OPTECH 1210 LiDAR System

Imagine a mapping product that gives more detailed information, better quality, and a faster turnaround because it can be done in less than ideal weather conditions.  Light Detection and Ranging (LiDAR) or airborne laser mapping is the technology of the future and Optimal Geomatic is one of a handful of companies with LiDAR Technology in place now. When coupling LiDAR with our state-of-the-art Leica LH Systems RC-30, Airborne GPS, inertial measurement units (IMU) company owned aircraft, our skilled Aerial Photographers and Pilots, Optimal Geomatic clients receive the best  possible mapping product available today.

 Key advantages of the Optimal Geomatic ALTM 1210 LiDAR system include:

•    Environmentally sensitive

•    Non-intrusive (no need for right-of-entry for survey)

•    Significant schedule acceleration achievable compared to traditional mapping project

•    More economical

•    Can fly anytime – day or night – 365 days per year

•       No sun angle requirements

•    Can penetrate certain types of vegetation

•        Leaf-off conditions not required

•   Among the features specifically included in Optimal Geomatic’s ALTM 1210 LiDAR system are:

•   Scan frequency up to 10,000 Hz

•       Increases number of ground coordinate “footprint” locations

•       Minimizes “footprint” size

•   Variable scan angle up to 40°

•   Flight altitudes up to 6500 feet

•       Optimizes LiDAR swath width as a function of project requirements and economics

•    First pulse/last pulse

•       Distinguishes vegetation cover from terrain

•    Intensity data

•       Allows for real time “imagery” in support of preliminary alignment and grade design

•   Accuracies to better than 6”

•       Supports ASPRS Class 1 requirements for projects requiring 1’ and 2’ contours

One of the primary keys to Optimal Geomatic’s success with our LiDAR technology is in our strategic approach to how we collect and use LiDAR data.  Our approach to LiDAR starts in how we acquire the LiDAR data and ends in the uniqueness in the LiDAR product we deliver to our clients.

From the data acquisition phase, Optimal Geomatic’s approach is centered on the ability to simultaneously acquire photo and LiDAR data with our custom-modified dual sensor aircraft platform.  Optimal Geomatic flies a Piper Navajo specially configured with two equipment ports – one for our RC-30 precision aerial camera and the second port for our ALTM 1210 LiDAR system.  Once acquired, LiDAR data receives preliminary post-processing in the field as a field QC check to ensure data integrity.

Another of the key advantages offered by Optimal Geomatic’s LiDAR capabilities is in how Optimal Geomatic provides LiDAR data to our clients.  Our approach to LiDAR data is that LiDAR data is not a complete solution unto itself, but rather a photogrammetric tool that is part of a much larger and comprehensive photogrammetric solution.  By design, Optimal Geomatic’s deliverables to our clients are not massive LiDAR data sets, but instead include LiDAR data into digital ortho photographs for a more complete and meaningful solution that meet and exceed our clients needs.  Few mapping clients find that they have the time or technical expertise to analyze or merge LiDAR data into mapping products.  This unique approach taken by Optimal Geomatic affords our clients the ability to receive a quality, turnkey, comprehensive mapping solution in a very timely and economical manner.

LiDAR is quickly becoming the preferred acquisition choice for elevation data because the quality and detail resulting from this new technology far exceeds conventional methods.
