I have a file containing a large number of points that were digitized from scanned plans in CAD. The points represent pit lids at an industrial facility. When the point file is laid over the aerial image the points are all out by varying amounts. Around the perimeter of aerial I can see a...

i'm using the leaflet-gpx plugin to draw various .gpx files on my map. How can I change the color / style of it ? gpxvar[{{loop.index0}}] = new L.GPX("{{url_for('static', filename='gpx/' + r )}}", { async: true, marker_options: { startIconUrl: "{{url_for('static'...

I need to calculate to azimuth between two points. I'm using Projnet and GeographicLib to get the azimuth. So I have a UTM projection map then I need Projnet to get Lat/Lon coordinates because GeographicLib uses Lat/Lon to calculate this azimuth. Ok I get the angle but now my question is if I...

This question might not seem related to GIS, although GIS can easily provide the right answer by analyzing a number of different spatial datasets. How is it possible to account for the fact that some small cities have a land area which is far greater than that of bigger cities or even...

I am new to GIS and working with gridded data so please excuse me if my question is simple or if I miss an obvious point. I want to work with 30 Arc Seconds Nightlight Data (my data comes from NOAA: http://ngdc.noaa.gov/eog/dmsp/downloadV4composites.html). To my understanding with 30 Arc...

Getting an error with a very simple compress script. This script works perfectly fine within arcmap, but I want to make this into a scheduled recurring script. import arcpy from arcpy import env env.workspace = r"\\UNC PATH \dbconnection.sde" arcpy.Compress_management(r"\\UNC PATH...

In QGIS 2.12 the curves tool is integrated by default, I know. I would like to test the Spline Plugin whether it works better for my purpose or not (purpose is just to digitize streets mit nice curves, that's all). The problem is, it doesn't work. There are the same edged lines as the...

I did a query to look for certain things. However it only outputs the lat and long coordinates, there is no city data available. I'd like to have the city it belongs to / closest city though. I know there are websites where I can convert a single coordinate to a city. But since my initial...

I have three ascii files including longitudes, latitudes and pixel values. I just wonder whether there is anyway to display a map from the three files and save it in geotiff without merging them into a single file. I am using QGIS and ENVI-Idl. أكثر...

I am writing a script for the processing of different hyperspectral datacubes. The datacubes contain flight lines that I've recorded with a UAV. In total there are 10 flight lines that need to be processed and mosaiced. The files are in .bsq format and contain 101 bands: class ...

I've got building and terrain models of a city in 3DS format. I'd like to transform these models to tiff images in order to create some kind of digital surface model (pixel value = height or altitude) I've done some quick tests with FME...

I'm using QGIS Server and an OpenLayers-based web client (in EPSG:3857). I have a QGIS project that I want to serve with QGIS Server, containing layers in several CRS, including custom ones. Everything shows up correctly in QGIS, and on the fly projection is enabled. My QGIS project...

I have the following RGB raster and would like to remove the black background (where R=0, G=0, B=0). I'm using QGIS. The problem is that the raster itself also contains black pixels. Using the option of QGIS to make all RGB(0,0,0) pixels transparent is therefore not an option, since it will...

When segmentizing a geography line in Postgis, the max segment length does not seem to be respected when the line is more than 3000km. The error grows when the length of the line increases. Below the code to demonstrate it:*) The printLineSegmentLength method logs the length of each segment of...

I just wondered if anyone could help me out....I`ve got a table with coordinates of some postcodes and I want to display them in AcrMAP. The points should be on the street centrelines. When I bring in the csv file and right click to display the points, they are being located on the properties...
