Attribute Accuracy:
Attribute Accuracy Report:
Topology and attributes for this theme were manually checked by comparing plots of the processed data against original materials. Attribute accuracy information for source materials were not collected since acquisition of source data pre-dated FGDC metadata standards.
Logical Consistency Report: Polygon topology is present
Completeness Report:
The USGS 1:100,000 scale lakes cover was found to be missing some lakes, so data were added to it from other sources. The supplementary data were of 1:500,000 and 1:2,000,000 scales and were obtained from Gary Raines. The coarser data were only used where there was no overlap with the USGS data set.

Custom Order Process:
If unable to download data directly from the ICBEMP web site (www.icbemp.gov/spatial), follow these instructions for the manual ICBEMP data request process.
Complete and mail the Data Request Form and the Available Data List to ICBEMP, Attn: Carole Smith, c/o USDA Forest Service, 333 S.W. First Ave, 4th Floor, Portland, OR 97204 (Internet: c3smith@or.blm.gov). These forms are available from the Project web site or can be requested via e-mail from bgravenmier@fs.fed.us. Please specify requested datasets by placing a checkmark in the space provided on the Available Data List.
Spatial data are released in Unix ARC/INFO export format. ARCVIEW files are made available when applicable. The digital data are provided on 8mm tape unless otherwise specified. Please specify special instructions for export format and tape density on the request form.
The Bureau of Land Management (BLM) Oregon State Office will telephone the requester to advise the cost of requested data. The requested data are mailed to the requester after payment has been received by the BLM.
Cost is based on a manual labor charge of $20.00 per hour (prorated), cost of the tape(s), and size of the map/plot(s). Digital data are provided on 8mm tape (cost $9.00) unless special instructions are specified on the request form. Federal offices are provided the information free of charge.
Technical Prerequisites:
Spatial data are released as both compressed Unix-based archive ARC(.TAR.Z) export files and PC-based executable (.EXE) files. Attribute files are released in dBASE IV (.DBF) format as Unix-based archive (.TAR.Z) files and PC-based (.EXE) files. Additionally, databases are released in both dBase IV and Paradox (.DB) format as .TAR.Z and .EXE files. All files within the archive .TAR.Z files and .EXE files follow the 8.3 naming convention to enable use on the Windows 3.1 operating system.
