Thanks! That's helpful. I should clarify that the primary purpose for the bathymetry is for ecological assessments and most of the analysis will use ArcMap. So I guess I need to confirm if this will work:
- a somewhat portable Lowrance unit and mounting hardware for canoe/kayaks
- survey using 40-80m transects (note that we won't need 100% coverage and can likely get away with 50% - I'm assuming that the reefmaster processing will infill/extrapolate?)
- process with Reefmaster to produce Arc-compatible vector and raster layers
- upload the data onto a crowd-sourced site for ease of public distribution (what gets uploaded - raw sonar files or the processed files?)
If this seems like it will work, what specs should I be looking for on the sonar unit and transducer?
Thanks again for your help.
Cheers
