ORTHOMOSAIC

What is an Orthomasaic?

Ortho refers to photographs taken perpendicular to the earth’s surface, vertical or nadir. A mosaic results from combining multiple photographs. So, an Orthomosaic is the product of merging multiple vertical photographs.


Preservation in the most accurate way.

What is the purpose of an Orthomosaic? While similar imagery is readily available on the internet through computer apps the resolution/detail of that imagery is often inadequate for many uses. The imagery found on the internet is often not very current. The purpose of an Orthomosaic service is to capture current date, high resolution imagery.


How is an Orthomosaic used? Like many other applications for aerial photography, an Orthomosaic is used by residential and commercial property owners or for prospective property owners to assess details about the property that other imagery cannot provide. An Orthomosaic may also be used to perform asset or inventory management, regulatory compliance, and relative position of property features.


Is an orthophoto or orthomosaic a legal document? Typically, when used to measure accurate distances, aerial imagery utilizes ground reference control points for high precision position accuracy and the imagery is tied to know points on the earth’s surface or georeferenced. The resulting image is accompanied by references for how to interpret the information and is called a map. The process of producing a map is called photogrammetry. Land surveying involves setting property corners and establishing property boundaries for legal descriptions. A State issued license is required to practice the land surveying profession. If photogrammetry is to be used for land surveying, EagleView will partner with a registered land surveyor for the deliverable. There are many uses for photogrammetry other than land surveying. Meanwhile, an orthophoto or orthomosaic may serve the intended purpose without requiring mapping accuracy or can receive additional work for georeferencing to produce a map.
