The Shuttle Radar Topography Mission Digital Elevation Model as an alternative data source for deriving hydrological characteristics in lowland catchment — Rogożynek catchment case study This paper describes possibility of supplementing digital topography data needed for hydrologic modeling (WetSpa model) of lowland catchment with existing, freely available DEM data obtained from Shuttle Radar Topography Mission launched on February 11th, 2000. Rogożynek basin (Upper Biebrza) as case study is given. Authors compared three DEMs: topographic — TOPO DEM 20 (20 m resolution), radar — SRTM DEM 90 (90 m res.) and resampled radar — SRTM DEM 20 (20 m res.). There were several characteristics compared and analyzed like: relative height differences, slopes, generated river network and generated subwatersheds (subbasins).

Abstract. A suite of 42 geomorphometric parameters for each of 26 272 drainage basins larger than 100 km2 from the Hydrosheds Shuttle Radar Topography digital elevation model shows the global distribution of Strahler order for streams and drainage basins; the largest basins are order 9. Many common parameters depend both on the size of the basin, and the scale of the digital elevation model used for the computations. These drainage basins display the typical longitudinal stream profiles, but the major basins tend to be more convex than the smaller basins.

Abstract The TerraSAR-X add-on for Digital Elevation Measurement (TanDEM-X) mission launched in 2010 is another programme – after the Shuttle Radar Topography Mission (SRTM) in 2000 – that uses space-borne radar interferometry to build a global digital surface model. This article presents the accuracy assessment of the TanDEM-X intermediate Digital Elevation Model (IDEM) provided by the German Aerospace Center (DLR) under the project “Accuracy assessment of a Digital Elevation Model based on TanDEM-X data” for the southwestern territory of Poland. The study area included: open terrain, urban terrain and forested terrain. Based on a set of 17,498 reference points acquired by airborne laser scanning, the mean errors of average heights and standard deviations were calculated for areas with a terrain slope below 2 degrees, between 2 and 6 degrees and above 6 degrees. The absolute accuracy of the IDEM data for the analysed area, expressed as a root mean square error (Total RMSE), was 0.77 m.

Abstract. A suite of 42 morphometric parameters for each of 26 272 drainage basins larger than 100 km2 from the Hydrosheds Shuttle Radar Topography digital elevation model shows the global distribution of Strahler order for streams and drainage basins. At the scale of 15 arc s spacing (232 to 464 m) the largest basins are order 9. Many common parameters depend both on the size of the basin, and the scale of the digital elevation model used for the computations. These drainage basins display the typical longitudinal stream profiles, but the major basins tend to be generally more concave than the smaller basins.

Digital Elevation Model (DEM) is a source to produce contour map, slope, and aspect information, which is needed for other information such as disaster and water resources management. DEM can be generated by several methods. One of them is parallax calculations from stereoscopic data of optical sensor. Panchromatic Remote-Sensing Instrument for Stereo Mapping (PRISM) sensor from Advanced LAnd Observation Satellite (ALOS) satellite and advance space borne Thermal Emission and Reflection Radiometer (ASTER) sensor from Terra Satellite is Japanese optical satellite sensor which have abilityto produce stereoscopic data. This study showed DEM generations from PRISM (2.5 m spatial resolution) and ASTER (15m spatial resolution) stereoscopic data using image matching and collinear model based on Orthobase-pro software. The Generated DEM from each sensor was compared to the DEM from Shuttle Radar Topography Mission (SRTM) X-C band with 30 m spatial resolution. The dependent on the pixel size from the DEM produced were also discussed. The result showed that both DEMs have similiar elevation and distribution pattern to the referenced DEM, but DEM for PRISM had higher relative accuracy (RMSE is 6.5 m) and Smoother pattern comparing to DEM from ASTER (RMSE is 10.2 m) Keyword : ASTER, DEM, PRISM, SRTM, Stereoscopic satellite data

This study aims to estimate the accuracy of digital elevation models (DEM) which are created with exploitation of open source Google Earth data and comparing with the widely available DEM datasets, Shuttle Radar Topography Mission (SRTM), version 3, and Advanced Spaceborne Thermal Emission and Reflection Radiometer Global Digital Elevation Model (ASTER GDEM), version 2. The GPS technique is used in this study to produce digital elevation raster with a high level of accuracy, as reference raster, compared to the DEM datasets. Baghdad University, Al Jadriya campus, is selected as a study area. Besides, 151 reference points were created within the study area to evaluate the results based on the values of RMS.Furthermore, the Geographic Information System (GIS) was utilized to analyze, imagine and interpolate data in this study.

