EPSG:2537 Projected coordinate system for Kazakhstan, Russian Federation onshore, Turkmenistan and Uzbekistan - between 61°30'E and 64°30'E. For instance, the common WGS 84 latitude/longitude CRS is known by the identifier EPSG:4326, and the web mapping standard CRS is EPSG:3857. pointid distance lat long where pointid is a list of points, distance is distance of point from feature (calculated in QGIS in geographical units under a. gdaltransform -s_srs epsg:4326 -t_srs epsg:3857 10 30 1113194. Replaced by Xian 1980 / 3-degree Gauss-Kruger zone 38 (code 2362). 1) Your query is correct but you coordinates are inverted. There are only entries for EPSG:2400,3006 and 4326. 4336819°, 4. As a rough estimate, at the equator, 1 degree of latitude is approximately 111 kilometers, which is roughly equivalent to 111,000 meters. The default CRS is set to EPSG:4326 – WGS 84, for both layer and the project (checked in bottom right), and unit is thus in degrees. But. That doesn't change anything to my. Find a coordinate system and get position on a map. Replaced by Xian 1980 / 3-degree Gauss-Kruger zone 40 (code 2364). Transforms coordinates of object to new projection. the CRS is EPSG:4269 - NAD83 - Geographic; the unit is in degrees; and I confirmed from a metafile somewhere that the height z axis is in meters; 3. So if I tell the library I want a buffer with a distance of 5 it will give me back a buffer with a radius of 5 degrees around my point. -. from shapely. if you are not at the equator (and even if you are, but then the difference can be neglected in most applications), then 1 degree of latitude does not represent the same distance on the surface of the Earth than 1 degree of longitude. Perhaps, Openlayer's implementation can be interpreted as: if EPSG:4326 is specified as a projection, OL will handle it in some manner. The coordinates in (SRID) 900913 are easting/northing, and they are in meters. By default the layer use EPSG:900913 and the coordinates are in meters.
