This code was working a couple weeks ago, then without changing anything, it started throwing an error. Here's the code: #Query climate table sFrom = dateIncrement.strftime("%Y-%m-%d %H:%M:%S") sTimeStamp = dateIncrement.strftime("%Y%m%d_%H") dateToTemp = dateIncrement + delta...

I'm creating a PostGIS database which will hold thousands of different shapes (imported from Shapefile, GeoJSON, etc), and they'll stay there and be queried over time. Do I need to create a different table for each file that's imported? It seems a bit weird that each "file" should have it's...

I am troubleshooting a slow st_geometry query in Postgres 9.2 that uses ST_Intersects--a basic Select from table where ST_Intersects type query. table_extent |...

Bonjour, Je cherche un moyen de comparer géométriquement 2 rasters. En l'occurence, j'ai des images IRC d'une zone et la BD Ortho et je cherche un moyen automatique de les comparer et de relever les écarts de géométrie entre les 2. J'ai vu que la comparaison de raster était possible sur...

By Emily Watson, FracTracker Summer Intern Sea otters, an endangered keystone species, are at risk due to offshore oil and gas drilling spills. Along the west coast of the U.S., this marine mammal’s habitat is commonly near offshore drilling sites, specifically in California and Alaska. Sea...

I'm looking for an algorithm to calculate the 3d bounding box of a spherical polygon - i.e. the min/max X, Y and Z over that part of the surface of a unit sphere. The purpose is to aid fast area-overlap calculations for large numbers of simple (convex) spherical polygons :Having all the...

the attached are my tool and its parameters. I am able to run the tool in my PC but, when I transfer to another PC its giving me an error that can not create output feature layer from projection part.I checked relative path store box, but still getting the error.I need to know why I am getting...

Hi GIS Stack Exchange, I have had trouble getting the MbTiles plugin to work with GeoServer. I installed each of GeoServer 2.5, 2.6 and 2.7 in turn. All three installations seemed to work fine on localhost without any plugins installed. Next, in all three cases, I carefully located the matching...

I've classified an elevation raster into 4 classes. Is there a way to export these class values (0, 1, 2, 3) to a separate raster? I've tried exporting the raster to file, but this just gives the same elevation values. In other words, I want to replace the pixel values in my DEM with their...

On my webpage where I am displaying my maps, I want to add a link to the metadata of the selected map. I have specified the link in GeoServer in the MetaDataURL field, and should be able to retrieve it with a GET request and finding it in the XML(See below for XML and Jquery code)But every time...

I'm trying to do some simple things with the .net framework and ArcObjects, but have little experience with this type of development. I would like to iterate through the layers in a map document and change the transparency of the raster layers who's names begin with the letter "g". Here is...

I have a Geodatabase containing many feature datasets storing contaminated site information. Each feature dataset contains a polygon named 'SITE' followed by the unique site ID (for example 'SITE_9345'). What I would like to do is merge all the 'sites' into a single shapefile or feature class...
