Abstract

Maintaining High Accuracy in Today's Geodata
Track: Technology
Authors: Sam Knight

Survey grade geospatial data is a key component in everything from planning and decision-making to plan execution, and ongoing maintenance of a project. Geodata can be extremely valuable when gathered, managed, and used correctly. However, data corruption is all too easily introduced into the geodata lifecycle. Without proper checks and balances through a combination of education, training, software, and clearly defined processes, accuracy degradation can go unnoticed until it is too late, and potential mistakes have already become reality. This talk will cover key concepts of maintaining high accuracy data, such as storing time-based coordinate data and other cutting data types, identifying and preventing processes that degrade data quality, and the real need for good metadata.
