Effective management and sharing of geodata is one of the priorities of governments and companies all around the world. Nowadays spatial data are published without any standardized methodics and unified metadata. This situation leads to multiple storing of such geodata and consequential high expenses and inconsistency. There is usually a problem even find an appropriate mapserver with the required data. Obviously there is a problem: How to access geodata more effectively. We are searching in emails, discussions, documents around the web, even in pictures. But currently there is no searching engine for geodata which could be compared with well known searching services such as Google, Yahoo!, etc. Therefore I focused on this issue. The first part of this work briefly presents standards used for publishing geodata. A review of methods used for geodata and metadata aggregation follows. Based on this review, a method for development of an engine for geodata search is presented. Last part describes principles of experimental implementation and achieved results.
