Introduction The Delphi/Kylix GIS components connect your application with a WMS or UMN map server. The map viewer component has all the basic functionality for viewing, navigating and querying maps. WMS (Web Map Service) is a specification of the Open GIS Consortium supported by many free and commercial web mapping servers. You can use maps from the numerous public WMS or UMN sites with native GUI elements - without browser. These components are written as portable CLX components and tested with Kylix 3 and Delphi 7.

Introduction Ruby is the interpreted scripting language for quick and easy object-oriented programming. It has many features to process text files and to do system management tasks (as in Perl). It is simple, straight-forward, extensible, and portable. This component embeds the Ruby interpreter in a Kylix/Delphi application.
