Overview
What We Deliver in Remote Sensing
TANGIS operates an enterprise remote sensing capability covering the full pipeline from satellite imagery acquisition to analysis-ready data products. We work with commercial satellite providers including Planet, Maxar, and Airbus, as well as government archives (Sentinel-2, Landsat). Our analysts are experienced in land cover classification, crop monitoring, forest change detection, urban expansion mapping, and disaster damage assessment across East and Central Africa.

Challenges We Solve
Inaccessible Terrain
Large swathes of Tanzania and East Africa are physically inaccessible for ground surveys — satellite imagery is the only viable data source.
Change Monitoring at Scale
Government agencies and NGOs need to track land use change, deforestation, and urban growth over time but lack the processing infrastructure.
Complex Imagery Processing
Raw satellite data requires atmospheric correction, orthorectification, and band mathematics before it can be used for analysis.
Multi-temporal Analysis
Understanding trends requires consistent processing of imagery archives spanning years or decades — a specialist capability.
Our Approach
How We Deliver Remote Sensing
Imagery Acquisition
We identify the optimal satellite constellation, resolution, and temporal parameters for your analysis, then acquire or access archived imagery from commercial and government sources.
Pre-processing
All imagery undergoes radiometric calibration, atmospheric correction, orthorectification, and cloud masking before analysis.
Classification & Analysis
We apply machine learning classifiers, spectral indices (NDVI, NDWI, NDBI), and object-based analysis to extract the information your project requires.
Accuracy Assessment
All classification outputs are validated against ground truth data using stratified random sampling and confusion matrix analysis to ISO-standard accuracy thresholds.
Data Products & Reporting
We deliver analysis-ready spatial data products, technical accuracy reports, and — where required — integration with your GIS platform or dashboard.
