Bond Forfeiture Program (BFP)
The Bond Forfeiture Program (BFP) at the West Virginia Department of Environmental Protection (WVDEP) is tasked with both land and water reclamation on mining sites where the performance bond has been revoked.
• Reasons for Revocation– Failure to meet mining/reclamation standards– Failure to meet final discharge limitations– Bankruptcy
• Funded through– Revenues from per ton tax on each ton of coal mined – Forfeited reclamation bonds – Civil penalty collections

The Bond Forfeiture Program (BFP) at the West Virginia Department of Environmental Protection (WVDEP) is tasked with both land and water reclamation on mining sites where the performance bond has been revoked.
• Water quality monitoring is a key component– Planning – Design – Implementation– Long Term Maintenance

•Data Integrity• Legacy Location Information
Suspicious Coordinate Locations
June 11, 2008West Virginia GIS Conference 2008
• User Interface / Functional Requirements– Verify and Improve Coordinate Locations for
Existing Water Sample Sites• Easy to use• Allow both GPS and Map based edits• Optionally verify and update related in formation• Allow field collectors to identify and map new
sampling sites• Update required fields in the enterprise database
Mobile GIS solution

Mobile GIS solution
• Data Integrity– Legacy Location Information– Lat Lon / DMS, no datum, little documention or
even corporate memory of original collection methods,
• Workflow / Intended users– Target platforms
• Handheld Pocket PCs • Tablet PCs• Field Laptops
• Application/Code Maintenance and Deploy
June 11, 2008West Virginia GIS Conference 2008
Solution
• ArcPad 7.1– New AXF File Format Supports Related
Tables and Facilitates Smarter Geodatabase edits (sde)• Layer customizations (styles, layers, forms,
and code), relationship rules, and multiple representations are all stored within a single AXF
• Shapefiles still supported (Read Only)• Code Deployment ~Zero Overhead
June 11, 2008West Virginia GIS Conference 2008
• ArcPad 7.1– Query Builder and Custom Query Forms
• Enhanced Find Dialog allows for simplified forms as well as complex queries
Solution
June 11, 2008West Virginia GIS Conference 2008
• ArcPad Data Manager ToolBox– Get Data for ArcPAD (Check Out Only)– Get Data from ArcPAD
June 11, 2008West Virginia GIS Conference 2008
• Workflow– Monthly Site Visits
• Site Selection / Existing Samples
– Field Assessment– Sample Collection
• Location Verification– GPS or Map Sketch– Attribute Check
• Sample Analysis
– Sample Verification– Data Commits
June 11, 2008West Virginia GIS Conference 2008
• ArcPad Data Manager Extension– Easier to Manage Mobile GIS Projects– Get Data for ArcPAD (Check Out vs Copy
Out)• Security enhanced – supports both
encryption and password protection

Goals for Future Development of Enterprise Mobile Applications at WVDEP
– simplicity of use – reduce the cost of implementation
• development and maintenance
– improve overall integrity of key environmental data
June 11, 2008West Virginia GIS Conference 2008
Current and Future Work
• Provide in-field access to more extensive land and water related data– Field assessment, mitigation
• Integrate additional sensors– Field probes, range finders
• Mobile Services – Leverage ArcGIS Server 9.3 Mobile Application Manager to
rapidly build and deploy simple map viewing and editing tools
