Photogrammetry and Precision Land Mapping
Drone Media Imaging can survey land and development sites by collecting aerial image data at centimetre level accuracy for use in improving your planning, quality control, management of assets, and changes over time analysis, at significantly reduced risk and cost. Orthomosaic mapping techniques using accurate latitudes and longitude GNSS data from survey-grade GCP values will align your image data and stitched orthomosaic map to known locations in such viewers as Google Earth / Maps.
Satellite images are usually several years out of date and will only offer a certain level of detail, usually greater than 50cm GSD. With the deployment of drone technology to survey large land and property spaces, flying a grid at a detailed low altitude level, we are able to stitch together smaller detailed images that can be presented in 2D or 3D formats with GSD of 2.0 to 1.5cm or less.
Accurate surveys can generate contour maps and facilitate detailed measurement and volume data for use in quantifying materials for large scale developments.
