William's orthos are unsurpassed in image quality. All ortho projects are mosaicked, even with multiple flight scales, resulting in truly seamless imagery. Whether you have a corridor project or annual stockpile updates, Williams' experienced staff has the skill to ensure your job is done with extreme levels of accuracy.
Williams has produced orthophotography for various types of engineering firms with projects ranging from, but not limited to, quarries, nuclear sites, corridors, as well as more than a quarter of Indiana's counties. All orthos are produced in-house here at Williams Aerial & Mapping, Inc. We have delivered quality orthos with pixel resolutions ranging from a quarter inch to two feet.
Orthophotography is commonly used as base maps in the Geographic Information System (GIS). These maps are compiled with the collection of aerial photographs, which are oriented through trigonometric processes and then molded to the ground elevation data you prefer. After this process is complete, the final product is what is known as an Orthorectified Base Map.
Aerial Photographs inherently contain distortions as a result of factors such as, the sensor's orientation at exposure, surface relief and lens distortion. In an orthophotograph, these distortions have been removed.
Some common applications for orthophotography are Base Maps for GIS, Urban Planning, Watershed Analysis, Civil Engineering and Environmental Assessment. Key benefits and applications of these maps are that they are easily interpreted, they allow direct measurements of distances, areas and angles, and that more features are shown than what are practical to capture on a vector map.
