Remote sensing data with multispectral, multitemporal characteristics, advanced technology and wide coverage is an useful tool for monitoring land use changes generally and urban dynamics particularly. Taking the advantage of LANDSAT 7 ETM + data with the finest resolution of 12.5 m, visualized interpretation method and automatic classification were implemented in order to create a procedure of monitoring land use based on high resolution remote sensing images. Land use database is built to track the land use changes with land use planning by updating the land use data every year or 2, 3 years. Hence, WEBGIS technology integrated with the database will generate a monitoring tool effectively.
