REMOTE SENSING
OPTICAL RS
Optical satellite data are ideal for mapping vast and inaccessible territories anywhere in the world. Spatial resolution, which can be as fine as 30 cm for commercial data, allows highly detailed territorial mapping. Spectral resolution, characterised by tens of bands, can be used to classify any land cover type, based on its spectral properties.
Outputs:
- PAN/MS orthophoto map
- DSM / digital surface model
- DTM / digital terrain model
- surface classification

RADAR RS
In comparison with optical sensors, the main advantage of radar sensors is the possibility of remote sensing at night or in cloudy weather. They are active sensors that detect and measure the phase, intensity, and polarity of the reflected and backscattered radiation. Depending on a specific application and sensor, radar sensors' resolution varies from tens of kilometres up to 0.25 m.
Outputs:
- Terrain model
- Deformation model
- Intensity raster
- Coherence raster
- Object detection
- Surface classification

COPERNICUS
COPERNICUS is a programme operated by the EU and ESA that has revolutionised the remote sensing data and service availability. The Copernicus programme's cosmic segment consists of a constellation of Sentinel 1-5 environmental satellites, continuously monitoring planet Earth's surface, oceans, and atmosphere since 2014. The data are freely accessible to all users.
- Sentinel-1 (a radar)
- Sentinel-2 (a multispectral sensor)
- Sentinel-3 (a multispectral and radar sensor,
an altimeter)
- Sentinel-4, 5 (for atmospheric monitoring)

PLANET LABS
The key advantage of the Planet Labs company is its unprecedented data collection capacity. Due to 130 PLANETSCOPE sensors, the company can scan the whole Earth's surface every day. The spatial resolution of such data is 3 m. Besides that, the company has 15 SKYSAT satellites that can photograph and scan any selected area with an 80-cm resolution several times a day. PHOTOMAP is also one of Planet Lab's official partners and data distributors.
Optical data:
- PANETSCOPE − GSD 3.0 m
- RapidEye − GSD 5.0 m
- SkySat − 0.7 m
