GIS Software for Civil Engineering Verticals: An Overview
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.
Acknowledgements:
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.
