Rectification Error #99

Closed CameronBodine closed 11 months ago

Issue with rectification. Looks like an issue with range calculation. I think I have seen this before. Something to do with how PINGMapper handles when auto range changes.

Yes I think it's how the max range is determined for each chunk.

Check load son or get scan chunk functions.

Fixed it. Need to call _getScanChunkSingle() when loading sonar data into memory. This function then calls _loadSonChunk. If not, then the maxPing isn't calculated and will use the maxPing in memory, which may be incorrect if the range changes throughout the recording. image
