MeshRF Dataset Setup

This toolkit allows you to download and configure 10m resolution terrain data (NED/3DEP) for any region in the US, including the Pacific Northwest as an example.

Quick Start (PNW Region)

If you just want the standard Washington/Oregon dataset:

1. Download the PNW data following the steps in DOWNLOAD_GUIDE.md (Step 4 details the PNW coords).
2. Move the downloaded ZIP files or tiffs to the data/ folder.
3. Run PowerShell -ExecutionPolicy Bypass -File .\scripts\2_process_data.ps1.
4. (Optional) Run PowerShell -ExecutionPolicy Bypass -File .\scripts\3_compress_data.ps1 to save disk space.
5. Run PowerShell -ExecutionPolicy Bypass -File .\scripts\4_auto_configure.ps1.

Custom Region Guide

To set up MeshRF for your own area (e.g., Texas, California, etc.):

1. Download Data

1. Open DOWNLOAD_GUIDE.md to see how to target your specific area.
2. Download the ZIP files as instructed.

2. Process Files

1. Move all downloaded ZIP files to the data/ folder in this repository.
2. Run:

PowerShell -ExecutionPolicy Bypass -File .\scripts\2_process_data.ps1

• This extracts the USGS data and renames it to the format MeshRF needs.
• It automatically handles any coordinate (North/South/East/West).

3. Compress Data (Optional)

Run:

PowerShell -ExecutionPolicy Bypass -File .\scripts\3_compress_data.ps1

• This step compresses the huge GeoTIFF files using LZW (lossless).
• It typically reduces the dataset size by 50% or more.
• Requires GDAL installed (the script will tell you if you need it).
• You can download GDAL from GISInternals (look for the latest stable release and download the -core.msi installer).

4. Generate Config

Run:

PowerShell -ExecutionPolicy Bypass -File .\scripts\4_auto_configure.ps1

• This script scans your processed files to find the exact latitude/longitude bounds.
• It updates (or creates) data/config.yaml automatically.
• It prints the environment variables you need to check in docker-compose.yml.

5. Verify

Run:

PowerShell -ExecutionPolicy Bypass -File .\scripts\5_validate_setup.ps1
