GeoTIFF is not visible on map, add_raster

[Flawks]

Environment Information

• leafmap 0.22.0:
• Python 3.10.12
• Operating System: Google Colab

Description

I've been trying to run the example notebook with my image in Colab: https://leafmap.org/notebooks/05_load_raster/
The add_raster adds the image layer and the leafmap map zooms to the respective coordinates of the GeoTIFF file. However, the image is not visible.

What I Did

I added some changes to the original notebook:

• added !pip install localtileserver line because otherwise the leafmap map returns the prompt about it failing to cache the image
• added image = 'bogota.tif' line for the input image that can be obtained from bogota.tif

The command I used to add GeoTIFF image to the map:

m.add_raster(image)

The output of the lefmap map:

How it should look like (QGIS):

I also tried changing the layers opacity in the map GUI, but it didn't help.

Sounds like a Windows issue. See #492

It works fine on my Linux machine. Try installing localtileserver with conda rather than pip.

hello,
I am running into a similar problem. I am trying to run the nb example 91_raster_viz_gui.ipynb but the image is not plotted.

I installed leafmap in a linux machine running Ubuntu. I had some issues creating an environment but eventually it is not giving errors when importing leafmap:

conda create -n pyleafmap python=3.10
pip install leafmap
conda install ipykernel
python -m ipykernel install --user --name pyleafmap --display-name "Python (pyleafmap)"
pip install --find-links=https://girder.github.io/large_image_wheels --no-cache GDAL
conda install -c conda-forge xarray dask netCDF4 bottleneck
pip install rioxarray
pip install localtileserver
pip uninstall matplotlib
pip uninstall numpy
conda install -c conda-forge matplotlib
pip install numpy
pip uninstall leafmap
pip install leafmap

and here is the notebook:

any ideas are greatly appreciated.

If you have conda, you should avoid using pip to install packages. Try creating a fresh conda env:

conda create -n geo python=3.11
conda activate geo
conda install -c conda-forge mamba
mamba install -c conda-forge leafmap localtileserver
