Geospatial Data Collection
DC May Company staff is responsible for the design, construction, maintenance and use of specialized mobile data collection equipment used to document traffic sign and pavement marking inventories. The equipment utilizes multiple high resolution (5MP) digital cameras, LiDAR imaging and sub-meter GPS recording equipment to document traffic signs and structures. The images are collected at a rate of five frames per second to allow data collection at normal driving speeds. The images and GPS data is displayed and recorded using custom software. This allows the continuous monitoring of data as it is collected to ensure quality and completeness of the data set. The software also displays the routes within scope and creates a track log of roads traveled to document the data collection process. This provides improved efficiency and accuracy of the data collection process.
The equipment is designed to be self-contained and portable. This allows the equipment to be deployed on short notice, and enables the use of multiple data collection units when project size or timing is critical. Another advantage of this approach is eliminating the need for a dedicated vehicle and resultant mobilization and depreciation costs.
Asset Inventory and Assessment
After the data has been collected, we deliver the inventory through 3M's Asset Management Software. This allows the client to access the database from a web browser as well as providing a tool for field assessments and continued editing. Some examples of inventoried assets include traffic signs/signals, pavement markings, guard rails, curbs, lighting/utility poles, and parking meters.
The log record includes atributes such as:
⦁ GPS Coordinates
⦁ MUTCD Code and Description
⦁ Sign and Post Condition
⦁ Post Type and Material
⦁ Digital images of each sign
⦁ Digital images of night assessment and more!
The software is also designed to create work orders, generate tailored statistical reports, and view past and future maintenace records. It offers easy-to-use navigation tools that allow you to quickly explore your assets in a host of different ways, including a triview mode powered by Google.
But we also understand that each client has their own specific needs, and the data we collect can also be used to populate other industry standard commercial software.
Drone and Lidar Scans
DC May Co. is a licensed commercial drone operator, and as such can provide a range of services. We can create anything from simple photographic documentation to highly detailed 3d meshes and textures from Photogrammetry based scans. We can also capture elevation reports, land surveys, and high definition video.
Lidars can be mounted on vehicles to create an accurate point cloud of any environment. Once the Lidar data is captured, we can measure inventoried assets down to fractions of an inch. Contact us to see how the added Lidar scans can benefit your project.
