I came across this map and would like to replicate the textured styling found along the borders. I'm starting with a multipart polygon but my process has perhaps too many steps. I'm using QGIS 2.8.2. Processing algorithm: Convert original polygon to lines Processing algorithm: Fixed distance...

I am currently attempting to create a Python Add_in tool which will perform a set of geoprocessing operations resulting in new values for a specific !shape.area!acres calculation on a new layer and then update rows in an existing feature class with these new values. I am using da.UpdateCursor...

I have digital orthophotographs from 2013 that I'm attempting to reclassify in an effort to extract all the cultivated/pasture land from. I'm using the "Reclassify by Ascii File" tool for this procedure. According to the NLC database values 81-84 are what I'm looking for and this seems to be...

We just launched geocoding autocomplete, delivering a dramatically better geocoding experience. You’ve probably seen autocomplete before when searching a map: as you type in a city name, like Washington DC, the search returns possible matches, saving you the trouble of writing your entire query...

I am trying make a layer of buildings, divided into apartments, by making polygons from crossing & intersecting lines in QGIS. When I use the vector/geometry tools/lines to polygons tool, I get just one polygon with no divisions at the inner lines, or otherwise odd polygons. The attached...

We are a GIS department using ArcDesktop and SDE 10.3. We are receiving service requests through a 3rd party web application (seeclickfix) that records the service request in WGS 84 lat/long. The application then transforms the coordinates into TN State Plane using the method described below...
