Digital Elevation Model (DEM) refers to a solid ground model that uses a set of ordered numerical arrays to represent the ground elevation through the digital simulation of limited terrain elevation data. Digital elevation models (DEMs) are an indispensable part of geographic information systems (GIS) and can be used in various fields such as terrain analysis, hydrological analysis, planning, and environmental monitoring.

Overview of Market Development

In recent years, thanks to the acceleration of urbanization, the popularization of LIDAR technology, and strong government support for GIS infrastructure development, the global DEM market has steadily grown. According to our research data, the global DEM market size is estimated to be $990 million in 2024, an increase of 12.91% from 2023, and is expected to continue to increase to $1812 million by 2029.

Analysis of Market Competition Pattern
