“Community Benefits of Earth Science”DEVELOP Internship Program Student-led / student-run programwhich produces earthscience-based pilot projectswith supervision fromNASA scientists DEVELOP students combine fieldworkwith NASA facilities, techniques,computers, and technology Projects directed towardscommunity development, management, localpolicy and/or environmentalissues in support ofdecision-support tools
“Community Benefits of Earth Science”Waste TiresPrevious techniques: California Highway Patrolhelicopter surveillance Communication with locals File and records checks Follow-up on location tipsWaste tire piles pose potential environmental threats inthe forms of toxic fires and as mosquito habitat.
“Community Benefits of Earth Science”Project Goal and TechniquesGOAL:Use commercially available high-resolution satelliteimagery to locate and map illegal waste tire pilesin two climate regions of California.TECHNIQUES / TOOLS:standard image analysis methods, pertinent geospatialtechnology, computer automationDESIGN OBJECTIVE:Create a methodology with end-user functionalitythat rapidly and consistently analyzes satellite imagery.

False-positives were commonly attributed to shadows, water, debris pilesand features with tire material content such as black tarps,polyethylene tubing, and parking lots. Continued communication withfield inspectors will dramatically reduce number of false positives.
“Community Benefits of Earth Science”Benefits of Technology Technology reduces time required to by CHP and others toinitially survey a region for tire sites and increasesinspectors / managers time for mediation of sites Provides a synoptic, geographically accurate survey of an area Geographic Information Systems (GIS), used to create hard-copy maps, can be customized to inspector’s and manager’sgeospatial and visual preferences Satellite imagery is a readily commercially available product Unique technology may be further developed for use inlocating and mapping environmental nuisances such as oilspills, landfills or other waste-related issues
“Community Benefits of Earth Science”Conclusions Effective communication between analysts and inspectors isessential to successful results The model accurately located all waste tire piles used fortesting and located at least two new sites Project was completed on-time and within budget
