Re: [GRASS-user] RST - how does it chooses from near points?
I cant answer the question of how the v.surf.rst module choses points, but I can say that with the use of r.in.xyz you can control this quite well. For example, (and relating to the last question) you can use different methods to assign values to the cells from ASCII import. Meaning if you have multiple points in a cell, and you only want the values that are the minimum in the cell, use the 'method=min' option. Alternatively, you can use 'mean' and 'max' for other applications as well. then you would r.to.vect the data, as 3d points and then interpolate with v.surf.rst. If I recall right, by doing this r.in.xyz, it cut out about 35% of the processing time for v.surf.rst in my application. Especially for LiDAR data, I found the r.in.xyz module to be nothing short of spectacular. With the 'method=n' option, and an r.report raster unit=p, you can see the percent distribution of points per cell to help set cell size. These are some great tools!

If I were to use a single location, but with different mapsets, would there be issues with changing the region boundary and/or the cell resolution? not at all, all mapsets are independent. For example, in my main area of interest (basin) there were areas I needed to do finer detailed analysis, going from 25 foot cells to 3 foot cells (r.in.xyz + r.report helped me find this optimal cell size, great stuff!), would this be an issue within the same location, but using a different mapset?

If you do it serially, no problem. Otherwise it will conflict. Under this scenario, does it still make sense to use a single shared location? Most likely. One problem I foresee is with vectors using a single sqlite.db file, That's true. You cannot write simultaneously to the same sqlite.db file. http://en.wikipedia.org/wiki/SQLite A write access can only be satisfied if no other accesses are currently being serviced, otherwise the write access fails with an error code (or can automatically be retried until a configurable timeout expires). This concurrent access situation would change when dealing with temporary tables. But just use different names, so multiple sqlite.db files? in two different locations and then getting the vector database out of sync, and unable to rectify this with syncing the locations. It seems that reprojecting the data into the location is one way to deal with this single DB issue. I feel that it's making things worse. Most all of what I'm doing is time-consuming raster analysis though, and on the first sync, things seemed to work as expected. OK fine. Please let's collect ideas in the wiki how to deal with vector data and related DBs when processing in parallel.

I am not totally certain about that. If not it would be nice to have. By using a single file for the entire mapset's DB needs you much more quickly reach 2gb file sizes, make it less flexible for backups, have longer seek times, more chance for a single bit of data corruption to cascade etc. I don't know which way is better, for now I hope we can have both ways and race them against each other to see which one wins. I'll even press the issue. I just made SQLite the default DB in grass7/trunk. (using a single sqlite.db file per mapset) We'll see what happens..

You probably need to enable 'snapping' within the v.digit module to make the polygon vertices coincident. See the attached screenshot showing where to set this on the v.digit Settings. Once you have snapping enabled, you may still have to manually move vertices that were digitzed prior to enabling snapping. Use the 'Move point, line, boundary, or centroid' tool on the v.digit interface (see attached screenshot). Once you move a vertex on top of another with this tool, the two should snap an become coincident.

Re: [GRASS-user] again help
GRASS is not ArcGIS. So it doesn't have the same restrictions that ArcGIS does about points, lines, and polygons being in separate layers. Of course, YOU can make a vector file (i.e., layer) that is only points or lines or polygons, but you are not REQUIRED to do so. If you want to export vector objects from GRASS to shapefiles or something else, you can select only one feature type to export. GRASS also allows you to convert between vector types and converts from raster to vector. Why is this a problem? I always was annoyed about the requirement of ArcView and ArcGIS to have only one feature type per shapefile.

Re: [GRASS-user] Extracting the external boundary of a vector file
Edward Tomlinson: I have a whole bunch of data from an RTK GPS. File exists as a MapInfo file. Imports into grass fine with area and centroids. My problem is however, i want to create another vector file that contains the mask or the external (an internal island) boundary. I have been able to create the external boundary fine through the following. v.category (delete categories) v.category (add category as 1 for all) v.dissolve (combine all boundaries with common category) This is great and works fine for the external boundary. However there is meant to be an island in there. Somewhere along the way (i think after the second call to v.category) it fills that island in. right. Has anyone got any hints or ideas? Essentially i am trying to create this vector to generate a mask for further interpolation of the point heights. I am assuming that i need this island removed (as there is no point data for it) otherwise it is going to effect the interpolation. Use v.overlay for the new and original map, operator=not, etc. or other combination of operator=and etc until you get what you want. another trick is v.extract list=1- to only extract features with a cat number. (then v.overlay) v.hull is another module to look at for this instead of v.dissolve. Hamish ___ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user

Re: [GRASS-user] Triangles polygons with Arc*
Just curious if anybody encountered this issue with Arc*: it's a common problem. It does seem to be. short answer: TINs stink. Raster maps created from TINs stink more. My colleague used SRTM DEM converted to grid format of Arc He mentioned that it is fairly common when you convert raster grids in arc to vectors (shapefiles). Especially with very small areas like a 2-3 pixels. Will look into this further. To all the others who gave me a list of Arc mailing list thanks!

Re: [GRASS-user] newbie: processing lidar with r.in.xyz
andrew haywood wrote: i am currently enjoying the flexibility of using r.in.xyz to process lidar data over native forests in Victoria, Australia. Thank you hamish for such a great tool. cheers, it is always nice to hear what it is used for. At this stage I have 'binned' my data into 20m cells and calculated a number of metrics (including 13 vegetation height percentiles p5 p10 p20 .. p90, p95, p99) based on the z values. What I was wondering is how can I calculate the mean intensity for the associated height percentiles. Just pass the intensity as the z= column instead of the height column? That is why I called it Column number of data values in input file instead of elevation values. It doesn't know/care what the data means. To get around this I have written a script in a proprietary stats package to create the intensity metrics. However, I would prefer to use Grass and opensource tools to do this binning what sort of metrics are you after? Any suggestions would be appreciated My data is in the following format x|y|ground|intensity|class|canopy_top|height 410774.45|5820999.93|773.3|23|10|766.0983886719|7.20161 410763.07|5820999.9|802.27|2|10|763.9434814453|38.3265 410765.47|5820999.94|773.11|90|10|764.2877807617|8.8 410758.09|5820999.95|807.99|47|10|762.8372192383|45.1528 410748.12|5820999.93|760.89|8|10|760.5731811523|0.316819 ... I suspect I should start to learn python. time well spent regardless; good return on investment if you like to think like that. a nice place to start: 10 minutes Python tutorial for programmers of other languages http://www.poromenos.org/tutorials/python you could probably do what you want quite simply in awk as well, but I'd only really suggest that if you know UNIX or C already.
