User Interface for Project Based Spatial Information Accession

A subset of spatial information that many people deal with is "geographical" information. It is related to location on the earth's surface. Our most common encounter with this type of information is through topographic and tourist maps, nautical charts etc. With the advent of remote sensing, the maps generation has taken a new turn in addition to topology. The remote sensing data is being used for updating existing maps. Remote sensing data has various applications in many fields from planning to implementation and management of projects. With the advances in Sensor technology, resolution of remote sensing data improved rapidly. With the availability of commercial image processing packages, most of the processing and analysis of remote sensing data is being done at the user end as per their requirements. In case of application projects like Urban planning, layout survey etc, the polygon of the Area of interest will be provided for optimal data procurement rather than using satellite reference for data procurement. There is no tool for Spatial Verification of the data received from the satellite operator against the order. A database along with simple GIS support utility can be maintained for the supplied data along with metadata. As the data supply will be in stages, the updation also will be in similar fashion. The GIS utility provides tools for metadata insertion into database, accession of database with varied combinational queries and visual evaluation of the data procured. The coverage can be evaluated against requirement. Data pertaining to many projects can be archived into the single database and can be retrieved with respect to project particular reference. The software is developed using Java as front end to make it platform independent and web based and MS-Access as backend to cater the small-scale user requirements. This paper discusses about various aspects of package design, development and the mathematics usage and software tools used. The suitability of the package for various application projects in detail.
