A PLANIMETRICALLY ACCURATE SPOT IMAGE MOSAIC OF BUTON ISLAND, SULAWESI, INDONESIA

A new map of Buton Island has planimetric sea-level accuracy of about 50 meters. This map is based on a series of panchromatic images from the French SPOT satellite and Doppler ground control. A comparison of the coastline positions shows discrepancies as large as two kilometres between the best existing maps and this new SPOT map. This new map has proven very useful both for planning seismic and other logistics opearations as well as for field use. The methods described herein may prove useful in other frontier areas of exploration. Most of Buton Island is covered by three nominal SPOT scenes. However, during a year's time, no cloud-free scenes of Buton were acquired by SPOT. Conoco acquired eight SPOT scenes with complementary cloud cover. Each scene was geometrically corrected and then mosaicked to generate a final SPOT image mosaic of Buton that was nearly free of clouds. Two different digital methods were chosen to combine images. One method consisted of cutting and pasting cloud-free images while another method compared data on a pixel by pixel basis and attempted to choose the cloud free pixel.
