Civil Engineering design surveying calculation software - surveying calculations for curve geometry, topographic surveying, and unit conversions. Covers calculations for horizontal curves, vertical curves, spiral curves, lattitudes and departures, azimuths, northings and eastings, area measurement, topo leveling, earthwork volume and distance measurement. Supports 32 bit,( x86) and 64 bit (x64) architecture for Windows Operating Systems. Program has built in reference manuals, and coefficient tables for a stand-alone design application. Can open multiple windows to perform multiple calculations at one time and solve complex civil engineering design problems.
