We have an algorithm which requires us to produce a score based on the distance from any given cell in an output raster to a score calculated from the distances of the 3rd closest, 4th closest, and 5th closest point features in a separate feature class. For example, our score might be...

I'm trying to utilize line contour data to find the volumes of local depressions. To do this, I want to copy the closed loops formed by depression contours into a polygon feature class to find the area of the loops. I've done this several times in ArcGIS 10.0 successfully by selecting the...

Feature layers are often the best type of layer to use for visualizing your vector data in web maps. They are easily placed on top of tiled basemaps for geographic context and support interactive queries and selection, on-the-fly styling, and pop-ups. This post describes several tips for...

I am trying to use this map as a raster but I am not having any success in QGIS. I tried in Georeferencer to open raster and used these settings: Transformation: Thin plate spineResampling Method: Nearest NeighborTarget SRS: Pulkovo 1942 (and others) Then I input five points at major lat/lng...

I have been using GIS for a few years now but only since I've started using QGIS have I come across these terms. I have tried looking them up online but everything is very technical. I was hoping someone could explain in simple terms what they are/do. Sometimes when I am looking up how to do...

I'm a relative beginner with leaflet/mapbox but we are building a website with a set of different TileMill layers, each of which have different interactivity. We had been switching layers with L.control.layers, which worked fine as long as we only had a "hover-over" tooltip - the tooltips would...

The Intro to QGIS class is headed to Florida. I’m going to SHRUG to throw some FOSS4G into a pile of ESRI Related training. Given with how the last QGIS class happened I have some excitement that I get to inspire some people to do something different with their GIS. I’m also contemplating a...

I have two separate computers, each of which are running ArcGIS Desktop 10.3.1 and PostgreSQL and PostGIS 2.1.7. The only difference is one is running PostgreSQL 9.3.4, the other is running 9.3.5. I am trying to make a simple (or what should be simple) connection to DBMS. I have properly copied...
