I want to set "EPSG:4326" as the projection of an OpenLayers map, but when I try it, I always get "EPSG:900913". function init() { var options = { projection: new OpenLayers.Projection("EPSG:4326") // ignored }; map = new OpenLayers.Map('map', options); var layer = new OpenLayers.Layer.OSM.Osmarender("Osmarender"); map.addLayer(layer); ... alert(map.getProjection()); // returns "EPSG:900913" ... } The base map is open street map. How can I set the Projection to EPSG:4326? It is Osmarender that has a hardcoded 900913 projection, nothing to do about that. But have you considered taking things

I'm pretty confused. I have a point: x= -12669114.702301 y= 5561132.6760608 That I got from drawing a square on a vector layer with the DrawFeature controller. The numbers seem...erm...awfull large, but they seem to work, because if I later draw a square with all the same points, it's in the same position, so I figure they have to be right. The problem is when I try to convert this point to latitude and longitude. I'm using: map.getLonLatFromPixel(pointToPixel(points[0])); Where points[0] is a geometry Point, and the pointToPixel function takes any point and turns it into a pixel (since the

I have a bunch of files with coordinates in UTM form. For each coordinate I have easting, northing and zone. I need to convert this to LatLng for use with Google Map API to show the information in a map. I have found some online calculators that does this, but no actual code or libraries. http://trac.osgeo.org/proj4js/ is a projection library for Javascript, but looking at the demo it doesn't include UTM projection. I am still pretty fresh to the entire GIS domain, so what I want is something ala: (lat,lng) = transform(easting, northing, zone) Staale I ended up finding java code from IBM that

I have the Lat/Long value of New York City, NY; 40.7560540,-73.9869510 and a flat image of the earth, 1000px × 446px. I would like to be able to convert, using Javascript, the Lat/Long to an X,Y coordinate where the point would reflect the location. So the X,Y coordinate form the Top-Left corner of the image would be; 289, 111 Things to note: don't worry about issues of what projection to use, make your own assumption or go with what you know might work X,Y can be form any corner of the image Bonus points for the same solution in PHP (but I really need the JS) A basic conversion function in js

I have this image: http://imgur.com/99tSz.png . A map of the UK (not including Southern Ireland). I have successfully managed to get a latitude and longitude and plot it onto this map by taking the leftmost longitude and rightmost longitude of the UK and using them to work out where to put the point on the map. This is the code (for use in Processing.js but could be used as js or anything): // Size of the map int width = 538; int height = 811; // X and Y boundaries float westLong = -8.166667; float eastLong = 1.762833; float northLat = 58.666667; float southLat = 49.95; void drawPoint(float
