Google Maps Tile Export

[Max]

Well, this is my first post here but I have been using Photoscan for over a year now and have found it to be an excellent tool which covers almost every aspect of UAS imagery processing. The two portions of processing which I do outside of Photoscan are RAW conversion to TIF and conversion of the exported mosaic into tiles which can be displayed using Google Maps API. I don't really expect Photoscan to do RAW work, as that would be pretty complex and unnecessary to implement, but it would be nice to see a Google Maps tiling engine.

Since Photoscan will already export the orthomosaic as a KML or tiles, it seems like it would be pretty easy to add the zoom layer tiles and create the HTML file that allows the tiles to be easily embedded in a website. I know there are a decent number of programs out there that do this but the free ones tend not to be great and MapTiler, which does a great job, is obscenely expensive.

I am also very interested in this and share Max's sentiments.

Any update on this?

Something like gdal2tiles can do it using GeoTiff, but I'm not sure about if google tiles format is supported.

Hello photoscan_user,

Have you tried to use File Menu -> Export Orthomosaic -> Export Google Map Tiles option? Does it fit your needs as expected?

Looks promising, what export format it corresponds to?

Raster format in [RasterFormatTiles, RasterFormatKMZ, RasterFormatXYZ, RasterFormatMBTiles, RasterFor-
matWW]

Hello photoscan_user,

RasterFormatXYZ corresponds to Google Maps Tiles export format.

It works, but how to control number of LOD levels? Now I have 16-20 levels, does number of levels depends on dx,dy params?

chunk.exportOrthomosaic(path=os.path.join(OUTPUT_TILES_DIR,'tiles.zip'), format=PhotoScan.RasterFormat.RasterFormatXYZ, image_format=PhotoScan.ImageFormat.ImageFormatPNG, dx=0.000001, dy=0.000001, blockw=256, blockh=256)
