| Price/km² (*) | Free to 0.75 EUR/km² | 0,95 EUR/km² to 50 USD/km² | 10 to 100 EUR/km² | ||
| Exemple of optical multispectral sensor |
|
Aerial photos in true or false colour | |||
| Assets in mapping for demining | Able to cover large areas, change detection since the 80s | mage acquisition more dependant on cloud conditions, images available also in near infrared | More independant then satelitte sensors from cloud conditions, required a suitable available air-plane, required national authorization | ? | Vertical or oblique views of small objects of interest (bunkers, …) |
