Sipas system history

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

SIPAS System Overview

  • Hardware

    • Mixture of Solaris UNIX, Linux and Windows Servers

    • Remote View and ESRI on PC’s 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

ENVISAT

(Under Development)

SIPAS –Phase I Data Ingest


Ingest

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


Ancillary data

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 [email protected]


Satellite derived ice motion

Banks Island

Canada

PIPS

SSM/I

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


Weather data into sims

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.

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

Sea Ice Thickness Data from the Gerson Ice Model


Database and browsing

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


Analysis module

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


Remote view sensor systems

Remote View - Sensor Systems

  • Remote View Pro - Version 2.4

  • Easily integrates with ARCView

  • Create, import, display and edit vector overlays (Shapefiles)

  • Supported formats:GeoTIFF, JPEG, ERDAS img, MrSID, RSAT, ESRI Shapefiles, DTED, etc.

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


Chart production

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

SIPAS Phase III Dissemination

The Dissemination System :

1- On Demand

2- Subscription

3- On-the-Fly Ice chart


Archive and on line access

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


Sea ice mapping system lessons learned

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


Sea ice mapping system lessons learned1

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


Summary

Summary
