Pick safe candidate landing regions on Mars and visualize the planet’s topography.

• Landing-site selector: Scans a grayscale MOLA DEM, ranks rectangles by smoothness (std dev) and relief (peak-to-valley), and shows the overlap.
• Elevation profiles: Plot a west–east elevation cross-section at a chosen latitude (e.g., through Olympus Mons).
• 3D surface plot: Quick 3D view of the DEM so you can rotate/tilt and see relief.

**Note**: This is a demo/scoping tool (not a mission-accuracy selector).

• Python 3.9+ (works with Anaconda/conda or standard Python)
• Packages listed in requirements.txt

If using a conda environment:

conda create -n mars python=3.10 -y conda activate mars pip install -r requirements.txt
