I am running GRASS 6.4.2 on a Macbook Pro OSX 10.6.8. I have updated all of the dependencies from kyngchaos' site, in the order that they are listed, and then installed the newest stable GRASS, after trashing the old version. My GRASSdata folder is in my home folder. I have a few locations, some of my data (vector), one of the Spearfish data, each has a PERMANENT folder within it. I was able to run through the first basic tutorial on the Spearfish data yesterday morning. When I tried it on my own data, I go to 'Add Vector map layer', in the GUI, it adds it, but the command console tab says "ERROR: Rendering Failed", with no information on why. It is now doing this on the Spearfish data, either vector or raster. In the Map Display, nothing shows up, but if I switch to digitize on vector data, I can see my sampling sites and stream network as separate layers. The data tables are there. This is data that has been exported from QGIS, all WGS84, as ESRI shapefiles, with the workspace extent set by the first imported layer. I'm sure it is something very simple that I am doing, but I can't figure it out. I can't help with the rendering problem, but as for distances along a line feature, I think that the v.distance option "upload=to_along" is what you're looking for. From the man page: to_along: distance between points/centroids in ’from’ map and the linear feature’s start point in ’to’ map, along this linear feature Any help is greatly appreciated. -- Micha Silver GIS Consultant, Arava Development Co. http://www.surfaces.co.il |
