All countries have their own geographic coordinate systems, as most users of GIS applications will be aware. And while global geographic coordinate systems have been around for some time, they tend to be underused. One of the major disadvantages of a system like WGS84, for example, is that it is based on degrees, making it particularly hard to estimate lengths and distances. The Mercator cylindrical map projection, for its part, visualises the world as a rectangle, which causes the poles to be extended and the equator to shrink, thereby creating a distorted image. That being said, local coordinate systems also come with their share of drawbacks, one being that they make registration outside the country or territory either difficult or impossible.
Speer IT has spent the past few months developing a solution to this problem by introducing separate ‘Save’ and ‘Display’ options, as an alternative to having to make a selection between the two. Users can choose which coordinates they would like to see displayed on their screen, while the data is saved to a generic coordinate system, equipped to facilitate and manage highly accurate worldwide registration. In addition, the country selection for imported files and addresses is no longer integrated into the environment, and users can modify this themselves independently of the active country and coordinate system selected.
All environments will be migrated to the new system over the next while. These updates ensure that environments are no longer tied to individual countries and that registered networks can expand virtually without limitation. It also guarantees that Cocon will remain ahead of the curve by anticipating the needs of its growing population of users and clients.
