Contour Map of the Island of San
Salvador in the Bahamas.
The model was created using ArcView 3.3 and
the Image Analysis Extension. A topographic map from the United
Kingdom was scanned in pieces and "cleaned up" in Adobe Photoshop.
The image was loaded into ArcView using Image Anlysis and the contours
were hand digitized using ArcView. The polyline data and verticies
were converted to points using another extension. The points that
now had a Z (elevation) value was used to create a Triangulated
Irregular Network (YIN) and a Digital Elevation Model (DEM). This
was done using both ArcView and Global Mapper 14.
San Salvador
Island is where Christopher Columbus made his first landfall in "
The New World" in 1492. It is an incredible place to visit.
