As the second largest city in Indonesia, Surabaya city with a population of more than 3 million people that has a function as a center of business, commerce, industry, and education in Eastern Indonesia into a strong attraction for the urban thereby providing an increasing number of residents each year. Based on Landsat TM and Landsat 7 ETM+ Surabaya city has an area of 372.667 pixels or 335.4Km ², physically experiencing very rapid growth of the city for almost 20 years (1990-2009) 55.5% and 13.6% of the total area of the city. Most shape of growing cities in Indonesia, where are always faced with problems with the shrinking of the green area. Through remote sensing and GIS technologies, carried out the stages of processing of Landsat TM (1990) and Landsat 7 ETM years 2000-2009, where Landsat imagery in 2007 and 2009 should be processed first, for the missing data can be improved, needs to be done charging referred to as the filling scan gap. Performed supervised classification using Maximum Likelihood method and the overlay with GIS technology from the year 1990-2009. The study shows a green area with land use: vegetation and mangrove from the years 1990-2009 Surabaya shrinkage is very rapid, from 48% (1990) shrank 37.1% to just 10.9% in 2009, when calculated on the basis of extensive due 335.4Km ² siltation thereby increasing the land area on the east side of the city of Surabaya at 7.1Km².
Key words: land area, Surabaya city, temporal multispectral imagery, image difference
