DATASET STATUS - BIODIVALUE TRACKERS

HIGH LEVEL PROCESS – FROM AIS ANTENNA TO BIODIVALUE TRACKER

SCENARIO 1 - MANUAL UPLOAD OF HISTORICAL DATASETS INTO BIODIVALUE TRACKERS SPECIFIC TO LOCATIONHigh level requirements•Collate and update data as per established CSV format and guidelines•Upload and import CSV file directly to MySQL database feeding BioDiValue Tracker to refresh historical data available through web interface

Benefits•Most of the infrastructure is already in place•Limited know how transfer is required to update the system from time to lime

Limitations•Requires human intervention every time to manually update BioDiValue Tracker•Dataset available through BioDiValue Tracker will not be close to real time as in Scenario 2•Dataset quality is expected to vary as sources may not be automated as in scenario 2. •Seperate BioDiValue Tracker for every location in Sicily•No pre-processing of dataset to allow user to select vessel positions according to defined distance from coastline from BioDiValue Tracker•May give rise to inconsistencies when assimilating data sources for different locations into one BioDiWare software

SCENARIO 2 - NEAR REAL TIME UPDATE OF BIODIVALUE TRACKERS THROUGH AIS ANTENNA FEED

High level requirements•Setup infrastructure as in high level process described in previous slides using software and practices that are already in function for BioDiValue Tracker – Malta•Knowledge transfer from BioDiValue Tracker – Malta to implement in Sicily

Benefits•Automated process from data capture through AIS Antenna to BioDiValue Tracker•Better opportunity provide consistent and timely datasets to BioDiValue Trackers and input to BioDiWare software. Datasets available through BioDiValue Tracker are expected to be as close to real time as can be. Dataset quality expected to be consistent throughout as AIS data feed is subject to standards.•Less prone to human errors related to manually handling updates every time•Depending on AIS implementation it may be possible to capture AIS data from several nearby locations in one BioDiValue Tracker•Pre-processing of dataset allows user to select vessel positions according to defined distance from coastline from BioDiValue Tracker

Limitations•Require more infrastructure when and if more than one AIS antenna feed is to be combined (minimum 1 in Sicily depending on topology and 1 in Malta) in one BioDiValue Tracker. This complication can be avoided by developing a BioDiValue Tracker for every antenna. Combined feeds from multiple AIS Antenna’s that overlap in range require changes to the preprocessing before pushing the data onto the BioDiValue Tracker.•Significant resources need to be allocated for knowledge transfer to happen and support period to ensure a smooth implementation

Important notes when preparing dataset to be imported into BiDiValue Vessel Tracker

1. All data is to be saved as text in csv format 2. Datetime fields to be saved as text in the form of yyyy-mm-dd hh:mm:ss 3. When Required fields are not included, records are discarded and not included in the final dataset for mapping
