Cluster Analysis of Landsat Tm Data
نویسندگان
چکیده
Cluster analysis ~ystem by using Statistical Analysis System (SAS) is constructed. The analysis system is applied to Landsat TM data. The s:x spectral bands except t~e thermal band of TM data are used for analysis. Three hierarchical algorithms of cluster analysIs, \\:,ard method, a,:,erag~ lmkage, and centroid method, are prepared in the framework of SAS cluster. The results by three alg;of1thm~ are exammed m relation to classification. The classified map by Ward method is the most accurate among them, and IS practIcal. On the other hand, the others are almost same and incorrect.

A model-based approach for mapping rangelands covers using Landsat TM image data
Empirical models are important tools for relating field-measured biophysical variables to remotely sensed data. Regression analysis has been a popular empirical method of linking these two types of data to estimate variables such as biomass, percent vegetation canopy cover, and bare soil. This study was conducted in a semi-arid rangeland ecosystem of Qazvin province, Iran. This paper presents t...

متن کاملDerivation of Landsat 5 Tm Detector Relative Gain Models Using the Usgs Image Assessment System (ias)
Historical efforts to gather and utilize Landsat Thematic Mapper radiometric information from Earth images and the sensor internal calibration systems were typically manual in nature and hence limited in terms of data sampling and subsequent analysis. Multiple government agencies and private corporations operated the Landsat TM missions over their respective lifetimes resulting in a sparse spor...
متن کاملData Continuity of Earth Observing 1 ( EO - 1 ) Advanced Land Imager ( ALI ) and Landsat TM and ETM +
The National Aeronautics and Space Administration (NASA) Landsat program has been dedicated to sustaining data continuity over the 20-year period during which Landsat Thematic Mapper (TM) and Enhanced TM Plus (ETM+) sensors have been acquiring images of the earth's surface. In 2000, NASA launched the Earth Observing-1 (EO-1) Advanced Land Imager (ALI) to test new technology that could improve t...
متن کاملRadiometric cross-calibration of the Landsat-7 ETM+ and Landsat-5 TM sensors based on tandem data sets
Early in its mission, the Landsat-7 spacecraft was temporarily placed in a ‘‘tandem’’ orbit very close to that of the Landsat-5 spacecraft in order to facilitate the establishment of sensor calibration continuity between the Landsat-7 Enhanced Thematic Mapper Plus (ETM+) and Landsat-5 Thematic Mapper (TM) sensors. The key period for the tandem configuration was June 1–4, 1999, during which hund...
