Our Work

CAD Case Study

Groundline supported a survey-based client specializing in LiDAR aerial surveys by delivering high-quality PLS-CADD modelling and transmission network assessments under tight timeframes.

Faced with large volumes of complex survey data, the client required expert support to efficiently process and transform this information into accurate, detailed network models. Leveraging strong technical capability and clear communication, Groundline streamlined data processing, improved modelling accuracy, and provided reliable outputs that met the client’s standards ultimately strengthening the partnership and enabling future project opportunities.
