Generates Brazilian aerodrome and heliport protection plans (PBZPA/PBZPH), obstacle surfaces, OPEA checks, CAD/KML exports, and SYSAGA support sheets.
PBZPA/PBZPH Builder is a QGIS plugin for Brazilian aerodrome and heliport protection planning. It generates 3D obstacle limitation surfaces for PBZPA workflows from runway threshold coordinates, supports inactive runway ends, records the applicable SSPV sector, creates an OPEA layer for obstacle review, runs preliminary OPEA versus surface checks, and exports KML/KMZ, DXF, optional DWG through ODA File Converter, SYSAGA support information sheets and elevation tables. The heliport PBZPH mode is available as a project type selector, but PBZPH drawing and sheet generation are blocked until the authenticated SYSAGA Annex B field structure is confirmed. External optional dependencies: ezdxf for DXF export, onnxruntime for machine-learning OPEA suggestions, and ODA File Converter for DWG conversion. Documentation: see README.md and docs/user_manual.md in the source repository.
