\section{Abstract}
|
|
\label{sec:abstract}
|
|
|
|
Ready-to-use, open-source line generalization solutions emit poor cartographic
|
|
output. Therefore, if one is using open-source technology to create a
|
|
large-scale map, downscaled lines (e.g. rivers) will look poorly. This paper
|
|
explores line generalization algorithms and suggests one for an avid GIS
|
|
developer to implement. Once it is implemented and integrated to open-source
|
|
GIS solutions (e.g. QGIS), rivers on future large-scale maps will look
|
|
professionally downscaled.

\section{Introduction}
|
|
\label{sec:introduction}
|
|
|
|
Cartographic generalization is one of the key processes of creating large-scale
|
|
maps: how can one approximate object features, without losing its main
|
|
cartographic properties?
|
|
|
|
Generalization algorithms are well studied, tested and implemented, but they
|
|
expose deficiencies in large-scale reduction (\cite{monmonier1986toward},
|
|
\cite{mcmaster1993spatial}, \cite{jiang2003line}, \cite{dyken2009simultaneous},
|
|
\cite{mustafa2006dynamic}, \cite{nollenburg2008morphing}).
|
|
|
|
There are two main approaches to generalize lines in a map: geometric and
|
|
cartographic.
|
|
|
|
\cite{stanislawski2012automated} studied different types of metric assessments,
|
|
such as Hausdorff distance, segment length, vector shift, surface displacement,
|
|
and tortuosity for the generalization of linear geographic elements. Their
|
|
research can provide references to the appropriate settings of the line
|
|
generalization parameters for the maps at various scales.
