Photogrammetric Mapping

Photogrammetric Mapping

Photogrammetric Mapping

The two major features of Photogrammetric Mapping are Planimetric and Topographic Mapping. Planimetric mapping includes and identifies physical features such as roads, buildings, and vegetation, while Topographic Mapping is a collection of break lines and spot elevations. This method of mapping is a primary source for the creation of Digital Elevation Models (DEMs) and Digital Terrain Models (DTMs). Williams Aerial & Mapping, Inc. has over 100 years of experience creating both planimetric and topographic maps.



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.

LiDAR Collection

LiDAR Collection

Power companies take notice! Need LiDAR for your transmission lines? Think that the helicopter platform is the only way to get the point density you need? Williams has modified single engine, slow flying, fixed wing aircraft to run our LiDAR sensor. This combined with the high speeds achievable from the sensor itself will provide the point densities you need at a significant cost savings. Contact us today to discuss.

Our array of state of the art sensors allow us to acquire emulsion, digital and LiDAR data for your projects, on your schedule. Take a look at the variety of sensors we offer to see how we can accommodate your needs. Click here for more information.
