Re: [GRASS-user] grass70 start problems
Manuel, all, GRASS 7 development has finally really started: http://lists.osgeo.org/pipermail/grass-dev/2008-August/039264.html GRASS 7 will be unusable for a while, better to switch to 6.4 if you want to remain productive.

I have digitised some points, roads and a lake in GRASS and would like to be able to upload them onto my Garmin Etrex Legend.

RE: [GRASS-user] Multiple errors after lengthy absence from Grass 7
As Martin says, GRASS 7 development has now started. The first phase of development is to eliminate deprecated functionality. This will break stuff. Eventually we should get around to replacing most of the stuff which breaks with more usable alternatives. In the meantime, use 6.4 if you just want a working version. Great, thanks for the update.

I see some room for confusion here. I think on Garmins the basemaps built-in maps are not vector format but raster format .img files. So the short answer is you can't dump them on the way you're trying to, you need to convert them. You'll need to look for a tool like this http://wiki.openstreetmap.org/index.php/Mkgmap but meant to work with the formats your using and the platform you're on. Hope that helps, Alex John C.

Re: [GRASS-user] Re: Thin plate spline for climate point record interpollation?
I'd be keen to see something like this too, if time permits I might even work on it myself (if I convince my colleagues it's worthwhile for our project). J On Sun, Jul 27, 2008 at 2:30 AM, Andreas Philipp [EMAIL PROTECTED] wrote: I think Dimos does not look just for normal interpolation of a variable just using the spatial information of the variable itself, but for a procedure using additionally a multiple regression scheme of a set of independent variables. As far as I know there is no tool yet to do that easily within GRASS at the moment (please correct me if it is there already). Because I was also thinking how to realise a regression based interpolation scheme in GRASS and might be not the only one, I try to describe the problem: Those independent variables can be elevation, lat and lon of the station or relief parameters which have a stable average influence on the spatial distribution of the target variable. E.g. in order to interpolate temperature accurately you calculate a regression coefficient from height-above-sea-level-values onto the temperature-values (over the whole space and time domain). Then you subtract the fitted temperature values from the observed temperatures and receive a temperature anomaly field (the residuals) which would be realised if no height differences would be given but only the spatial temperature variation due to meteorological reasons. Then these anomalies (residuals) are interpolated in space with splines or whatever onto a regular grid. Afterwards this grid is scaled to height again by using the regression coefficients, et voila. This takes into account that the target variable is not only dependend of spatial autocorrelation (interpolated temperature of a mountain is then not as high as the station record in the nearby valley). This is a procedure which is commonly recommended in climatology. However, in order to calculate the regression coefficients, longer time series should be used (not only the time slice or map which is intended to be interpolated) in order to get the pure average dependence of temperature to elevation. Further it might be necessary to do the whole analysis for each month of the year separately in order to account for effects of large scale climatological differences in the annual cycle. Instead of elevation only also latitude, longitude and other parameters can be used in a multiple regression scheme. An especially interesting independent parameter is a typical relief type of the surrounding of each gridpoint (achieved by principal component analysis of the neighbour grid point heights in a moving window. May be to be plugged in into r.li?). If I'm right this is not easy to do within GRASS at this time. May be R can be used as a work around? Anyone has an idea? I think it would be great to have such a tool originally in GRASS (I'm sure a lot of climatologists would grep for GRASS just for that feature) but it is a bit of work to program it (I think the main problem would be the multiple regression, if only there was a fortran90 interface ...). However to use a single independent variable may be r.mapcalc could be used if the vector point observations are transformed to raster maps (bivariate regression is rather simple even if quite a few raster maps are neccessary). Hm, quite a long mail, but may be some others are interested and willing to solve ... Please correct me if I'm missing something.

These tools will let you create maps for your Garmin GPS from various vector data (with a lot of work). See: http://home.cinci.rr.com/creek/garmin.htm for a walk through the process and links to the tools. Since you've already imported your GPX files from gpsbabel into GRASS, you can just export them as shapefiles for reading into GPSMapEdit. GPSMapEdit will read shapefiles, but it's a bit of a chore to get it Just Right.There is talk about making an OGR output format that can handle the Polish format used by cgpsmapper, but it ain't there yet.

I read a post on the GRASS mailing list archive that mentioned cGPSmapper, but it seems like this only works with ESRI shape files (v.out.ogr again) if you have one of the paid-for versions. Is there any open source software that can do this? Can GRASS export in a format that can be more easily converted to be compatible with the GPS? -- Tom RussoKM5VY SAR502 DM64ux http://www.swcp.com/~russo/ Tijeras, NM QRPL#1592 K2#398 SOC#236 AHTB#1 http://kevan.org/brain.cgi?DDTNM Argue for your limitations and sure enough, they're yours. -- R.
