The Forest fire during May 6-June 4, 1987 in Northeastern China burned 1.14 million hectares of forest and nearly 25 million cubic meters of timber. Landsat (5 and 7) and radar data (ERS and JERS-1) in combination with field measurements, were analyzed in terms of forest destruction and recovery and the results were evaluated. Temporal Landsat data enabled the identification of burned regions and the characterization of forest recovery, but sensitivity after 10 years was gradually lost. While the 1993 (and later) C-band SAR data from ERS cannot identify the fire scars, the 1997 JERS-1 L-band data can be used to characterize the burned area.

Monitoring forest dynamics using multi-sensor data in Northeastern China

Guoqing Sun David R. Williams Xiwu Zhan Zengyuan Li J. G. Masek

To monitor the dynamics of the forests in the vast Northeastern China region, we are developing an operational forest monitoring system using satellite remote sensing data. The major components of this system will include both standard and enhanced methodologies for forest cover mapping and change detection within a geographic information system (GIS) database. To rapidly assess forest conditions over the large geographical expanses in Northeast China, Moderate Resolution Imaging Spectroradiometer (MODIS) data are first used to detect areas of change at the macro scale. Once identified, fine resolution Landsat 7 ETM+, and SAR data, are used to generate fine resolution, micro-scale forest maps to characterize the nature/cause of the change(s). This paper describes the project and presents preliminary results in forest classification and change detection in this region.
