Ilola – Vierumäki, Vantaa FI and Minor EFHK Area Fix

This add-on improves the Vantaa area near Helsinki, Finland, with enhanced terrain, photogrammetry, and scenery based on Google Maps data. It specifically addresses issues such as terrain anomalies, misaligned roads, and missing or inaccurate buildings, especially near Helsinki-Vantaa Airport. Neighborhoods covered include Vierumäki, Kulomäki, Maantiekylä, Ilola, and parts of Aviapolis. Some visual or color inconsistencies remain, and the add-on may place higher demands on hardware.
