                  Data Collection Approach


• Identify Priority layers

• Identify Data Holders

• Determine spatial data exists

• Acquire/create data layer

                       Data Quality


• Variability in quality
    – Data presented as owner provides it
    – Atlas presentation issues
• Metadata
    – Difficulty acquiring adequate metadata
    – Data compromised if MD insufficient




Ned Dwyer, CMRC          Coastal Atlases Workshop   July 25th , 2006
                  Data Collection Challenges

  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

Ned Dwyer, CMRC           Coastal Atlases Workshop   July 25th , 2006
                  Data Collection Lessons


   •   Robust data model
   •   Huge time investment
   •   Poor data documentation
   •   Intellectual property rights
   •   Expensive base data




Ned Dwyer, CMRC          Coastal Atlases Workshop   July 25th , 2006
                  Technology




Ned Dwyer, CMRC   Coastal Atlases Workshop   July 25th , 2006
                  Technology: Software Used


    Open Source Solution

    • Linux Apache Server
    • Minnesota Map Server
    • PostgreS Database

   • Data files are not in a database




Ned Dwyer, CMRC        Coastal Atlases Workshop   July 25th , 2006
                  Technology lessons



• Open source allows flexibility
• Requires programming capability
• DB management system vital




Ned Dwyer, CMRC       Coastal Atlases Workshop   July 25th , 2006
                  Metadata




Ned Dwyer, CMRC   Coastal Atlases Workshop   July 25th , 2006
                     Metadata Review


   • MIDA review of existing standards
        –   Dominant standards
        –   Review of each standard

Ned Dwyer, CMRC          Coastal Atlases Workshop   July 25th , 2006
                  Metadata: Irish Situation

     • 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



Ned Dwyer, CMRC           Coastal Atlases Workshop   July 25th , 2006
                     Metadata in MIDA

     data




Ned Dwyer, CMRC       Coastal Atlases Workshop   July 25th , 2006
                  Metadata Lessons

   •   Poor metadata availability
