I have GPS data (X,Y, speed, CO2 and fuel consumption) for one truck for one trip. I want to import them in ArcGIS and to join them with the road network (map matching). I was thinking of applying "near" to the data points so that they can get road segments' id and then "summarize" to get data...

Not been able to access my Geoserver with Javascript. The Leaflet code running natively works in other javascript/HTML pages which connect on-line GIS servers. Added ENABLE_JSONP true to web.xml . Used this tutorial ...

I went to Raster --> Analysis --> DEM (Terrain Models) to compute slope. The slope ranges from 0-39.2311. Now I'm unsure of the correct way to calculate slope between 5-10% in the raster calculator. أكثر...

We've got some Point data we're displaying in a WMS layer using geoserver 2.2 (same problem on 2.3.1). We style it with the following SLD image/png 28 The problem is that when I click on the edge of the image displayed, the getFeatureInfo...

I have a DEM file and shape file, and I want to mix these two, and then select the min and max elevation of specific parts of shape file in Python. What should I do? أكثر...

I have been generally quite impressed with the mapping of the current war in Iraq and Syria. This is a complicated and rapidly changing conflict, and I find it highly convenient that major newspapers, magazines, websites, think tanks, and the indispensible Wikipedia provide comprehensive and...

Thirty major hurricanes, typhoons, and cyclones occurred in the northern hemisphere in 2015—the previous record was 23—and many of them reached places that don't see many storms. أكثر...

Need help figuring out how to make a vector overlay for a zoomified image using OL3. Am updating a project from OL2, where what I'm attempting worked fine. Project isn't true map data, the zoomify layer is a scanned document, converted to zoom tiles. Polygons represent the coordinates of...

All, In order to do some quick analysis using SQL spatial, I'd like to generate spatial objects using the STGeomFromText / ST_GeomFromText function. With point data, I can do this by geocoding an address and using desktop GIS to give me the X/Y, which I then turn into a point using a syntax...

I want to create a polygon and have it filled with strokes as in the image : Currently my style function looks like this : var tempObjectsStyleFunction = function(feature, resolution) {return [ new ol.style.Style({ fill: new ol.style.Fill({ color: feature.get('color')...

Spatial analyses and mapping in R have long been improving and expanding. Many of my colleagues now recommend (and use) R for GIS and other spatial analyses vs. programs such as ArcGIS. I'm curious about the opinions of this site's users: Which do you prefer, R or ArcGIS, and why? Perhaps...

I am trying to perform some raster math and wanted to try parallel processing in R using rasterEngine. I am able to run the script for a few minutes and watch my CPU usage increase substantially, but soon an error occurs and processing stops. Here is my code...

Using the ESA Toolbox named SNAP one can load a sentinel 2 data package and see a RGB view using the profile. I am wondering what this profile in mathematical terms are. Is it just information about which bands to use?Is it a weighting of the bands?Is it static across time/geo position? How...

ST_DumpPoints(geom) gives me something like this: ("{1,1}",0101000020E61000002DEDD45CEEB362C0CE1951DA1BC24E40)("{1,2}",0101000020E6100000C94AD826F1B362C09D4B7BC72CC24E40)...Where I want it to look like this seq lat lon 1, 61.1, -149.1 2, 61.2, -149.2... I've played around...

I'm working with administrative boundary polygons and am wondering when to keep the existing unique ID, and when to assign a new unique ID to a polygon. For example, if District A merges with District B and is still called District A, do I keep the original ID for District A, or create a new ID...

I hear this is the place to be if you have a GIS question. My problem is this: I need to create a new feature class with four different points on it from various x- and y- coordinates. What is the easiest way to do this? Step-by-step instructions would be helpful. I should also mention that I...
