Re: [GRASS-user] Apply a segmentation to derive objects
You are absolutely right :) My mistake. SMAP is a segmentation algorithm. But my idea was not to use SMAP as a classification but use a Segmentation process and only then a Supervides Classification.

But if i select rules and insert a path to a rules file I get this error: *ERROR: color, rules, and raster options are mutually exclusive* * * Was this suppose to happen? Yes. If you specify a file for rules, the color option should be blank. [color=rules exists for compatibility with previous versions, and only works from the command-line, not the GUI.] 2- About color tables with absolute values (e.g. NDVI) if a NDVI pixel has value between 2 defined values, which color does it get? It's interpolated. This is true whether the rules uses absolute values or percentages (or a mix of both). 3- About aspectcolr*.* To each category a color is assigned (e.g. white, yellow bla bla bla). Is there a list of possible colors to assign? The list of named colours is: white black red green blue yellow magenta cyan aqua grey gray orange brown purple violet indigo You can mix named colours and r:g:b notation freely. 4- Regarding assigning a rules.info to a map (as it's demonstrated in the same manual page). There are two ways. How come r.colors can use, as an input, rules.info if it's stated before the r.colors statement. cat rules.file | r.colors map=threecats color=rules color=rules reads rules from stdin, which in the above example is the contents of the rules.file via cat. The following commands will all achieve the same result: cat rules.file | r.colors map=threecats rules=- r.colors map=threecats color=rules rules.file r.colors map=threecats rules=- rules.file r.colors map=threecats rules=rules.file For reading from a file, the last one is preferable (and is the only one which will work from the GUI). Beyond that, using rules=- is preferred to color=rules (apart from anything else, rules=- works in 7.0 while color=rules doesn't; color=rules is only kept in 6.4 for backwards compatibility). The use of cat file | ... rather than ... file can be easier to read if you're creating a long pipeline in a script, as it places the source file at the far left of the command. The following both have the same effect: cat infile | cmd1 | cmd2 | ... | cmdN outfile cmd1 infile | cmd2 | ... | cmdN outfile but the former is probbably clearer. 5- One last question :) I tried to display the color table associated with a raster map layer (d.colortable) but I get the following message: Command 'd.colortable' not yet implemented Odd; you can try d.legend instead, or use r.mapcalc to create a test map to which you can assign the colour table. -- Glynn Clements gl...@gclements.plus.com ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Thanks in advance, Márcia PS: apologies for cross-posting I was just tinkering with R and I think this could be 4-5 lines of code using the sp package. It has 2 classes for GRIDs SpatialPixels and SpatialGrids. SpatialPixels is a point layer, derived from the centers of Grid cells and regularly spaced. You can convert the original layer to SpatialPixels then extrat the long from it's spatial data into it's table and then convert it back to a GRID for export. The basic process would seem to be to create a regular point grid of the center points of each pixel and then get the lat,lon for each of those points and join that back to the grid cells. It's possible in Grass, QGIS and others I think, not sure which would be easiest. Not sure where you were going with interpolation. Note: Since this is Global coverage, the points will not be regularly spaced numeric intervals due to projections, datum and the like, however it should look evenly spaced. I'm sure you could make them evenly spaced numerically if thats what you wanted. Alex ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
