Elevation1 & 4 - Highly Precise Altrimetric Information

Elevation1 & 4 key features:

Accurate: Based on matching of very high resolution optical stereo imagery
Two Models: Digital Surface Models (DSM) including the "first surface" elevations & Digital Terrain Models (DTM) representing the bare Earth elevation available

Compliant: Suitable to HRE40 (E4) / HRE10 (E1) standards (military standards (NGA))
Tailored: Production on demand for your Area of Interest

Your advantages with Elevation1 & 4:

Elevation4 ideally suited for any kind of relief (urban or environmental)

Elevation1 ideally suited for any areas with little vegetation and / or no buildings

Production on demand for your Area of Interest

Elevation8 - Large-Area DEMs at a High Accuracy

Elevation8 is derived from SPOT 6 and SPOT 7 stereo and tri-stereo optical satellite data and provides an optimised fit for the needs of mapping or oil & gas applications, particularly when large-area coverage is required.

The satellite’s optimised combination of wide-area coverage and high-resolution image acquisition, supports the rapid collection of imagery and delivery of products. The models are available tailored exactly to your Area of Interest starting at a minimum of just 1,000km².

Elevation8 key features:

Accurate: Based on matching of high resolution optical stereo or tri stereo imagery, up to 3m vertical accuracy at 8m posting

Two Models: Digital Surface Models (DSM) including the "first surface" elevations & Digital Terrain Models (DTM) representing the bare Earth elevation available

Tailored: Production on-demand for your Area of Interest
Compliant: Suitable to HRE80 (military standard (NGA)) specifications

Your advantages with Elevation8:

Available anywhere in the world and suitable for large areas

Ideally suited for mapping, hydrology and exploration
