  • Currently preparing fault maps and supplying GIS support for Earthquake Engineering Research Institute's Earthquake Scenario for San Diego - Tijuana region. Assessed available fault datasets to choose best/most relevant data. Worked with City of San Diego and FEMA to migrate data to a larger server. Minor use of QGIS.
  • GIS Analyst - 6+ years experience: tasks including pre-process / clean data, reproject datasets, convert Excel files to shapefiles, digitize input, create map document, generate and edit topology, join tables, clip vector and raster files, query data, create multiple data frames, add legends, label features, change labels to annotation, import and georeference CAD files and graphics, export data in various formats, buffer and dissolve features, build and process raster files with Spatial Analyst and map algebra, and wrote metadata.
  • Built 3D geologic framework model: Combined and processed surface and subsurface geology data from San Diego / Tijuana area. Assembled and analyzed 7 geologic datasets from San Diego / northern Baja California and merged them to create a cross-border geologic map used as the top surface for a 3D model for a regional groundwater resources study. Interpreted depth points from oil exploration wells, test holes, USGS multiple-completion wells, production water wells, wells drilled for monitoring and irrigation, and offshore seismic reflection profiles to provide depth data for the model using ArcGIS and EarthVision. This model has been used by cooperators and consultants to predict stratigraphy during drilling.
  • Currently mapping faults and supplying GIS support for Earthquake Engineering Research Institute's Earthquake Scenario for San Diego - Tijuana region.
  • Wrote Python scripts to correct ArcMap document links after server upgrade/translation.
  • Created file geodatabase - Pajaro project, composed of landuses (mainly crops) vs. water resources (groundwater regions, water distribution, and administration). The geodatabase contained feature datasets, feature classes including a topology, subtypes, domains, and non-spatial tables. Goal: provide sufficient information for water authorities to revise their pricing structure.
  • Modified and ran climate model grids: used Python scripts, documented procedures.
  • Designed Scripps Ranch wildfire risk project: based on SanGIS veg95, major roads, and 2003 burned area from SanGIS and satellite imagery of Scripps Ranch from Google maps, all clipped to zip code 92131. I added an additional field "flam" to the veg layer for flammability, assigned a "flam" value of "0" to water areas, "1" to low risk vegetation (developed areas, irrigated agriculture, etc.), "2" for moderately flammable (grasslands), and "3" for highly flammable areas (eucalyptus forest, chapparal) and symbolized the map to show flammability. This was the basis for a larger scale project for the Red Cross.
  • Work with ESRI, USGS, TIGER, SanDAG, SanGIS, and Google map data files. Use ArcMap, ArcCatalog, ArcScene, ArcINFO, RockWorks, and prepare files for EarthVision.
  • Create and run batch and model processes with Modelbuilder and Python.
  • Customer service oriented, adaptable, trouble-shooter / problem solver.
  • Transitioned and upgraded Red Cross Disaster Operations Center web pages from iGoogle to Google Sites, proactively added new functionality to web/GIS interface, and built wildfire hazard layer for San Diego County using for the vegetation database to display in the Common Operating Picture.

REFERENCE URLs San Diego Association of Geologists is totally my production. I built the site in 1997 and have expanded and maintained it ever since. The idea is easy, intuitive navigation, with content maintained at least once a month. To help with meeting logistics, I developed some cgi/perl scripts to collect registrations and food preferences, print out the reservations for the officers via password protected pages, allow the officers to edit the reservation list, then rename the file after the meeting to start a new list for the next meeting. Users/members of the organization really like the site. Mojave Water Resources website. I made a point shapefile from groundwater level data, drew contours, digitized contours to export as an image for the interactive web site. Wrote or updated much of the HTML, PERL, and JavaScript code for the Google map page, wrote metadata, exported GIS data to web format. As part of a DOD Mentor / Protégé program at ARINC, I restructured the Integrated Consultants Inc. website for improved stability / usability and taught the client how to maintain his website with Dreamweaver. Mike Hart wanted a small site to describe his areas of expertise to potential clients - including government agencies, attorneys, land developers, homeowners, and geotechnical consulting companies. San Diego Environmental Professionals wanted a website to communicate with their members and with the community in general. I wrote several cgi/perl scripts so officers can update meeting information, collect reservations from the website, and print out a sorted list of reservations for check-in at the meeting, This was a turn-key project which they now maintain. This is my personal website that shows a number of projects I have worked on including various multimedia assets. There is also a small demo directory which is more "corporate" style (with Flash roll-over buttons) and includes a searchable cgi/perl/flatfile product database I built at: http://www.caro-lion/Demo/home.html.
