Data Policy and Information Management Planning Linda Harwell US EPA/ORD/NHEERL/GED
“The overall purpose of these policy statements is to facilitate full and open access and use with confidence, both now and in the future, of the data and information . . .” (Hale, et. al., June, 1999)
Objectives Piecing Together Your Plan
Key Points • What are the policy/plan objectives? • How will the data policy support program objectives? • What “type” of data will be contributed? • Who is the most likely audience? • What are the partnership roles and responsibilities?
EMAP IM Plan Objectives • Providing a data directory so that data of interest can be identified • Providing access to data and metadata files • Assisting with database development and/or administration • Providing support to EMAP working groups for planning, research, monitoring, and analysis efforts so that differences in information management environments of the groups are minimized • Ensuring a distributed data structure, allowing responsibility for the data to reside with the owners • Maximizing interoperability with other environmental monitoring data systems in accordance with CENR objectives
Supporting Program Objectives . . . . . . Is vital to the “health” of your IM program
Data Expectations • Data sets • Documentation of data sets • Statistical methods • Methodology for evaluating data • Reports • Spatial data • Other derived products • Data ownership/stewardship
Target Audience • Identify the primary user • Use “simple” language • Plan for training (i.e. workshops) • Provide guidance • Understand the user’s IM culture
Role and Responsibilities • Outline • What needs to be done • Who will do it • Provide reasonable expectations for all partners Clear definitions help minimize misunderstandings and delays
We’re supposed to enter the field data!? What Role Are You Willing to Play? Just a little inconsistency here * Two separate data fields
Objectives Technical Specifications Piecing Together Your Plan
Key Points • How should the data flow? • What hardware/software should be used? • What tools should be made available to partners? • What are resource needs?
Other Considerations • Software limitations • Email attachments • Available software • Internet protocols and firewalls • Network Contraints • T1 vs. frational • Computers and operating systems • Current and future expertise needs

Objectives Technical Specifications Implementation Piecing Together Your Plan
Recommendations and Guidelines • Quality assurance/control • Preparation and delivery of data • Data distribution for public use Providing “tools” help ensure you get what you need -- when you need it
