terrautils/betydb.py: add EPSG parameter to get_sites_by_latlon

[Chris-Schnaufer]

Tags: EPSG, Coordinate System, Spatial Reference

Description

get_sites_by_latlon() assumes epsg:4326 - matching what's in BETYdb. This means that non-EPSG:4326 values will fail to find qualifying sites.

Details

It was agreed that an EPSG code parameter should be added (see references below) with a default value of 4326. The lat-lon values are to be converted to EPSG:4236 before getting passed on.

Completion Criteria

• An EPSG parameter is added that defaults to 4326
• A conversion is done for non-EPSG:4326 lat-lon values
• The converted values are used for searching successfully
• Any returned geographic information is converted to the specified EPSG code
