Survey Calculations Using A PDA

(Protable Digital Assistant)

By Zhu Hong Yue

Supervisor - Chris Rizos

 

Introduction

 Surveyors have being using electronic calculators to do survey calculations for a few decades by now and as technology changes so do the calculators they use. From where we stand now, it just seems logical that the next step in surveying calculators will involve large colour display, ever increasing computation power and storage space and the ability to integrate and communicate with the rest of the office.

Portable Digital Assistants (PDAs) already has many useful functions such as the organiser, mobile phone, GPS, internet and networking capabilities. This program will add the function of a survey calculator to this list and eventually eliminate the need of carrying a separate calculator for field calculations.

This project explores the possibilities of creating a program that performs survey calculations using VB.NET and also assessing itís viability as a commercial product in the NSW surveying industry.

There is heavy emphasis on the program being user friendly. The product is primarily aimed at surveyors but should be intelligible by anyone who can use a regular PC.

the resulting program is a survey calculator, called Computron, containing 2 parts. Firstly, a base calculator which performs a number of mathematical calculations and some survey calculations, all in Reverse Polish Notation. The second part of the program performs a close function for loop closes traverses and also between 2 known points.
