Concepts of geographic information systems (GIS) have been around for more than 100 years, when our forefathers first started making maps to chart epidemics, for example. GIS began to take off in the early 1980s, when software-makers integrated mapping into computer-aided design.
Today’s GIS tools allow users to create searches, analyze spatial information and edit data to reveal spatial relationships, patterns and trends in an easily understood manner. The adoption of these technologies is having a positive impact on the surveying and mapping professions. According to POB’s study of GIS trends in surveying, firms are turning to GIS tools and software to serve clients.
