Ellicott City Flooding Animation

As you read in our previous post Ellicott City Flood Modeling, we deployed one of our Mobile LiDAR teams to Ellicott City, MD to capture post-event as-built conditions.  In addition to providing the County as well as State of Maryland agencies with the high-resolution LiDAR point cloud and spherical imagery, we took the opportunity to create a visualization of the observed 2016 flood levels overlain on a current 1:1 scale model of Ellicott City.  The resulting video (see below) was developed to aid residents as well as County and State Officials in their comprehension of observed water depths and inundation.

Ellicott City Flood Modeling

Following the significant reconstruction efforts in Ellicott City, MD resulting from the catastrophic flooding event that occurred on July 30, 2016 we saw the perfect opportunity to put our company tagline into action and Make a Difference.

Localized and micro-flood modeling analyses are perfectly-suited to capitalize on the high-accuracy terrestrial LiDAR and spherical imagery generated by our Mobile LiDAR systems, so with the assistance of our local Baltimore office we deployed a Mobile LiDAR team to capture the post-event as-built conditions and generate high-resolution data that could be used by County, State and Federal agencies.

Unfortunately, on May 27th, 2018 the unthinkable happened again just 22 short months after the previous flood, so we immediately jumped into action and provided County and State of Maryland agencies the collected data to aid planning and mitigation efforts to prevent future devastating flooding events. LiDAR and spherical imagery was made available through our innovative web-viewing environment (, which builds upon Orbit GT’s Publisher framework to create an interactive environment where stakeholders can navigate Old Ellicott City through spherical imagery, generate measurements from the LiDAR data, and interrogate 3D geospatial vector data in a seamless environment to base decisions and recommendations on a 1:1 scale model of the real world.

Stay tuned for our next post, where we’ll share an animated flythrough of the LiDAR data along Main Street with a simulation of the 2016 flooding.

Mitigating Beach Erosion

Like the majority of the country, Hurricane Florence has our full attention.  Devastating winds, torrential rain and elevated storm surge create a dangerous trifecta for our coastal (and inland) communities.  We're closely monitoring the effects of this storm on multiple fronts. 

First and foremost is for the safety of our staff, clients, and residents of the Carolinas.  Secondarily (and it's a distant second), we're watching the South Carolina coastline for lessened effects of beach erosion following the State's efforts to mitigate storm impact.

We are proud to have taken part in those initial efforts by deploying our LiDAR survey services in support of the cause.  Throughout the project Michael Baker's Mobile LiDAR team traversed over 250 miles of the South Carolina coastline to survey 300+ revetments and revetted seawalls using a mixture of Mobile LiDAR (riding on a modified UTV) and Static LiDAR for supplemental surveys.
