In this case study, BHSoft helps customers to build a SNS system to predict and tackle natural disasters.
The client is a Japanese firm who provides manufacturing solutions to manufacturing industry. In particular, they develop various automatic design systems based on CAD, developing structural analysis and integration system for construction/ civil engineering fields, providing environmental evaluation simulation as well as GIS asset management solution.
This client has been loyal customer of BHSoft for a certain period of time and they plan to continue to co-operate with BHSoft.
BHSoft has years of experiences working with Geographical Information System (GIS). This time we build a geospatial data information system for the purpose of monitoring and evaluating information on natural disaster. This information will be showed on the dashboard screen.
The SNS system monitors predefined keywords and then list all essential statistics on the dashboard. The keywords are the name of natural disasters along with all related information.
