FS_FSTOPO.Ownership_P
map
Ownership_P portrays land that is not owned by the Forest Service within the Proclaimed Forest boundary. The line feature class was derived from the Cartographic Feature File (CFF). The source for updates is the BasicOwnership feature class from the Automated Lands Program (ALP).Within the FSTopo database, features are represented as lines, points, or polygons, with descriptive subtype attribute codes attached to describe the cartographic symbology characteristics of features. Annotation features are represented as stand-alone map text collected relative to the scale of the topographic quadrangle. The FSTopo database was originally populated with Cartographic Feature File (CFF) data which was digitized from either the Primary Base Series (PBS) quadrangles or U.S. Geological Survey (USGS) topographic map series quadrangles. Over time, the legacy CFF data is being replaced (at least partially) with data from nationally standardized sources. Data completeness reflects the content of the original source graphic, digital correction guide information, stereoscopic source, monoscopic source, supplemented with cadastral source information. Forests and Quadrangles may have undergone revision at varying dates. The update revision uses a variety of sources, including Digital Orthophoto Quad (DOQ) imagery, NAIP imagery, cadastral information, other vector data sources, and field-prepared correction guides in hardcopy or digital format.
The FSTopo cartographic database supports a web application that enables the creation and downloading of 1:24,000-scale, 7.5-minute topographic PDF maps for the conterminous United States and Puerto Rico, and 15 minute x 20-22.5 minute, 1:63,360-scale maps over Alaska. The FSTopo Area of Interest covers the USFS National Forests and Grasslands. The cartographic database is updated accordingly as new data sources are added by means of data revision activities, which are coordinated between the National Forest/Grassland units and the USFS Geospatial Service and Technology Center (GSTC).
The FSTopo database was originally populated with Cartographic Feature File (CFF) data which was digitized from either the Primary Base Series (PBS) quadrangle or, if not available, U.S. Geological Survey (USGS) topographic map series quadrangle. Over time, the legacy CFF data is being replaced (at least partially) with data from nationally standardized sources. Features were constructed to meet National Map Accuracy Standards, which require that 90 percent of all well-defined features shown on the map are within .02 inches of their true location. At a scale of 1:24,000-scale, .02 inches represents 40 feet on the ground. Digitizing was performed by the USFS Geospatial Service and Technology Center.
The data was produced by one of the following methods: 1) Scanning a stable-based copy of the graphic materials. The scanning process captured the digital data at a scanning resolution of 0.001 inch or less; the resulting raster data were then manually digitized and attributed on an interactive computer editing station. 2) Manually digitizing from a stable-based copy of the graphic material using a digitizing table to capture the digital data. Typically, digitizing tables had a resolution of .001 inch, with a statistical repeatability of .003 inch. Attribution was performed as the data were digitized on an interactive edit station. Four control points corresponding to the four corners of the quadrangle were used for registration during data collection. A four-parameter affine transformation was performed from the processing software internal coordinates to State Plane (NAD 27) grid coordinates. The data was checked for positional accuracy by one or more of the following processes: comparing plots of the digital data to the graphic source, comparing the digital data to the digital raster scan, comparing the digital data to the graphic source.
The original data was collected in State Plane (NAD 27) coordinates and databased in Geographic (NAD 27). It has since been converted to Geographic (NAD 83). Revisions to the data are performed in UTM (NAD 83).
The attribute accuracy was tested by one or more of the following methods in accordance with the data vintage: feature comparison with aerial photography, color display of CFF on interactive computer graphic system; manual comparison of the source with hard-copy plots; symbolized display of CFF on an interactive computer graphic system; selected attributes that could not be visually verified on plots or on screen were interactively queried and verified on screen. All attribute data conform to the attribute codes as of the date of digitizing.
Thematic and feature level metadata will be updated accordingly as new data sources are added to the FSTopo database by means of data revision activities, which are coordinated between the National Forest/Grassland units and the USFS Geospatial Service and Technology Center (GSTC). Data themes are updated by request of the unit using USFS corporate data, such as Cadastral data fromthe Automated Lands Program and Road, Trail or Recreation data from the Infra database. Local, County and State data is used for areas outside the proclaimed forest extingding the data to the Quadrangle's outline/footprint.
