aerial perspective: Photogrammetry Helps GISers Overcome Challenges of Island Life

摘要

It's easy for people to take for granted the convenience of location information. Our minds are chock full of it. We drive to work, school, or run errands every day with knowledge of where we are going and an internal clock that tells us how much time it takes to get to a particular destination. If we are unfamiliar with our destination, internet mapping tools using geographically-based data provide a very useful convenience to determine route, distance, and travel time. In addition, government organizations such as emergency response and law enforcement rely heavily on precise location data to serve the general public. When information like this becomes such an integral part of our everyday lives, it is easy to overlook the amount of work required to provide accurate and reliable geographically based, or geospatial, information.
