I intend to use the data acquired by my surveys to create local detailed charts for dredging operations for my yacht club. But, the long term is to use the info to create high resolution local charts wherever I explore, and to upload them to the cloud.
Are you going to upload to Openseamaps.org? Or where in the cloud ...

Re: Fishfinder for dinghy

I finished the installation this afternoon and did a sea trial. All works well. I need to pick up an SD chip to begin actual bottom recordings, and I have to complete my registering with Insight Genesis. I just learned about openseamaps.org from your posting, but since I am still in the early stage of learning, I won't be posting any maps for a bit until I am more proficient. This whole concept of map making for shared use is terrific.

I totally agree! If the equipment is compatible, uploading should be easy. And since you are the owner of the soundings, you can upload multiple places.

I am considering to upload to both Navionics as well as Openseamap.

In Hong Kong, it is of particular interest. The local marine department has decided that no third party may use the data. All paper and electronic charts can only be from them. That is the only place in the world, but for Hong Kong, I am not so surprised: Many departments are working in a very backwards way:

Electric bikes of any kind are not allowed (3 months in jail first offence)
Tesla Model S: No third row seats, web browser and it took 6 months to get the auto pilot functions "approved" (everywhere else it is).

So I just say forget it, I am not paying 200 USD a year for chart services, for those few trips I do. I will stick to my 10 year old charts, and supply it with either Navionics, OpenSeaMap.org - or both.

A lot of work must be done, but since there are boats sailing all over the place, it's just a matter of logging when you are sailing anyway. I can't wait to map out our marina, and the surroundings. The data will be much more detailed than official sources.

Re: Fishfinder for dinghy

I was planning to use the Navionics Sonarcharts feature to make my dink a pilot boat. The Hummingbird 4 Pro and 5 Pro both have the requisite GPS+SONAR+WiFi.

I don't plan to replace my charts and MFP with an Android tablet that has charts I just made but I do plan to use an Android tablet (with charts I just made) to scout for SCUBA spots and anchorages and passages for the sailboat.
