A GIS Based Tool to Digitize Polygon and Line Segments of a Black and White Map
Abstract: In this paper a GIS based tool has been proposed to digitize polygon and line objects throughefficient usage of RGB values of the segments of raster maps. For digitization of polygon,initially a closed loop is drawn inside the polygon segment. Beginning from the initial point ofthe closed loop, eight connected pixels calculation is incorporated to obtain the pointsexisting in between the loop and the actual boundary. The points which exist …

Soil Erosion Assessment and Its Effect on Sustainability for a Mountainous Watershed using Remote Sensing and GIS
Abstract: Normal 0 false false false EN-US X-NONE AR-SA Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Soil erosion is an important social and economic problem, and an essential factor in assessing health and function of ecosystem. Soil-erosion control requires a quantitative evaluation of potential soil erosion on a specific location. The revised universal soil loss equation (RUSLE), remote sensing, and …

Multi-sample Real-time Ray Tracing with Adaptive Temporal Anti-aliasing
Abstract: Path tracing gives the opportunity to render scenes with high quantity of not only point lights but as well as area lights; these could be then sampled and shadows can be generated by ray tracing, even without the use of any shadow maps or using any other raster scan technique that cannot work with area lights in large number. This gives an opportunity for an algorithm that keeps structure information …

Web Mapping Comparison of Open Layers Map and Google Map: A Web GIS based Big Spatial Data Approach
Abstract: Big data sharing and manipulation of geospatial data such a GIS web-based system has become a challenge. Due to the rapid development technology in web based geographical information systems, the uses of web based geospatial application, effective utilization and representation varies from Geo-spatial capabilities and functionalities. In this paper, a web GIS framework was explored to provide a practical solution for the display and manipulations of geospatial data, visualization of …
