I'm trying to generate tiles with gdal2tiles.py and the resulting tiles are stored as 18/132639/164219. If I do the same thing with MapTiler (the GUI variant of gdal2tiles) the tile result is 18/132639/97923. I want the results from MapTiler (97923), but just with gdal2tiles, as I want to do...

I am trying to generate map tiles using gdal2tiles for an area much larger than MapTiler can handle. However, my tile caches are not showing up on the maps. I checked gdal2tiles by running the same file through it and MapTiler - and the outputs come out differently. Here's my gdal2tiles...

I have a gdal2tiles code for getting tiff file. In my code I am getting true tiff format but it makes my dype uint8. I want int16 for dtype. how can I overcome it? I know I have to add gdal.GDT_Int16 somewhere but I don't know where... the relevant parts of the my code: default_tileformat =...

i am searching some webgl technologies to create 3d map with digital elevation data. for web tech. i have found ReadyMap SDK to create 3d map from TMS... in ReadyMap for elevation data it uses sth below to create a json data from tile which consists of tifs. map.addElevationLayer(new...

When you run gdal2tiles, by default it sets pixels outside your map area to black-transparent. I would like to set them to white opaque. Looking at the documentation... http://www.gdal.org/gdal2tiles.html it looks like the setting --srcnodata=NODATA might do it, but it doesnt explain what the...

I have multiple tile sources generated using gdal2tiles I'd like to present on the same map. So when presenting a tile I need to determine which source to serve it up from, checking against the bounds. Anyone know how to calculate the lat lon bounds for a single tile based purely on zoom, x...

Very simple question. I've executed gdal2tiles against a GeoTIFF coverage, composed by several TIFF files. I want to serve the resulting tiles using TileCache. In the TileCache documentation, I see how to create new layers, using as sources JPG images, WMS layers, MapServer layers, etc...

Im using the following to try to produce a tms tileset: gdalbuildvrt test.vrt *.tif gdal2tiles -p raster --zoom=0-6 test.vrt out Two tifs work fine, more than that and it seems to miscompute the resolution and i end up with tiles that have a small image top left with 3/4 of the tile empty...

I've executed gdal2tiles against 2 raster coverages: One big raster coverage, composed by several TIFF files. Example of tile: http://dl.dropbox.com/u/6599273/319.png One single TIFF file, geographically placed inside the coverage above, but that wasn't procesed in the previous step...

I have a folder with a gdal2tiles output: 6 levels of zoom (and folders), with subfolders and .png tiles. Is there a gdal tool to merge in a single geotiff file these .png tiles? Thank you very much, Andrea أكثر...

I have a map image that I have reprojected from OSGB36 to googleMaps projection (EPSG:900913). When I run gdal2tiles on the reprojected map, the results are not alligned with the google maps images (its not just out by a little bit but by 10's of miles). If I run it through MapTiler (from...

ArcGIS installs its own version of Python that is not officially registered with the system but can in reality be used just like a normal install. I personally prefer just to use this as my primary Python, but it is not always possible. The instructions below can help you let a different Python...

I am using ArcGIS 10.3 for Desktop. When I export a data driven MXD using a strip index (i.e. 3 pages into a single pdf) it works fine the first time I export it. However, if I try and export the same MXD again it crashes and I have to close and re-open the MXD. This only occurs when data...

I am using arcgis android sdk and I enabled the rotation in my mapview. I added picture marker symbols and I want them to rotate with the mapview the problem is that when the mapview rotates the graphics don't rotate with the mapview and I can't find an option to do that. while the default in...

I want to know that what is the type of projection (900913, 4326 or so on..) of long/lat co-ordinates. I happen to come across a slight confusion while querying planet_osm_lines when I dump (St_DumpPoints) LineString into point and trying to get long/lat from that point. In the following code, I...

I have a raster image at 15m resolution and trying to conduct subpixel classification in ERDAS. I extracted two AOI's (area of interests) from the image and used it for my signature derivation. But when I run the process I had this error message: image and aoi files have different map info...

In an attempt to create a python add-in for ArcMap that will pass x and y coordinates to another application via a mouse click on the map, I have written the following code. I need the output coordinates to be in WGS_1984 and therefore have to project a geometry object. The problem I'm running...

Bonjour, Je suis à la recherche de quelques conseils et infos pour faire évoluer le SIG dans ma boite. Nous souhaitons passer à ArcGIS avec une centralisation des données sur un serveur où tout le monde vient piocher. J'ai eu un RDV avec un commercial ESRI qui m'a encensée la solution ArcGIS...

Does anyone know if it's possible to query tables that are regular Postgres and not PostGIS with QGIS? I have a PostGIS database but want to access tables that aren't spacial - much like reading in a text delimited file. I've poked around the plugins but to no avail أكثر...

I have a tfwx file and when I open it in arcmap it is displayed as 4 bands. I would like to use the georeferenced file in qgis since I know nothing about arcmap. أكثر...
