In MacEachren and Kraak’s article titled Research challenged in Geovisualization, they argue that the main issues in geovisualization lies in representation, integra- tion with knowledge construction and geocomputation, interface
design, and cognitive-usability issues. The role of geovisualization has changed drastically within the last 10 years, along with developments in other software’s and technologies such as web 2.0.
Represent this dynamic data is a far cry from paper maps, where the database and map were static, and connected. One of the other challenges that has surfaced in representation is that of the geovisualization of 3-d and 4-d (time) space. This challenge in representation is still being addressed as the technology grows more powerful. Great strides have been made with interfaces, where 10 years ago many things were only useable by experts, now everyone and their grandma are using them.
Many of these problems have not yet been solved, however some of them have. Storing of the data is no longer as much of a problem due to cloud storage, and the web2.0 has become much more user-friendly, making it useable by users with limited expertise.
