Re: [GRASS-user] v.net.path problem(output seem to be airline distances instead of rout distances with multiple input points)
Stefan Neumeier wrote: Dear all, I am relatively new to GRASS so maybe I am just missing some important step in between. What I want to do is to calculate a simple distance matrix from x start points (polygon-raster centroids) to x end points (specific locations e.g. hospitals) based on a route network. In a first step I prepared the network so that every start- and end point lies on the network (via v.net, option connect). In a second step I created a point input textfile to use in v.net.path (ID startX startY endX endY) wit several thousand records. Testing the shortest path calculation for one, two or three coordinate pairs read in from the point input file works as one would expect and I get a new vector layer depicting the pathes from the start points to the end-points based on the road network. But if the number of points in the input point file exceeds 4 coordinate pairs GRASS calculates all consecutive distances seemingly as airline distances instead of road based distances (In the output vector layer the pairs of points are connected with a straight line only).

[GRASS-user] Addapting i.gensig GRASS to perform outlier detection
Greetings Mr. Neteler I'm implementing a methodology in GRASS to eliminate training_areas outliers. What I do? 1- first I pick up the current training areas for a class and I calculate mean vector and covariance matrix 2- Invert the covariance matrix 3- Compare each pixel, that is included in a training_area, with a defined threshold and if it's OK, It's still labeled as 1 or, otherwise, it's eliminated. It would be pointless in developing this function from scratch in GRASS so I used i.gensig that is used to calculate mean vector and covariance matrix for training areas. (This means that step 1 and 2 (by a simple implementation) is covered. (Do anyone suggest other function instead of this?) My problem is with the third step (I'm still not very familiar with some GRASS programming functions/functionalities) I have created a cycle that goes for each row and col and I get the correct raster pixel value from group but I'm not being able to retrieve the classification. This is an overview of the approach: for row=0, rownrows, row++ for col=0, colncols, cols++ Check in training area if the pixel value is -1 (this is the problem I'm not being able to get thiS) for band=0, pbandnbands, pband++ pband[band]=cell_value for band band, in row=row, col=col and that is included in the training area. - Then apply the compare (easy) - write (I think it's not a problem) } } } In what am I a bit lost: 1- How can I get the value from training areas raster? 2- How can I only apply this rule only to the pixels that are included in a training_area? Can anyone give me a few tips? Thanks Katrin ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

The commands performed would be something like this: v.to.rast input=building_vector output=build_raster r.mask build_raster r.mapcalc clipped_sat = satellite_image r.mask -r @ Grass List.

Re: [GRASS-user] r.sun command
Pascal: in the command r.sun, the latin raster must be in WGS84 ? probably, but my best advice is: don't use latin=. Run r.sun from a non-simply XY location instead. Even if it was in the current location's ellipsoid instead of WGS84, the difference (maybe ~100m) wouldn't really affect the position of the sun in the sky much. if you have a reason to run from a ungeoreferenced location, I'd be keen to hear it. I never remember if I've already removed that option from trunk, but I mean to. The overhead of reading the map is more or at least equal to the time saved by doing the reprojection calc, and keeping it just confuses things for the user and programmer alike.

Try deleting the old GRASS application before installing your GRASS compiled from source. Actually, I've had to download and reinstall your binaries just to get a working version going again - so I'm not inclined to risk losing my production setup. Can I give the current 6.4.0 a different name or does it have to be completely gone? I may well put this project on hold for a while. You can rename the existing GRASS, say GRASS-6.4.0.app. Once you compile and install 6.4.1 (as GRASS-6.4.app), if you use Qgis it should continue to work using the new GRASS. - William Kyngesburye kyngchaos*at*kyngchaos*dot*com http://www.kyngchaos.com/ The equator is so long, it could encircle the earth completely once. ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
Re: [GRASS-user] Difference between r.series; r.patch
katrin wrote: I have a sequence of satellite images (e.g 1 in the north, other in the center and other in south) that I want to merge in a single image. I found three GRASS methodologies: - r.series - r.patch - i.image.mosaic. Which one is the best to perform what I need? Hamish: I'm not really familiar with i.image.mosaic, but r.patch would be the one to use if you have three satellite images taken in sequence which you wish to merge into a single image. r.series is usually used to merge overlapping maps, r.patch to merge adjoining maps. to make r.patch easier, you can do: g.region rast=map1,map2,map3 to extend the region settings to the outer bounds of all three maps. Something critical, if I am not wrong: the order of map1,map2,map3 is important (when patching overlaping maps). Check the r.patch manual.

