Then try your. 788)',4326) , 100 ); It takes the 3rd parameter (100) as 'degree' , so it returns all data , I have to narrow down to 0. If you want meters, you'd need a projected coordinate system. 384 km, it will only create a grid square size of 10 km. hence you area will in in km^2. from shapely. I simply cannot figure out why the units are meters and not degrees when native EPSG is 4326? In the past when I have published layers as 4326, DWITHIN always took only degree units. United States (USA). The most commonly used coordinate systems are the WGS 84 Long Lat (SRID=4326) spherical coordinate system and the Mercator (EPSG:3785) projected coordinate system. A real value specifying the nominal grid distance in the y-direction where the map scale factor is 1. The following example converts the station coordinates of two German stations to the regionally used Gauß-Krüger system. Zone width 3 degrees. Cadastre, engineering survey, topographic mapping (large scale).
