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

• 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

Metadata

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

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
