Jonas: Currently, we experience a great transfor 
mation from the analogous to the digital era, as 
well in all fields of hydrography: Measurement 
technology, data processing, the product itself 
and in sales. That's what the term means. 
HN:What is your attitude toward paper in this dig 
ital era? 
Jonas: I grew up in a low-stimulus country. As 
a child I used to read a lot and definitely I am a 
»book person«. In the end, paper is a medium with 
advantages and disadvantages; it doesn't need 
electricity. You can read the newspaper in the tub. 
The printing resolution is very good. For a lot of 
information, paper is a very good medium, which 
on top doesn't cost a lot. However, for distributing 
ever changing geoinformation fast enough and 
across great distances you need a digital medium. 
HN: Do you think the printed sea chart can still be 
improved? 
Jonas: Maybe the cuttings of sea charts can be 
individualised. The current cutting is always a re 
sult of balancing the manageable total amount 
of charts of an area and the desired detail of the 
resulting scales. In order to solve this compromise, 
a procedure would be necessary with which you 
can select a certain area from a database and 
print it on paper according to a true to scale au 
tomatised generalisation. If you stick to the chart 
contents that
