How to integrate satellite and drone data into M&E workflows

Integrating satellite and drone data into M&E workflows enhances real-time, geospatial tracking of program impacts, such as environmental changes or infrastructure progress, building on prior AI tools like Sopact Sense and validation techniques discussed.uavsphere+1

Preparation Steps

Define M&E objectives first, like monitoring crop health or disaster recovery, to select data types—free satellite sources (Landsat, Sentinel-2) for broad coverage and drones for high-resolution details (RGB, multispectral, LiDAR). Preprocess both: correct radiometric/geometric errors, orthorectify images, and align to a common system like WGS84 using ground control points (GCPs) for accuracy.doc.arcgis+1

Integration Workflow

• Data Acquisition: Schedule satellite passes for temporal trends and drone flights with 70-80% overlap at consistent altitudes.

• Fusion in Software: Use GIS tools (ArcGIS Pro, QGIS, Pix4D) for layer stacking, pan-sharpening, or ML-based fusion to overlay drone details on satellite basemaps.epublications.marquette+1

• Analysis: Compute indices like NDVI for vegetation, generate change detection maps, and feed into AI models for anomaly alerts or predictions, validated via stratified k-fold on local data.galileo+1

M&E Applications

Store in cloud formats (GeoTIFF, STAC) and automate with Python (GDAL, Rasterio) for scalable NGO use, ensuring ethical checks like bias audits from earlier frameworks.evalcommunity+1
