Bug fix: get-map-info.php
Some nodes returned a blank lat,lon and grid_square differently than others that were also blank. This was causing issues when writing to the SQL database. get-map-info would throw this error when it would happen: "Could not send to SQL. Incorrect double value: '' for column 'lat' at row 1" Fix: Any blank lat || lon now get converted to a single "0". Any blank grid_square now gets converted to a NULL.
