Terra-i - Long Version English
Transcript of Terra-i - Long Version English
Cash crops, shifting agriculture, livestock and mining are the proximate drivers of local deforestation
An initiative for monitoring forests and other natural land covers in Latin America and the Caribbean based on
the use of geospatial tools and data
What is Terra-
Tool detecting natural vegetation loss resulting from human activities.
Near real-time system, producing maps every 16 days.
First continental scale tool in operation and the first to work outside of the Brazilian Amazon.
Minimum change area detected:
~6.25 ha or ~8 football fields
Temporal coverage: from 2004 to current date
For every 16 day period Terra-i tracks the areas of rapid forest cover change
Peruvian artisanal mining
Mining zone in Madre de Dios, Peru
The Case of the Amazon Basin
Using Terra-i data and independent
datasets to create future scenarios of where
land-use changes are likely to happen
Terra-i has been used within the
Policy Support Systems to understand the impact of recent land cover change on hydrology and the production and delivery of ecosystem services.
- Ongoing support and project promotion on social networks -
- Explore, visualize and download Terra-i data-
Normalized difference vegetation index (NDVI) represents the amount and vigor of vegetation.
Vegetation Index (MOD13Q1 MODIS Product , 16 days, 250m)
This process gives us greater automatization abilities, synchronizing from the download to post-processing stages of MODIS data
MODIS tile level analysis
TRMM is led by NASA and the Japan Aerospace Exploration Agency (JAXA). It monitors and studies tropical and subtropical rainfall.
Precipitation Data of the Tropical Rainfall Measuring Mission (3hours, 28km)
Research methodology overview
The methodology can be split into two main steps:
Bayesian-probability based neural network (BNN) learns how the greenness of a given pixel responds to a unit of rainfall
Calibrated model is run to identify fluctuations in greenness that cannot be explained by rainfall or by previous state of the vegetation
The detection step (using data from 2004 to present)
The training step (using data from 2000 to 2004)

Participation in other conservation initiatives
If there is a significantly large difference between the values predicted by the model NDVI and NDVI values captured by the satellite, then this difference is reported as
Most of the process is automatic
A large quantity of data is being processed
Each MODIS image is about 220 MB
Every 16 days, 34 MODIS images are processed...
