Calling gdal2tiles.py in AWS LAMBDA function

I'm trying to call gdal2tiles.py in AWS Lambda function using GeoLambda layer. I can't figure out how to call this script form the lambda function.

My lambda function looks like this so far:

    import json
    import os
    from osgeo import gdal
    def lambda_handler(event, context):
       
         os.system("gdal2tiles.py -p -z [0-6] test.jpg")

In the log I have this error: sh: gdal2tiles.py: command not found

Any idea how to solve this? Thank you.

one way to do it is to import gdal2tiles utilities from the GeoLambda layer that you added to your lambda function.

For example:

gdal2tiles.generate_tiles('/path/to/input_file', '/path/to/output_dir/'), nb_processes=2, zoom='0-6')

Edit: Ok i made it to work with these set of layer attached to the lambda. The first 2 layers were straight from the Github

• arn:aws:lambda:us-east-1:552188055668:layer:geolambda-python:3
• arn:aws:lambda:us-east-1:552188055668:layer:geolambda:4

The 3rd layer is our gdal2tiles which is created locally and attached to lambda fucntion

• arn:aws:lambda:us-east-1:246990787935:layer:gdaltiles:1

you can download the zip from here

And i hope you added the below Environment vairable to your lambda function configuration

• GDAL_DATA=/opt/share/gdal
• PROJ_LIB=/opt/share/proj (only needed for GeoLambda 2.0.0+)
