Topographic Map of Engineering Calculation Program Design

Abstract Nearly years, Chinese society develops continuously. Government is putting much efforts to develop infrastructure, various size of the project in different field are increasing. Digital topographic map has many advantages comparing with the traditional analysis diagram maps , so It can be widely used in various construction projects.

Using existing digital topographic map to solve common compute problems (road curve calculation, size and perimeter of area, road - section drawing, the depth of cut and fill and earthwork calculation and two dimensional coordinate transformation) in the construction project and calculating it programmatically are very necessary.

This article is about topographic map of VB engineering calculation program design,which can Automation solute above calculation issues automaticly. It will play an important role in speeding up the progress of construction、making the design

optimization better、improving the accuracy of engineering calculations.

Key Words: VB programming design vertical and transverse section earthwork calculation road curve circumference and the area two dimensional coordinate transformation
