CartoSat-1 Panchromatic Archive and Euro-Maps 3D Surface Model

2005 to 2019 panchromatic satellite imagery and a 5-meter resolution digital surface model. The archive includes PAN-Aft, PAN-Fore, and Stereo products with 2.5-meter resolution and 27 km x 27 km coverage. Data is provided by the European Space Agency (ESA) in cooperation with the German Aerospace Center (DLR).

Use Cases

• Generate 3D city models and terrain analysis using the 5-meter post-spacing Euro-Maps 3D DSM.
• Perform stereo photogrammetry and create digital elevation models from the 2.5-meter resolution PAN-Aft and PAN-Fore image pairs.
• Conduct land cover classification and change detection over a 14-year period using the ortho-corrected panchromatic imagery.
• Assess vertical accuracy for elevation products by comparing against the DSM's stated LE90 of 2.5-10 meters.
• Create orthorectified base maps by applying ground control points to the system-corrected CartoSat-1 imagery.

Strengths

• 14-year temporal coverage from 2005 to 2019 for global CartoSat-1 imagery.
• High 2.5-meter spatial resolution for panchromatic imagery and 5-meter post spacing for the digital surface model.
• Products include system-corrected, radiometrically corrected, and ortho-corrected (DN) versions for different analysis needs.
• Euro-Maps 3D DSM provides detailed flanking information including pixel-based quality and traceability layers.

Limitations

• Worldwide data outside the Neustrelitz footprint requires contacting user support as no public catalogue is available.
• Ortho correction for some products may require users to supply their own ground control information and DEM.
• Absolute vertical accuracy for the DSM is specified as 5-10 meters LE90, which may be insufficient for high-precision applications.
