The WGS_1984_Web_Mercator_Auxiliary_Sphere coordinate system is a PROJECTED coordinate system, its units are METERS. Your coordinates are read in meters so they fall near the origin of the coordinate system which is the meeting of the equator and the Greenwich meridian. If you want to map Lat/Long coordinates (degrees), use a GEOGRAPHIC coordinate system ...

The number comes from the tile resolution being set at a multiple of 256 pixels, and from the screen resolution (96dpi). Per Bing's page about their map tile system: The map scale indicates the ratio between map distance and ground distance, when measured in the same units. For instance, at a map scale of 1 : 100,000, each inch on the map represents ...

Upon further inspection of Oracle's Nashorn documentation I found that Nashorn doesn't support 'objects normally supported in web-browsers' such as window and console. Well that is too bad. For more information you can find it here, right before the section titled ...

Your project (*.mxd) can be projected in any projection you want, but the coordinates of Google Earth are in Geographic (WGS84). So when you plot your points must define the correct projection. Then you can export it to shapefile and reproject to the project projection system.

The best tool for coordinate conversion is GDAL's cs2cs. The Lo 22/19 coordinate system is defined by EPSG code 29379, so the command line should be: cs2cs +init=epsg:29379 +to +init=epsg:4326 namibia_in.txt >>namibia_out.txt with this input file namibia_in.txt: 55435.89 -498157.28 Note that your coordinates are named Y;X but have to be ...
