Locational Data Improvement Strategy An Evolving “Work in Progress”
Locational Data ImprovementStrategic Themes • Locational Data Policies & Standards- Latitude/Longitude Data Standard update- Locational Data Policy update- Agency-wide ICR • Tool Development & Evolution- Maintenance Update of LRT • FRS Locational Data Improvement- FRS Sits Locator Tool • Streamlining Data Exchange- Integration of “place” in CDX
Collection Methods - Simplify list Accuracy Measures- A Tiered Approach Reference Datums Reference Points- Expand list Update in Context of:- LRT interface - Polygonal data- Data integration- Emerging Standards Latitude/Longitude Data Standard Update
Lat/Long Standard UpdateCore Recommendations 1. Alignment with LDP Accuracy Goal (25m). Recommendations: • Establish a “preferred tier” approach of methods used to collect coordinates • Retire those collection methods that are centroids of Census Blks. & Zip Codes
Lat/Long Standard UpdateCore Recommendations • Simplify options for Collection Method documentation in field. Recommendation a) Condense the permissible values to two lists through pull-down menus
Lat/Long Standard UpdateCore Recommendations • Address variability of recorded Accuracy Measure values. Recommendations • Retire the Accuracy Measure data element from Mandatory to optional. • Conduct a statistical analysis of accuracy values based on collection methods • Post derived Accuracy Measure values on the EDR.
Lat/Long Standard UpdateCore Recommendations • Expand the list of permissible values for “Reference Point,” harmonize w/LRT a) Two options: Maintain two lists through pull-down menus or retire the “generalized” list found in the L/LDS.
Lat/Long Standard UpdateCore Recommendations 5. Address need for establishing a new standard for documenting polygons. • Conduct a needs assessment of Agency program systems, Regions & States • Develop a profile data standard for use in the Agency and State partners • Develop a set of data elements for areas
