🗺️ Flask Raster Viewer

A simple Flask web app to upload, georeference, and visualize raster files (GeoTIFF .tif, Sentinel .jp2) using Leaflet.

📦 Features

  • Upload .tif, .tiff, or .jp2 files
  • Automatically:
    • Converts .jp2 → .tif → .png
    • Extracts WGS84 bounds with GDAL
    • Displays the raster on a Leaflet map
  • Toggle layer visibility on the map

🚀 Quick Start

1. Clone this repo

bash git clone https://github.com/azeemk210/flask-raster-viewer.git cd flask-raster-viewer

2. Create environment

Using conda (recommended)

bash conda env create -f environment.yml conda activate geoapp

3. Run the app

bash python app.py

Then open http://localhost:5000 in your browser.

📁 Upload Format

Supported file types: - .tif, .tiff (GeoTIFF with georeference) - .jp2 (Sentinel-2 imagery)

After upload: - The raster is converted to .png - Bounds are extracted and passed to Leaflet - Map auto-zooms to the raster extent
