Avoid risk in internet sourced LiDAR data

The availability of internet sourced LiDAR data seems to be a way to acquire high quality existing conditions data for a project, but many firms have found that using this data comes with a number of foreseeable but hard to quantify complications that can result in significant liability exposure. 

It is critical to make a thorough analysis of the original specifications for the dataset of interest, including the equipment used, its performance at the altitude used to acquire the data, the datum’s used to locate the data, classification schemes and even how stringent the control requirements used to adjust and place the data on the published datum’s was acquired. 

Few of those point clouds contain the hard information you need to analyze the dataset, but with some technical insight you can do enough homework to gain a level of comfort with data.

The purpose of this article is to provide you with some guidance in evaluating the validity and usefulness of that wonderful free LiDAR data you found on the internet.  Download this white paper below.

Would you stake your life on the accuracy of your map data?

Avoid the cost of erroneous information from out of date imagery & map features. Planimetric mapping is produced to show the horizontal positions of features. 

Tailored for the responsibility assigned to your office such as: 

Emergency Management - you need to ensure public safety so all transportation, addressable structures and water features, delivered in conjunction with a final database linking all addresses, phone numbers and road names to the map data. Data to aid in response and planning.

Utility Management in Public Works we can identify valves, manholes and catch basins to aid in planning and design.

Building data can be used for growth analysis and 3D modeling. Building pavement data can be used for impervious surface analysis.

Make informed decisions with map data that shows the horizontal positions of features. 

Whether you need a planimetric update or new planimetric data layer contact us to discuss your project.

Flood Hazard Mapping

For facility managers who need to stay on top of day-to-day maintenance and even critical situations, combing planimetric mapping with topographic data helps determine the flow direction of a potential hazardous spill and other potential hazards such as flooding.

NOAA is predicting that sea levels are rising twice as fast as projected when most nuclear plants were built.  After the 2011 Fukushima Daiichi Nuclear Power Plant incident in Japan, U.S. nuclear facilities are now required to update their plans to address potential flooding events.

We recently completed a Nuclear Plant project for a firm that was focused on planning and analysis of potential flood hazards.  The analysis required detailed topographic and orthophotography deliverables.  Acquisition needed to be during leaf off conditions, with no clouds and captured within +/- 2.5 hours of low tide.  Using our Trimble 68i LiDAR mapping system, we captured LiDAR & imagery simultaneously. 

Assisting engineering firms and their clients with the geospatial data to assess the safety and analyze severe flooding scenarios and their impact on the community, contact us to learn more.
