Over the last years, scientists and professionals have made available several free and open-source software tools meant for geophysical survey planning, underwater remote sensing data processing, and geospatial data visualization. However, the use of these tools is limited within hydrographic offices. One of the reasons could be the lack of awareness about the functionalities and the performance of the available solutions. The purpose of this paper is to present an overview of free and open-source tools that may be applied to a Hydrographic Office workflow including data acquisition, data processing, quality control, and data visualization.
