MIDA Vision
MIDA should become a key on-line MIDA should become a key on-line resource for all who are interested resource for all who are interested in coastal and marine information in coastal and marine information
and data for Irelandand data for Ireland

Data Collection Approach
• Identify Priority layers
• Identify Data Holders
• Determine spatial data exists
• Acquire/create data layer
Coastal Atlases Workshop July 25 th , 2006Ned Dwyer, CMRC
Data Agreements
Data Supplier Conditions• Display in the atlas• Copyright• Download • Etc.
Memorandum of Understanding
CMRC Conditions• No third party use• Restrict access to attributes• Costs of licensing, purchase• Etc.
Coastal Atlases Workshop July 25 th , 2006Ned Dwyer, CMRC
Data Quality
• Variability in quality– Data presented as owner provides it– Atlas presentation issues
• Metadata– Difficulty acquiring adequate metadata– Data compromised if MD insufficient
Coastal Atlases Workshop July 25 th , 2006Ned Dwyer, CMRC
Time Consuming because:
• Data in many organisations• Lack of data catalogues• Providing data seen as
low priority• Limited GIS ready data• Variable data quality• Poor/non-existent metadata
Data Collection Challenges
Coastal Atlases Workshop July 25 th , 2006Ned Dwyer, CMRC
• Robust data model• Huge time investment• Poor data documentation• Intellectual property
rights• Expensive base data

Technology: Database DrivenTechnology: Database Driven
• Optimises data management• Permits efficient searching• Facilitates catalogue sharing
• Data files are not in a database

Technology lessonsTechnology lessons
• Open source allows flexibility• Requires programming capability• DB management system vital
Coastal Atlases Workshop July 25 th , 2006Ned Dwyer, CMRC
• MIDA review of existing standards– Dominant standards– Review of each standard– Metadata sharing considerations– Future trends in standardisation
Metadata ReviewMetadata Review
Coastal Atlases Workshop July 25 th , 2006Ned Dwyer, CMRC
• Among reviewed:– FGDC (USA)– ANZLIC (Australia)– NGDF (UK)– ISO 19115 – CEN (Europe)
Metadata StandardsMetadata Standards
Coastal Atlases Workshop July 25 th , 2006Ned Dwyer, CMRC
• Currently no national standard• Organisations choose own standard
– If metadata exists!– Marine Institute, EPA, GSI ISO 19115
• ISDI in development– For governmental organisations– Led by Dept. of the Environment– Meet ISO 19115 standards
Metadata: Irish Situation
Coastal Atlases Workshop July 25 th , 2006Ned Dwyer, CMRC
Metadata in MIDA
• Discovery– Core database– Subset / Profile of
ISO 19115– 55 elements– ISO XML tags
• Abstract– Initial metadata access– Taken from Discovery DB
• Full– As data owner supplies it
Coastal Atlases Workshop July 25 th , 2006Ned Dwyer, CMRC
Discovery Metadata Entry
• Custom-built wizard• Web-accessible• Basic error checking• XML output
Coastal Atlases Workshop July 25 th , 2006Ned Dwyer, CMRC
Metadata for Data Management
• MIDA data management
• ArcCatalog FGDC• Saved with archived
data
Coastal Atlases Workshop July 25 th , 2006Ned Dwyer, CMRC
Metadata Lessons
• Poor metadata availability• Creation time consuming• Appreciated by users• ISO 19115 has facilitated catalogue sharing

Current Atlas Development
• Node in Irish Spatial Data Exchange (ISDE) – Shares metadata across distributed network
• Maintenance and update of data & info. – New layers & information pages
Coastal Atlases Workshop July 25 th , 2006Ned Dwyer, CMRC
What’s Next with MIDA?
• Improve efficiency of data management
• Design & presentation• Regional datasets• Additional tools• Educational modules
Will collectively address issues this week
Coastal Atlases Workshop July 25 th , 2006Ned Dwyer, CMRC
• MIDA is a key part of marine infrastructure in Ireland• MIDA is a successful cross-border collaborative effort• MIDA is the only Irish web GIS to bring together
spatial data from so many organisations• MIDA is a flagship project of the CMRC and will be
maintained into the future
