So I'm writing a Javascript library that takes x,y coordinates and uses them to draw a map of the US. To do this, I need to find the coordinate data necessary to draw each state. This map on Wikipedia is a great example of what I need, because the SVG file contains the shapes that make up each state nicely labeled: http://upload.wikime...
Hi, I'm trying to put a bunch of (x,y) points on a map, that have a lon-lat origin. I'd like to set up a custom Transverse Mercator projection, centred on my origin, and use that to project my points into lon-lat. This seems like the sort of thing that GeoToolkit (or GeoTools) should be able to do, but I'm having great difficulty in de...
I am building a Tile Overlay server for Google maps in C#, and have found a few different code examples for calculating Y from Latitude. After getting them to work in general, I started to notice certain cases where the overlays were not lining up properly. To test this, I made a test harness to compare Google Map's Mercator LatToY con...
I have OpenLayers map with two base layers: MetaCarta (EPSG:4326) and Google map (Mercator). sphericalMercator = false, units are degrees. There are also some markers, boxes, and vector data on the map. When I switch between the base layers (which are of different projections), the simple geometries (such as markers or boxes) are reproj...