Re: [GRASS-user] GRASSsvn release branch g.region broken
[...] Markus M: The safest order I figured out experimentally is make distclean svn up configure make make install - make install requires sudo under Ubuntu. - a reminder that the last step (sudo make install) can be avoided completely and grass sessions can be launched directly from within the /geo/osgeo/src/grass64_release/bin.x86_64-unknown-linux-gnu/ directory. e.g., I use the following link: /usr/local/bin/grass64 - /geo/osgeo/src/grass64_release/bin.x86_64-unknown- linux-gnu/grass64 Also, in case one wants to install the compiled binaries, the program checkinstall is a good option instead of make install. It creates a .deb package and installs it which can be easily uninstalled of course.

Re: [GRASS-user] Changing raster boundaries
Christian: Hi GRASS users, how to change the boundaries of a raster map (simply expand the border) without any automatic modification of map resolution as it will happen when using r.region map=.. n= ..s=.. w= e=.. ? Thanks for some hint. Micha: How about changing the current region with g.region, then use r.mapcalc to create a copy of the original at the new extents? A reminder that r.region might be useful as well in this case. Kind regards, Nikos ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Hamish: in the GloVis preview I only see a few clouds in the NE corner for that date. (Sept 14, 1988) Right. I specifically selected a scene with a few visible clouds. Isn't this a good quality test for the module (instead of using an easy scene full with clouds)? Maybe 1991/10/25 is another good scene for a cloud test? (looks like 20% high cumulus with shadows) Yep, why not. Will order. Note the % cloud cover in the GloVis previewer is (AFAIU) using the same ACCA algorithm as i.landsat.acca, so the result should be similar. (??) hmmm... have to check. For the Sept 14, 1998 example the GloVis info says 0% cloud cover, but maybe that data is old and the latest ACCA says something else? # rgb colors for 742 i.landsat.rgb r=lsat5_1988.2 g=lsat5_1988.4 b=lsat5_1988.7 strength=96 d.rgb r=lsat5_1988.2 g=lsat5_1988.4 b=lsat5_1988.7 # obvious clouds maybe i.landsat.dehaze is worth trying before i.landsat.rgb? # toar i.landsat.toar band_prefix=lsat5_1988 method=uncorrected \ sensor=5 product_date=1988-09-14 date=1988-09-14 \ solar_elevation=48.6773844 do not assume production date is the same as acq. date; check metadata values against values in the source code. For the Mar 31, 2000 sample data it made a difference. ok! # acca i.landsat.acca -5f2 band_prefix=lsat5_1988.toar \ output=lsat5_1988.toar.acca # how many cats? r.info lsat5_1988.toar.acca -r min=6 max=9 see r.category, r.stats -c, or d.legend for meaning of category numbers. (6=cold cloud, 9=warm cloud, 2=shadow) i.landsat.acca is in flux today, best to wait a few days .. (some earlier improvements just got clobbered and new ones introduced, so I'm unsure of where we are now) In the acca result: - clouds are detected (cat=6), not that bad(ly) I suppose. Some filtering could push away the (rest of the) noise. the cloud despeckle filter can remove some lone non-cloud cells which are surrounded by cloud. after that I guess it's r.neighbors or r.mfilter. --%- - obvious mis-detections (commission errors) found within - n=188310 s=168270 w=618870 e=636150 (bare ground? urban area? not sure about the confusing land cover/class here...) - n=219030 s=180510 w=646410 e=655740 (road) ? maybe google maps satellite view helps if the landsat is too coarse to ID features. - in the borders due to the non-identical extent of all bands (!?) I've seen something similar, maybe r.series to accumulate NULLs in all input bands and use that as a MASK? - categories 7 and 8 seem to be empty, category 9 looks very messy cat 7,8 are undefined, cat 9 probably has more false positives in warm land, cat 6 (cold cloud) probably has more problems in snowy areas. Could it be that non-cloudy acquisitions are mistreated by the algorithm? The paper by Irish listed in the i.landsat.acca man page is worth reading, it explains a lot and points out where the algorithm does not do well. I can't clearly recognise clouds in the landsat scenes included in NC data set (both the 1987 and the 2000 scenes). I'd guess that they were specifically chosen to avoid days with obscuring clouds. Will (then) the algorithm work (only) with (very) cloudy data? One thing the paper mentions, and I've observed, is that it does not do well with thin wispy cirrus clouds. Apparently MODIS does a bit better there because it has a detector in the needed 2um range to pick those up, while the Landsat only has 11um which misses those cloud tops. (IIRC) --%- Will check the above at some point. fyi, I've just added what we know about the NC 2008 dataset Landsat images to the grass wiki: http://grass.osgeo.org/wiki/LANDSAT#Sample_data Thanks, Nikos I'm downloading them now.. I expect they'll be reprocessed versus the metadata calibration values shipped with the dataset. (??)
