LBA-ECO LC-09 Land Cover Transitions Maps for Study Sites in Para, Brazil: 1970-2001

Get Data
Revision date: June 20, 2012

Summary:

This data set includes classified land cover transition maps at 30-m resolution derived from Landsat TM, MSS, ETM+ imagery and aerial photos of Altamira, Santarem, and Ponta de Pedras, in the state of Para, Brazil. The Landsat images were classified into several types of land use (e.g., forest, secondary succession, pasture, annual crops, perennial crops, and water) and subjected to change detection analysis to create transition matrices of land cover change. Dates of acquired images represent the most cloud-free image retrievals from 1970-2001 for each site and are therefore not continuous. There are 3 GeoTIFF files (.tif) with this data set.

3. Data Application and Derivation:

Data to be used in spatial analysis of land use and land cover change.

4. Quality Assessment:

Data were georeferenced to previously rectified images with low RMS error (<1.0 m).

Classifications were produced with low errors of omission/commission (at time of metadata creation, these data were unavailable).

5. Data Acquisition Materials and Methods:

Study Sites

Land cover types were identified in classified Landsat TM, MSS, ETM+ images  and aerial photos of Altamira, Santarem, and Ponta de Pedras, in the state of Para, Brazil.

Methods

Original imagery was acquired from the following:

Dates of acquired images represent the most cloud-free image retrievals from 1970-2001 and are therefore not continuous.

Bands were combined (layer-stack) and registered to UTM using ERDAS Imagine (Leica Geosystems, St. Gallen, Switzerland) (version unknown at the time of metadata creation). Images were georeferenced to previously rectified images using ERDAS Imagine. Radiometric and atmospheric corrections were done according to methods described by Green et al. (2005).

Data have been rectified and subset unless otherwise noted. Individual images were classified into several types of land use (e.g., forest, secondary succession, pasture, annual crops, perennial crops, and water).

These classified images were used in change detection analysis to create transition matrices of land cover change. Classified images were developed by first running an unsupervised ISODATA classification, and editing the class names based on image interpretation, AOIs, spectral signatures, field notes and maps, and previous classification, using Erdas IMAGINE. Classified images were then used in a change detection analysis, using Erdas IMAGINE.

Data were originally in the Imagine file format (.img), but exported to TIF (.tif) using ERDAS Imagine 8.7.
