Using drones for mapping can be very useful for a variety of different reasons. The process involves flying over a specified area at a specified altitude to collect numerous photographs and associated data. Post flight processing of the data results in the mapping products that can serve many purposes. The “maps” created by the process are actually large, smart pictures that contain elevation, distance, and location data; and they can be presented in different formats for viewing. The low flight altitude provides an incredible amount of resolution, so even small details can be seen on the “maps”. Distance, volume, and area measurements can easily be taken from the “maps”; and elevation data can be viewed and measured as well. The applications for this technology are far reaching, because it provides current data that is easily accessible and affordable.
Ortho maps have numerous applications, and our maps provide flexibility and quality that has traditionally been cost prohibitive. Our orthos show more detail because of our lower flight altitude. Our high quality cameras also contribute to the detail in our maps. The flexibly comes in our ability to shoot and create a new map at any time. This is very useful in tracking and illustrating changes that occur in the mapping area. Our maps can be used to easily calculate area, distance, and volume.
In addition, we provide all the native photos as part of the deliverable. Each photo has embedded EXIF data which gives the specifics on the date the photo was taken, GPS coordinates, altitude, resolution, and more. The combination of pictures and associated data are perfect for documenting a site.

Digital Elevation Models
Digital elevation models give a quick look at elevation data through color coding. This can be useful to get an overview of the relative elevations associated with the site. High spots, low spots, drainage issues, and the general grade can quickly and easily be observed when using these models.
The ability to assess a site using a digital elevation model is especially helpful in tracking and documenting changes during the development of a property. It’s also very beneficial for drainage and erosion inspections, documentation, and tracking. And, it can be a great tool for site planning or pre-sale site information.
Although a 3D model is a cool thing to look at, it serves a more useful purpose for many companies. 3D models can be a great visual compliment to traditional contour data, and they give the ability to revisit the site to see things that contours, pictures, and faded memories can’t. Equipment, materials, painted markings, and more are documented and available in a 3D model even when they no longer exist on the site.
Not only can 3D models take the viewer back in time to see what was, they can also allow a viewer to see a current view without ever stepping onto the site. Unlike video or photographs, 3D models are interactive and the viewer can focus on what they want to see, and go where they want to go within the model. It’s a great way to visit a site without traveling to get there. This provides some new and unique opportunities for the construction industry and for commercial real estate.
Take a spin in this example. Once the play button is pushed, icons will appear in the lower right corner of the screen. These options will help you use some of the tools available to get more insight on the model. Use the Viewer Mode icon to help navigate the model. It the “First Person” mode, use the “W”, “A”, “S”, and “D” keys on your keyboard to zoom in and out and move left and right. Use the mouse to look around. The mouse wheel will help zoom in and out in the “Orbit” mode. For more help, use the icon in the lower left corner of the viewing area.
