Enter Meters: or Arc-Seconds: Enter Latitude: m km arc-seconds arc-minutes degrees Calculate Meters Calculate Arc-Seconds. First you need to reproject the GeoDataFrame to a different CRS which units is either meter or feet, and then measure the area using areaattribute. 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. PS: EPSG:4326 is using degrees as units, try the EPSG:3857 which uses meters as unit or if you know the location of your polygons choose a projection from a national gridI have 50% polygon data in EPSG:25832. Rasters are composed of rectangular cells of the same size (expressed by map units, such as degrees or meters), so it is usually impracticable to transform coordinates of pixels separately. 000000197720465). Engineering survey, topographic mapping. 788)',4326) , 100 ); It takes the 3rd parameter (100) as 'degree' , so it returns all data , I have to narrow down to 0. I'm currently trying to figure out how vesselfinder. From the doc I know that res returns the (width, height) of pixels in the units of its coordinate reference system. Now, let's look at the geometry and geography types. 1353377°) Maybe your source coordinate is inaccurate because it is not in the area where the coordinate system is used. Ghana - onshore. CRS. Notable components of this CRS description include the EPSG code (EPSG: 27700), the projection (transverse Mercator, +proj=tmerc), the origin (+lat_0=49 +lon_0=-2) and units (+units=m). 37477m, dZ=+21. The equation from converting degrees to meters becomes: (3) L ( m) = r × π × α ( d e g) 180. You can add any you need to that list or make your own. 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.
