3D Perspective View Samples

May 6, 2005/in 3D Images, 3D Modeling, Digital Elevation Models

The following images are examples of perspective view models that were generated from a 2 meter LIDAR DEM integrated with 50 cm digital orthophotography of Port Lorne, Nova Scotia. Port Lorne is a coastal community along the Bay of Fundy with a relatively steep terrain so the images represent different perspective views depending on the source of origin and the direction that they are facing.

The colored arrows on the key image to the right represent the different perspective views that were generated from different locations and viewed along different directions (displayed in the images below). This image of the area also represents the traditional GIS view from above, as discussed above.

The first image below represents a perspective view (red arrow) of the area if it were viewed from the center of the image, above the wharf looking in an easterly direction.

The next two images below represents a perspective view (blue arrow) of the area if it were viewed from the upper right hand corner of the original image in a south west direction. The images that demonstrate the same perspective but have different types of LIDAR DEMs integrated with them allowing them to portray different data within them.

The next two images (first one represented with the green arrow, second one in blue) represents a perspective view of the area originated in the upper left hand corner of the image, but in slightly different directions.

Map created showing New Brunswick high precision monuments within and around 2003 AGRG LIDAR project study areas used to help plan LIDAR validation surveys.

Color Shaded Relief Models – Cap Pele, New Brunswick

February 24, 2004/in 3D Images, 3D Modeling, Digital Elevation Models, PCI Geomatica, Remote Sensing

The two images above represent artificial three dimensional perspective views perspective views from different points of origin featuring color shaded relief models that were created from high resolution LIDAR digital surface models as part of a LIDAR flood modeling graduate research project.

The study area for the project consisted of the coastal Gulf Shore region of southeastern New Brunswick from Kouchibouguac National Park south to Jourimain Island (location of the Confederation Bridge). The coastal zone of New Brunswick is a picturesque fishing region that boasts several kilometers of sandy beaches with some of the warmest salt water temperatures north of Virginia.

LIDAR surface modeling of Bouctouche New Brunswick

November 27, 2003/in Digital Elevation Models, LIDAR

Color Shaded Relief (CSR) image generated from Bald Earth LIDAR points on the left, Middle image is of a Digital Surface Model generated with “All the LIDAR points” and on the right is an air photo for the same area. The area shown in the data samples are of Bouctouche in New Brunswick at a scale of 1:6000. Data sets were part of my gradute research work at the AGRG / COGS in 2003.
