GIS INTEROPERABILITY DEFINITION • The ability of information systems to: • freely exchange all kinds of spatial information about the Earth and about the objects and phenomena on, above, and below the Earth’s surface; and • Cooperatively (over networks) run software capable of manipulating such information” (ISO 19101:2001) GIS INTEROPERABILITY – WHY AND WHERE IS REQUIRED? Geographic Enterprise GIS E-Government SDI Analysis with multi- GIS beyond Information Data isolated exchange within source data communities government Discovery Within Information GIS integration distributed exchange between Data into broader IT citizens and computing infrastructures Accessibility environment government Information exchange Data between business and government Integration STANDARDS • Standard definition: • “a document established by a consensus and approved by a recognized body, that provides, for common and repeated use, rules, guidelines or characteristics for activities or their results, aimed at the achievement of the optimum degree of order in a given context” (ISO 19101). STANDARDS • De jure standard: standard adopted by an official standard setting body (national or international) • De facto standard: a standard that has not received the sanction of any official body, but has imposed itself by eliciting a consensus among users, a group of firms or consortium www.the- ark.org PRINCIPALS OF STANDARDS The principals of standards can be summarized as follows : • Maximize End-User Choice • Extension • Royalty or free • Prevent Predatory Practices ISO/TC 211 GEOGRAPHIC INFORMATION/ GEOMATICS • Overall goal of ISO/ Technical Committee 211 • Standardization in the field of digital geographic information • ISO 19100 series of geographic information standards • Specific objectives: • To support understanding and usage of geographic information • To increase the availability, access, integration and sharing of geographic information • To enable interoperability of geospatially enabled computer systems • To contribute to a unified approach to addressing global issues (global ecological and humanitarian problems) QUESTION … • What‘s the name of your national organization reponsible for developing standards in your country?

    Minghini et al. Open Geospatial Data, Software and Standards (2020) 5:1 Open Geospatial Data, https://doi.org/10.1186/s40965-020-0074-y Software and Standards EDITORIAL Open Access Geospatial openness: from software to standards & data Marco Minghini1*, Amin Mobasheri2, Victoria Rautenbach3 and Maria Antonia Brovelli4 Abstract This paper is the editorial of the Special Issue “Open Source Geospatial Software”, which features 10 published papers. The editorial introduces the concept of openness and, within the geospatial context, declines it into the three main components of software, data and standards. According to this classification, the papers published in the Special Issue are briefly summarized and a future research agenda in the open geospatial domain is finally outlined. Introduction Army Construction Engineering Research Laboratories, The Open Definition qualifies knowledge as open “if while in the 1990s the history of Web Mapping began anyone is free to access, use, modify, and share it — sub- with MapServer (https://mapserver.org), originally devel- ject, at most, to measures that preserve provenance and oped by the University of Minnesota. The success of openness” [1]. This definition, derived from the Open both projects as well as the communities they were able Source Definition [2] which is specific to software, puts to attract explain the important role they still play today forward the idea of a common good based on access to in the open source geospatial arena. The establishment information that everyone can benefit from. This vision in 2006 of the Open Source Geospatial Foundation of a so-called ‘Open world’ is brilliantly invoked by Pol- (OSGeo, https://www.osgeo.org), dedicated to the devel- lock, who calls for an open revolution – where everyone opment and support of open source geospatial technolo- would have the freedom to use, enjoy and build on gies, was the key milestone to certify the maturity of everything – in a digital age where most information is open geospatial software and the related community.

Course Overview This course focuses on the advanced topic in geographic information systems (GIS): Internet GIS. Internet GIS is a network-centric GIS technology that uses the Internet and the World Wide Web as a primary means of providing access to the functionality (i.e., analysis tools, mapping capability) of GIS and to the spatial data and other data needed for various GIS applications. It provides users capability to work interactively with maps and conduct spatial analysis on the Web. It has many applications in urban planning, e-government and e-business. There are two goals of the course. The first one is to offer you theoretic background so that you will have a better understanding of the concepts of Internet GIS, such as how Internet GIS works, the different architecture models, and the state of art of the Internet GIS technology. The second goal is to offer you hands-on experience to use Internet GIS programs so that you can gain necessary skills to work with Internet GIS programs. The course will start with an introduction to networking basics and the evolution of software architecture, specifically the client/server model.

Gone too soon but forever in our hearts. ii ACKNOWLEDGMENTS I would like to thank my family for their continued support throughout my graduate coursework and thesis writing. Knowing the time you have allowed me to pursue my dream of finishing my master’s degree resulted in time not spent with you all. I hope for my three boys that you can now see that going to school when you are passionate about something is worth all the hard work. Thank you to all my teachers at USC, but especially Dr. Darren Ruddell my thesis chair, and my committee members Dr. Jennifer Swift and Dr. Robert Vos. You made this process a whole lot easier with your continued support and guidance. To Steve McGrath, Supervisory Engineer of the Veterans Affairs Palo Alto Health Care System, who supported this project throughout the entire process. Thank you also to Joanna Fong for her continued assistance and feedback. Last, but not least, to my husband Dave.
