Andreas, You're running 64bit SAGA, right? (if not sure, click the question mark on the menu bar, and click About - should be towards the top). I actually like SAGA because I can throw pretty giant files at it. Just to test out and make sure, I just loaded in a 10GB GeoTIFF with integer values,

[Qgis-user] Exporting Fine-Scale Map with Open Layers Imagery

2014-11-16 Thread Michael Treglia
Hi All, I was trying to export a fine-scale map (total extent ~75m x 75m) that had Google Satellite layer from the OpenLayers plugin. It took a bit to render in the map viewer and print composer, but wasn't unreasonable. However... At that resolution, I haven't been able to export the map from

Hi Juan, To display a PostGIS Raster in QGIS, I think you need to use the Database Manager plugin (DB Manager). If you have it installed/activated, you would access it from the Database tab in the menu bar at top. (I'm on QGIS 2.6 and 2.4, but I'd imagine its the same for 2.0). Is that what

Hi Massimiliano, Regarding the Home Range Plugin, on Windows it looks like you need QGIS 1.7.3, and possibly an earlier version of R. I haven't tried, but I would suspect that as long as you install the old (deprecated) adehabitat package in R, it might work with a newer version of R. I found

Just to clarify, the goal is to to effectively map the ridges and furrows? Or am I missing something? If there's high resolution orthoimagery, you could try to use standard image classification techniques to classify the ridges and furrows. They're visible enough on Google Earth that I bet it's

Re: [Qgis-user] Tranferring data

Hi Marilena, In my experience it seems that if the source data (i.e., original shapefiles and such) are kept in the same folder location relative to the .qgs file, the .qgs files should open fine. If you can't do that for some reason, I don't know what to do, but that might be useful to learn.

Manuel, Is it giving you any specific error? Or just not run? Or is it freezing up QGIS? One thing to try is to make sure it is looking to the appropriate folder for GRASS - especially if you changed versions of QGIS and GRASS in your latest OSGEO4W update. To do that: 1) Go to the Processing
