The data are then converted to unprojected ArcView Shapefiles using the ArcSDE utility 'sde2shp' and then inserted into the National Shapefile Repository at the county and state levels for each state. Positional and attribute accuracy are verified by taking independent samples of the data, viewing the data using ArcView, and comparing the displayed data with matching records from Envirofacts. Log files are created during the extraction of data from the EF Oracle database and conversion to Shapefiles. These files are created to monitor and verify that the processing occurred without error. 1200 Pennsylvania Ave.
