Data Penginderaan Jauh adalah merupakan salah satu alternatif untuk mendapatkan informasi tentang suatu obyek dengan melakukan pengukuran dari jarak jauh tanpa menyentuh obyek. Aspek terpenting adalah dalam perolehan data (Data acusition atau collection) dan pengolahan atau analisis data (data processing atau analysis).
Alternatif yang digunakan adalah data Landsat-TM dan data JERS-1 SAR serta data GPS sebagai sarana untuk koreksi geometri. Untuk Koreksi data JERS-1 S AR sangat sulit karena tidak dapat mengenali obyek karena itu digunakan ...

Dalam penelitian ini penulis membuat program Pengenalan Obyek ( Object Recognition ) mulai dari obyek yang berupa image, hingga mendapatkan parameter-parametemya (ciri-cirinya) sampai pada proses pengenalannya dengan Neural Network. Untuk proses pengenalan obyek dengan Neural Network penulis menggunakan Multi-Layer Back Propagation Neural Network Simulator.
Persoalan yang paling penting dalam proses pengenalan obyek dua dimensi adalah pemilihan parameter (ciri) yang tidak.dipengaruhi oleh proses skala, rotasi dan translasi pada obyek berbentuk kontur (keliling garis tepi pada ...

Metode radar interferometri mempunyai kemampuan menghasilkan data model elevasi dijital (Digital Elevation Model - DEM). Beberapa penelitian mengenai ketelitian DEM data radar interferometri yang pernah dilakukan sebelumnya menunjukan hasil yang baik. Meskipun demikian penelitian ini di Indonesia, khususnya airborne radar interferometri belum pemah dilakukan.
Prinsip dari radar interferometri adalah mendapatkan korelasi antara beda fasa dengan posisi titik di permukaan bumi. Beda fasa gelombang radar diperhitungkan dari fasa yang terukur pada antena kesatu dan fasa yang terukur ...

Segmentation is basically a process of pixel classification, the picture is segmented into subsets by assigning the individual pixel to classes. In this case when segmentation by thresholding it have to do classifying the pixels into " dark" and "light" classes, in an attempt to distinguish dark object from their light background.
Similarly in edge detection pixels is classified into "edge" and "not edge" by thresholding the response of some difference operator that has high values ...

A two dimensional layer or cross section of a three dimensional object can be reconstructed by means of a large number of one dimensional projections through this layer. Reconstruction a two dimensional phantom from its one-dimensional projection has been accomplished in this thesis using the technique where the input projection data of CT X-Ray is simulated. The qualities of reconstructed phantom from the projections have shown a good result compared to the original image. This ...

STAR-1 synthetic aperture radar (SAR) imagery takes over portions of East Kalimantan. In the first part of this study, the basic theory of SAR was reviewed, begin by digital signal processing, and then range / azimuth resolution and the last is pulse compression. Specific applications like Frost Filter to reduce speckle caused by multiplicative white noise had been run by "FILTER.F77" program. The Frost filter seems not to give optimum results in this study area. ...

A model to contour hydrographic data was designed to determine the depth of water. Because uf sparse and random nature of the given data, we superimposed an optimally sized grid system on the region and assigned the known data at their corresponding grid points. Thon We used the principle of minimum curvature tn derive finite difference? equations that calculated the remaining grid points. We iterated these equations until a convergence criterion of 0.01 over the ...

Two multi-temporal as well as multi-sensor data of LANDSAT MSS (1979) and MOS (1991) were used for Mangrove Forest change detection in Tg. Karawang, West Java. About 13,986 hectare decrease of total volume of the Mangrove Forest were detected for 12 years from 1979 to 1991. Procedures for change detection of vegetated areas employed in this study were detected by post-classification differencing technique. Landsat MSS image was registered to MOS image after the extraction of ...

Aplikasi interferometri SAR pada data satelit masih sangat terbatas, karena belum dimungkinkan menempatkan dua sensor SAR (radar) pada satu satelit. Kendala teknis ini muncul akibat keterbatasan penyediaan sumber daya untuk mengoperasikan dua sensor secara simultan. Akihatnya implementasi interferometri terbatas pada interferometri dengan pengulangan orbit (repeat-orbit interferometric). Sementara interferometri pada data airborne SAR relatif lebih luas karena dapat dilakukan interferometri along-track maupun accros-track.
Implementasi interferometri SAR pada data airborne maupun spaceborne menuntut pemahaman tentang gelombang radar ...
