Chestertown Comes to Life in 3D

With the help of students and staff, the Chestertown 3D project incorporated data from multiple locations to create a full 3D visualization of the Chestertown, Maryland Historic District (Chestertown). This was accomplished by using many software programs, including Google Sketchup, Google Earth, Geoweb 3D, ArcMap 10, Global Mapper 11, Jing and Camtasia Studio. By using data from these programs, the team was able to bring full 3D images of buildings with georeferenced light poles, building polygons and trees to build a rich full 3D environment.


The focus of this project was to accurately represent Chestertown in 3D. This was done by compiling data on each historic building and taking detailed photographs of the accompanying buildings’ architecture. Using these images, each building was built from the ground up in a program called Google Sketchup. After the building was accurately modeled, it was placed on the matching property in Google Earth and exported, then brought into a program called Geoweb 3D. Using Geoweb 3D, the tree, light and polygon data, along with the 3D buildings, were incorporated into the program to create a living scene that modeled the Chestertown Historic District. Students and staff gathered real tree and light data, and then placed the corresponding points on the exact spots in which they were located. These were bundled together in files in ArcMap, where they could then be used in Geoweb 3D to place 3D trees and lights.


Through the combined efforts of multiple students and staff members, this project brought together layers of data and files in order to create a rich full 3D environment that shows an exact replica of the Chestertown Historic District. The Chestertown 3D project has provided future opportunities for the lab to conduct similar projects in other towns, with Easton, Maryland already under way.
