    4. Geographic & Historic Context What is the Issue?

    5. State & Regional Implications Act 138 – Agricultural Easement Purchase Program How Many Counties are Involved? Statewide Facts and Figures Over $581,000,000 Spent Over 275,000 Acres What Other States?

    6. Berks County Farmland Preservation History of Preservation in Berks County History of ALP Office How Does GIS Play a Role? Why a Change Now?

    7. Land Evaluation Site Assessment (LESA) What is it? Who Uses it? Why is it Used? When Was it Built? Who Built it? What Platform Built on?

    8. Project Objectives Create New LESA Application for the Berks County Agricultural Land Preservation Office (ALP) ESRI ArcGIS 9.3 Technology Same Data and Scoring Procedures Used Intuitive and Adaptable Interface More Efficient Outputs for Analysis and Ranking Input from ALP Staff Proper Documentation and Training QAQC Background Objectives Methods Data QAQC Timeline Results/Benefits Challenges

    9. Project Requirements Resolve GIS Data Needs and Program Criteria. Needs Assessment Client Involvement Tackle Software and Code Problems of Legacy Application ESRI ModelBuilder for Software Development Application Documentation Client Satisfaction

    10. Assessment Criteria What are Program Criteria? Land Evaluation vs. Site Assessment Why is GIS Important? How Complex? Background Objectives Methods Data QAQC Timeline Results/Benefits Challenges

    11. Software Development – Model Builder What is it? Ties Together Tools, Data and Analysis Modules Geoprocessing in Manageable Parts Automate Python Scripting

    12. LESA – Data Requirements How Many Data Sets? From Where? Unique Information

    13. LESA – Data Requirements Tax Parcels and Preserved Farms Current Applicants Ag Security Areas Roads and Highways County and Municipal Boundaries Sewer and Water Service Areas Soils and Land Use Cluster Areas Historic, Scenic, and Government Lands
