Whenever I encounter an aggregation problem like this, my inclination is to move to the realm of the database. In this case, you can take advantage of Spatialite with its full SQL support to get what you want. In order to try out the process, I downloaded a

Hi all. The next hackfest is approaching, and it is a pleasure seeing that the flow of small donations by happy users is increasing. This is much appreciated, as it is allowing us to support the participation of a number of developers, paving the way for yet another successful meeting. It is

[Qgis-user] GDAL : extracting a part of a raster

Hi, I tried to cut a part of a raster (from ASTER G-DEM) in GeoTiff format, to get a DEM fitting my project. I tried to cut this raster by different means, i.e : - setting the coordinates of the area of interest - I get Computed -srcwin falls outside raster size of 4000x4000., - using a layer

[Qgis-user] EPSG 4326 Vs EPSG 900913

2012-03-27 Thread Giacomo Fontanelli
Hi boys (and girls of course) maybe this is a stupid question: could you explain me the risks that occur when i put the gps points (generally WGS84 = EPSG 4326) in google earth (EPSG 900913). I know that google has a particular method to manage the projections of its optical satellite image and

Google Earth uses EPSG:4326. Google Maps uses Mercator (was EPSG:900913, now is EPSG:3857). KML/KMZ only supports EPSG:4326 so you should have no issues. - Jamie On Tue, Mar 27, 2012 at 9:19 AM, Giacomo Fontanelli giacomofontanell...@gmail.com wrote: Hi boys (and girls of course) maybe

[Qgis-user] Using CRS to convert from Lat Long to Irish National Grid

Hi Folks, I'm in a bit of a pickle. I am preparing some maps for a grant proposal and wanted to add some good vector maps for lakes and oceans. The problem is these vector maps are in latitude/longitude and I need to convert them to Irish National Grid. I tried using v.proj in GRASS but ran

Hi Kurt, Unfortunately, I think you may have misinterpreted what 'on the fly projection' and 'set layer CRS' are for. Your layer's CRS should be set to whatever the coordinates are actually measured in, and if your layers are indeed in lat/long (probably WGS84), then this should stay that way. If

Hi Carson, Interesting. I switched to TM75. Then I imported the lakes and ocean from the shape files and they just snapped in place. I was trying to do it from GRASS. When I tried to set them to the rest of the GIS they vanished until I returned them to their original CRS. That was almost

I think we do ok in this area. We now have a Facebook, Google+, and Twitter page, there is email and IRC, which are old school but work well for that reason. We also have a large share of information on gis.stackexchange.com. After the hackfest there should be new methods to help build a better
