Problem in exporting TIFF File to Google Maps Files?

[Mona92]

Hi guys,

May I know what wrong with my code to export google map files from tiff file.
this is my code

chunk.exportOrthomosaic(path=tiles.zip, format=Metashape.RasterFormat.RasterFormatXYZ,                         image_format=Metashape.ImageFormat.ImageFormatPNG, raster_transform=Metashape.RasterTransformNone,                       dx=0.000001, dy=0.000001, blockw=256, blockh=256,write_kml=False, write_world=True) and the attachement is what happen after export.

Hello Mona92,

Does the export from GUI work properly if  you select the same parameters?

[Mona92]

my code work properly  in RGB image, but failed in mutispectral image to convert TIFF to google map tiles

first code for orthomosic image, and second for convert TIFF to google Map

chunk.exportOrthomosaic(path + "ortho7.tif", image_format=Metashape.ImageFormatTIFF, format = Metashape.RasterFormatTiles, raster_transform=Metashape.RasterTransformNone, write_kml=False, write_world=True)

chunk.exportOrthomosaic(path=os.path.join(path1,'tiles.zip'), format=Metashape.RasterFormat.RasterFormatXYZ,image_format=Metashape.ImageFormatPNG).

Hello Mona92,

What is the format of the source images: number of channels and bit depth?

Have you tried to perform the export via GUI (without using Python scripting) does it produce the desired result?

Have you tried to open the exported TIFF in any other GIS applications, like Global Mapper or Q-GIS - is it displayed properly?

=jpg, 3 and 4 channel, 8 bits

=yes, its showed good result

Have you tried to open the exported TIFF in any other GIS applications, like Global Mapper or Q-GIS - is it displayed properly?
= yup it showed good

but, previous problem already settle,  now I have another problem after tiles

this is my problem, when I  display the tiles at google earth, it  not map to their location and I can move the image as show in picture that I already attached to you

Hello Mona92,

When you export the orthomosaic to Google Map Tiles, there should be index.html file that should be opened to display orthomosaic over Google Maps, it's not intended to open individual PNGs from the exported structure.

I've tried to use your code for export in the latest Metashape Pro version (1.5.1) and it appears to work fine.

[Mona92]

but why this happened when i'm using this index.html? For development purposes only?
