Cadastral System

The cadastral system in Nepal is developing continuously with gradual speed. Cadastralsurvey started with chain survey and in due course of time, plane table survey was adopted for the survey in spite of its limitations in accuracy and time. Currently, total station has been practiced in few municipalities for this purpose. The paper focuses on the probability of modern data handling technology; Total station, Global Positioning System (GPS), Participatory GIS and Remote Sensing as the appropriate technology for the improvement of existing cadastral system of the country. Current situation of the cadastral system and the technology used, its shortcomings and the suitability of the proposed data handling technology are discussed in the paper.

Total Station and Global Positioning System (GPS) are two instruments used to fix position on the earth. The total station employs electro-optical distance meter method, emitting laser beams to a target and detecting light reflected off it by measuring the deviation of the wavelength of the reflected light. Global Positioning System (GPS) is a space-based satellite for rapid position determination, its’ receiver calculates its position by precisely turning the signal sent by GPS satellite high above the earth. The study aims at the assessment of the two instruments: GPS and Total Station. To achieve this aim, two surveys were performed on the same parcel of land using the two instruments. In the first part of the survey, a closed-loop traverse was performed around a chosen parcel of land using a calibrated total station. The station determined only coordinates of points from where bearings and distances were extracted. Thereafter, DGPS equipment was then used to perform a similar survey as the total station. In this case, visible satellites were used to determine the coordinates of all the stations. The results of the two methods present the distances, bearings, and coordinates. The difference between each of the results was also analyzed. Thus the maximum average difference in distance of 5mm occurred throughout the chainage and maximum differences in the coordinate of 12mm Easting and 9mm Northing were found where there are tree covers. However, the study shows that even though the two instruments are good tools for positioning, each exhibited it’s own accuracy, efficiency, advantages and disadvantage.

Diferencias en elevación en un juego de 12 puntos diferentes fue determinado utilizando dos técnicas diferentes: estacional total y un sistema de GPS diferencial (utilizando tres receptores con tiempos de ocupación de 90 minutos por estación). Una comparativa entre los dos juegos de valores de la elevación dan una diferencia que varía de dos a 36 mm para una línea base de máximo 2,420 metros de distancia. Estos resultados demuestran que los levantamientos utilizando el sistema GPS diferencial pueden ser utilizados para realizar nivelaciones utilizando dicha técnica.

The Disaster Monitoring Constellation (DMC) is an international Earth observation programme to provide a rapid global remote sensing service for the monitoring and mitigation of natural and man-made disasters. Although the Global Positioning System (GPS) was originally designed for terrestrial and air applications, satellite operations have benefited greatly from the use of on-board GPS receivers. This paper describes the GPS receiver operations on the DMC satellites, performance analysis, lessons learned, and upgrades planned for the future.

Wilayah perkotaan di Indonesia memiliki karakteristik yang sama dengan wilayah perkotaan di negara-negara berkembang. Beberapa karakteristik tersebut seperti: (1) penurunan fungsi alam dengan berkurangnya ruang hijau atau vegetasi, (2) penumpukan bangunan beratap pada wilayah yang dekat dengan akses transportasi, industri dan pasar, (3) lokasi pemukiman pada zona yang berbahaya karena dekat dengan terminal, sepanjang aliran sungai, sepanjang jalur rel kereta api, dan tempat pembuangan sampah akhir. Keterkaitan antara nilai indeks kemiskinan dengan morfologi fisik dan vegetasi suatu wilayah dapat diketahui dengan pemanfaatan teknologi remote sensing (RS). Keakuratan analisis pemukiman miskin dengan teknologi RS bergantung pada kualitas citra satelit Very High Resolution (VHR) dan kelengkapan dataset Sistem Informasi Geografis (SIG). Teknologi Geospasial yang terintegrasi seperti RS, SIG, dan Global Positioning System (GPS) dapat berkontribusi secara interaktif dalam penilaian, pemahaman dan pemetaan untuk memecahkan masalah pemukiman penduduk yang kompleks di Indonesia. Urban areas in Indonesia have the same characteristics with urban areas in developing countries. Some characteristics such as: (1) decreased of the function of nature with the reduced the number of natural green space or vegetation, (2) accumulation of roofed buildings in the area close to transportation access, industry and market, (3) the location of housing in the dangerous zone as close to the terminal, along the river side, along the railway lines, and the final waste disposal sites. The linkage between poverty index values with the physical morphology and vegetation of an area can be identified by the use of technology and remote sensing (RS). The accuracy of the analysis of poor housing with RS technology relies on the image quality of Very High Resolution (VHR) satellite and the completeness of the dataset Geographic Information Systems (GIS). Geo-spatial technologies are integrated as RS, GIS, and Global Positioning System (GPS) can contribute interactively in the assessment, understanding and mapping to solve the complex problem of residential in Indonesia.

Dengan berkembangnya teknologi dalam survei pemetaan seperti halnya penggunaan GPS Geodetik, maka penerapan dari teknologi untuk kebutuhan survei perlu memperhatikan faktor-faktor tertentu seperti ketersediaan alat, sumber daya manusia hingga kondisi lapangan. GPS atau biasa dikenal dengan Global Positioning System merupakan teknologi/alat atau sistem yang memberikan informasi berupa posisi kepada pengguna secara global dan real-time di permukaan bumi yang berbasis data satelit. Dengan teknologi tersebut diperoleh ketelitian yang tinggi dengan waktu yang singkat dalam penentuan sebuah posisi. Penelitian ini bertujuan untuk mengetahui ketelitian hasil pengukuran luas bidang tanah menggunakan teknologi GPS RTK-Radio dan GPS RTK NTRIP sebagai sikap pengambilan keputusan. Penelitian dilakukan terhadap daerah dengan obstruksi dan tanpa obstruksi fisik. Nantinya, dari penelitian ini diperoleh nilai-nilai koordinat (X,Y) dari GPS RTK-NTRIP maupun RTK-Radio, yang kemudian dihitung luasnya dan dibandingkan dari hasil pengukuran menggunakan ETS (Electronic Total Station) terhadap standar ketelitian luas dari BPN. Hasil perhitungan selisih luas lahan baik dengan obstruksi secara fisik maupun tidak, masih masuk dalam toleransi ketelitian BPN, walaupun untuk lahan yang terdapat obstruksi fisik memiliki selisih antara pengukuran menggunakan GPS dan ETS yang cukup besar yaitu hampir mencapai 5 m2.
