Question 1 - Briefly describe your agency’s greatest issue with
geospatial transportation data
• Public domain restrictions
• Lack of current data
• Lack of feature level metadata
• Duplication of effort
• Lack of data in rural areas
• Maintenance
• Priority of corrections
• Incomplete features and attributes
• Establishing the authoritative source

Question 1 continued
• Adhering to security requirements in a collaborative environment
• Data volume
• Inaccurate address ranges
• Lack of agency specific attributes
• Internal data not centralized
• Need rail, air, and cargo

Question 6 - Provide a brief description or a bulleted list of your Agency’s applications that require
transportation data– Web-based viewer
– Web map service
– Engineering design
– Planning
– Assessment
– Inventory
– Maintenance
– Base maps
– Presentation maps
– Census, surveys
– Evaluating access

Question 7 – Additional Comments
• Utilize existing interagency trails data standard• Consider existing proposals • Align transportation planning efforts with land-
use and ecological reference data• Integrate geospatial data into a "knowledge
network framework”• Consider update access by trusted data
stewards at the state or local level • Analyze the requirement and level of support for
data access in the public domain
11
Answer Commonalitiesfor Questions 1, 4, 5, 6, 7
• Data sources include public and private• Public data sources include federal, tribal,
state, county, and local• Most agencies utilize more than one source
of data• Desire to have public domain data meet
agency needs
12
Answer Differences for Questions 1, 4, 5, 6, 7
• Level of accuracy• Measure of accuracy• Frequency of updates
