Our Colour (RGB) Orthophoto - a high-quality image that is colour-balanced and seamlessly stitched together. With an accuracy of +/-15 pixels and 8-bit bit depth, this product is perfect for a range of applications. Plus, our null data value is set to 255 (white), ensuring that the image is clean and free from any unwanted artefacts.
Our DGPS photo centres have an accuracy of 0.5m in XY, making sure that the imagery is precise and accurate. And with two different formats available - Geotiff or ECW with 10:1 compression or 1km x 1km or 5km x 5km tiled format - it's easy for you to choose the one that best fits your needs. Our tiled imagery is even aligned with the MGA grid and named to the top left coordinate.
We also provide you with a photo centres table, including all the relevant information like image names, latitude, longitude, and height in WGS 84 format. And to make your life easier, our project metadata file includes all the essential information like time of capture, flying height (AGL), forward and side overlaps, sensor used, focal length, pixel size, datum, and coordinate system used (GDA94/MGA or Geographic WGS84).
Trust us to deliver high-quality orthophotos that are accurate, seamless, and perfectly suited to your needs. Don't let your imagery fall short, upgrade to our Colour (RGB) Orthophoto today.

Example Images
Photogrammetry is a technique that uses aerial or satellite imagery to extract information about the earth's surface.
One important factor to consider in photogrammetry is the Ground Sampling Distance (GSD). GSD refers to the amount of area on the ground that each pixel in an image represents. The higher the GSD, the less detail that can be extracted from the imagery. Conversely, the lower the GSD, the more detail that can be seen.
This means that smaller objects or features on the ground can be identified with a lower GSD. Therefore, it is necessary to carefully consider the desired GSD when planning a photogrammetry project to ensure that the necessary levels of detail are captured.
