So it wasn't actually a google maps API issue (which I couldn't tell from the console). 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 ...

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 ...

I believe it has to do with raster tiles, take a look at this answer (currently ranked 6th) to What ratio scales do Google Maps zoom levels correspond to?

On the page that you linked to, there is a note on the bottom: DATUM: SAD-69/original PROJEÇÃO CARTOGRÁFICA: UTM-22 (-51º) OBS.: Devido ao uso do DATUM SAD-69/original por Curitiba, para converter para SIRGAS-2000, devem-se utilizar os parâmetros locais de transformação de coordenadas descritos abaixo: SAD-69/original(Curitiba) -> ...

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 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 ...

I came back to this a year later and was able to solve it easily. I stored the current markers ID property in an array. Whenever the GeoJSON is requested the L.GeoJSON filter is used to check if the ID property of each incoming marker is in the array, returning true or false depending. When new GeoJSON is added, the markers in a GeoJSON group layer are ...

I calculated the scales for four zoom levels: Zoom level | Scale 20 1:500 19 1:1000 18 1:2000 17 1:4000 It seems that the scale is doubled as the zoom level increased by one step. So, I hope the scale for the zoom level 16 will be 1:8000 and so on.

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 ...

Two ways to minimize the size of each request. 1 - Make sure the polygon shapes are smoothed to the resolution. I.e. you don't need to show all the minute bends in the lake if you are viewing it at country level. So if you are going the JSON route, have different JSON files for different zoom levels. I found that having 3 different simplifications worked ...
