Service Oriented Geospatial Data Management using Free and Open Source Software-A Prototype for Northern Region of the Philippines

要旨

The RGIN project is one of the SDI initiatives at a regional scale in the Philippines. The RGIN project is supported by several foreign countries through ODA funds. During the initial period of the RGIN project, proprietary software was adopted for system development. The project initially made little progress and was suspended over a few years due to budget limitations and lack of knowledge on proprietary software solutions. However, FOSS accelerated the project progress. The Web-GIS prototype for SDI was developed using Open Source solutions and the technology was transferred to local staff to manage the system. As a part of this research, Open Standards compliant prototype system was developed to archive interoperable transactions in a distributed environment. The RGIN system now provides an effective SDI framework to promote geo-spatial data sharing and management. The system also offers an efficient solution for data discovery through scalable and interoperable systems based on OGC standards. The geo-spatial data transactions in the prototype system are examined using various kinds of GIS clients such as desktop GIS, web mapping client, mobile GIS and virtual globe viewer, while OGC CAT standard is implemented for metadata search. The project is now in phase of being encompassed all over the Philippines. The prototype system can be applied for other regions, expanding to a national level SDI.The RGIN project is one of the SDI initiatives at a regional scale in the Philippines.
