GeoTIFF Map Reader

This repository contains a Marimo notebook (MapReader.py) designed to explore, audit, and visualize a collection of GeoTIFF files.

Features

1. Random Sampling and Previewing: Selects random TIFF files from directories and downsamples them for a quick visual preview.
2. Geospatial Audit: Extracts metadata from the TIFFs (such as Dimensions, Bands, Color Space, Data Type, and Coordinate Reference System) and displays the results in a Polars DataFrame.
3. Interactive Mapping: Plots the rasters on interactive maps using leafmap, handling CRS transformations so the images are correctly placed on basemaps.

Dependencies

The notebook automatically attempts to install necessary dependencies, including:

• numpy
• pillow
• polars
• rasterio
• leafmap

Usage

Run the notebook using Marimo:
