[Qgis-user] Export polygon coordinates qgis
Hello, I need to export polygon coordinates from shp to text file. I can mark an object on map and use Ctrl+C but only x y coordinates are copied. How can I recalculate X Y coordinates to get lat/long geographical coordinates? I'd prefer to do it in Excel, because have a lot of extracted X Y data.

Re: [Qgis-user] Export polygon coordinates qgis
Hi Lester, Thanks, it works but… I still get XY coordinates, not lat/long. The question i show to convert from XY to lat/long ?

Go into edit mode and select the feature(s) you want (highlighted yellow usually). Open the attribute table for the polygon shapefile and click copy slected rows to clipboard (4th icon from the right on the toolbar). Copy this into a text editor and you get something like this: wkt_geomid POLYGON((-2.72439024390243922 1.60975609756097571,-2.72439024390243922 1.95121951219512213,-1.77073170731707341 2.02926829268292686,-1.57073170731707323 1.42926829268292699,-2.21951219512195141 1.06341463414634152,-2.72439024390243922 1.60975609756097571))1 Just edit this file to leave the X, Y coordinates and away you go! Coordinate pairs are separated by commas.

Re: [Qgis-user] Export polygon coordinates qgis
The important point is to make sure the shapefile is in a proper projection and not just a cartesian reference. Then you can export the vertices after reprojecting. There are other ways to do this via GMT too.

To get lat/long in geom field you need to explicitly reproject layer with vector or processing tool. Reproject on the fly does not apply on copy paste geom field.

Re: [Qgis-user] Export polygon coordinates qgis
You can right click on the layer and choose save as. Then select save to csv. Select save selected if you only want a selection and select AS_WKT to get the coordinates. Then select the CRS in this case something like 4326 to get longitude latitude coordinates.

Have you assigned a projection to your shapefile? On 17 March 2015 at 08:59, Tomasz Bigaj to...@jagielka.eu wrote: Hi Lester, Thanks, it works but… I still get XY coordinates, not lat/long.
