3D Mapping and Modeling

3-D Mapping

3D modeling and mapping involves converting LiDAR data or 2D shapefiles that have known vertical elevations associated with the 2D coordinates to three dimensional digital terrain and digital elevation models (DTM and DEM) along with terrain irregular networks (TIN). This modeling and the analyses that can be performed with them are used for a wide range of applications which AJD Geospatial Concepts can undertake including:

  • Topographical analysis and site planning for land acquisition and development.
  • Flood inundation mapping and analysis for emergency management, land development, and insurance planning.
  • Park, recreation, facility, and trail site locations.
  • Corridor mapping for power lines, pipelines, roadways, and railways.
  • Building footprint, height, and line-of-sight modeling analysis.
  • Mapping and modeling historical development of cities and towns by combining 3D data with historical data for an area.
LiDAR and three-dimensional data are available through State and Federal databases.

My Experience

Using ArcGIS and LP360 software, I have completed a number of projects involving three-dimensional modeling and mapping with both LiDAR data as well as 2D shapefiles containing elevation data. These include:

  • Creating a TIN terrain model and contour map of Marion County along with 3D floodplain map of Prospect, Ohio on the Scioto River for emergency management planning.
  • Creating a Digital Terrain Model of impervious surfaces to show storm water collection points and drainage in the City of Marion, OH.
  • Creating 3D map of structures to show the historical development in downtown Charlottesville, VA. (Pictured Below)
