Re: [gdal-dev] gdal python script to calculate categories statistic

Hi Giuseppe, gdal_calc is built on operations with matrices using the Python module 'numpy' http://numpy.scipy.org/ Instead of digging into it I would suggest to study numpy functionality a bit. The following simple script somewhat solves your problem: import numpy as np """ you may data f

Hi, I'm relaunching the following thread: http://lists.osgeo.org/pipermail/gdal-dev/2011-June/029034.html This time with GDAL 1.9 and the problem remains. Further explanation of what I'm trying to achieve: I would like to write and read 3d spatial data. I have a 3d point(-1092.7172471465196 122

RE: [gdal-dev] Layer operations, a proposal

As I have mentioned previously (http://lists.osgeo.org/pipermail/gdal-dev/2010-January/023089.html) I think something like this would be a great addition to OGR. No doubt it would be a huge job--basically turning OGR into a GIS--but if it could be done well, with sufficient performance and in the c

Ari, I think this would be an interesting addition. Would you be willing to write up an RFC? I think the layer creation step should be a different call than the feature processing step to maximize the chance that folks who need to do something very format specific at layer creation can do so an

[gdal-dev] gdal_translate crash on certain filenames

Hi List, We have encountered something really strange in our GDAL build (1.9.0, built from source on Windows 7 64-bit). It appears that "gdal_translate" crashes (i.e. Windows popup dialog that says "gdal_translate has stopped working...") when the output filename starts with certain strings.

[gdal-dev] Layer operations, a proposal

Folks, I propose a set of new methods for OGR layers (see the PDF). I took the basic ideas from page http://courses.washington.edu/gis250/lessons/Model_Builder/ which seems rather comprehensive. I wrote the pseudo code myself quickly (thus it may not be optimal and may contain bugs - improvem
