Raleigh links drone surveys to municipal GIS to keep its digital twin current

Raleigh is bringing drone capture, imagery processing and GIS publishing into a common workflow for updating its digital twin. GeoAI-based pavement-marking identification remains experimental rather than a demonstrated citywide capability.

For municipal teams, feeding new surveys into shared GIS can make changing site conditions available beyond the project that commissioned the flight. The practical value depends on how consistently the city maintains coverage and freshness, neither of which is quantified in the supplied material.

Raleigh is connecting drone surveys to its municipal GIS so observations of construction, infrastructure and storm damage can update a shared digital representation of the city. The workflow uses Esri’s ArcGIS Flight for mission planning, Site Scan to process imagery into True Orthos and 3D meshes, and ArcGIS Online to publish the results. Drone surveys of the new city hall construction site provide a practical example of capture feeding the wider city model rather than remaining a standalone photographic record. The operational shift is toward maintaining the model through routine municipal work, rather than treating it as a one-time visualisation. Raleigh is also experimenting with GeoAI to identify pavement markings, with further feature extraction intended. The supplied material describes the workflow and an application, but does not establish update frequency, citywide coverage, AI accuracy or measured operational savings.
