DescriptionSensors incorporated into mobile devices provide unique
opportunities to capture detailed environmental
information that cannot be readily collected in other
ways. We show here how data from networked navigational
sensors on leisure vessels can be used to construct
unique new datasets, using the example of underwater
topography (bathymetry) to demonstrate the approach.
Specifically, we describe an end-to-end workflow that
involves the collection of large numbers of timestamped
(position, depth) measurements from "internet of
floating things" devices on leisure vessels; the
communication of data to cloud resources, via a
specialized protocol capable of dealing with delayed,
intermittent, or even disconnected networks; the
integration of measurement data into cloud storage; the
efficient correction and interpolation of measurements
on a cloud computing platform; and the creation of a
continuously updated bathymetric database. Our prototype
implementation of this workflow leverages the FACE-IT
Galaxy workflow engine to integrate network
communication and database components with a
CUDA-enabled algorithm running in a virtualized cloud
environment.
