Re: [OSGeo-Discuss] offline maps
These are generally available but what I would like to get my hands on are the landsat 7 swaths that are also freely available but are very hard to come by in download terms. My sense is that there are quite a lot of Landsat 7 data available for free download. Scenes, though, not swaths.

[OSGeo-Discuss] clip raster by a circle in map coordinates
I need to clip an input raster data set by a circle and write the extracted cells to a new raster. Then I have to repeat 35,387 times, so any solution needs to be scriptable. The dream solution would be to issue a command with arguments specifying the X coordinate, Y coordinate, and radius. I assume, however, that I'll need to do some sort of intersect operation using either a mask matrix, a rasterized vector circle, or some XML that defines the circle. Is this possible? Any script/software recommendations? I started looking in to GRASS r.circle but haven't yet gotten very far. Basically, I want to do what the ArcGIS Extract by Circle tool will do, but I want to do it much more quickly and without ESRI.
