Orthomosaics are aerial top-down 2D maps made by stitching together many photos to form one image through the process of photogrammetry. They can provide data covering large areas, and since an orthomosaic is georeferenced, it is perfect for exporting into GIS software as a basemap or other layer.
What are Orthomosaics Commonly Used For ?
- Producing 2D aerial images of an area that are accurate and measureable (distance and area)
- Documenting progress on a project
- Exporting into GIS for map making
- Showing properties of an area (i.e. vegetation, heat loss) with the use of various sensors and cameras
- Giving an overall aerial view of an area
- Planning recreational facilities such as playgrounds, bike parks or trail networks
- Anytime greater detail than google earth can provide is needed, or if online data is not to date
An orthomosaic is one large image made by stitching together smaller images. Orthomosaics created from drone photogrammetry are corrected for lens distortion and the curvature of the earth. Precise measurements can be taken from them, as they are georeferenced. Perfect for export to GIS.
