After looking up the EPSG codes of source and target coordinate system, the conversion can be done in just a few lines of code. Similarly when I have changed the project CRS from EPSG:4326 to the recommended EPSG: 102033 (South America Albers Equal Area Conic), it still doesn't seem to fix the problem. 8. echo 616928 6877084 | gdaltransform -s_srs epsg:25829 -t_srs epsg:4326. GeoPandas can accept anything accepted by pyproj. But how do I directly pass meters as 3rd parameter. EPSG:22293 Projected coordinate system for South Africa. The following example converts the station coordinates of two German stations to the regionally used Gauß-Krüger system. Some examples of geographic coordinate reference systems: WGS84 (EPSG:4326), NAD83 (EPSG:4269), and NAD83(2011) (EPSG:6318), ETRS89 (EPSG:4258). EPSG:2633 Projected coordinate system for Russian Federation - onshore between 169°30'E and 172°30'E. , therefore you need to use preserve_units=True. It turns out I was attempting to intersect the 3857 projection with a 4326 projection later in my code. 001° of longitude. The default for other projections is to estimate the point resolution by transforming the 'point' pixel to EPSG:4326, measuring its width and height on the normal sphere, and taking the average. Cadastre, engineering survey, topographic mapping (large scale). May 20, 2013 at 20:53. Get the resolution of the point in degrees or distance units. Plot ID X_meters Y_meters M1 0. Mercator projection has an epsg code EPSG:4326. coordinates are in decimal degrees: latitudes and longitudes). You already had the right commands, if I'm not mistaken. Setting projIn is harder, because your netCDF file defines its coordinate system with a WKT string, which (I'm pretty sure) can't be read directly by proj4 or pyproj. projinfo -s EPSG:4326+5773 -t EPSG:4979 Operation No. EPSG:6933 has meters as unit epsg. 4326) A pyproj. from_user_input(): CRS WKT string.
