To learn more, see our tips on writing great answers. If you are not using the data for web mapping, I would strongly encourage you to consider some other projection that is more suitable to your use-case, especially if you intend to do distance calculations (or, in that event, cast your data in geographic coordinates and not Cartesian coordinates and use the Haversine formula to calculate distances on a sphere).

Please keep in mind to only use this rule in not too big areas! Alternatively we could always transform to the Google Mercator (EPSG:900913), but we fear for the precision. How to add meters to EPSG:4326 coordinates? ), at which point you would need to start working with non-pseudo projections. Do you doubt that the unit of measure is meters, or the extent of the projected bounds? Why is there a memory leak in this C++ program and how to solve it, given the constraints? What are some tools or methods I can purchase to trace a water leak? layer, provided a set of projection databases. (e.g. For each point, I want to find all points that are roughly within a 1km box centred on that point (so selcet a.id, count(*) from nodes as a, nodes as b where SOME_DISTANCE_FUNCTION_HERE(a.point, b.point, 1000) group by a.id;. To get the actual underlying projected CRS, you can use the .source_crs attribute: Now we have a Projected CRS, and now it will also recognize the correct EPSG UoM: m. Covered area powered by MapTiler Center coordinates 1287295.73 5446267.2 Projected bounds: 1087830.41 5316153.83 1478210.83 5584166.14 WGS84 bounds: 16.84 47.73 22.56 49.61 Slovakia.

Datum transformations set in the Settings Basically I have a table (nodes) with a POINT column (point). That is because of distortion in the transformation. The value -95.5 can be represented 95.5W, 95.30W, 95.30.00W, and -5730 minutes and still represent the same angle. Geological Survey Open-File Report 90-284, 1990 (available at to overlay them regardless their original CRS.
