Deforestation Detection in Real time, confirmed 836km2 of deforestation in Amazon. 577km2 out of 836km2 were in Pará and 124 in Mato Grosso.
In Amazonas, Maranhão and Rondonia respectively was confirmed 47 km2, 38km2, and 35km2, while other states did not have a significant deforestation in July, whose month the presence of clouds coverage is very low so that it was possible to make the observation in 77% of the area.
Check below the map with clouds coverage areas and the spots where DETER pointed out the alerts on July.
DETER is a system of the National Institute for Space Research employed for mapping both shallow cut and areas in process of deforestation by forest degradation.
Due to inconstant clouds coverage from one month to another, and also to satellites resolutions, DETER’s data do not represent a reliable evaluation of the monthly deforestation in Amazon. To computing the annual rate of deforestation by shallow cut in Amazon, INPE makes use of PRODES system.
Evaluation
An illustration of DETER’s data shows that 95% of the alerts from July were confirmed as deforestation. In that month, 85% were classified as shallow cut and only 10% as degraded forest (being 6% of degradation of high intensity and 4% of moderate and light intensity).
DETER system
In operation since 2004, DETER (Deforestation Detection in Real Time) was created by INPE as an alert system to support the surveillance departments responsible for monitoring deforestation process. Both shallow cut and area in process of deforestation are mapped. It is possible to detect only polygon of deforestation with areas bigger than 25 hectares due to space sensor resolution.
However, the smallest sensor resolution used by DETER is compensated by the daily observation capacity, that makes the system a perfect tool to inform quickly the surveillance organs about new deforestation.
