I would like to draw a grid whose cells are all squared on a given shape file. The shape file has the information of U.S. map at zip code or county level. I need to create the squared grid (with a resolution such as 1000 meters) and then get latitude and longitude of each grid point...

I have shapefile containing polyline and I want to specify bends, i.e.: factorize polyline into vectors measure an angle between consequent vectors consider each angle as concave or convex; let's assume concave angle receives plus sign, while convex angle gets minus, as shown below...

The Hyperbola depiction of how the GPS equations are solved: From several psuedoranges measured at the same time, we can calculate the (absolute) difference in the distances between us and these GPS satellites. 2 satellites gives us 1 known difference in distance, and we can plot our...

I'm currently developing on ArcGIS 9.3 I have created a 'temporary layer' placed a IPolygon into the temp layer it will then pop up a form to let user key in information, once the user confirms, the IPolygon will be shifted from the temporary later to another layer. I'm having...

Is there a tool that can push features away from either the same feature or a completely different one. For instance, if I had two points within 1 meter of each other, but wanted them to be 5 meters from each other. Could I push/relocate one of the features 5 meters away? I am using...

After using some non usual SRC for demonstration purpose, I wish to clear my "Recently used coordinate reference systems" list for the sake of praticity. Is it possible? QGIS 2.10.1 أكثر...

I have a table in Postgresql / PostGIS containing county geometries. This table was created by importing a shapefile. I verified the geometry was imported successfully by importing the table into QGIS to view the polygon positions and ensure everything was drawing correctly. So, now I have...

I have been working to improve OpenStreetMap data in my local area and I've found something that I think is a problem but I can't figure out how to fix it. The basic problem is that the Jefferson County Courthouse building in Golden, Colorado doesn't render the building outline on...

We've used OSM Place Search plugin daily with QGIS 2.2, 2.6 and 2.8 and it's been great. However, it stopped working last week for myself and several other inter-office users. We enter search text, hit the arrow button and nothing happens. No error, no spinning wheel, nothing. Here's the...

I am having trouble with the output of the "Tabulate Area 2" tool in the following update: http://blogs.esri.com/esri/arcgis/2013/11/26/new-spatial-analyst-supplemental-tools-v1-3/ I have a layer of overlapping buffers (polygon) as the zones and then a layer of parks where I'm trying to...

I have employment data which are huge - about 500 data for each category, like agriculture field, fishing field etc. Now I want to categorise this data in to 7 ranges. Suppose 50-100=2, etc. for producing an agriculture map of a country by showing these categories as a legend. I don't want to...

I have a question on the GPS positioning algorithm. In all books I've read for 3D positioning we need four satellites, and I don't understand why. We need to calculate three variables: x, y, z. We know when satellite send the signal to earth and when we receive it we can measure the time the...

SAGA has a feature that determines flats. Does anybody know how they define a flat? If I start with a raster, each pixel is flat - so it has to be more sophisticated than that. I would like to be adjust the thresholds to consider it a flat if two pixels are within 15m vertical of each other...
