Applying ArcGIS Online application to geological fieldwork provides an alternative way teach students. This brief report describes educational innovation for with the examine students’ learning experiences. In comparison traditional classrooms, this teaching method enables students more easily comprehend how structures and features connect through mapping area. observation indicates that can th...

Based on the current state of science and technology, computer based Spatial Decision Support Systems (SDSSs) can be used for modern management and planning purposes. To fulfil the requirements of being advanced comprehensive systems, such modern SDSSs provide access to individual data and computer models. They combine tools and analysis functions of Geographical Information Systems (GIS), Deci...

This article presents the conceptual design of a collaborative web-based Geographic Information System (GIS) for land use planning in which all parties including land use planners, applicants/developers, and community stakeholders can participate. The approach employs three-tier architecture built in a Java client-server environment, and consists of the ESRI ArcGIS 9.2® Server Advanced Edition ...

The uncertainty of modeling input will increase the simulation error, and this situation always happens in a model without user-friendly interface. WinVAST model, developed by the University of Virginia in 2003, treats an entire multi-catchment by a tree-view structure. Its extra computer programs can connect geographic information system (GIS). Model users can prepare all the necessary informa...

Remote sensing and GIS techniques were developed and evaluated to retrospectively analyze the impacts of the McNally Fire on air quality. The McNally Fire was a large wildfire over 54,700 ha (150,000 acres) in size that occurred in the Sequoia National Forest, California, 21 July through 26 August 2002. MODIS satellite images and NOAA pictures were used to digitize smoke plumes. Smoke plumes we...

When researchers are interested in multiple geographic datasets over similar geographic areas, it is oftentimes necessary to mosaic the digital images. The process becomes increasingly difficult as the images vary in projection, spatial resolution, and data representation. We first present a framework to describe this mosaicking process in a formal setting. We resolve the issues of varying proj...

Utility services are an important component of the physical structure of towns and there is a need for detailed information about the location and condition of their infrastructure. Acquiring data in the conventional way is time consuming and costly. The integration of GIS with electric utilities is tremendously improving the planning and operation of the system. GIS and GPS are also integrated...

PRO-GRADE is an ESRI ArcGIS 9.2 plug-in package that consists of two separate toolkits: (1) the pattern recognition organizer for geographic information system (PRO-GIS) and (2) the ground water recharge and discharge estimator for GIS (GRADE-GIS). PRO-GIS is a collection of several existing image-processing algorithms into one user interface to offer the flexibility to extract spatial patterns...
