An evaluation of measures for quantifying map information
Författare
Summary, in English
measures of amount of information and distribution of information. The evaluation is performed by (1) defining measures, (2) implementing the measures, (3) computing the measures for some test maps, and finally (4)
comparing the values of the measures with human judgement of the map information. For amount of information, we found that the measures number of objects, number of points and object line length had better correspondence with human judgement than object area. We also found that measures based on the size of Voronoi regions (of objects respective points) can be used for identifying distribution of information. The
results are based on the testing of only building objects. Future work should extend the test, using all object types.
