    CARTOGRAPHIC COMMUNICATION FOR A SEARCH AND RESCUE MAP A Thesis submitted to the faculty of San Francisco State University In partial fulfillment of the requirements for the Degree Master of Science In Geographic Information Science by Mitchell Wilks San Francisco, California December 2018 Copyright by Mitchell Wilks 2018 CERTIFICATION OF APPROVAL I certify that I have read CARTOGRAPHIC COMMUNICATION FOR A SEARCH AND RESCUE MAP by Mitchell Wilks, and that in my opinion this work meets the criteria for approving a thesis submitted in partial fulfillment of the requirement for the degree Master of Science in Geographic Information Science at San Francisco State University. Jerry Davis, Ph.D. Professor and Department Chair of Geography & Environment Leonhard Blesius, Ph.D. Associate Professor of Geography & Environment CARTOGRAPHIC COMMUNICATION FOR A SEARCH AND RESCUE MAP Mitchell Wilks San Francisco, California 2018 Cartography is a critical element of search and rescue (SAR), with which map makers and map viewers visualize and communicate. This study, in four steps, evaluated the existing 2011 Marin Municipal Water District (MMWD) SAR Map, produced the 2018 MMWD SAR Draft Map, assessed the usability of the Draft Map, and produced the 2018 MMWD SAR Updated Map. In the evaluate-produce-assess-produce steps, the needs and biases of respondents were articulated in the evaluate-assess steps and informed each production step. The result was a map optimized for use in SAR operations on MMWD by the respondents. I certify that the Abstract is a correct representation of the content of this thesis.

  • Mt. Tamalpais Watershed Road and Trail Management Plan
    Preface The Marin Municipal Water District (District) has been caring for the Mount Tamalpais Watershed for nearly 100 years. At the heart of the District’s mission is the continued preservation of the highest quality water. As such, there will always be a need to manage the roads and trails on the Watershed in a manner that minimizes their impact on the creeks and reservoirs. This plan represents the first comprehensive plan for managing all of the Watershed’s roads and trails. The District, its staff, and consultants Pacific Watershed Associates (Wildland Hydrology and Geomorphic Services) and Leonard Charles Associates (Environmental Impact Analysis) hiked and scrambled over the entire Watershed and its hundreds of miles of roads and trails to develop this plan. Further, several public meetings and presentations were held throughout the preparation of this plan. Members of the public, many who are very knowledgeable and passionate about the Watershed’s roads and trails, provided valuable input and helped craft the final outcome of the plan. We extend our sincere thanks to all those who participated. In the end, this plan, which is a both a description of the official system of roads and trails and a detailed work plan on how to manage the roads and trails for the next quarter century, is a guide to further the protection of water quality in creeks and reservoirs, further the protection of environmentally sensitive habitats and special status species, and minimize road and trail related impacts on the Mt. Tamalpais Watershed. Prepared
