An Orthomosaic combines all pictures taken throughout the survey to create one geometrically corrected image.
Unlike a standard aerial photograph, an orthomosaic corrects a number of different distortion factors including the earth’s surface. The resolution is significantly higher than a traditional aerial photograph and the image is scaled correctly, allowing measurements to be taken from it if desired.
The image above shows an orthomosaic overlaid onto a standard satellite picture. The significant improvement in detail is clear at this zoom level, but we can attempt to demonstrate the achievable detail by drawing your eye to the area highlighted in blue.
Below is a magnified section taken from the same image, zoomed into the area in blue, which shows the vast improvement in detail that can be achieved through the orthomosaic.
