To convert your coordinate system from a geographic to a projected one. When you are referring to coordinates in a projected CRS, the terminology is eastings (x) and northings (y). 782683 ). I have a Series of locations in standart lat, lon float degrees format, and need to calculate buffer around them in meters. All the points are closely packed into a group like squares, so I would like to convert the lat,long points to meters so that I can plot it over the graph to see the variation in the heatmap. ArcGIS is sensibly not allowing you to do this, because if it did, you would get coordinates that represented the distance in meters from 0° longitude 0° latitude along an angular pathway. Crs coordinates are typically labeled x and y; in the case of EPSG:4326 (which is the same as WGS84) coordinates are provided in degrees in the common longitude and latitude definition. Sometimes the input is the SRS name "EPSG:4326", and the input coordinates then are given in degrees. Vector(new OpenLayers. 06) Lon(253457. Truncated form of Beijing 1954 / 3-degree Gauss-Kruger zone 28 (code 2404).
