GPS: Data Collection, Processing & Application

Presentation Abstract

GPS data and its application to mapping, surveying and site control can be a confusing topic. This presentation will focus on identifying the various accuracies of GPS equipment. Application examples will be investigated as to determining user needs. Whether you are mapping manhole covers or park boundaries, accuracy is an issue How to achieve accuracy. How much do you need? How to determine confidence in your data. Appropriate use of various GPS data. Technically orientated description of the differences in accuracy of the various GPS signals and supplementary “real time” correction services available. Discussion of GPS data collection applications. Emphasis on determining how much accuracy is required for various tasks and choosing the proper equipment for the identified tasks. Opportunity for “hands on” comparisons of several grades of GPS equipment. This workshop is designed for the field data collector as well as the analyst that uses the data.
