A Visual Aid for Cartographic Road Adjustment

Abstract

The objective of this project, carried out at CPAC Systems, was to develop an ap plication that supplies a visual aid on which manual assessment for cartographic road additions and adjustments can be based. It is meant to be used at worksites where the landscape often changes. When the landscape changes, so do its roads, and the cartographic information in the system needs to be updated. A model was created based on data extracted from CPAC’s database, containing cartographic information about a worksite and a half hour’s worth of vehicular movement by five vehicles. An application that achieves the objective was developed by using Matplotlib to plot a combination of a decaying density heat map and line segments filtered via orthogonal vector projection and ray casting. Additionally, the appli cation provides the user with reasonable suggestions for road additions. A feature that provides suggestions for road adjustments was not implemented due to time constraints; this could be the starting point for future work.
