Development of an ArcGIS Pro add-in for updating BDROUTE-NC, New Caledonia's authoritative road network database: worksite integration, 3D punctual editing and road-name management.
Context
DITTT maintains BDROUTE-NC, the authoritative road network database for New Caledonia, stored in a versioned SDE enterprise geodatabase on PostgreSQL at DINUM. To keep it current, the Bureau de la Cartographie regularly integrates cartographic restitution worksites delivered by external contractors, applies punctual geometry and attribute corrections, and synchronises road names provided by partner departments. The V1 toolset had reached its limits. MAGIS developed V2 as a single ArcGIS Pro add-in, consolidating all tools under a dedicated ribbon tab.
Solution
Worksite integration — When a contractor delivers a new survey over a given area, the new segments must replace the existing data while inheriting its business attributes (surface, direction, speed, classification…). The add-in automates this matching with a matching rate above 95%. A dockable validation panel handles the remaining cases visually before committing to the versioned geodatabase.
Punctual update — 8 guided tools (Create, Import, Merge, Split, Delete, Extend, Replace, Attributes) allow direct network corrections. The operator only draws alignments; the add-in automatically manages Segment-Node topology and Z-value interpolation from the DEM.
Name management — Road names are supplied by partner departments. A dedicated panel in the Attributes tool allows assigning, removing or searching a name (by code, label or manager) without leaving the editing workflow.
Outcomes
Automatic matching rate of 99.72% on a 1:10,000 restitution worksite covering the Nouméa metropolitan area.
Deliverables include the compiled add-in, source code on GitLab (open to DITTT), a technical guide and a user guide.
