I have two point clouds obtained via structure from motion (ground photos of sand-dunes + Visual SfM/Agisoft Photoscan). If I wanted to generate a DEM from these point clouds and difference them to look at elevation/sediment change, how would I go about doing this? Is there any free software...

i want to read all spatial data. Right now i have done this Geodatabase geodatabase = Geodatabase.Open("../../samples/data/Querying.gdb");// String allTables = geodatabase.DataSetTypes.; foreach (var ds in geodatabase.GetChildDatasets("\\", string.Empty)) {...

I have a plugin where I create a raster and write in that raster. This worked before but now in QGIS 2.10 doesn't work. I search for gdal API tutorial and I didn't find ReadAsArray as I have in code. Can you tell me if this doesn't exist anymore? Thanks, أكثر...

If I create a 100mx100m square it is deformed when I rotate it. I can understand why this would happen with a huge shape, but surely something only 100m in size should rotate without significant distortion. I'm trying to add the rectangle onto a new layer which will be exported as a .kml. The...

How to make a raster with values that are the sum of all points inside each raster cell? The burn value is a specific attribute. Using gdal_rasterize or gdal.RasterizeLayer(), the resulting raster only has the value of a random (or probably the first or last) point inside a raster cell. I’ve...

I have a folder with numerous .asc raster files that each accompanied by a corresponding .prj file. The file basename is the same for both files. The projection however can vary between all of them (they are currently in various different UTM projection). What I want to achieve is to standardize...

Would it be adequate to add polygons to my existing ETRS89 data using a basemap as a reference (using ArcGIS)? It does actually line up quite well with my existing polygons and would be the easiest way to do it. I want it to be exact though. The orthophotos are just too big to load quick...

Trying to clip a line layer with another renders an empty shapefile. I've looked through older threads and have made sure that the CRS is the same (they do align) and that I've converted multipart files to singlepart ones and use these for clipping. Have tried with numerous line layers from...

I have a set of over 20,000 villages in xls that only have a ward assigned to them - no coordinate. I do have a ward shapefile. Now I have created a data set of random points (shp) and spatially joined the ward information. So all my random points within the ward state the name of the ward they...

I have recently started experimenting with QGIS's flow mapping functionality. I am having trouble finding any origin/destination data online and I'm hoping someone can help? It can be for anything. I just want to experiment with the functionality some more. I have used data from OpenFlights...

I have to choose which format should be used for a project which entails scanning 2000 (mostly coloured) building plans in scale 1:1000. I am tending towards standard TIFF but due to the fact that the scans are going to be georeferenced I am also considering GeoTiff to avoid getting the tfw...

Geonetwork seems use OpenStreetMap and MapQuest as default WMS(or WMTS).But I found nothing about that in the document. Can I change it to other WMS or WMTS?How can I do? أكثر...

I got a dataset of streets, which are displayed as line segments. In another, independent dateset I have roundabouts as a point geometry. Starting from these datasets, I want to count the number of streets which lead to the roundabouts. I would start to make a buffer around the point-geometry...

I've been doing my research on how to import shape files into Microsoft SQL Server 2012. and am still unable to figure out how to do it after hours of playing around with it. I'll document what I've done below: I first downloaded the latest Census TIGER Shape files at the census block level...

Is it possible to use the functions from ArcMap's Main Menu (for example Add Data, Start Editing) in my model? I cannot find a way to add any other functions except Toolboxes. أكثر...
