AstroWeb – A Graphical Representation of an Astronomical WFPDB Database Using a Web-Based Open Source Geographical Information System
Keywords:Geographic Information System, GIS, Web-Based GIS, Graphical Data Web-Access
The purpose of this study is to present the open-source Map-Server and the way it can be used as a Web-based Geographic Information System. The MapServer object model is analyzed and algorithms are proposed for geo-referenced spatial data dynamic representation. The results of this analysis are used in the development of our application called AstroWeb. AstroWeb presents graphically the application data of the Plate Archives catalog (CWFPA v.2011) of Bulgarian Wide-Field Plate Database and ensures fast and easy access to the digitalized plate information.
