Methods
Four-stage process:1) Divide image into
segments of like pixels
2) Create rules to group segments into classes
3) Manually correct misclassified segments

Conservation Toolbox
• Web-based application- Non-GIS users
• Parcel identification and assessment- Conservation and restoration criteria
• Product generation- Summary reports- Spreadsheets

County Partners
Prince George’s Stormwater BMP Prioritization Tool
- PG County sought to retrofit 20% of urban impervious through their MS4 as outlined in their WIP
- How does this tool solve this problem? - HUC size- Land type- Zoning- Stream data
• Benefits- Web-based application- Non-GIS users- BMP site identification through dynamic queries- Product generation (ie. Spreadsheets)
Stormwater BMP Prioritization Tool
Stormwater BMP Prioritization Tool
• Problem? - Planning commission needed a better way to prioritize BMP proposals- BayFAST needs land cover data
• Goal? - Streamline and track conservation efforts more accurately and effectively
• Result?- Uniform process of estimations and proposal submission- Saves money and time by cutting out need for consultant
York County Stormwater Consortium BMP Reporting Tool
York County Stormwater Consortium BMP Reporting Tool
65 Acres Treated95% agricultural, 2% Barren, 2% Low Vegetation, 1% Tree
CanopyEstimated Load Reductions: 20 lbs N, 8 lbs P, and 1500 lbs
sediment Estimated Cost: $150,000
Calculating the Potential Benefitsof Individual Projects
City Partners
Vacant Lot Opportunities Analyst
• Problem?- Estimated that there are 17,000 vacant lots in
Baltimore; how do you prioritize for green space suitability
• Goal?- “Transform vacant lots from liabilities to assets
that provide social and environmental benefits”- 40% tree canopy cover by 2037, currently around
~28%• Results?
- Green Pattern Book, outlines development options and site suitability criteria
Benefits of Vacant Lot Opportunities Analyst
• Vacant lot prioritization– Proximity to amenities– Acreage– Land cover type
• Desktop-based application– Basic ArcGIS knowledge
Vacant Lot Opportunities Analyst
Urban agriculture Less than 7.5% slope Less than 25% tree
cover Greater than 0.5 acres
Neighborhood park Less than 5% slope Less than 50% tree cover Greater than 0.125 acres
Vacant Lot Opportunities Analyst
• Generates “short list” of suitable candidates
Funding and Support• Lincoln Institute of Land Policy • ESRI• Microsoft Research• Hexagon Imagery Company
Pilot Project • Southeast Utah• Nanticoke River, DE and MD
Future Applications: Cloud-Based Land Cover Factory
