We provide a system to facilitate such decision making that blends traditional remote sensing with interactive techniques of exploratory spatial data analysis. Our system, 'mapping weathering forms in three-dimensional (3D)' (MapWeF) uses a 3D laser scanning device for sub-centimetre data collection from in situ rock surfaces. After image and digital surface model processing, key rock weathering forms are highlighted through classification. Supervised classification builds training classes as a user probes known weathering forms. Guided by these training classes, the user then interactively brushes and assembles pixels from scatter plots until the user is confident that all manifestations of a particular weathering form have been mapped. The purpose of MapWeF is to construct detailed maps that highlight regions of decay on rock art panels. These maps can help rock art conservators take action on panels in need of urgent preservation or remediation.

Identification and analysis of groundwater potential zones in Ken-Betwa river linking area using remote sensing and geographic information system / R. Avtar in Geocarto international, vol 25 n° 5 (August 2010)

Various themes of information such as geomorphology, land use/land cover, lineament extracted from digital processing of Landsat (ETM+) satellite data of the year 2005 and drainage map were extracted from survey of India topographic sheets, and elevation, slope data were generated from shuttle radar topography mission (SRTM) digital elevation model (DEM). These themes were overlaid to generate groundwater potential zonation (GWPZ) map of the area. The final map of the area shows different zones of groundwater prospects, viz., good (5.22% of the area), moderate (65.83% of the area) poor (15.31% of the area) and very poor (13.64% of area).

Application of remote sensing and geographic information system in change detection of the Netravati and Gurpur river channels, Karnataka, India / A. Kumar in Geocarto international, vol 25 n° 5 (August 2010)  

Public [article]  inGeocarto international > vol 25 n° 5 (August 2010) . - pp 397 - 425 Titre : Application of remote sensing and geographic information system in change detection of the Netravati and Gurpur river channels, Karnataka, India Type de document : Article/Communication Auteurs : A. Kumar, Auteur ; K. Jayappa, Auteur ; B. Deepika, Auteur Année de publication : 2010 Article en page(s) : pp 397 - 425 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Applications de télédétection [Termes IGN] cours d'eau [Termes IGN] détection de changement [Termes IGN] image IRS-LISS [Termes IGN] Inde [Termes IGN] séisme [Termes IGN] système d'information géographique [Termes IGN] tectonique Résumé : (Auteur) The Netravati and Gurpur (N-G) river basins are tectonically active due to a number of seismically active faults/lineaments and their proximity to Mulki-Pulicat Lake axis. The gradient of the river channels has gradually reduced (after ?10 km from their origin) and has forced the rivers to flow slowly in meandering and zigzag paths. The nature and intensity of meanders are governed by geological and tectonic conditions of the river basins. Significant changes in river channels, between the years 1910 and 2005, have been detected in three blocks - Block-I (Netravati) and Blocks-II and III (Gurpur) - and studied in detail by comparing topographic maps with Indian Remote Sensing Satellite, LISS-III images through GIS techniques. The block-wise qualitative and quantitative changes of these channels indicate that they are narrowed and migrate towards south due to neotectonic activities, formation of braided islands, variation in flow intensity and anthropogenic interventions like construction of vented dams and sand mining.
