Data connectivity processing for road networks

There are a large number of fine lines in the vector route data, which may encounter problems when constructing the connected graph, so the following processing is carried out to ensure the connectivity of the network.

(1) Vector to raster: Convert road network data (or track lines) to raster data (arctoolbox conversion tool, turn to raster, polyline to raster, select the appropriate cell size this time using 0.001)

(2) Refinement of the raster converted from the trajectory line (Spatial analyst-> raster synthesis, refinement as the road network data so corner shape select sharp)

(3) Turn the thinned raster back to vector data (transform tool, raster to grid, and raster jog line)
