Currently a full-time GIS analyst, helping clients meet their business objectives. Looking for that hidden gem or hard to find area? Maybe you have a scientific application or business problem that needs a verifiable solution. Why not retain a highly skilled certified GIS Professional (GISP) and published author with 27 years of experience to get the job done right? Knowledgeable, time-efficient and adept - with 100% client solutions solved wielding GIS technology. Excellent depth of analytical skills fine-tuned by almost three decades of listening to real-world problems and then translating them into solvable GIS problems. Published GIS author; B.S. Environmental Studies; Linux certified. Special interest connecting with data center clients, finding sites co-located with suitable terrain, fiber proximity, cooling water power and population density. Work in the green sector includes solar development (site selection and suitability), identifying buildable land and constraints; finding suitable locations on commercial building rooftops for solar using LiDAR; identifying customer locations and their proximity to electric vehicle (EV) charging stations (alternative fuels). Have worked on many projects needing lead generation. Use of GIS software and county appraiser parcel data identifies both the suitable properties as well as owner contact information. Applied applications of GIS technology to areas such as infrastructure, telecommunications, renewable energy, risk assessment, water resources, road & rail networks, land development and mining. First in the state of Florida to receive agency approval for GIS-based stream bank modeling (other surface waters). Other modeling methods have saved clients enormous amounts of time and money, such as modeling hydrologic features on l in the example of predicting where stream locations are in a 20,000 acre site. Modeled hydrologic features and flood potential in utility corridors. Mapped and managed field data for two 20,000 acre projects and a 10,000 acre project (GPS and GIS data). Expert using GIS desktop software and also developed expertise providing GIS services via web mapping and web services (WMS/WFS). Use open source software on Linux to share GIS data on the web via Leaflet. Available for tutoring or teaching opportunities.
