SAMPLE_PT: This dataset represents monitoring and sample locations (points). Monitoring is a generic term describing various kinds of assessments that the BLM makes on public land natural resources and/or management actions undertaken. The SAMPLE_PT dataset represents places where a measurement of some type has occurred. Examples of measurement types are: vegetation transects or plots, soil pit descriptions, and observations/photos of resource use or impact. For full documentation see SAMPLE POINTS SPATIAL DATA STANDARD. https://www.blm.gov/about/data/oregon-data-management
SAMPLE_PT is BLM corporate data to be collected and maintained in support of Land Use Management.

This dataset is used to depict sample points on maps. For any particular area or resource, the dataset shows all types of monitoring and sampling that has occurred. In addition, for any particular type of sampling, the dataset lists all the sample locations with basic information about type and methodology, along with the date the sample point was established and last date it was visited. The dataset does not provide the actual, measured values because the source material is continually updated. A published revision of the Department Manual’s Part 305: Departmental Science Effects, Chapter 3: Integrity of Scientific and Scholarly Activities (305 DM 3), effective December 16, 2014, is available online at http://elips.doi.gov/ELIPS/DocView.aspx?id=4056. Scholarly information considered in Departmental decision making must be robust, of the highest quality, and the result of as rigorous scientific and scholarly processes as can be achieved. Most importantly, it must be trustworthy. This policy helps us to achieve that standard (http://www.doi.gov/scientificintegrity/index.cfm)

o Description: Instance of Sampling group. o Geometry: Points may be coincident. o Topology: No. o Integration Requirements: None.
Data is updated annually, after field season or as needed. Also, it is archived annually, at the end of the fiscal year.
Required attributes have an accuracy of at least ninety percent. Sample points require a high level of positional accuracy (generally within 50 feet) in order to be useful for intended purposes. A sample point represents the location of specific measurement of a particular resource at a point in time. The resource being measured may not even exist in a different (even if nearby) location. It may be critical that a point is located on one side or the other of a stream or road. There may be many sample points close together and different Global Positioning System (GPS) locations obtained with every visit. Accurate location is critical to being able to distinguish points that are supposed to be different from points that are supposed to be in the same location
Unknown
Most monitoring and sampling points are input from GPS coordinates or using Digital Raster Graphic (DRG) or Digital Orthoquad (DOQ) backdrops for heads-up digitizing. Some are digitized from paper maps. The source of the coordinates is captured in the attribute COORD_SRC. The data does not provide the actual, measured values because there is an increasing number of measurements over a range of dates.

ACCURACY_FT
Accuracy (ft)
How close, in feet, the spatial GIS depiction is to the actual location on the ground. There are several factors to consider in GIS error: scale and accuracy of map-based sources, accuracy of GPS equipment, and the skill level of the data manipulators. A value of “0” indicates no entry was made. This is the correct value when the COORD_SRC is another GIS theme (Digital Line Graphs (DLG), Geographic Coordinate Database (GCD), and Digital Elevation Model (DEM)) because the accuracy is determined by that theme. However, if COORD_SRC is MAP (digitized from a paper map) or GPS, a value of “0” indicates a missing value that should be filled in either with a non-zero number or “-1.” A value of “-1” indicates that the accuracy is unknown, and no reliable estimate can be made.
