STATUS INFORMATION
Completion Status:  Completed
Completion Date:  October 5, 1997
Geographic Area Completed:  Dixie Valley, Nevada
Update Frequency:  Not updated since completion
Release Information:  Not proprietary

ACCURACY INFORMATION
RMS Error:  0.006
Accuracy Checked: yes
Accuracy Information Source:  analog map
Spatial Accuracy: Good in relation to analog base map. As no projection
              parameter were available spatial accuracy is dubious. 
Thematic Accuracy:  Good - no errors found
