Laser Scanning and Lidar

Terrestrial LIDAR

ECORP strives to utilize the most current mapping technology and data collection processes. One of the most powerful and promising new data collection technologies is known as Laser Imaging Detection and Ranging (LIDAR). LIDAR data collection relies on an aircraft-mounted, computer-controlled laser that records high precision distance measurements, synchronized with a precision survey grade Global Positioning System (GPS) unit and inertia measurement system. As the aircraft passes over the study site, it has the potential to record high density x,y,z measurements that can later be interpolated into high density digital terrain models (DTMs), topographic contour data, and vegetation height maps. DTMs interpolated from LIDAR data provide an accurate data source for spatial analysis, terrain modeling, and change analysis.

ECORP provides access to LIDAR data collection for our clients by being the point of contact and liaison between the data collection vendor, ground survey crew, and aerial imagery provider. Also, ECORP can potentially help decrease our clients costs by combining collection orders to create bulk rate flights with lower project origination fees and aircraft ferry charges. LIDAR vendors used by ECORP produce elevation coordinates that meet or exceed National Map Accuracy Standards. LIDAR technology provides a cost-effective data collection method for documenting medium to large-scale archaeological features such as bedrock mortar complexes, mine tailings, water conveyance systems, and historic landscapes.

On a smaller scale, ECORP possesses desktop laser scanning capabilities to create three-dimensional models of artifacts, which can then be transformed into plastic models for use as educational tools, in interpretive displays, and to contribute toward preservation of information as part of a data recovery effort. These models can be scaled up or down to meet the needs of the client, and can be painted to replicate material type.
