Joint program supports initiatives that seek to understand the ecological and biological mechanisms that govern relationships between human-induced environmental changes and the emergence and transmission of infectious diseases.
Supported by NIH/NSF Ecology of Infectious Disease Program
Eco-Epidemiology of Chagas’ Disease
In Northwest Argentina – study area
Ikonos satellite image –
used for detailed mapping
Santiago del Estero
Dry Chaco - Semi-arid area; mean annual temp. of 22º C;
hot summers and cold winter nights
Local economy is based on exploitation of the (rapidly disappearing) forest: Wood-chopping, production of coal and hardwood posts.
The IKONOS satellite is a high resolution satellite capable of creating 1-m2 panchromatic and 4-m2 multi-spectral images.
Getting the GPS points and making the Sketch maps
in the field.
Get the IKONOS and process it.
Crop out smaller
Images for areas
Georeferencing the image with GPS points
2- Locate where they should overlay on the image
And end up with a comprehensive map structures.
And location data for further analyses
Project is a true collaboration
between UBA, UIUC, CDC,
Nat’l Vector Control Programme;
and includes a strong training component
