Replying to [comment:21 cmbarton]: > > It is easy for the GUI to create a spin box for layer selection that runs from -1 to a max. But that would be the case for all interfaces that use layers. What happens with d.vect layer=-1? > In grass7, nearly all modules have a layer option because of direct OGR read access added by Martin. Layer=-1 means, use all layers, as for d.vect. For most modules, the layer option is optional, i.e. it must be possible in the GUI to either leave it empty or specify a layer if necessary. > The problem is using the layer selection to make the module do something that has nothing to do with layer selection. For ease of parsing in scripts and for consistent creation of a GUI interface, each distinct function should have it's own argument (option or flag). Trying to combine two different functions into one argument leads to problems in using the module syntax for anything beyond human command-line use. I agree, there should be a possibility to choose where the z values are coming from. > > I guess I don't see what the problem is in having a z flag. > Added in trunk r41098, please test. Works for me in nc_spm_08 with both precip_30ynorm...@permanent and precip_30ynormals...@permanent. When using z coordinates of precip_30ynormals...@permanent, be aware that these are elevation, not precipitation. If it passes your testing, backport to all grass6 branches? -- Ticket URL: <http://trac.osgeo.org/grass/ticket/96#comment:23> GRASS GIS <http://grass.osgeo.org>
