I am a new user of QGIS. I'm looking for a solution for my problem. I have my own dataset providing the latitude and longitude of different unique ID's. Now, I would like to classify those ID's that are showing on the rivers as 'on water' and those that are on land as 'on land'. There are thousands of data points, so manual classification is not possible.
Is there any way to load in some data of rivers, borders and/or coastlines in order to make classification like 'on land' or 'on river' possible?
I found a dataset providing the routes of waterways. Although this data does not show the true width of rivers, it might be useful as an example: http://nationaalgeoregister.nl/geonetwork/srv/dut/catalog.search#/metadata/2f58c248-b229-48af-a838-3279f7f0173c
