Python GDAL: find out spikes and pits in DEM define 'spikes' and 'pits', and you'll find where to begin. |

Extraction of contour lines starting from 0 elevation Link the tutorials please. Also Qgis warps around gdal_contour command, so you might want to give gdal.org/gdal_contour.html a look. |

How do you use 'reclass' in GRASS? r.reclass only takes as input integer values (there's a reason for it),and to do it cast the value to int type. if you want to reclassify (values from x to y should be z) use r.recode |

Is it possible to use GDAL to combine (rather than mosaic) rasters You can do it with some python code. You can use itertools.product to create a list for all possible combinations, and then use the index of that list for a unique value to use in the raster. |

Is there a zonal statistics tool to calculate median and mode raster values for each polygon?raster, numpy, and R while indeed can do those operations are limited on the amount of ram your machine has.(meaning if your raster is more than you memory can handle, you program will crush). If your data are problematic in that kind of aspect, I recommend importing and using specialized GIS software, like grass |

How to find the maximum-area-rectangle inside a convex polygon? Your problem is a really interesting one, and I think I managed to find a solving algorithm here and here. |
