SIPAS System History

• Paper Transitioned to Paper Replicated
• GRASS, NSIPS, Terascan
• Public Systems except Terascan from Navy METOC
• Transition to ESRI Software
• CARTERRA
• COTS but not so COTS ESRI and Remote View
• Too much custom coding Vendor, not applications
  developer of imagery analysis or GIS software
• SIPAS
• Remote View, ESRI and ESRI Developed Scripts
• COTS with interface developed by ESRI contractor
• Ongoing investment is to maintain ESRI custom
  scripts
• RISK Un-funded or ESRI Will Not Support Us 
• Mitigating Factor There Are Lots of ESRI
  Programmers and the System Is Almost Entirely
  Standard ESRI Applications

SIPAS System Overview

• Hardware
• Mixture of Solaris UNIX, Linux and Windows
  Servers
• Remote View and ESRI on PCs with dual processors
• Dual Monitors
• Laptop Version
• Workstations - Windows Operating System on PCs
• Custom Ingest Software
• Imagine and Terascan are available
• Sensor Systems Remote View Imagery Analysis
  Application (COTS)
• ESRI GIS Software
• ARCGIS, ARCMAP, SDE, IMS
• DISSEMINATION BY ESRI

SIPAS Phase I Data Ingest
6
Ingest

• Ice Analysts have no time to do custom ingest
• What Software? Little In-house Expertise
• Imagine, Terascan, Both Or Something Else?
• Requirements Modular And Upgradable
• Solution
• Custom Modules By ACT And Custom In-house
• All Modules Planned to be Written By ACT Soon
• Still Retain ERDAS Imagine And Terascan License
• Summary Processing the 57 Gigs Per Day of
  Incoming Data To a Standard Format Used By
  Applications Was the Single Hardest Hurdle and We
  Are Not Over It Yet       

7
Ancillary Data

• Met, Ocean, Ice Model Fields into SIPAS
• Goal Is To Have the Data in the Same Format as
  the Imagery and Spatial Data
• Ongoing Process
• Not Fully Documented
• Point of Contact hannam_at_natice.noaa.gov

8
Satellite-Derived Ice Motion

• PIPS 2.0 and 85Ghz SSM/I
• Scatterometer and radiometer data complement each
  other in estimating ice motion
• Where radiometer has difficulties, scatterometer
  does well and visa versa
• Enables complete coverage motion maps

9
Weather Data into SIMS
Temperature and pressure contours created in
ArcInfo from FNMOC gridded data. Shapefile can
be used as a layer in chart production.
10
Weather Data Process

• Data is received from FNMOC in GRIB, cut into N
  and S
• Hemispheres
• Registered in TeraScan and Sent to ArcInfo with a
  header
• Re-projected to Polar Stereographic
• Contours produced

Automated process is command line driven
11
Sea Ice Thickness Data from the Gerson Ice Model
12
Database and Browsing

• ARCGIS Geodatabase
• MSSQLSERVER
• Spatial Data Engine (SDE) Front End
• ARCIMS To Produce Maps
• RemoteView Has A Browser With Thumbnails
• Draw a Box on a Map and Retrieve Available Data

13
Analysis Module

• Sensor Systems Remote View
• Improved By Vendor For Us
• Improvement Based On Our Requirements
• Still COTS Not A Custom Package
• File Formats Completely Compatible With ESRI GIS
  Applications

14
Remote View - Sensor Systems

• Remote View Pro - Version 2.4
• Easily integrates with ARCView
• Create, import, display and edit vector overlays
  (Shapefiles)
• Supported formatsGeoTIFF, JPEG, ERDAS img,
  MrSID, RSAT, ESRI Shapefiles, DTED, etc.

15
SIPAS Phase II Analysis
The Analysis System contains 3 Parts 1- Query of
Available images based on AOI selection 2-
Image Analysis 3- Attributing Create 2 shape
files 1- Ice lines 2- Egg attributes
16
Chart Production

• Currently Use ESRI GIS Package and Old Custom
  Avenue and ARC AML Scripts To Produce .jpegs
• Legacy Method Based On Old Technology
• Moving Towards New Code Based On ARC/GIS VISUAL
  BASIC
• Eventually Automatic Chart Production Using ESRI
  Geodatabase, ARC/MAP, IMS, SDE
• Deploying Zip and Ship of Shapes Based on
  International Color Codes This Year

17
SIPAS Phase III Dissemination
The Dissemination System 1- On Demand 2-
Subscription 3- On-the-Fly Ice chart
18
Archive and On-line Access

• Online Access
• NIC 1995-Current on WWW Site
• NSIDC
• Weekly or Bi-weekly Sea Charts
• JPEG, .e00 Transfer Format,
• International Color Standard
• Every Two Weeks Arctic/Antarctic Hemispheric
  Coverage
• .e00 Transfer, SIGRID 3 Archive Formats
• Deep Archive
• Hemispherics to NCDC in .e00 format

19
Sea Ice Mapping SystemLessons Learned

• No Turnkey Systems
• Rapid Prototyping with user participation
• Custom Software by Applications Vendors
• It is not easy to adopt a new system
• Resistance for changes from users
• Users participate in development/requirements
• Must be obviously more accurate, better, faster
• Find a champion
• Difficulties of the learning curve
• Vendor training using YOUR DATA
• As little customized code as possible in a
  de-facto standard language

20
Sea Ice Mapping SystemLessons Learned

• Overwhelming complexity
• Modular Design
• Documentation
• Transformations, Conversions, Re-formats . . .
• Insist on the same format for imagery analysis
  and spatial data files
• Insist on using standards
• Spatial data, imagery, graphic, archive, colors,
  attributes etc
• Business Resumption and Portability
• Ability to function as a stand alone
• Laptop Version

21
Summary

• COTS
• Modular Design
• Ingest, Analysis, Production, Dissemination
• Same file formats throughout
• User input in development
• Training Using Actual Data
• Availability of programming assets
• Ability to upgrade with legacy support
• Use Standards
• Networked or Stand-alone

Weather Data Process
False color image of SSM/I 85Ghz drift vectors
24
SSM/I Weather Filtering
Sea Surface Temperatures are used to clean
contamination from the ice concentration data.
Further, the land mask is conserved in the ice
concentration data.

Automated Ice Edge

• Final Product Comprised of
• SSMI filtered with QuikScat from PST
• Value-added ice edge from NIC analyst (if
  available)
• Backfill of SSMI ice concentrations

Automated chart (SSM/I J019) compared to the
analyst derived chart for the same day.

National Weather Service Support
Daily weather in the United States is strongly
linked to Arctic sea ice conditions.
