"ABSTRACTA Line object extraction from satellite imagery is presented in this thesis. The extraction technique can be significant to both application and development of digital remote sensing methodology the analysis proceeds from satellite imagery to the detailed analysis of specific regions. Smoothing, Laplacian Transform, Line detection and Threshold techniques are used to extract a line object from satellite imagery. This extraction technique may eventually be extended to recognize different patterns for examples, rivers, runway or highway because there are many kind of linear feature. The algorithms for locating linear features are of general interest. A data from National Institute for Aeronautic and Space (LAPAN) was used which cover portions of Cengkareng and Jakarta Area. Its found that result will always contain a significant amount of noise and we can get information about the object early. "

"LAPAN is currently developing LAPAN - 2 AND LAPAN-ORARI satellites which are planned to be launched in 2011. Both satellites will be placed in equatorial orbit at 650 km height above the earth surface with 8 degrees inclination. The analytical resutl by using the simulation model shows that by implementing 8 degree inclination, several LAPAN ground stations which are located in the equatorial line such as Bukittinggi and Biak ground station have longer duration to access the satellite compared with those which are located quite far from equator line such as Rumpin ground station. Besides, by placing both satellites in the 8 degree inclination, the LAPAN's ground station will be abble to access the satellites between 10 until 14 times per day. The height of the access ability from the ground station to the satellite will provide big advantages because the satellite can be used to monitor the earth surface more often. "
