Objectives of research activities

Contribute with new knowledge

Data retrieval Adaptation/development of

methodologies for enhancing the detection capacity of

satellite images

Development of support tools for decision and policy makers: Monitoring and early warning

systems Software “Pacha Ricaj”

Capacity building: Under and post-graduate

programs Governmental entities

Satellite images • Are the most efficient and economic tools for

monitoring events that occur on the sea/land surface • Can be used for implementing monitoring systems • There is an important availability of free images

(important for sustainability) • Images available from the early 70’s (Landsat) • Offers the possibility to retrieve data from

inaccessible locations and are useful for filling spatial-temporal gaps in data

• There are several useful indices: NDVI, NDWI, LST, SST, etc.
