Abstract: Compiling a bathymetric product to be used in nautical charts has always been complex and time-consuming. This article will focus on determining possible bottlenecks that hinder this process, and possible solutions that currently exist to reduce times in obtaining a quality final product. The results are based on the analysis of a complex compilation case study, as well as through surveys conducted among different IHO hydrographic agencies. Final chart sounding selection and depth 
contours generation still prove to be the most challenging tasks. Although there is decent research to improve both processes through their automation, it seems there is still much room for improvement. Additionally, building and managing a bathymetric database to obtain a single reliable bathymetric source for more efficient bathymetric compilation, emerges as an important issue that concerns most of the hydrographic community.
