Geographic Information Systems have become a prevalent method of analysis in civil engineering. Flexible GIS models that manipulate compile and process spatial data above or below the earth’s surface have provided a powerful tool in civil engineering applications. To realize this RMSI provides a wide range of Geographic Information Systems services and solutions such as geological applications, Bore hole study, ground engineering, geotechnical engineering, environmental engineering, rural, urban and regional planning. For projects where spatial representation and analysis are not separable from the science and substance, RMSI provide the experience, intellect and self-guidance needed to produce top-quality GIS applications.
RMSI works at all project levels, from project management, to production, to technical services. Depending on a client’s needs, we perform routine task, or take charge of an entire project, from team building to creation of maps and models. RMSI GIS technical services cover the full range, from map production, to spatial analysis, to remote sensing, to application development, to on-site GIS project executions.
For MapAsia 2002, we would like to present few top class software applications developed for our Japanese Client – Oyo Corporation to demonstrate RMSI GIS engineering capabilities to meet complexity of the problem maintaining world-class quality. Applications to be presented at MapAsia 2002 will be:
- OYOGIS Software: A geotechnical GIS application.
- NETGIS: A fast and scalable enterprise solution for Intranet, and Internet using web technologies.
- BH Manager: Aim is to create a user-friendly environment for loading Borehole data, associating Borehole Images with the selected borehole in ArcView and then Printed on the Plotter.
To address the title of the paper the authors preferred to present the content comprising three applications in brief in the form of case studies as follows.
Case I – About OYOGIS
OYOGIS is an integrated multi-lingual desktop GIS application designed to perform geological data analysis and extract geological information from spatial and non-spatial data. OYOGIS is intended for geo-technical professionals and consultants involved in water resource management and infrastructure related projects.
Geo-technical engineers using this application can relate alignments and cross-sections find the geological composition of a specific point along the alignment, associate documents related to a specific location on the map, and create thematic maps based on attributes of a map. Engineers can also zoom to specific parts of an alignment and see the associated cross-section area, perform spatial and non-spatial queries, and print required reports and maps.
There are administrative and client components to the system. This gives managers the control needed when dealing with large projects and data sets. The administrator can create, delete, and update users and user rights, create projects, and also audit any data changes made by users.
The system is open enough to support different types of data and can be customized to fit specific user needs. The software configuration used for OYOGS includes Visual Basic 6.0, Crystal reports for report creation and generation, VC++ for custom DLL’s, and ESRI MapObjects for the display and analysis of maps.
Case II – About NETGIS
NetGIS is a bilingual web based application developed by RMSI for the corporate intranet of the OYO Corporation Japan. It gives its users the power to visualize geographic information, search and navigate through spatial and aspatial data, perform analysis on data and print reports for future use. The application is intended to help in feasibility studies for construction activities, aid in construction planning and assist in facility management.
The application is designed to perform geological data analysis and extract geological information from spatial and non spatial data. NetGIS has a perfect blend of all common desktop GIS application features like zoom-in, zoom-out, pan , feature identify, search, print and thematic maps. Geo-technical engineers using this application can relate alignments, find the geological composition of a specific point along the alignment, associate digital documents related to a specific location on the map, and create thematic maps based on attributes of a map. Engineers can also perform spatial and non-spatial queries and print maps at scale.
There is an administrative component to the system. This gives managers the control needed when dealing with large projects and data sets. The administrator can create, delete, and update users and user rights, create projects, and also audit any data changes made by users.
- The application is currently meant for intranet deployment and uses MapXtreme-Java in its middle tier for map-data processing
- At the back-end is Oracle database (that can be easily replaced with any other RDBMS like MS-SQL server)
- The map rendering and image creation is done at server using MapXtreme servlets and then the response is sent to browser.
- The system has been tested extensively for load tests using Rational suite of tools and is found to give stable performance while delivering high scalability
- It can support up to 100 concurrent users with simultaneous requests being received at the server from clients – the testing platform being: MapXtreme Server: PIV 2GHz Dual Processor 1 GB RAM; Database Server: PIII 450 MHz 512 MB RAM
Case III – About Bore Hole Manager
The Borehole Manager Project is specifically customized for the Punjab State Tube well Corporation. This Project allows the users to Load the borehole data (captured through GPS / Digitizer), and also Link & View / Print the Borehole images. Aim is to create a user-friendly environment for loading Borehole data, associating Borehole Images with the selected borehole, which can then be viewed in ArcView and then Printed on the Plotter.
Some of the major processes/functions are as follows:
- Data Transfer from GPS device to GPS Pathfinder and then Export GPS data to ArcView Shape Files through GPS Pathfinder
- Exporting the Borehole Log to Borehole BMP Images through Viewlog Load Borehole location data using ArcView Merge Borehole Shape files / Themes Link/Associate Borehole Image (Images Exported through Viewlog) using ArcView
- View/Print/Plot Borehole Image using ArcView Printer/Plotter
The above mentioned three cases has been defied in separate sheet below to realize the scope, need and technology used to address daily civil engineering GIS needs in practice.
Authors takes this opportunity to thank RMSI team and Oyo Corporation, Japan in particular for sponsoring the project, which has been derived from the actual need from their business perspective. From Oyo, authors would also like to thank Mr. Yamada Toshihiro and his team for providing technical support throughout the project for its successful accomplishments.
