I have a enterprise geodatabase with 36 feature classes. What I want is a tool, script or model that will save a copy of any open feature class in another geodatabase. I want this as a tool that can be run by my end user and I don't want them to have to enter where the feature class copy...

I am reading values from large rasters in geotiff format. The size is around 30GB and there is only one band. I'm using geotools to do that. I did some experiments on reading the whole raster to find the best way to do this and realized that performance varies greatly. This is code I used: file...

I have mysql table with shape column that stores the latitude and longitude, I need to write a sql query that transposes latitude as longitude and vice versa.I couldn't find any easy to get this using query. Any help is appreciated. أكثر...

I am trying to find, or get help creating, an SLD to render dot density symbolization for a polygon shapefile for an online GIS display - in this case WorldMap. The dataset is county level US Census of Agriculture data for cotton production in 1860 (tables and shapefiles from NHGIS). I am able...

I want to calculate a route consisting of 4 points with a script tool and save the results to disk. I need the route to appear as layer on ArcCatalog for continuing working with it (modification of its attribute table).The script tool completes successfully but no output is saved.So, I tried to...

I am trying to make a spatial join to calculate the mean value of many variables (100+ columns) of census tracts by city. In order to do that, I would, in QGIS Desktop, run a spatial join (join attributes by location). I did it and it worked. However, I need to automate the process and use the...

Just a short post to say two of our PhD students, David Masad and Jackie Kazil have been developing an agent-based modeling framework in Python called Mesa. To quote from David's talk abstract: "Agent-based modeling is currently a hole in in Python’s robust and growing scientific ecosystem...

In 2010, Haiti was struck by a magnitude 7.0 earthquake that killed between 220,000-316,000 and caused tremendous damage to homes and businesses on the island, making it the most deadly natural disaster in the last decade. In the immediate aftermath of the earthquake, Haiti's communication...

During the relief efforts of Katrina in 2005, response teams in low lying New Orleans relied on geospatial data to predict the most inundated parts of the city. Lidar, which was the geospatial technology used to attain the inundation data, is a high-resolution, high-accuracy elevation data...
