Mission Definition & Objectives

Mission: Forestry Resources in the Azores:

Distribution of Production Forest and Exotic Woodland vs. Conservation ofBiodiversity in Native Forest

Database for Macaronesian plantspecies (distribution, habitat)

Modelling tools for predictivegeographics

Impact of accelerated land use andother environmental change on thedistribution of organisms

Biodiversity conservation

Potential usage for renewableenergy

Forestry management for theestimation of biophysicalparameters: biomass, age, diameterat breast height

Field work vs. remote sensing

Direct Mission Set Derived Products

BuildSystem

ProcureSystem

FilterPrisma

Line sensors can achieve higherresolutions

TDI ensures a longer integrationtime

Wavelength separation with aPrisma isn't possible because ofwavelength overlap

Procuring space qualified hardware

ensures a high TRL but isexpensive
