Ingest

• Data from different sources are ingested and
  made ready for further production, including
  formatting.
• Isolate unique formats of external data from a
  common geospatial internal format
• Modular to allow new data types to be added
• Metadata preserved along with data
• Supports multiple projections
• Support for multi-spectral imagery

3
Production

• Production includes rectification, compositing
  (spectral, spatial and time), value adding, e.g.
  production of SST fields and SAR filtering.
• Ability to apply custom algorithms
• Rectification
• Compositing
• Value addition
• Data extraction (e.g. to GRIB)
• Classification routines

4
Database

• The database is an online representation of data
  and products relevant for the ice analyst, e.g.
  images, old ice charts, wind fields etc. There
  may be one or several databases.
• All data co-registered geospatially
• Robust, reliable
• Fast access for real-time production
• Catalogue and search tools
• Administrative tools

5
Archive

• Holds the data and product catalogue both
  on-line and off-line
• Secure data cannot be lost or purged
  accidentally
• On-line catalogue of all archive holdings
  (including non-digital)
• Mechanism to stage between on-line and off-line
  locations
• Multiple formats ability to update formats
• Extract copies to re-populate database

6
Distribution

• Methods for distribution of data and products to
  end users.
• Pull user access to a website
• Ensure invalid information is not available (e.g.
  out of date)
• User can preview or thumbnail, download, print
• Anonymous ftp for large files
• Metadata available
• Push centre actively sends data to users
• ftp, fax, e-mail
• Administration
• Collect user information
• Survey clients
• Users can create custom profiles
• Secure access to proprietary or sensitive data

7
Browser Interface

• An application enabling the user to browse the
  (metadata) database.
• View all types of data in the database
• Search or select data by region, type of data,
  date (range), source
• Ability to thumbnail or preview
• Automatic update

8
Ice Analyst Application

• Consists of two main modules

Ice analysis production Image display Vector
overlay Vector editing Attribute entering Quality
control Input of metadata
Ice Chart Production Conversion to WMO

General Requirements

• COTS with a mature life cycle.
• Supported by maintainance.
• An organization interested in improving the
  software
• An organization interested in working with the
  client
• NOT TURN KEY. Time and materials contracts or
  rapid prototyping are better.
• Runs on Windows AND Linux.
• As little IT support needed as possible.
• Common file formats Ex. Shape files.
• As modular as possible.
• Customizable in-house by non-IT specialists

10
General Requirements (cont)

• Supports legacy files.
• ARCGIS systems should support reformatting to
  coverages
• Comprehensive documentation On-line context
  sensitive help
• Training using your imagery and products if
  possible
• Users dont need to interact with the OS
• Support for multiple monitors
• Support standards for spatial data accuracy
• Supports the capture and entering of national,
  international and other standards
• GO BACK or UNDO BUTTON everywhere
• One-button printing of current views or screen
