German Depth Data #186

Open quantenschaum opened 6 months ago

You may want to use depth data provided by the german BSH as OpenData.

The data can accessed via the GeoSeaPortal as WMS.

The endpoints containing contour lines and areas are

To get an overview of what to expect, just plug these into the ArcGIS online viewer together with OSM tiles and it looks like this.

The data is up to date and is exactly what is shown in the official nautical charts.

IMHO the right way to get proper depth data into OSM is to import/use these datasets. It's very brave trying to survey the 7 seas again as a crowd project, but I think in reality this is pointless and unfeasable. The data is already there, payed for with tax money and partly available thanks to OpenData. Just use it.

When the project was founded, open data was more a vision than reality, but things have changed.

I agree fully,where it comes to Germany, the BSH data should be accessible as a layer. I wonder though what we can do for other regions. Any opinions @stevo01 @quantenschaum ?

Since the hydrographic offices of the different countries supply data in various formats or not, I would create some framework to gather the data, transform them into a common format and compile a depth layer from it. This should be fully scripted and could be run in regular intervals to update the data.

You cloud also add a layer with depth data from https://ows.emodnet-bathymetry.eu/

It could look like this (color map was inverted)
