CRS and EPSG correspondences

crsEpsg

This is a simple python package that contains two dictionaries - i.e., crs2epsg and epsg2crs- with the correspondences between the CRS names and EPSG codes. For instance,

crs2epsg = {
"Anguilla 1957 / British West Indies Grid":"2000",
"Antigua 1943 / British West Indies Grid":"2001",
"Dominica 1945 / British West Indies Grid":"2002",
...
}

epsg2crs = {
"2000":"Anguilla 1957 / British West Indies Grid",
"2001":"Antigua 1943 / British West Indies Grid",
"2002":"Dominica 1945 / British West Indies Grid",
"2003":"Grenada 1953 / British West Indies Grid",
...
}

I created this package to use it with las/LIDAR files, so, I included the function getEPSG(filename, default) that return the EPSG code from a las/LIDAR file. Some files contains larger CRS name (e.g., "ETRS89 / UTM zone 30N + Geoid" when the documented name is only "ETRS89 / UTM zone 30N"), so, this function will be cutting the last word until achieve the good portion of the CRS name.

from crsEpsg import getEPSG
print("EPSG:", getEPSG("data/209341.las","32718"))

Requirements
