hotlinks to plot photos, update the PHOTO_PATH field in TBL_PHOTOS with the directory path where the photos are stored (e.g., Calculate: PHOTO_PATH = "C:\GIS\Parks\PISP\Vegetation\Photos\"& [IMAGE_ID]).
- How should this data set be cited?

Plots were collected to characterize the vegetation at Pipe Spring National Monument. The intended use of all data in the park's GIS library is to support diverse park activities including planning, management, maintenance, research, and interpretation.
- From what previous works were the data drawn?
- DRG (source 1 of 1)
-
USGS, varies, Pipe Spring.
- Type_of_Source_Media: CD-ROM
- Source_Scale_Denominator: 24,000
- Source_Contribution: Digital Raster Graphics were used for field maps.
- How were the data generated, processed, and modified?
- Date: unknown (process 1 of 3)
-
Field data collection was accomplished with the use of recreational GPS units (generally Garmins). Field crews used their judgment for the placement of plot and observation locations.
- Date: unknown (process 2 of 3)
-
Data was entered into the NCPN Plots (Microsoft Access) database, quality checked, and then shapefiles were created from the data in the database.
- Date: unknown (process 3 of 3)
-
Shapefiles and database data were migrated to a personal file-based geodatabase format.
- What similar or related data should the user be aware of?

- How well have the observations been checked?
Network staff has ground checked and verified all features to the best of their knowledge. GIS personnel verified all features and attributes.
- How accurate are the geographic locations?
This data was collected using recreational grade GPS receivers (Garmin GPS12). A DOP or meters error reading was recorded when applicable. Recreational GPS receivers generally have horizontal errors of 3-15 meters (less than 40 meters). GPS accuracy varies for each plot. Error values were recorded on the plot form.
- How accurate are the heights or depths?
Standard GPS Elevation Error
- Where are the gaps in the data? What is missing?
This data contains all the observation and plot points visited for the Pipe Spring Vegetation Mapping Project.
- How consistent are the relationships among the observations, including topology?
There are no duplicate features present.
Are there legal restrictions on access or use of the data?
