most of the algorithms. However, none of them seem to be available for use
except for the two "classical" ones -- {\DP} and {\VW}.
\cite{wang1998line} is available in a commercial product, which seems the only
algorithm specifically created for cartographic generalization and available
for general use. This poses a significant problem for map creation: without a
good simplification algorithm, every down-scaled map, of which creator did not
acquire a license for the said product will be of sub-par quality. The more
barriers there are for creating maps in open-source software, the less
open-source will fit the needs of the public, leading to even smaller
open-source applicability and community. We believe that availability of
high-quality open-source tools benefits the society as a whole, as opposed to a
single company producing the said tools, therefore we think it's worth
investing the effort into creating open algorithm implementations.
\cite{wang1998line} is an algorithm specifically created for cartographic
generalization and available for general use, though it is only currently
available in a commercial product. This poses a problem for map creation in
open source software: there is not a similar high-quality simplification
algorithm to create down-scaled maps, so any cartographic work, which uses line
generalization as part of its processing, will be of sub-par quality.
We believe that availability of high-quality open-source tools is an important
foundation for future cartographic experimentation and development, thus it
it benefits the cartographic society as a whole.
This paper will be reviewing and comparing two widely available algorithms that
are often used for line generalization:
