In 2005, Japan Geotechnical Consultants Association (JGCA), Japan Society of GeoInformatics (JSGI) and Geological information Utilization and Promotion Initiative (GUPI) developed Web-GIS system for management and publication of geotechnical survey reports, which are created according to the standard form decided by the Ministry of Land, Infrastructure and Transport in Japan. The Web-GIS system is called "Web-titan" and the functional enhancement and improvement of Web-titan have been continued under Web-GIS consortium organized by 23 companies in conference members of JGCA now.
Web-titan is designed in Server/Client environment. The server consists of free software and open source software downloaded from Web such as Fedora Core OS (http://fedoraproject.org/), Apache (http://www.apache.org/), MapServer (http://mapserver.gis.umn.edu/) and MapLab (http://www.maptools.org/maplab/). Apache is an open source web server which runs on multiple platforms. MapServer is a Web-GIS mapping engine with an open source development environment and MapLab is a suite of effective web-based tools to create and manage MapServer web mapping applications. Clients are ordinary PC connected with Web-titan server via internet or intranet and we can operate Web-titan by using web browser such as Internet Explorer and Firefox.
The main functions of Web-titan are shown as follows:
1) We can easily register geotechnical survey reports by using the registration tool and manage them by DataBase.
2) We can search geotechnical survey report by keywords such as name, address and date and browse a report and its related photographs, drawings, borehole logs and so on.
3) We can look for position of boreholes on digital maps and browse its borehole log and core photographs.
4) We can construct and publish web mapping applications by using functions of Web-GIS. Because this server has functions of WMS (Web Map Service) server/client and WFS (Web Feature Service) server/client, we can use WMS and WFS layers in the web mapping applications. GUPI developed and has published web mapping applications for disaster map of 1964 Niigata earthquake in Japan (http://www.web-gis.jp/titan/htdocs/niigata-jishin/niigata-jishin.phtml) and field excursion guide to Miyake Island in Japan (http://www.web-gis.jp/miyake/htdocs/miyake.phtml).
Free version of Web-titan can be downloaded from Web site http://www.gupi.jp/web-gis/.
In this presentation, we will introduce the functions and use example of Web-titan.
