Following is a summary of an article published in Directions Magazine written by Nearmap geospatial technical engineer, Chuck Dostal:
Like the cartographers of centuries ago, today’s GIS professionals need to analyze and make critical decisions based on real facts on the ground.
Back more than 500 years ago, without the benefits of aerial perspective, mapmakers like Henricus Martellus created proximate renditions of the rounding of the Cape of Good Hope in South Africa. That suddenly opened the New World to Europe, via western routes of exploration that were once thought impossible. (Columbus may have used Martellus’ World Map to persuade Ferdinand and Isabel to back his voyages to the Indies.)

How much more powerful the tools are today, thanks to high-resolution aerial imagery and GIS, which can create exact renderings where each pixel on the map represents 2.8 inches on the earth. This kind of accuracy and easy access enables millions of pivotal decisions by businesses and governments to help develop new communities and enhance the quality of life.
