I have a set of polygons of different shapes and sizes in shapefile1. 

What I need to do, is to create new polygons around the boundaries of the polygons in shapefile1, larger by x meters. Then, I need to compare this new polygons with another set of polygons in shapefile2 and see if the new ones are larger in AT LEAST one direction. How can I do it?

To recap, I would need:

  1. A way to create a new polygon from the perimeter of the existing polygons (I can't use the centroids because the shapes and the dimensons of the polygons are totally different);
  2. A way to assign the polygons in shapefile2 to each new polygon, (in this case I think I can use the centroids);
  3. A way to check if each polygon in shapefile2 (shp2) exceeds in at least one direction of the new one (new shp1).

Any suggestions?

Create a new polygon from antheranother one that is larger of "x meters"than the first by x meters

I have a set of polygons of different shapes and areassizes in a shapefile (let's say shp1)shapefile1. What I need to do, is to create a new polygon frompolygons around the perimeterboundaries of the shapepolygons in shapefile1, larger ofby x meters. Then, I need to compare this new polygonpolygons with anoter one in another shapefile (shp2)set of polygons in shapefile2 and see if the second one isnew ones are larger in AT LEAST one direction with respect to the other one. How can I do it?

To recuprecap, I would need:

  1. A way to create a new polygon from the perimeter of the existing polygons that exists   (I can't use the centroids because the shapes and the dimensondimensons of the polygons are totally different);
  2. A way to assign to each new polygons the polygons in shapefile number 2shapefile2 to each new polygon, (in this case I think I can use the centroidcentroids);
  3. A way to chekcheck if the secondeach polygon in shapefile2 (shp2) exceedexceeds in at least one direction of the new one (new shp1).
