Creating randomly shaped clumps of cells in a raster from seeds of 1 cell/pixel? @whuber I have added more detail as you have requested, but don't expect you to help me further if you don't want to. I really appreciate the amount of effort you have put in so far. Thanks. |

Creating randomly shaped clumps of cells in a raster from seeds of 1 cell/pixel? @whuber. Thanks again for the update. There is now the issue of clumps clashing, and resulting clumps sizing less than the number defined in size.clusters. How could I make sure a clump grows to the correct size, as, at the moment, I assume it tries to grow into an existing clump, fails, but still registers as a successful expansion. I then also intend to iterate the production of the 60 clumps 1000 times creating an average null model style dataset. Would the random positioning vary each time within a for loop? |

Creating randomly shaped clumps of cells in a raster from seeds of 1 cell/pixel? Hi Whuber. Thanks so much for this, I really appreciate it. I'm just experimenting for a bit and may come back with a few followup questions soon. |

Creating randomly shaped clumps of cells in a raster from seeds of 1 cell/pixel? I would also be happy to use ArcGIS or QGIS. Unfortunately I'm not that familiar with python. GDAL through a bash terminal is also a possibility. |

How to use GDAL to burn a selected value from one raster into another? What would the command be to apply the nodata values from 1 raster to the other then? |

A comprehensive, user-friendly GDAL manual? @R.K. The unknown territory I came across today was creation options, commonly used under the -co function I believe. In particular, I wondered which compression type to use for a GeoTiff. They are mentioned but not explained here - gdal.org/frmt_gtiff.html. I also don't understand where the utilities with .py extensions can be used. QGIS maybe? On a broader note, having never been formally taught GDAL I just find the utilities page a bit too technical. I guess my expectations are high, having used ESRI help pages for a while... |
