Thanks, DroneDeploy´s blog is indeed quite interesting and rich in information. Unfortunatelly, blured or distorted areas in large mapping can also happen due to bad stitching and not only from bad image capturing. But it´s improving fast and overall is quite reliable.
Yeah as I say, we can´t control stitching because it´s cloud-based (most of the time anyway). But the article has it right that we can do our best to ensure good quality data to feed. Whetever increases our chances to get the best result possible, right?
