Hydrology Modelling-Based Biopore Infiltration Holes (BIH) Determination as River Flood Disaster Mitigation in Sewu Village, Surakarta, Central Java, Indonesia

Jurnal Geografi, 2020
Sewu Village is annually experience by river flooding. The application of Biopore Infiltration Holes (BIH) is one of the measures to reduce river flood disaster risk. This research was aimed to determine the proper location of the BIH. Hydrology tools by

Spectral filtering as a method of visualising and removing striped artefacts in digital elevation data [PDF]

, 2008
Spectral filtering was compared with traditional mean spatial filters to assess their ability to identify and remove striped artefacts in digital elevation data. The techniques were applied to two datasets: a 100 m contour derived digital elevation model

MORPHOLOGICAL FILLING OF DIGITAL ELEVATION MODELS [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Abstract. In this paper a new approach for a more detailed post processing and filling of digital elevation models (DEMs) in urban areas is presented. To reach the required specifications in a first step the errors in digital surface models (DSMs) generated by dense stereo algorithms are analyzed and methods for detection and classification of the ...

Pre-late Devensian high-arctic marine deposits in SW Scotland [PDF]

, 2010
We present new interpretations of Digital Elevation Model (DEM) data and marine fossils collected from three sites on the Rhins of Galloway which, contrary to recent proposals, suggest that the landforms and deposits of the region do not represent ...

InSAR observations of ice elevation and velocity fluctuations at the Flade Isblink ice cap, eastern North Greenland [PDF]

, 2010
The 8500 km(2) Flade Isblink ice cap (FIIC) (81 degrees 15'N, 15 degrees 0'W) is the largest ice cap in Greenland. We use repeat-pass interferometric synthetic aperture radar (InSAR) techniques to investigate the form and flow of the FIIC.
