 \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 to implement an algorithm
+for an avid GIS developer. Once the algorithm is implemented and integrated to
+open-source GIS solutions (e.g. QGIS), rivers on future large-scale maps will
+look professionally downscaled.
