Sneak Peak QGIS 2.6
By Lurker,
Independent Grid (Print Composer)
Grids in the print composer can now be added independent of the projection of the map, and you can add as many grids you could possibly want.
Colour Picker
The standard colours can be edited in the settings ( Settings – Options ). Not only can you add and remove colours, you can also name them to your content. Your personal standard colours can then be shared by import/export functions (GIMP Palette *.gpl).

Select stream network within a fixed distance from a point
By weeberm,
Is there a tool out there that would allow me to select a portion of stream network that is within a fixed distance from a specific point on that network? I want to be able to select all portions of my stream network that are within 4 "steam miles" (not euclidean distance) of that point, both upstream and downsteam. So far I've manually selected the portions of stream within 4 miles, but it is time consumning and cumbersome. Is there a tool to automate this process, as I have upward of 40 differ
New global marine gravity model from CryoSat-2 and Jason-1 reveals buried tectonic structure
By Lurker,
Gravity models are powerful tools for mapping tectonic structures, especially in the deep ocean basins where the topography remains unmapped by ships or is buried by thicksediment. We combined new radar altimeter measurements from satellites CryoSat-2 and Jason-1 with existing data to construct a global marine gravity model that is two times more accurate than previous models. We found an extinct spreading ridge in the Gulf of Mexico, a major propagating rift in the South Atlantic Ocean, abyssal
looking for someone to provide advice on topo GPS map project
By RCinSTP,
I have some digital map data and I would like to create a topographic map for GPS handheld. I am looking for someone I can email, skype or phone to ask a lot of general questions. I can pay for your time. I have a set of hundreds of .jpg image files from an online topo map. The .jpgs are 256x256 pixels and the names relate to the x, y coordinates on the map. The image tiles are not geo-referenced. I also have some .gdb files that I can't seem to open with GIS software. I am in the Minneap
Determing the south west grid grid cell of topo srtm data
By winash12,
Hello,
GIS newbie here. Please feel free to bump my question into the right sub forum if it does not fit in here. If I choose Eurasia as my grid from here - http://dds.cr.usgs.gov/srtm/version2_1/Documentation/Continent_def.gif how to determine the grid cell that represents the south west direction i.e. south of the southern most point AND west of the western most point. Is this done by human inspection(trial and error) or some algorithm there than do it ?
