GIServer is a Web Map Server (WMS) for Windows that uses the freeware inovaGIS automation objects
server in combination with the Microsoft HTTP Server (Microsoft Internet Information Server 4.0
if you use Windows NT) or Apache Server for Windows, to access geographic information.
The data can be located in various servers or locally, and the user can choose from a list of online servers where the data should be processed.
GIServer preview release 0.9 includes several new developments. The most important ones are
the use of specific parameters (check out GIServer Parameters) and their integration with Styles (check out Making use of Styles),
Data Dimensions (check out Adding dimensions), automatic legend creation and legend service (check out legend parameters), dynamic query methods for vectorial data (check out vectorial query parameters)
and the automatic geographic projection of requests (check out the EPSG available). All this is
enhanced with the use of a geographic cache system.
Service Chaining is also included in this version and gives the possibility of creating new
services or data functions with CGI, ASP or PERL web pages. For more information about this
check out Creating a New Function* (registered version).
NOTE :
The GIServer was fully tested in the following Windows Systems and service packs:
- Windows NT 4.0 - IIS 4.0 - Service Pack 6
- Windows 2000 - IIS 5.0 - Service Pack 2
- Windows XP Professional - IIS 5.1
- add your own ...
The GIServer does NOT works in the Personal Web Server (Windows95/98) because this light weight HTTP server do not support multiple concurrent requests. All the test realized failed but if anyone knows a way to change the settings of concurrent requests in this HTTP server please let me know.
To help you develop your own GIServer web pages here are some examples and source code:
- Changing the GETMap request (go)
- Using Mouse Events (go)
- Cascading requests example
- Requesting Web Map Server Layers (go)
- Requesting Web Map Server Temporal Layers (go)
