Design of Webgis for Computer-Aided Design Data Transformation and Road Topography Visualization Based on Digital Elevation Model
Road engineering drawings are commonly archived as two-dimensional CAD files whose layers, entities, curves, and local topology do not directly form analysis-ready geospatial objects. This paper presents and evaluates a WebGIS artifact that transforms CAD road drawings into traceable 2D GeoJSON, reconstructs roads, bui...
