GRAM++ is a collection of software packages for geographic information system (GIS) applications, developed indigenously at the Centre of Studies in Resources Engineering (CSRE), Indian Institute of Technology (IIT), Bombay. This software is now being used for a number of GIS applications that assist decision makers in taking informed decisions. Some of these applications include simulation of the spatial impact of raising height of dam and assessment of the costs and benefits; identifying sites suitable for inland aquaculture and validation with existing sites; developing resource profiles and computation of human development indices for prioritized development; land suitability analysis for agriculture applications.

The Pocket PC has become more popular in market because of the advantages of its small size and convenience for regular customers. Pocket PC is a mobile device so that we can receive the benefits of shared data over a wireless network. Enabling us to transmit data to a central location, simply messaging from one point to the next, its ability to share information across a wireless platform is becoming central to our communication needs. However, using Windows CE - an embedded operating system, as well as being designed for mobile users, there are many limitations to memory and speed of arithmetic operations on Pocket PC. As a result, developers have to deal with many difficulties in managing information storage when developing applications, especially Geography Information System (GIS) applications. In this paper, we propose some efficient methods to store GIS data and to increase the speed of displaying maps in GIS applications developed on Pocket PC and Windows CE 3.0.

One of recent trends in Web-based GIS is the system development using FOSS (Free and Open Source Software). Open Source software is independent from the technologies of commercial software and can increase the reusability and extensibility of existing systems. In this study, we developed a Web-based GIS for interactive visualization of geographic information using Google Earth and spatial DBMS(database management system). Google Earth Plug-in and Google Earth API(application programming interface) were used to embed a geo-browser in the Web browser. In order to integrate the Google Earth with a spatial DBMS, we implemented a KML(Keyhole Markup Language) generator for transmitting server-side data according to user's query and converting the data to a variety of KML for geovisualization on the Web. Our prototype system was tested using time-series of LAI(leaf area index), forest map, and crop yield statistics. The demonstration included the geovisualization of raster and vector data in the form of an animated map and a 3-D choropleth map. We anticipate our KML generator and system framework will be extended to a more comprehensive geospatial analysis system on the Web.

The purpose of this research is to support decision making of emergency rescue system with GIS which selects landing point of emergency rescue for emergency situation on mountains and dropping point when landing is impossible. The area of research was limited to Pocheon-si, Gyeonggi-do. The results were divided into two values; landing point of helicopter on mountains and dropping point. Digital map, forest type map and forest soil map were utilized as fundamental data. Factors of landing point were slope, topographical characteristics, vegetation characteristics and area of helicopter landing point by helicopter data. And, for dropping point, slope and vegetation characteristics were divided as factors and GIS intersect function was utilized for the analysis. But, this research was conducted by excluding factor values of wind direction, wind velocity, etc. In the future, it's necessary to improve effectiveness of the analysis more by making a connection with Meteorological Agency DB.

A flood loss estimation toolbox was developed within GIS software. This toolbox is for anyone who is interested in the flood loss estimation, and uses data accessible to public. In particular, the loss estimation framework in the toolbox is distinct in that the inventory items are individually dealt with. The toolbox was applied to estimate the economic loss from a levee failure event in 2002. The estimated loss was a little larger than the reported value. The difference is probably due to the asset values and the damage functions for each inventory item, which have to be updated.

Facilities Management(FM) System is widely spread GIS applications introduced in local governments. Over the last few years many local governments in Korea have developed facilities management systems, especially for underground facilities(drinking water and sewerage) and road management systems. The concept of Standardized Facilities Management Software(SFMS) was developed to minimize the duplication of efforts in local governments. Recently local governments try to change their direction to Urban Information Systems(UIS) which can comprehensively manage their information project carried out by each sector. Therefore this study suggests a method for introducing a Standardized Facilities Management Software to help constructing urban information system. This method is expected to prevent double investment, reduce project time, minimize the risk of project failure, and activate information projects.

GIS have expanded the use-range to the various application area with the advantage of interface environment, the various geographical operation. topological analysis by the friendly user. Early GIS software was developed as monolithic tool in which all functions packed in the same software. But, these GIS software have the problems of the high cost of constructing system, closely related system architecture and the reusability. And there is a lack of interoperability between them because most of them have their own unique data format according to their practical application fields. So Component is a unit that it is cohesive software package which is able to be developed and arranged independently and connected with another component for necessary system composition. In this paper, we analyze the requirements for component design and component specifications based on the extracted components. Commonly used to extract components from the requirements of the GPS component-based development process is presented. These components extracted by the process can be used to assemble components only. In particular, applications for developers to add features specific case without affecting the other components that can be modify the component.

In recent, interests regarding open source software for geo-spatial processing are increasing. Open source remote sensing (OSRS) is regarded as one of the progressing and advanced fields in remote sensing. Nevertheless, analyses or application cases regarding OSRS are not enough for general uses or references. In this study, three kinds of OSRS software in consideration of international popularity, types of functionalities, and development environments are taken into account: OSSIM, Opticks, and ORFEO Toolbox (OTB). First, functional comparison with respect to these is carried out on the level of the preliminary survey. According to this investigation, OTB is chosen as the most applicable OSRS software in this study. Running on OTB, NIX format importing module and database connecting module are implemented for widely general uses and further application. As for an example case, airborne image of NIX format is used to region growing segmentation algorithm in OTB, and then the results are stored and retrieved in PostGIS database to test implemented modules. Conclusively, local customization and algorithm development using OSRS software are necessary to build on-demand applications from the developers' viewpoint.
