Details

Native Apple GIS product delivered across macOS, iPadOS, and iOS for drone-supported site survey and planning review in Zurich

Used ArcGIS Maps SDK for Swift as the single mapping platform for 3D scenes, scene layers, offline areas, terrain, parcel context, and operational overlays

Connected drone mission planning, live grid scans, RTK/PPK telemetry, photo capture, LiDAR readiness, waypoints, battery status, and scan coverage in one shared workflow

Integrated AutoCAD-derived building envelopes, architectural drawings, sections, elevations, floor plates, and zoning geometry through Autodesk Platform Services and preprocessing pipelines

Supported compliance checks for maximum height, setbacks, facade area, view corridors, sunlight hours, shadow impact, clearance, site boundary, and zoning constraints

Presented desktop workflows for detailed planning review, iPad workflows for mission monitoring and site meetings, and iPhone workflows for field operations and property insights

Stored captured assets, orthomosaic outputs, 3D model versions, mission timelines, annotations, site metadata, and planning reports in cloud-backed project records

Used AI-assisted interpretation to summarize drone scan quality, explain planning warnings, detect model conflicts, compare survey states, and generate concise stakeholder notes
