I will tell you how a hydrograph works with professional hydrographic
software and as a
C-MAP partner.
All public projects to collect depths do not work! They became extinct after the opportunity appeared to make personal depth maps in their
chartplotter.
The big problem is that the incoming data have large errors due to the high level of the measurement, the chaotic lines, the lack of popping on the
water level.
In most cases, the data came only from the
passage of a navigable
passage, no one intentionally will not squarely measure the specific territory.
In particular, those who make a detailed measurement of the territory do not want to publish data for open access.
C-MAP Genesis.
Navionics SonarChart. Basically it's Fishermen. Large data sets are set only by those who are sponsored by
Navionics and C-MAP.
Now the plugin is completely self-contained, it is quite suitable for collecting hydrographic data. Thanks to Rasbats for the added functionality.
From the wishes, the possibility of building bathymetry in real time and in manual on the basis of the measured data. There are many examples.
