Data Processing services from MDL Technical Services Division

Advancements in laser measurement technology now mean it is possible to collect huge amounts of survey data quickly and efficiently, however this is often at the cost of increased office based data processing times. MDL recognise this and have therefore launched the data processing service to assist customers in processing, editing, and managing LiDAR data without the large capital investment needed in specialised resource, software, and training. MDL has brought together a team of industry professionals to offer a comprehensive turnkey service with an emphasis on quality and reliability.


MDL offer a wide range of services and deliverables in industry standard CAD/GIS formats
