I want to create a repeating pattern of raster OR polygon features based on an existing sample, so that the sample fills up a larger area in a repeating pattern. For example, with a sample of 10x10 units I want to fill an area of 100x100 units with 100 samples.

The sample area is to fill a given area, used as a mask later

The goal is to create a mask of repeating pattern, similating a specific landscape type or pattern. This mask is then to be clipped by polygons to fit in a map, used for landscape change and connectivity analysis.

I have browsed around existing tools, but the only way I have found so far is to manually copy+paste the feature x times, risking both inconsistency and topological errors.

  • Are you wanting to do this in ArcGIS for Desktop or QGIS the most? So that you are asking a single focussed question (not one for each of two products) please choose one or the other to prevent your question being too broad. – PolyGeo May 15 '16 at 9:41
  • I suspect this is an example of an XY Problem. There are many potential ways to construct fill patterns that do not require this solution. You might get a better answer if you ask about the problem, not your proposed solution. – Vince May 15 '16 at 14:24
  • Ok. Specified to ArcGIS in the question. Thank you. – Rasmus Gustafsson May 15 '16 at 14:25
  • Vince, regarding the XY problem. I do not know how to start solving the problem and are happy for any suggestions. I have tried to specify the problem and the broader picture in which it is to be used. Thank you. – Rasmus Gustafsson May 15 '16 at 14:30
  • That's not how things work here. We need a focused, well-described problem statement so that a solution can be generated. – Vince May 15 '16 at 16:51

You could use the the original raster image and replicate it in a image processing tool like gimp (see instructions under this link) Afterwards you adjust the header information of the new raster image multiplying the extent by the amount of replicates.

However, I am sure this would also by possible in ArcPy.
