At ๐๐๐๐๐๐๐.๐๐๐๐ we process thousands of images each day to produce high-quality Orthophotos, DEM, and Point Cloud, with maps ranging from less than a square kilometer to over fifty square kilometers and have been asked by many surveyors on how to ensure good quality outputs, Our answer is simple “๐๐จ๐ฎ๐ซ ๐๐ฎ๐ญ๐ฉ๐ฎ๐ญ ๐ข๐ฌ ๐๐ฌ ๐๐จ๐จ๐ ๐๐ฌ ๐๐จ๐ฎ๐ซ ๐๐ง๐ฉ๐ฎ๐ญ๐ฌ.”
The success of your drone survey project will ultimately depend on how accurately GCP and feature marking are performed, which is entirely reliant on the ๐ช๐ฎ๐๐ฅ๐ข๐ญ๐ฒ ๐จ๐ ๐ญ๐ก๐ ๐ข๐ฆ๐๐ ๐๐ซ๐ฒ ๐จ๐๐ญ๐๐ข๐ง๐๐.

The tool you use to collect data is arguably the most important aspect. You don’t need the most expensive, highest megapixel camera available, but there are some minimum requirements to ensure you’re collecting the best data possible.

Our best friend and our worst enemy
We canโt control the weather, but at the very least, try to fly during consistent lighting conditions. Changing lighting conditions will create an Orthophoto that might look undesirable.

The brighter the lighting outside, the less time your shutter needs to be open to produce a properly exposed photo. The issue may arise when there is insufficient lighting and the drone’s speed remains constant.
