Given your error, my guess is that when you are importing the file to GRASS, it is expecting a GRASS ASCII raster format, which has a header that looks like this: north: ####.### south: ####.### east: ####.### west: ####.### rows: ####.### cols: ####.### Instead of an ArcGIS ASCII grid, which has a header that looks like ...

I would advise creating a shapefile of image boundaries using QGIS and the Image Boundary Plugin. The following screenshot shows the results of using the plugin on 4 geotiffs.

Here is some of my C++ code for working with triangles: Structures, in order to understand my code understanding these structures is necessary: struct CoPair // linked list of coordinates { long ID; float X; float Y; float Z; CoPair *NxtPt; }; struct Tri // linked list of triangles made from 3 CoPair { bool Active; CoPair *A; ...

I'd start with GeoServer on the server side. You just need to put the files on the hard drive, create an ImageMosaic store, then publish whatever layers (perhaps just one) you need. The ImageMosaic is the critical part - that will turn your collection of aerial photographs into a single image. Note that there are likely to be some artifacts where the images ...

There are many solutions for your question, some more suitable than others based on constraints such space/memory available in your servers. The client side looks like simple because you do not want to overlay any other layer at this moment, so leaflet or openlayers can help you. The server side is a bit trick, since you need to decide how to provide your ...

Another option you could explore is using Tilemill to generate tiles from your GeoTIFFs. You can then just put the tiles on a webserver and call them using Leaflet. No need to set up databases or middleware. Basically you load the GeoTIFFs into TileMill and export it as MBTiles. This is MapBox's format for storing the tiles in a SQLite database. You then ...

The gdalbuildvrt program isn't the right tool for this task. It's for making virtual mosaics and multiband images. I suggest this approach: Define the domain in which you want results (geotransform, rows and columns). We used to call this a "canvas" back in the day. Warp (gdalwarp, nearest neighbor) your source TIFFs to that domain, producing TIFFs with ...

I had some damaged GeoTiff files. What happened is that a person ran the GeoTiff through Photoshop. Photoshop and most other drawing problems ignore the GeoTiff part of the tiff file and wind up bashing the spatial information in the header. You do not say what tools you have available. What I did to fix the problem was to use the coordinates that I ...

I was able to solve the issue with geotools java library. Extracting coordinates from either tiff and shapefile, we can get points from each tiff pixel by going over tiff with pixel-size step and checking if this point is inside of shapefile geometry coordinates.
