Projection and nodata issues with geotiff about localtileserver

[banesullivan]

I have managed to fix "No available tilesource" issue by projecting the input image correctly

I'm glad you got the projection fixed and are now able to load the image!

The coloring issue is due to the raster missing the nodata field and the default color interpretations not being set in the file. Unfortunately, you may need to recreate the raster because the nodata pixels are filled with 45 in this particular image which is in the middle of the valid data range of 0 to 255 for RGB colors.

You can mostly work around this though by specifying the nodata value and which bands to use for RGB with localtileserver:

from ipyleaflet import Map
from localtileserver import TileClient, get_leaflet_tile_layer

client = TileClient('20MAR30103630-M2AS-014050267010_01_P001_byte.tif')

l = get_leaflet_tile_layer(client, nodata=45, band=[1,2,3])
m = Map(center=client.center())
m.add_layer(l)
m

Hey, @gtgrp-user - the No available tilesource error is somewhat of a catch-all error and the real issue could be one of many things.

Would it be possible for you to share the data file 20MAR30103630-M2AS-014050240020_01_P001_calibrated_QUAC_byte.tif so that I can investigate and reproduce?

Hi @banesullivan,

I have managed to fix "No available tilesource" issue by projecting the input image correctly. However, I have encountered the following issue:

Instead of RGB, I see the above image. RGB image is available here for you to investigate and reproduce the issue.

I have managed to fix this by converting the image to PNG format. However, I have expected the tif format to work!

Thanks a lot. It works as you suggested. I really appreciate your time.
