LiDAR is an infrared laser mounted on an aircraft that scans the ground. It determines spot elevations for millions of map locations. 266,000 pulses per second are collected. Typical Lidar use is building Digital Elevation Models (DEM).

Today, the Florida Water Management Districts and other agencies are using LiDAR to map their entire management area. And it's cost effective for areas with light to heavy vegetation.

One foot contours can be developed and used to determine drainage basins and more. In most cases ACA procedures meet or exceed FEMA guidelines

LiDAR produces multiple points per square meter on the ground when using a high pulse rate sensor. ACA uses sensors ranging from 100 to 167 thousand pulses per second. With these we are assured of obtaining many hits to the ground within a square meter.

Final editing of the data is performed with a combination of photogrammetric and other tools. Photogrammetry is ideal for collecting all man-made features as well as the QA/QC of the LiDAR points. Digital delivery of the finished product is available in a variety of formats and media.

Environmental
False color IR film was the preferred choice to study wetlands and other protected areas for many years. With the introduction of digital sensors, there is more information available than ever before.

A digital camera can simultaneously provide three forms of image type: black and white, color and false color. The use of color and false color images is endless as it brings out signatures that are not visible in normal black and white photography.

ACA provides all forms of aerial products with both film and digital equipment. We've spent the past several years perfecting aerial flights specifically for these environmental concerns, including large protected areas of forestry, orange groves and coastal sea grass areas.

As always, it's the experience, dedication and know-how to deliver the right product for the right purpose that makes ACA the superior choice.
