PENYEDIAAN DATA DAN INFORMASI DARI CITRA SATELIT QUICKBIRD UNTUK PENGELOLAAN PAJAK BUMI DAN BANGUNAN PERKOTAAN = Utilizing Data and Information from QuickBird Satellite Imaging for Managing Land and Building Taxes in ...

The Directorate General of Taxes, in particular the Directorate of PBB and BPHTB (Land and Building Tax, and Acquisition Duty Land and Building Right) Directorate has been using QuickBird Pankromatik Standard Imagery for gathering data of potentially taxed objects in several areas. The line-map as a result of an image interpretation was used to determine area, and to assess the tax imposed on land and building of the area. The general implementation stages outline in this research included two stages, namely imagery processing stage and analyst stage. The image enhancement was done in the image processing stage using the contrast stretching and histogram equalization algorithms. In order to conduct testing on the difference in the measurement of areas between maps based on digitized data from satellite imaging and maps of PBB block map using terrestrial measurement yielded an area tolerance of 10 % (in accordance Surat Keputusan Dirjen Pajak Nomor : KEP-533/PJ/2000). Measurement of interpretation accuracy was conducted using the Short method. The result has shown that accuracy of object/building interpretation using satellite imaging-based data is quite high, as shown by the result of 1002 objects digitized on QuickBird Panchromatic Standard Imagery. The percentage of accuracy of the whole study area is 96.31 %. Tests on the differences of area
