Title: BLM OR Monitoring & Sample Point
Originators: Bureau of Land Management
Publication date: 20141009
Data type: vector digital data
Description
A characterization of the data, including its intended use and limitations.
Abstract:
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. http://www.blm.gov/or/efoia/fy2012/im/p/im-or-2012-051.pdf
Purpose:
SAMPLE_PT is BLM corporate data to be collected and maintained in support of Land Use Management.
Supplemental information:
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.

ACCURACY_FT
Definition:
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.

Data Quality and Accuracy Information
General
Information about the fidelity of relationships, data quality and accuracy tests, omissions, selection criteria, generalization, and definitions used to derive the data.
Completeness report:
Data is updated annually, after field season or as needed. Also, it is archived annually, at the end of the fiscal year.
Attribute Accuracy
Accuracy of the identification of data entities, features and assignment of attribute values.
Attribute accuracy report:
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
Data Source and Process Information
Process Steps
Information about events, parameters, tolerances and techniques applied to construct or derive the data.
Process step information
Process Step 1
Process description:
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.

Metadata Standards
Description of the metadata standard used to document the data and reference to any additional extended profiles to the standard used by the metadata producer.
Standard name: FGDC Content Standard for Digital Geospatial Metadata
Standard version: FGDC-STD-001-1998
Time convention: local time
FGDC Plus Metadata Stylesheet
Stylesheet: FGDC Plus Stylesheet
File name: FGDC Plus.xsl
Version: 2.0
Description: This metadata is displayed using the FGDC Plus Stylesheet, which is an XSL template that can be used with ArcGIS software to display metadata. It displays metadata elements defined in the Content Standard for Digital Geospatial Metadata (CSDGM) - aka FGDC Standard, the ESRI Profile of CSDGM, the Biological Data Profile of CSDGM, and the Shoreline Data Profile of CSDGM. CSDGM is the US Federal Metadata standard. The Federal Geographic Data Committee originally adopted the CSDGM in 1994 and revised it in 1998. According to Executive Order 12096 all Federal agencies are ordered to use this standard to document geospatial data created as of January, 1995. The standard is often referred to as the FGDC Metadata Standard and has been implemented beyond the federal level with State and local governments adopting the metadata standard as well. The Biological Data Profile broadens the application of the CSDGM so that it is more easily applied to biological data that are not explicitly geographic (laboratory results, field notes, specimen collections, research reports) but can be associated with a geographic location. Includes taxonomical vocabulary. The Shoreline Data Profile addresses variability in the definition and mapping of shorelines by providing a standardized set of terms and data elements required to support metadata for shoreline and coastal data sets. The FGDC Plus Stylesheet includes the Dublin Core Metadata Element Set. It supports W3C DOM compatible browsers such as IE7, IE6, Netscape 7, and Mozilla Firefox. It is in the public domain and may be freely used, modified, and redistributed. It is provided "AS-IS" without warranty or technical support.
Instructions: On the top of the page, click on the title of the dataset to toggle opening and closing of all metadata content sections or click section links listed horizontally below the title to open individual sections. Click on a section name (e.g. Description) to open and close section content. Within a section, click on a item name (Status, Key Words, etc.) to open and close individual content items. By default, the Citation information within the Description section is always open for display.
