When it comes to the business of drone surveying, understanding elevation models is paramount. Three of the most used models are the Digital Terrain Model (DTM), the Digital Elevation Model (DEM), and the Digital Surface Model (DSM). These models serve as crucial tools in understanding terrain details. They are instrumental in various fields from land development, construction volumetrics, and surveying. In this article, we examine the fundamentals of elevation models, their significance in drone surveying, and applications for their use across different industries.

In the dynamic realities of coastal land management, the delicate balance between preserving natural beauty and fortifying the landscape against environmental threats is a constant challenge. In this article we will look at a case study in coastal renourishment: How Mount Construction leverages cutting-edge drone technology to document and enhance beach renourishment initiatives in Avalon, NJ. We will explore the powerful use of drone technology combined with environmental stewardship, and community resilience. All of which will showcase the pivotal role drones play in shaping coastal management.

In the ever-evolving landscape of geospatial technology, drones have emerged as invaluable tools for surveying and mapping the Earth’s surface. Among the various techniques employed in drone surveying, planimetrics stand out as a fundamental feature, enabling the capture, analysis, and interpretation of two-dimensional data essential for a multitude of applications.
