HydroGIS Tool Structure : Neogeography Application Model

Abstract

The basic two interesting areas of the GIS are community based GIS application developments and complex process automations. The HydroGIS tool development laid on the complex process automation research side as it based on the complex hydrological models. The community based GIS application or Neogeographic application is the most used GIS applications which frequently upload spatial information such as hotels, shops etc. by the general public, today. Therefore, always a large amount of spatial data is generated effortlessly, but due to credibility and accuracy issues, these data are in a lower suitability to be used in complex GIS processes. The present work attempted to develop a model to verify and use of such for complex GIS process. The proposed model consists three sub modules namely Presentation, GIS and Confirmation Modules. Basically the presentation module described about the user-side interface and its behaviour. The GIS module is the complex GIS Process Automation, which is totally depend on the individual GIS model used in processing. The most interest part of the model is Confirmation Module, which purifies the inputs of users and forwards to use in complex GIS processes. Within the Confirmation Module, there is a structured mechanism to analysis the user behaviour. Further this algorithm evaluates the users? credibility & reliability and then index him/her accordingly (c&r index). Then each data captured from the users are evaluated based on c&r index which the algorithm resulted. The scenario considered in the present work is flash flood forecast based on the visually estimated rainfall. However, as the rainfall can be observed by naked eye, its relatively easy to ensure the accuracy. Presently this scenario is under development to verify the model.
