Mapping & 3D Modeling

Georeferenced Photo-orthomosaic Imagery of Your Job Site or Property

HI-Site Aerial Services can map your property, job site, or infrastructure to create orthorectified imagery. Series of high resolution nadir images are stitched together to create photo-orthomosaics. Think of it as a very large panoramic photo looking straight down and spanning not only an X-axis (side-to-side) but also a Y-axis (up-and-down). Digital Elevation Models (DEMs), Digital Terrain Models (DTMs), and Digital Surface Models (DSMs) can also be created from highly sophisticated projective geometric algorithms for computation by means of triangulation of a point in space based on comparative analysis of the pixels of overlapping imagery.  A sparse cloud of these points is initially created and then further refined to a dense cloud of points over which a projective mesh is overlaid. that mesh is then assigned texture to create custom 3D imagery from oblique images. These advanced software solutions use a process called SFM (structure from motion) to render 3D models. Topographic maps can be created based on those same triangulation processes to create fairly accurate surface elevation and tree-height maps.

Have HI-Site Aerial Services LLC. create a to-scale map of your property and boundaries featuring hi-res imagery that is 10 to 15 times clearer that Google Earth imagery.

Mapping and drone imagery is great for architectural modeling, progress monitoring on job sites, topographic mapping of properties, infrastructure inspections, archaeological site and cultural heritage preservation documentation.

Drone surveys can create higher resolution imagery than satellites and common airborne survey techniques due to the fact that drones can fly closer to the ground to obtain a better GSD (ground sample distance). They fly at a slower pace, and are thereby able to capture more images to create higher image overlap. This also makes them a better solution for mapping small to medium parcels by offering finer control and cheaper acquisition costs. GSD is measured in area per pixel, so a 10 cm GSD would mean that one pixel in that imagery equates to 10 square pixels of  actual surface area. Therefore, a lower GSD equates to a higher resolution image. While satellite imagery typically offers  Typical Google earth satellite imagery ranges from 15 m to 15 cm of resolution. Traditional fixed-wing aerial survey platforms can push resolution as low at 5cm GSD. Drones can offer 1cm GSD and below. This amounts to much greater detail and ability to zoom in to the imagery obtained by drone photogrammetry methods to see your property or building site in high resolution.
