CALPUFF land use module calculation and business system integrates TERREL (terrain pre-processor), CTGPROC (land use pre-processor), and MAKEGEO, to establish an order creation, order management and user management system. CALAPUFF is developed in B/S architecture, ASP.NET framework, C# object-oriented programming language and Microsoft SQL Server database platform.
Before using data service provided by CALPUFF land use module calculation and business system, the user needs to make a registration application to the system team, and submit specified materials and accept all terms of the user agreement. The system administrator will review the registration application and assign the user permission if the application is approved.
After login, the user should first fill in the order information, in which order number, order type, customer name and submission date are filled in automatically, contact, telephone, data year, UTM zone, X-coordinate, Y-coordinate, unit spacing, X-direction unit number and Y-direction unit number are required, and invoicing information, address, zip code and other information are optional. After submitting the information, the system will automatically check whether the order information is complete, and return it to the user for further supplement if incomplete. After the order is completed and submitted, an “unapproved order” will be created.
The administrator can review the order submitted by the user in “pending orders”. During the review, the order status will be changed to “being reviewed”, and the user can make search accordingly. If the order is disapproved, the user can make search in “failed orders” and view comments from the administrator. The order can be re-submitted after modification. The user can search the approved order in “orders to be paid”, and give payment according to the specified payment terms. After the payment is confirmed, the administrator will change the status of order from “unpaid” to “paid”, and confirm the invoicing information for order “to be invoiced” according to user’s requirement. Meanwhile the administrator should make calculation and confirmation for order “to be calculated”, so that the system can create calculation result as required by the order. The user can download the calculation from the “Completed Order”.
