Re: [gdal-dev] Errors in geotransform computation from ENVI rotated header?

Greetings, Kevin makes a well-reasoned argument that my initial patch was not general enough. It is true that in my application the x,y pixel sizes were equal so I did not detect the bug. I am a geospatial novice and I derived my formulae from a response to a question I posted on the GIS Stack

Hi, I think my issue is not strictly related. The problem I had was about the way the rotation angle is computed in WriteProjectionInfo() when the determinant of the geotransform is positive. Let's call det(GT) the determinant of the 2x2 sub-matrix of GT, without origin terms.

[gdal-dev] Compute raster from other rasters using a Bayesian Network

2017-07-19 Thread Ari Jolma
Hi, Just a brief note that I'm working on an extension to GDAL, which allows one to compute a raster from other rasters using a Bayesian Network - cell by cell. To see why would one do that, see for example https://www.researchgate.net/publication/240682865_Bayesian_Network_Integration_with_G
