I found a Python Library called utm 0.5.0. The conversion.py module in that library seems to do the trick. I've modified the code by removing the reference to numpy and the custom OutOfRangeError library. import math as mathlib __all__ = ['to_latlon', 'from_latlon'] K0 = 0.9996 E = 0.00669438 E2 = E * E E3 = E2 * E E_P2 = E / (1.0 - E) SQRT_E = ...

As @Vince suggested, Google Maps uses WGS84. And as @mkennedy pointed out, the SRID of WGS84 is 4326 (epsg-registry.org). Therefore, the SQL to generate the hyperlink/URL would be: select 'http://maps.google.com/maps?q=' || chr(38) || 'layer=c' || chr(38) || 'cbll=' || latitudey_dd || ',' || longitudex_dd as street_view_url from ( select ...

Just a sample... You could just divide by 10000000 and that'll work latitudeE7 = c(205912610, 205913478) longitudeE7 = c(-1034513483, -1034513949) coords <- data.frame(latitudeE7, longitudeE7) coords / 10000000 latitudeE7 longitudeE7 1 20.59126 -103.4513 2 20.59135 -103.4514

I tried several coordinate systems for Florida and the various State Plane Florida East zone but the coordinates just didn't seem to fit. Google kept finding the address in Hempstead, NY, so I tried the Long Island zone, unit of US survey feet, and the results look good. Try EPSG::6539 for the NAD83 (2011) version or EPSG::2908 for NAD83 (HARN). For the ...

This error is extremely confusing, but it is thrown when the in- or output projection is not set. Check your crs and crsGeo to check if they are not an empty. If so, try updating pyproj, setting your PROJ_LIB correctly etc.
