2. Significant Activities Cooperative Road Centerline Detailed Digital Elevation Models using LIDAR Large-scale digital orthophoto production Partnership Building

3. Highway Information Services Division The Maryland Statewide Cooperative Road Centerline The Maryland Statewide Cooperative Road Centerline

4. Working Together to Integrate the State one County at a time. A Sustainable Partnership for Success

5. Who SHA Highway Information Services Division Statutory Mandate for Public Road Data Collection Public Road Inventory Database Highway Mapping/Cartography GIS-based and attributed public highway system centerline, numerous map products and applications SHA has centerline currently good for planning, and 1:24K maps

6. Use of same centerline where possible Use of linked/related centerline through unique ID’s will support different geometries Help keep data up to date through digital spatial data updates on both sides Each party does what they do best What is the SHA Shared Centerline Program?

7. SHA has current centerline of major roads SHA is working towards 1:2400 scale centerline data of every public roadway Adding ramps, spurs, aux roads, rab’s SHA also looking for improved road names as well as addresses Willingness to share maintenance and data in future What Are the Qualities of the Data Under Development?

8. Benefits to State and Local Government MEMA Homeland Security EOC Emergency Management County Planning and Public Works County and Municipal 911 Call Centers Fulfills Phase II accuracy requirement Mutual Aid Mapping State Health Concerns (ex. SARS, WestNile Virus, Flu) Voter Registration Database (Board of Elections)

9. Leveraging Existing Projects HISD Investment in Statewide Road Data Existing Annual Highway Inventory Processes Highly Accurate County Data

14. Status 17 of 23 counties participating at some level Data from 11 counties received by SHA 2 counties completed: Howard & Montgomery

40. LIDAR 2004 DNR – St. Mary’s & part of Charles Charles – completed their county Anne Arundel – paid for their county Howard – paid for their county All through 1 contract vehicle Same spec, same process Significant price break

41. C2K Accomplishments 4.1.3.3 Protect 20% of Watershed 4.1.5 Develop and maintain in each jurisdiction a strong GIS system

42. 4.1.3.3 - 20% Protection 19.89% of Maryland protected DNR, MDP share responsibility of mapping protected lands But... acres protected NOT all GIS acreages

43. Landscape Analysis used in Targeting Acquisitions Potential properties screened against Green Infrastructure Maps created to support acquisition request (BPW)

44. 4.1.5 – Strong GIS Maryland’s Implementation Team (I-Team) Plan MDP continues Smart Growth Data Partnership DNR provides free access to its GIS data via Internet (www.dnr.maryland.gov\gis) DNR and MDP are working with local governments to improve the Protected Lands database DNR works closely with counties sponsoring Rural Legacy applications MDP conducted its “Development Capacity Study” to inventory lands within Priority Funding Areas DNR conducted a Cooperative Geospatial Data Survey with local governments Maryland Metadata Resource Guide – www.marylandGIS.net
