Figure 20: Sample (a) region, (b) its binary array, (c) its maximal blocks, and (d) the corresponding quadtree (after SAMET 1990a). IX he first textbook on GIS was published in 1986. Today, we can find dozens of books dealing with GIS. Yet, it is dif...

Web-based Geographic Information Systems and their Usability

Usability of web-based geographic information systems (GIS) applications is very important because these applications are mostly focused on end users, i.e. on people who may have only a very limited knowledge of GIS, if any. Many various usability evaluation methods have been developed. Some of them involve real users or their representatives, some of them are based only on GIS experts evaluati...
