- Filligree 7y agoThat's how it's already phrased in the law, but it isn't a practical rule for DJI to implement. Maps aren't detailed enough, so they'd have to put ground radar in the drones, which wouldn't work... Or they'd just reduce the max altitude above launch site limitation already in their firmware. An easier-to-implement limitation that stays within the legal restrictions.
- nwallin 7y ago> Maps aren't detailed enough, Yes they are. All of the US is mapped to 3m horizontal resolution and 1m vertical resolution, the world to 15m. This is grossly overkill. A 30m lossless compression dataset will run you about 1GB, which is plenty for this purpose. It's free too. https://terra.nasa.gov/news/aster-digital-elevation-model-version-3-released https://terra.nasa.gov/news/aster-digital-elevation-model-ve...
