Marine and Coastal Mapping (Shoreline, Wharfs, Bridges)
When needing to inventory features in the near-shore environment along beaches, harbors, and riverbanks, the TITAN solution has particular relevance. There are two main application areas for this configuration: Environmental, and Engineering and Planning.
Environmental
The interface between the land and water is often a very sensitive terrain which is difficult to access for the purposes of data collection. This includes beaches and riverbanks which are frequently monitored for erosion and change detection. Some beaches are the subject of a very high level of monitoring because they protect either sensitive habitat or high-value real estate. Rocky shores are also particularly difficult to access for data collection by any land method.
Being able to collect dense, accurate LiDAR data from a shallow near-shore area can provide a very important data source. Collection of subsurface areas is frequently done using near-shore bathymetric technology. The shore area can be collected by a vessel mounted system. Merging the terrestrial and bathymetric data provides a valuable data set that can then be used for environmental monitoring and analysis.

Engineering and Planning
This involves collecting data in a harbor or river area and inventorying features and structures along the shore. Docks, bulkheads and other facilities of this type are frequently difficult to access and the TITAN solution solves this problem. The area under docks is frequently the subject of great interest, since it often has many changes occurring over the years which are not recorded. Where under-dock vessel access is possible, TITAN provides a method of inventorying the location of all the utilities under these structures which have been added, modified and abandoned over the years. This information is very important prior to any work being done on these structures. The exact location of pilings under docks and waterfront building is an important type information that is difficult to collect and often goes unrecorded.

TITAN® Variants recommended:
TITAN Offshore is designed to provide a fast and accurate means of surveying shorelines and related facilities. The system is a rugged, long range scanning solution designed to be mounted on a seaworthy vessel. These surveys have always been a challenge, but TITAN Offshore provides a fast and accurate method of collecting data while still operating in navigable waters. For the first time, it is possible to combine detailed shoreline terrestrial LiDAR with near-shore bathymetric data, especially in tidal waters. TITAN Offshore provides the link that enables the creation of an integrated model from near-shore to on-shore.
This system provides a fast and effective vessel-based means of surveying shoreline facilities such as docks, coastal areas, and offshore oil platforms. There is no other comparable solution to accomplishing these surveys in an efficient and timely manner. This Variant will be equipped with a single, long-range and side-looking scanner, and has components optimized for working in a harsh marine environment. Federal engineering agencies, design and construction engineers, port authorities and other similar agencies have the need for this solution.
TITAN Long Range is designed to provide fast, safe and accurate surveying of surface mines and other challenging situations where a range in excess of 300 meters is necessary to accomplish the project. The horizontal and vertical accuracy of the acquired data meet the requirements for this type of survey. The rapid collection provided by this rugged system enables time critical surveys which were impossible in the past using conventional methods. These surveys are done at the fraction of the cost of traditional surveys and with greatly increased safety to the survey crews.
This variant of the system uses long range lasers on one or both sides. This enables the system to collect data at ranges in excess of 300 meters depending on the reflectance of the target. Compelling applications for this version include surface mining, where scans of spoil piles, tailing ponds and mine faces need to be performed rapidly and with low risk to survey crews. In the past it was not possible to scan mine faces regularly using traditional techniques. A closely related application is the collection of steep slope areas along highways and rail lines where this type of data is critical to modeling the risk of areas for rock falls, and other similar hazards.
