Imagery Library/Modules in GRASS 7

Library

​Imagery Library from Programmer's Manual

• Imagery Library needs fundamental clean up (the library is not maintained from GRASS 5)
• Improve Doxygen documentation
• Reimplement groups to be generic element (in GIS Library)
• Merge grass/trunk/lib/imagery (i.* except for i.points3, i.rectify3) and grass/trunk/imagery/i.ortho.photo/lib/ (i.ortho.photo, photo.*)
• grass/trunk/lib/image3/ never finished improvement which integrated Imagery Library and Orthophoto Library. Seems to provide also ortho rectification for satellite data (i.points3, i.rectify3)

Modules

• Merge of i.points, i.vpoints, i.points3 - drop these altogether? (loss of interactive XDRIVER)
• Merge of i.rectify and i.rectify3 - maybe depend on gdalwarp C API for this?
• Addition of new resampling algorithms such as bilinear, cubic convolution (take from r.proj?)
• Add other warping methods (maybe thin splines from GDAL?)
• Implement/finish linewise ortho-rectification of satellite data
• ~Depreciate tape functions in next major revision of GRASS~ and create a tape module that accomplishes tape access. - still desired? MN 10/2008
