Hydrological components in a river basin can get adversely affected by climate change in coming future. Manipur River basin lies in the extreme northeast region of India nestled in the lesser Himalayan ranges and it is under severe pressure from anthropogenic and natural factors. Basin is un-gauged as it lies in remote location and suffering from large data scarcity. This paper explores the imp...

Title of Document: SEMANTIC INTEGRATION OF GEOSPATIAL CONCEPTS – A STUDY OF LAND USE LAND COVER CLASSIFICATION SYSTEMS Hua Wei, Ph. D., 2011 Directed By: Professor John R. G. Townshend Department of Geography University of Maryland, College Park In GI Science, one of the most important interoperability issues relates to land use and land cover (LULC) data, because it is a key to the evaluation ...

Located in northwestern Botswana and fed by the Okavango River originating in Angola's western highlands, the Okavango Delta is the world’s largest inland delta. The floodwaters require approximately nine months to flow from the source to the bottom of the Delta due to the extremely low topographic relief. During the peak of flooding, the delta’s area can expand to over 16,000 square kilometers...

This study uses a spatially-explicit land-use/land-cover (LULC) modeling approach to model and map the future (2016–2030) LULC of the area surrounding the Laguna de Bay of Philippines under three different scenarios: ‘business-as-usual’, ‘compact development’, and ‘high sprawl’ scenarios. The Laguna de Bay is the largest lake in the Philippines and an important natural resource for the populati...

0099-1112/07/7309–1029/$3.00/0 © 2007 American Society for Photogrammetry and Remote Sensing Abstract This study established spectral matching techniques (SMTs) to determine land-use and land-cover (LULC) and irrigated area classes from historical time-series (HTS-LULC) AVHRR 0.1-degree pathfinder satellite sensor data. The approach for HTS-LULC mapping and characterization was to develop “targ...

Landuse vector data generalisation is to derive a new landuse dataset or map from an initial dataset by removing the minor details. The generalised results should delineate the dominant landuse characteristics of important landuse types in a reduced map space or a theme-specific application. The generalisation process are guided and controlled by a set of generalisation rules serving for the re...
