I have a similar problem to the issue posted here (gdal2tiles problem). I have 80 GeoTIFFs (4000x4000) with EPSG:27700 projection embedded and TFW and PRJ files. These I have built into a virtual raster using gdalbuildvrt which creates a 10x10 tile image that is 40000x40000 pixels. Using...

I would like to load a geoJSON (polygon) file into my leaflet map. I have seen examples where geoJSON is embedded into the javascript code but I can't find any examples showing how it is done with an external file. html, body, #map { height: 100%; } body { padding: 0...

I want to create tiled cache from raster file, so i downloaded gdal2tiles.py.Now i don't get what (and how) i must do with that python script file. أكثر...

I've carefully cut the collar off a set of USGS geotifs and I'd like to run through them with gdal2tiles but producing a vrt that undersands the alpha layer, or having gdal2tiles overlap two source files into one tile is not working. Some things I have tried have made all black pixels...

I'm trying to convert a 20 GB LZW compressed geotiff to a tilepyramid using gdal2tiles.Unfortunately, gdal2tiles seems not to be able to handle this, after running it for 10 hours it still hasn't reached the first "dot" yet. I tried this with a smaller (1GB) file and it worked fine. My...

I have done LC classifications using MODIS images (250 m spatial resolution) in 2000, 2003, 2006 and 2009. Coverage area is quite big (col and row are more than 15000 and 6000 respectively). Now I wanna do accuracy assessment. But I obtained a classification image in 2008 as a reference image...

I have a data question. I am interested in pulling the current typhoons in the pacific, but all I can find is the Joint Typhoon Navy site, which provides data but it is not easy to process. Does anyone have any python scripts to process this site? I assume you would have to scrape the html...

I have ArratList (N segments - array size is N) when: public class Segment { Node vertex_1; Node vertex_2; } public class Node { double latitude; double longitude; } And one static point - origin point. How to work with GeoTools in order to get ArrayList (size N) where each...

I am getting different X and Y values for tiles from gdal2tiles.py when in a PC (OSGeo4W - GDAL 1.9.2) environment and Linux (GDAL 1.10.1). It seems to me that the newer 1.10.2 x's and y's are wrong (not respecting the specified origin). Is this a bug, which result is correct, and how do I...

I am using gdal2tiles.py to render map tiles of some data. The file I use is generated by combining a .tif and .tfw using gdal_translate XX.tif XXn.tif Whenever I open up the file in QGIS, I see all the data: Next, I create tiles by gdal2tiles.py -p geodetic --s_srs "+proj=longlat...

I want to put a custom map onto cartodb, which, I believes, requires EPSG 4326. When I try making tiles with gdal2tiles, using a 4326 georeferenced image, I get the following error: ERROR 1: Too many points (10201 out of 10201) failed to transform, unable to compute output bounds. If I try...

I am trying to create tiles from tif images using the gdal2tiles command (at the OSGeo4W command line). I've been asked if it would be possible to create tiles at zoom level 12. Using the -z switch like so ... gdal2tiles --s_srs EPSG:32717 -z 12 input_tif.tif output_folder This creates the...

I have 70Gb of raster data from drone photography that I need to serve via Openlayers. The data is currently provided as georeferenced jpegs each is 175Mgb in size. What is the best strategy to cut these into manageable tile sizes for serving via the web. I have access to the gdal...

I'm a newbie in gdal2tiles & python but I would like to modify gdal2tiles to create 512px tiles for retina display (screen). Can someone suggest how I can do this? أكثر...

I'm in need to process a large batch of Landsat images with MapTiler and since the version I'm using (1.0 Beta 2) does not support multiple input files, I created a simple python script that calls gdal2tiles for every file. The problem is that using, apparently, the same settings, I get...

I have tried lots of variations, but can't seem to get gdal2tiles to do what it used to do. Prior version? images are 60N to 60S and 180W to 180E 9000 pix x 3000 lines. gdal2tiles keeps outputting doc.kml like so: 85.05112877980660 -85.05112877980659 180.00000000000000...

I've used gdal2tiles for generating tiles in number of different polar projections and always experienced the same problem — strange small picture inside normal 256x256 png with the rest of space transparent. I'm using -p raster option. That's how one particular tile looks like...

I downloaded this .tif image of the world (small version) from Natureal Earth and tried to convert it to tiles using Gdal2tiles in OSGeo4W. In the terminal, I used the following commmand: gdal2tiles -z 0-4 -w none -s EPSG:4326 NE2_50M_SR.tif and the process went smoothly, except that...
