Trick: Finding "bad" coordinates
Sometimes, and with data from other sources, the coordinates might not convert properly.
To find these types of bad coordinates, you can try two different techniques.
Technique 1: using the Catalog Search function, perform the Bounded Coordinate search. This allows you to specify a central coordinate and a radius around that coordinate. Bad coordinates are assigned a Lat/Lon of (0,0). Using this as the central coordinate, the results of the search will be all those logs that were identified as having a bad coordinate.
Technique 2: Sometimes, the coordinate is "bad", but may actually look reasonable. It is possible that a State Plane northing or easting was entered into the wrong data entry field, or the State Plane Zone was specified incorrectly. You can identify logs that are not within an area of interest by defining a polygon (see the User's Manual for details). It can be as simple as a polygon drawn with Google Earth, or you can hand-enter coordinates. In either case, searching for any logs OUTSIDE of the polygon will identify the outliers. And, you can also refine the search terms to include the quadrangle name or state to further restrict the possible "false positives".
To flag this for new data, you can define a polygon as an "area of interest" and specify this in your configuration file. If during data entry (or data importing) the coordinate falls outside this polygon, it will be flagged as an outlier.
