1. Virtual Ice Charting System Archive Browser Interface Distribution IngestProduction Ice Analyst Application Database Click on the boxes for more information

2. 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 –Pull: user access to a website Ensure invalid information is not available (e.g. out of date) User can preview or thumbnail, download, print Anonymous ftp for large files Metadata available –Push: centre actively sends data to users ftp, fax, e-mail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 nomenclature Chart production Egg tools Chart layout Projection

9. 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 don’t 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
