Continental Mapping offers a complete, off-the-shelf asset management solution. From field collection and data processing to data hosting, Continental Mapping provides clients with the data needed for authoritative and accurate asset inventory.
Continental Mapping provides a street level imagery solution to allow departments to view, inspect, measure, and capture the position of features and physical assets in the right-of-way and buildings that face the street. Combining high-resolution 360º imaging, high-definition lidar, and an integrated position and orientation system, the Continental Mapping mobile lidar system for asset grade applications is an efficient and accurate mobile data collection system. One of the unique benefits of the sensor is its incredible portability. The entire system weighs only 19.5 lbs. and can be mounted on any vehicle with a raised roof rack, making it simple to remove and mount on another vehicle if necessary.
With six industrial-grade 5-megapixel cameras integrated into the body, Continental Mapping’s asset grade sensor provides reliable 360º panoramic imagery coverage ideal for asset management. The unit, with the built-in camera system, makes verifiable assets a reality – network wide.
All images are also geocoded and linearly referenced, allowing all data to be seamlessly brought into ArcGIS and ArcMap.
In addition to 360º panoramic imaging, the sensor typically used by Continental Mapping for asset projects is also equipped with a Velodyne HDL-32E lidar sensor. Lidar (Light Detection and Ranging) is a surveying technology that measures distance by illuminating a target with a laser light. The resulting lidar dataset goes beyond basic inventory and can be applied to an advanced budget and maintenance plan.
The main advantage of lidar, outside of the accuracy, is the type of assets you can inventory. Photo imagery allows you to do a decent job of collecting point features; for example, a sign is located at mile point XX with XYZ GPS location. However, lidar allows for adding linear and polygon asset features, such as linear paint stripes or polygons of the asphalt surface area. Lidar also provides the ability to collect intensity from reflective material, like paint striping, allowing for automation in the collection and a condition assessment of the asset (high intensity correlates with good condition).
Additionally, lidar provides some unique attributes that photo imagery will not, including the vertical and horizontal clearances of overhead structures, along with power lines and vegetation encroachment on the right-of-way. With a lidar dataset, the second time a citywide inventory is performed, the point clouds can be compared, allowing us to perform a change analysis. This is an accurate way to see if the asset has changed or a new asset was introduced from the last collection.
