Abstract

In recent decades, Remote sensing data becomes one of the basic information for generating of base maps and different applications in geomatics. In fact, it is providing very useful for a board range of environmental applications such as surveying, agriculture, geography, meteorology, hydrology, transportation, urban planning, control analysis, landscape planning and etc. Especially in order to generation base maps, the Satellites data has a great role and it is now widely applied on collecting and processing data. For reach to this purpose, we had been used Indian satellite imageries such as the IRS-P5 and the IRS-P6 satellite data which have been belonged to Indian Space Research Organization (ISRO). The P5 (Cartosat-I) satellite was launched on May 5, 2005 into circular sun synchronous orbit which it is equipped with two panchromatic cameras capable of simultaneous acquiring images of 2.5 meters spatial resolution. Also the IRS-P6 (Resourcesat-I) was launched on October 17, 2003 which has three sensor includes LISS III, LISS IV and AWIFS. The LISS IV sensor of this satellite has the spatial resolution 5.8 m with enhanced spectral resolution. It consists of three spectral bands in the green, red and near infrared regions of the electromagnetic spectrum. In this investigation we had been developed a method for generating of base maps in middle scale, such as 1:15000 ratio scale and an attempt has been made to evaluate the information content available with merging data consist of the IRS-P5 and MX mode image from IRS-P6 satellite imageries. The results have shown its capability in solving of generation base maps with IRS satellite data and we found that merging these data is very suitable for identification all of the features in the base maps in different categories.
