Сбор и подготовка баз данных навигационно-гидрографической информации для создания ЭНК Ладожского озера

Marine Geodesy involved in long-term project "Ladoga lake ENC production with all water area hydrographic survey operation". The main project activities include:

• Initial navigational and hydrographic data gathering
• Hydrological measurements
• Navigational objects positioning
• High resolution MBES survey (critical areas, channels and routes, plan scale 1:5000) of the 695 km² water area
• Comprehensive SBES survey (plan scales 1:50000 and 1:100000) of the 2088 km² water area
• Survey data base preparation for ENC production
• Charting and reporting

Modern hydrographic equipment was used in project (dual head multibeam systems Reson IDH T20, high resolution MBES Reson T50 and high precision SBES Navisound  NS15).
Survey vessels positioning was executed in RTK-mode with centimeter level accuracy. Ladoga lake surveys were performed within the tight schedule according to IHO standards.
