ABSTRACT: By emerging the OGC web
services technologies which caused server interoperability in geospatial
fields, a rush toward implementing geoweb services commenced among most
governmental enterprises. The massive geospatial information which has been
produced in various offices during previous years, and which was not available
for public customers because of protocol difficulties, now had a chance to be restructured
as OGC specifications and be reachable to huge amount of keen clients via
Internet platform. Increasing number of map presenters in web environment
raised a search facility requirement in spatial data area. These kinds of
search abilities are called “Geoportal”, which provides client applications
that use several geo services such as catalogs and web map services. How to
implement a suitable geoportal to meet the needs, has brought a set of hard
challenges for governmental geospatial owners. In this study we present an
overall concept of service oriented architecture and its consequence web
service specifications and eventually web catalog services which are
fundamentals of developing a geoportal. It also declares some experiments on
importing/exporting data between geoportals, which is known as harvesting
method.
