  • Abstract
  • The data represents yearly cumulative decrease detections of land cover change since 2004 to updated date (April 2015) . The data processed is in Shapefile format, with WGS_1984 Web Mercator projection. The original data in raster format is available by MODIS tile in the website, http://www.terra-i.org, it has a 250 m spatial resolution and temporality by 16 days. The input data is derived from the USGS/NASA MODIS and TRMM data, the detections were made using algorithms described by Reymondin et al. (2012). The data processed are images of 2004 to 2014 and were processed in July 2015. The shapefile processed has polygons that represent yearly cumulative decrease detection. The values 1 represents the polygons (pixels) with No data and the other values represent the polygons years (2004 to 2015). The attribute table has a field with the total area in hectares of the detection of change, and a field with the year that it happened.

  • Purpose
  • The data was created to track the detection of changes in coverage and land use. The Terra- I data allows users expect the analysis of USGS/NASA MODIS images (NDVI) and TRMM (rainfall) to predict changes due to human actions, in near real time. The data allow to do spatial analyses specialized in the sustainable use and conservation of natural resources and ecosystems. CIAT processed this data to provide land cover change maps to GEOSUR geoserver.

  • Credit
  • Terra-i is the result of a collaboration between the CIAT (Louis Reymondin, Andy Jarvis), The Nature Conservancy (Jerry Touval) The University of Applied Sciences of Western Switzerland (Andres Perez-Uribe) and King’s College London (Mark Mulligan). The methodology was mainly developed in collaboration with the University of Applied Sciences of Western Switzerland (HEIG-VD, based in Switzerland). In particular with Professor Andres Perez-Uribe and a group of students who worked on specific part of the methodology for their Master/Undergraduate thesis: Abson Sae-Tang, Julien Rebetez, Valentin Gaillard, Kevin Georgy The detections algorithms were described by Louis Reymondin, Andrew Jarvis, Andres Perez-Uribe, Jerry Touval, Karolina Argote, Julien Rebetez, Edward Guevara, Mark Mulligan (2012), A methodology for near real-time monitoring of habitat change at continental scales using MODIS-NDVI and TRMM.
