Based on the interpretation of the Landsat-TM data which was with 82 digital images taken in 1990 and 2000 respectively,the landscape structure and its changes of the grassland in the Northern Tibet were studied to reveal the land use change by analyzing the indices of patch-size,spatial pattern and other parameters commonly used in landscape ecology.

Based on the interpretation of the Landsat-TM data (with two digital images taken in 1989 and 2000, respectively), the landscape structure was studied by analyzing patch-size, spatial pattern, and other index to show the changing feature of landscape pattern.

The relationship between soil erosion and vegetation coverage on the basic of TM image interpretation in Nanchuan City,Chongqing;

Extracting Gold Mineralized Information Directly from TM Image;

A study on automatic extraction model for the residential area of cities in the Northeast Plain from TM image;

To study urban space shape through TM images,gain urban evolution rule,and use the research results to serve for urban planning,construction and management have become a new RS application field.

In this paper, a new technique to the problem of road recognition in TM images is presented.
