Hi I am new to QGIS and want to replicate the way Arcmap displays values using an HSV colour ramp. Arcmap seems to assign colours repeating the colour ramp many times throughout the entire list of values Whereas QGIS assigns colours from beginning to end using the entire colour ramp The...

I work with ArcMap 10.1. There is a proposed area for building a dam. I'm just trying to calculate the approximate volume of dam in different elevations. I created a raster of area and also other several rasters with different fixed elevations (50, 75,100 ...) and tried to calculate cut and...

Data: Zipped ea.ml1 shapefile can be found here, and the country outline can be downloaded here at the GADM site. I've been using the Ethiopia ESRI shapefile. Branch locations are here. Per the suggestion of user cengel, I have started converting a map project of mine to ggplot2. Data is listed...

I have created a map on tilemill and can export the tiles to mbtiles. However I need to determine the resolution for each zoom level. On a previous project that used different technology (tilecache) I could call the following URL and it would return the resolutions...

I have a table with coordinates that are undefined, but I know they could be in several different state plane zones/datums. I am thinking I can possibly use coordinate ranges to assign the coordinate system to each record. The state plane zones are based on county boundaries, and so I created...

I'm trying to manually edgematch some adjacent polygons. When I try to add a vertex to snap it to another vertex on an adjacent polygon, it invariably undoes itself, as shown in this video that I made demonstrating the problem (I couldn't figure out any way to post it here since it is not an...

I have a complex portal site with 20 layers around the US. I also have the default geocoder for searching addresses. When a user searches for an item it takes about 2 minutes for all the layers to be searched (takes too long). Under the search the user can specify a layer to search on, however...
