I'm using ArcMap 10.2, and I need to map areas covered by London postcodes (E1 0xx, E1 1xx, E1 2xx, and so on). What I have is the coordinates for every single postcode (310,000 in total) in an Excel sheet, so I can create point feature classes, which I then want to group as explained above.

My question is, how can I create a polygon shapefile that will include a group of coordinates within E1 0xx postcode for example. I want that polygon shapefile to cover the are of those postcodes specifically. In the end I need to end up with multiple polygon shapefiles that will represent different Postcodes districts (E1 0xx, E1 1xx...). Tried the Coverage tool, but it's not seem to be doing what I expected it to. Just installed XTools Pro, maybe that could help me.

Help is much appreciated. Thanks

Would you be able to edit your Question to describe what you mean by coverage, please? I suspect that you are trying to get a tool working that will create output that is not what you are expecting. The term coverage can mean an old Esri vector format, or a raster format (as in Web Coverage Service), and there may be other meanings too. –  PolyGeo Apr 15 at 10:53
    
@PolyGeo - Just rephrased my question. I am afraid the Coverage Tool is not what I need. Was misguided by the standard meaning of coverage I think. –  user28424 Apr 15 at 11:05
    
This layer does not already exist as a polygon layer (e.g. shapefile)? –  artwork21 Apr 15 at 12:50
    
What do you mean? I only have the set of point as a point shp with all the coordinates. Where would it already exist as a polygon shp? –  user28424 Apr 15 at 13:04
