Create new polygon layers from postcodes latitude & longitude

I'm running QGIS 1.8.0

I have a list of points that I need to convert to one polygon. So far I have been using the Point2One plugin which produces a zigzagged polygon, instead of one full polygon.

To change the output result, I modified the numerical order of the ID column in the dbf to connect points in order yet I still get the same result.

The "Create output features based on input field" or "Sort points by this field" yields an error

I've looked at Createing polygon layer from point data using QGIS? but my problem seems a bit different.

I thought converting these points to a csv or txt format might work.

This seems like fairly easy problem to solve but I'm hung up. Any suggestions?

Thanks all!

  • Is there an order to your points or do you want a convex hull? Maybe post a link to an example of what you are looking for. – underdark Nov 26 '12 at 23:07
  • Check this question I helped some earlier. There does appear to be a problem(not sure) with convex hull in 1.8 that we adress in the answer. http://gis.stackexchange.com/questions/41985/create-new-polygon-layers-from-postcodes-latitude-longitude/42002#42002 – RomaH Nov 26 '12 at 23:11
  • There's an order to the points which I used to reorder in the ID column. The result would be a simple, closed polygon shape. – Zach Nov 26 '12 at 23:11
  • @RomaH, convex hulls works. Problem solved. Thanks all! – Zach Nov 26 '12 at 23:17
