Allison developed an automated approach for converting the City of Tukwila’s point-based GPS inventory of stormwater infrastructure into an inter-connected linear network of pipes with associated tabular information. She created scripts in AML, Perl, and Python that use the surveyed azimuth of each catch basin’s incoming and outgoing pipes to find the most likely catch basin or drain point to connect to. When these data were thoroughly reviewed, the automated approach was correct approximately 80% of the time. This technique saved many hours of tedious, manual digitizing to connect these points.
