Great Baltimore Fire of 1904 - fire companies from as far as Atlantic city responded only to be found useless since they had different hose coupling sizes that did not fit Baltimore hydrants - fire burned over 30 hours, resulted in destruction of 1526 building covering 17 city blocks.

Coordination InitiativesCoordination Initiatives
• 1994 - Executive order 12906 calls for establishment of the National Spatial Data Clearinghouse (NSDC)
“… to avoid wasteful duplication of effort and promote effective and economical management of resources by Federal, State, local, and tribal governments…”
• Federal Geographic Data Committee (FGDC) began NSDI
• PASDA began in 1995 as NSDI node.

Importance of GIS Importance of GIS StandardsStandards
• Enables seamless regional integration for planning, emergency management and other uses
• Reduce the redundancy and duplication of data production
• Promotes a common set of terminology to enable organizations to describe, utilize, and share information and data
• Enables technology independent solutions
• Provides a basis for conformity assessment
![Page 20: The Role of Data Standards in GIS Coordination PAGIC/PAMAGIC Standards Town Meeting.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649e835503460f94b852aa/html5/thumbnails/20.jpg)
GIS StandardsGIS Standards
• Metadata—FGDC Compatible• Data Creation—Setting the
parameters for how data is collected, defined, encoded, and organized
• Data Development & Management—Projections, Scales, Datums
![Page 21: The Role of Data Standards in GIS Coordination PAGIC/PAMAGIC Standards Town Meeting.](https://reader035.fdocuments.us/reader035/viewer/2022062422/56649e835503460f94b852aa/html5/thumbnails/21.jpg)
Data CreationData Creation
• Standards for accuracy & quality
• Standards for addressing• Standards for attribute
encoding—naming conventions, common code set
• Definitions of feature types—what defines a road, what defines a stream, etc.

Development & Development & ManagementManagement
• Compatible transfer format• Continuity of projection, scale,
resolution, datum, etc.