ABSTRAKInformasi mengenai debit puncak sangat penting dalam perencanaan pembangunan infrastruktur. Debit puncak dapat diprediksi menggunakan data dari alat pengukur tinggi muka air yang di pasang di outlet Daerah Aliran Sungai (DAS). Namun demikian, tidak semua DAS memiliki alat tersebut, terutama yang berada pada daerah dengan tingkat aksesibilitas rendah. Teknologi penginderaan jauh dapat menggantikan cara tersebut dalam menyediakan data dan informasi sumberdaya alam maupun pemantauan lingkungan. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh perubahan penutupan lahan terhadap debit puncak di Sub DAS Jelap. Sub DAS Jelap merupakan bagian dari DAS Kapuas yang berada di Kabupaten Sintang, Propinsi Kalimantan Barat. Data curah hujan diperoleh dari stasiun pengamatan curah hujan Bandara Susilo. Debit puncak dihitung menggunakan metode Rational dengan memanfaatkan data satelit penginderaan jauh berupa Digital Elevation Model/ Shuttle Radar Topography Mission (DEM/ SRTM). Selama 1990-2016, hutan lahan kering sekunder dan hutan rawa sekunder mengalami penurunan seluas 1298 ha dan 338 ha, sedangkan semak belukar, semak belukar rawa, pertanian lahan kering campur semak, perkebunan dan area pertambangan mengalami peningkatan sebesar 78 ha, 102 ha, 814 ha, 640 ha, dan 2 ha. Perubahan penutupan lahan tersebut telah meningkatkan koefisien runoff dengan rata-rata peningkatan sebesar 0,14%. Dengan luas daerah terbangun kurang dari 1%, debit puncak yang dihasilkan berdasarkan analisis spasial memiliki pola yang hampir sama dengan fluktuasi curah hujan maksimum. Hal ini menunjukkan bahwa dibandingkan faktor lainnya, curah hujan maksimum merupakan faktor yang sangat menentukan nilai debit puncak di Sub DAS Jelap.Kata kunci: Penutupan lahan, curah hujan, debit puncak, Jelap, SintangEnglish title: Analysis of land cover change and its impact on peak discharge in Jelap Sub-Watershed, Sintang DistrictABSTRACTInformation on peak discharge is crucial in infrastructure development planning. Peak discharge could be predicted using data from water level gauges which installed at the watershed outlet. However, not all of the watersheds have such tools, especially those in areas with low accessibility levels. Remote sensing technology could replace such tools in providing data and information of natural resources as well as environmental monitoring. The objective of this research was to analyze the land cover change and its impact on peak discharge at Jelap Sub-Watershed. Jelap Sub-Watershed is part of Kapuas Watershed located in Sintang District, West Kalimantan Province. The rainfall data were collected from Susilo Airport Rainfall Station. Peak discharge was calculated using a rational method by utilizing remote sensing satellite data in the form of Digital Elevation Model/ Shuttle Radar Topography Mission (DEM/ SRTM). Throughout 1990-2016, the area of secondary dry land forest and secondary swamp forest declined by 1298 ha and 338 ha, while shrubs, swamp shrubs, mixed dry land agriculture, plantations, and mining areas increased by 78 ha, 102 ha, 814 ha, 640 ha, and 2 ha. The change in land cover has increased the runoff coefficient with 0,14% average increment. With built area less than 1%, the peak discharge generated spatially had a similar pattern with the fluctuation of maximum rainfall. Compared to other factors, the maximum rainfall was the most decisive factor to determine peak discharge in Jelap Sub-Watershed.Keywords: Landcover, Rainfall, Peak discharge, Jelap, SintangCitation: Auliyani, D.
