Why Orthophotography?Why Orthophotography?
Orthophotography has the geometric characteristics of a map and the image qualities of a photograph. These qualities allow for:
distance measurements
area calculations
determination of feature shape
direction calculations
determination of coordinates at a given location.
What is Orthophotography?What is Orthophotography?
A digital (electronic) aerial photograph that has been corrected to remove distortion from the camera & airplane movement and adjusted to fit the ground surface.

Elevation ProductsElevation Products
Digital Surface Model (DSM) Digital Elevation Model (DEM)
DEMDEM A DEM is a series
of points which have X,Y,Z coordinates.
DEM’s are used to correct relief displacement (ortho-rectify) in the imagery.
Without further processing, the DEM can hold 10’ contours
With further processing, the DEM can be used for 2-foot contours.
Uses of Color-IRUses of Color-IR
Mapping and feature extraction of water bodies, wetlands, impervious surfaces, and land cover.
Useful for applications such as drainage management, land cover mapping, and water quality.
