Community Demonstration Project Issues for BPD • Thankful to be a CDP site • Community Demonstration Project Issues for BPD • Thankful to be a CDP site • Metadata is “twice removed” from local law enforcement agencies (LEAs) – Good reason to include an LEA as a site – Poses new communication challenges • Resources – Crime Analysis Unit is at half-staff – Lack of funds, other resources – Lack of previous knowledge about metadata

RCAGIS Status RCAGIS • April 3 - Delivered RCAGIS 1. 0 (we had several RCAGIS Status RCAGIS • April 3 - Delivered RCAGIS 1. 0 (we had several alpha and beta versions) – Automated and interactive crime analysis – Automated and interactive mapping – Automated reports • June 5 - Began training Baltimore County Police Department (Baltimore City and Howard County to immediately follow) – Officers – Crime Analysts – Police managers and command staff

RCAGIS Status Data Sharing and Metadata • Two BPD personnel received metadata training • RCAGIS Status Data Sharing and Metadata • Two BPD personnel received metadata training • Identified geographic data to share via clearinghouse nodes • Identified a potential clearinghouse node – (University of Maryland, Baltimore County) • Improved relationship with Baltimore City GIS Staff

Next Steps • Find the appropriate NSDI node to serve as a host • Next Steps • Find the appropriate NSDI node to serve as a host • Encourage other RCAGIS police departments to use FGDC metadata standards • Document and share the success of CDP and RCAGIS
