A Distance query
 uses the "shape" data from two themes to find records in the "source" theme that are within a given distance from the "selection" theme. For example , you might want to find all wells that are within 1000 feet of a pipeline theme.
The following example shows finding all wells within 700 feet of a section line. The original "PetraWells" theme was selected as the "current" theme, thus becoming the "source" theme. The "SECTIONS" theme was used as the "selection" theme.
When you perform a distance query using a dataset (shape file) containing latitude-longitude data, you will receive the following warning that the distance query is only an approximation due to the variation in the number of feet (or meters) per degree at different locations on the earth.
The selected wells were then saved as the "Edge Wells 1" theme (shown in yellow).
