Digital ROW Utilities

Plan Sheet Library - digitize PDF plan sets (the biggest addition) - Import PDF plan sheets and overlay them on the map (free-positioning, GeoPDF metadata + sidecar world-file auto-positioning, correct page rotation) - Auto-extract utility symbols and lines from plan sheets using on-device Vision (contour + OCR + PCA detection) - Process entire plan sets: orchestrator classifies every page, parses G-series sheets into a survey alignment, reads tabulation sheets, projects station+offset to WGS84 lat/lon - Tap-to-place waypoints (two-tap lines, DTCD-style), export placed waypoints into your project, per-feature and bulk delete - Endpoint snapping and dedup so multi-sheet lines bond into continuous runs - View the original PDF alongside a minimizable control panel Aerial imagery & georeferencing - Import georeferenced aerial imagery (GeoTIFF) with an on-device bounds inspector - State Plane reprojection (Iowa, Minnesota, Wisconsin, Illinois, Missouri), Helmert 2-point fit, multi-tiepoint GCP, US-survey-foot and NAD27 support - Aerial + plan-sheet overlays render on the map, as ground-projected planes in AR, and bundle into KMZ (GroundOverlays) and PDF report exports AI detection - On-device aerial utility detector with an active-learning feedback loop - AI detection confirmation sheet; material cert scanner (MAPLE/OCR auto-fill) WFS catalog overhaul - Sources ranked by true distance; new Nationwide section, 50-mile radius, and service/portal filters - Map now renders on MapKit (MKMapView) - fixes freezes and out-of-memory crashes on dense sources - Removed attribute-only services (no geometry); clear messaging when a source has none - Add a source (saved locally first), report a broken source, plus automated weekly catalog maintenance External RTK GNSS - Vendor-neutral support for external receivers (Emlid, Eos, Bad Elf, Geode, Trimble) over NTRIP, with location-start fixes Permit & DTCD integration - Create a Digital Traffic Control Diary closure from an active permit (carries work areas), with a deep-link banner to the new closure - Active-permit map focus and polygon filtering; permit defaults auto-populate new permits Export & certification - Added GPX, GML, and XLSX export formats - PencilKit signature capture for ASCE 75-22 certification UX/UI overhaul (the May audit — 5 batches) - Long-press placement, editable feature inspector, provenance glyphs, undo/redo with persistent stack, domain filters, tap-to-inspect on all maps - Data-loss confirmations, clearer save buttons, 44pt tap targets, modal-stacking guards, skeleton loaders Stability - Fixed PDF text-extraction crashes (CGPDFScanner fallback for broken fonts), OOM crashes on dense map data, and several map-camera focus bugs
