HydroCharting ApS Survey Utilities


The utility program HYDROBIB is meant to be used as a “knowledge database” for placing various information and “hydrographic tools” that I by experience know will come in handy from time to time.

The intention of the HYDROBIB utility is to be used for classroom sonar/hydrography training etc.


The software is provided as “freeware”. I cannot guarantee or assume responsibility of any of the calculations or information provided in HYDROBIB.

If you have comments or suggestions, you are most welcome to give me a call or send an email.
