Recommended Posts

I have an excel spreadsheet full of post codes that I want to convert into points. If I download a raster map of the local area how would I georeference the postcodes to correlate on the map.

From my limited experience of doing this you will need to:

 

* Take the raster map with postcode detail's or some other feature/reference that matches your excel post code data and convert the raster and vectorise it (you may need to work out the table structure that you obtain from this process), so that you have some common features between the vector map and the postcode data.

 

* You will then need to match the vector map data table with the excel table be able will be able to get the centroids and make a point shapefile.

 

* Alernatively you can make a shapefile from the vector map and join the postcode data to it.

 

Which country are you working on?????
