I'm sitting with a task that I cannot get my head around:
I have a polygon theme of buildings that I first of all would like to make 'coarser', i.e. buildings within a certain distance of each other should be combined to a single large structure. Secondly I need to create an inside boundary in each of the buildings (red line in the image).
My first thought was to buffer the theme and dissolve all overlaps. I am aware that this will make the buildings extent to a larger area than they actually do, but this is ok for now. Then I would create an inside buffer to make the red line boundary.
The problem is that I cannot seem to be able to create square buffers. One solution I have found on the www is to first create a buffer, then use the feature envelope to polygon tool. However this solution doesn't work for this case, as the latter tool creates straight north-south 'pointing' rectangles. The same goes for creating the inside boundary.
Does anyone have any ideas of how I can solve this?
In regards to your issue with the symbology, please try the following:
1. Open the Layer properties of the polygons > Symbology Tab 2. Select the Symbol > Edit Symbol... 3. Click the Add Layer (Plus sign) button, change the Color to No Color > Click Outline... > Edit Symbol... 4. Change the type to Cartographic Line Symbol > Line Properties Tab > Give the Line a negative offset > OK
