Fast Forward The Future

This world keeps turningAnd we're safe and soundBut there's more to lifeMore to expoundThis world keeps learningWith a knowledge we're unboundNo more debateThat the earth is round ”

CARIS’ Software Vision

Inputs and outputs in a data centric workflow

Organizations are considering data centric workflows

• To realize efficiencies– Quicker turn around of bigger survey datasets– Increased automation in processing and product compilation– Better utilization of human resources– Change in the focus of human resources “Data Analysts”

• To support a broader user base– New and ad hoc products and services– Big Data possibilities

• To transition from producer to marine data provider– In line with Open Government and Open Data policies

– Support principal of “collect once, use many times

Why data centric?

4

• Open data storage• Connectivity to 3rd party tools• Extensive scripting capabilities• Cloud based processing potential• Mobile data entry and access

Service orientated and standards based systems

• Rules-based workflows• Survey processing and cartography• Faster and better quality results• Validation of data in field prior to loading into database

5

• Basic technical challenge of interoperability has been solved– Standards based technology and data

• Organizations need an interoperable approach– To maximize value from marine spatial

data,

– Through Open Geospatial Consortium (OGC) and International Hydrographic Organization (IHO) cooperation

Interoperability

Marine spatial data

Data plugins

(GDAL and PDAL)

APIs (Python)

Standards (OGC)

• IHO and International Association of Oil and Gas Producers (IOGP)– Members/contractors both collect data and produce products– Data used for different purposes, but much of the data is the same

Harmonization

Product centric approach Data centric approach

6

• Seabed Survey Data Model developed by the Oil and Gas industry to standardize survey deliverables

– GML application schema

– It is based on an ESRI data model

– Now also supported in CARIS solutions

– Allow hydrographic agencies and oil and gas companies to exchange data more easily

Crowd-Sourcing

Autonomous surveys

Process automation

• Increased number of platforms / sources = increased data volume to be processed

– Autonomous and multi-sensor platforms

– Opportunistic multibeam surveys

– Crowd-Sourced Bathymetry

– Satellite Derived Bathymetry

• Can marine agencies cope with the influx of data?– Need to reduce, not increase, the processing backlog

– Driving the need for automation, and near real-time processing

Process automation

• By automating data processing the platforms users can:

– Obtain repeatable results and real-time QC

– Optimize use of human resources (i.e. allow staff to focus on other survey and GIS tasks)

– Reduce data collection to product time, and processing backlogs

• All of this will enable agencies to provide marine data to broader customer base

12

• Availability of autonomous survey platforms has increased dramatically over the past few and market will continue to grow

– Both AUVs and USVs

• Potential benefits are clear: lower capital and operating costs, rapid deployment/recovery, ability to work closer to the intended target, force multiplier

Autonomous surveys

• Currently, the platform is sent on a pre-defined mission to gather data, which is stored internally until recovery and then processed

• As power sources extend operating times, little has been done to address the data bottleneck

• Autonomous platforms often lack the ‘human control’ in the feedback loop

• Make processed results available to the surveyor during operations

• Data deliverables may be slower

– Data typically has to be processed after download at end of mission (small real-time communications bandwidth)

– Data could be incorrectly acquired due to lack of surveyor interaction with platform (no feedback loop)

• Near real-time processing and QC needed

SURFACE MESH

Motivation – Current solution

• Divide model into depth range and resolution– Have to manage multiple models– Discontinuity near boundaries

• Use a TIN– Limited in size– Holidays– Edge removal

21

• Allows multiple resolution areas to be defined and data of varying density to be modelled in single surface

– Density estimation tools determine most suitable resolution(s) based on input data

• Better representation of real-life situation– Better analysis

• Provides a single model for creation of contour and other bathy products

– Use in charting and other GIS products

• Additional uses:– Base layer for hydrography theme in Marine SDI (MSDI)

– Input to form Common Operating Pictures (COP)
