About this courseSkip About this course
Maps are graphic representations of reality and help us understand and navigate the world around us. Maps can incorporate third dimension through contours, hillshading (3D modeling), and profile views.
In this course you will learn fundamentals of third dimension (3D) GIS concepts and tools to visualize, analyze, and interpret geospatial data in 3D, enabling you to reveal patterns and relationships for more effective problem-solving and decision making.
When the data include the third dimension, ArcGIS Scene allows us to navigate through the data in 3D space. This makes the data and the problem more understandable and reveals new visual insights. Visualizing and processing the data in 3D allows us to include real-world elements in the analysis such as undulation of terrain and 3D extent of trees, building, and subsurface geology.
Our world is three dimensional and many GIS applications now require 3D analysis. Esri’s ArcGIS Scene allows us to visualize data on a world sphere. It provides a variety of tools for orientation, navigation, search, data preparation, building workflows and spatial analysis.
3D mapping and visualization is used in a variety of industries and academic disciplines:
- Monitoring forest stand height and age
- Volumetric analysis of resource extraction from a mine or water level in a reservoir
- Watershed delineation to assess inundation risk, land management, environmental monitoring
