I am working with a number of very large 250m resolution raster files from the African Soil Information Service (AFSIS, http://www.isric.org/data/africa-soil-profiles-database-version-01-2) and would ...

more troubles in QGIS.
I georeferenced this raster in Corrego Alegre UTM23S and loaded up, so project CRS automatically changed to that. So far so good. I need it to be however in WGS84 UTM 23S. None ...

When I download a large map within R (using the openstreetmap package) and I reproject the map (ideally to +proj=longlat), the map will always turn out distorted, making country labels etc. near the ...

I created a polygon shapefile in QGIS. Projection was saved as EPSG: 3857, WGS 84 / Pseudo Mercator.
When I open this shapefile in ArcMap the projection sets itself as WGS_84_World_Mercator which I ...

Is it the case that when I use Arc GIS to compute nearest distance from a point to a poly-line/polygon, I need to project them both in an equidistant projection? Note: I am using the near tool.
What ...

I'm working with maritime sensors that give information of moving objects it detects, in azimuth, range and elevation, and we convert it to x,y coordinates for our application to be able to process ...

So I have a vector layer of polygons in WGS 84 lat/long (i.e. using the automatic projection for lat/long and WGS84 datum). I want to change that to WGS84 UTM 23S in QGIS. I tried doing like online ...

I have a set of locations/points and I am trying to compute the nearest distance of these points from a Polyline. The points and the polyline lie in China and the Geographic Coordinate System is WGS ...

I'm working on ArcMap 10 and need to get the lenghts (in meters) of the segments composing my line feature class. GCS of the line is WGS_1984. Extent of this data should be: Left 11.236520 dd, Right ...

I am attempting to extract from an image using Esri shapefile that is in the zip file RR_KZKD2012
In ArcGis the spatial reference is Projected Coordinate System: WGS_1984_UTM_Zone_43N.
Then am using ...

I'm working with ArcMap 10 and I have a feature points shapefile from the Florence (Italy) municipality open data (http://opendata.comune.fi.it/statistica_territorio/dataset_0040.html). Each point is ...

I have a table that has geometry column named the_geom. I set SRID value to 29903. And I used Openlayers api to view data on map. I set map srid as 29903 and works well.
But if I need to show my data ...

I am busy with a project where I have to layer a .dxf and a .kml file but the layers are not lining up. The .dxf file's coordinates are completely wrong and the scale also does not appear to math up ...

What is the best method for getting the radius of a circle in Openlayers 3 in epsg 4326 (geodesic)? I'm using this example for a base and trying to draw a circle while getting the radius, but using ...

I'm not quite sure if I'm phrasing this right. It's just occurred to me that lat/longs are two dimensional coordinates like any other projected coordinate system, so it's presumably possible to create ...

I am trying to do area computation stuff over whole of Indonesia and as such, am using the following projection:
http://spatialreference.org/ref/esri/asia-south-albers-equal-area-conic/
To make this ...

I'm creating a poster which has many separate maps (rivers of the world). I'd like to use a similar projection for each of them, so they're comparable in terms of shape and size. I guess I want some ...

I have two PRJ files, one from ESRI and another from some custom GDAL/OGR code I wrote (pasted below). I was trying to have both work in NAD83 UTM10N with the 2011 revision. The ESRI file has 2011 in ...
