Dynamic Deployment and Mirroring of PostGIS Geospatial Data Repositories using Kubernetes, Helm and Other Open Source Technologies - a System Component-Based Approach to Geospatial Data Sharing and Publication Chris Mader, Timothy Norris & Julio Perez, University of Miami
Online GIS repositories (implemented using technologies such as ArcGIS Hub, for example) typically support two models for data access: data download; and API support. Here will we present a system component model for data sharing based on Kubernetes and PostGIS. We are using this approach at the University of Miami as part of the Frost Institute for Data Science and Computing (IDSC) Geospatial Digital Special Collections (GDSC) data resource. This approach enables the replication of fully functional sets of PostGIS databases combined with API services that can be used to build de-coupled software applications, as well as for other purposes where mirroring pieces of a repository is beneficial. We will also present a quick case study of an actual software application, that used replicated components, for illustration purposes.

Discovering and Explaining Ecological Connectivity
Mir Rodriguez Lombardo, Almanaque Azul foundation
Awareness of ecological connectivity has become critical in a rapidly changing world and increasing fragmentation of natural areas. I will talk about how we met the challenges of not only creating a high-resolution map of functional ecological connectivity for Panama, but also of how to effectively communicate the results. Making the map began by assembling various data sources, then surveying experts and finally many iterations of running the data through a connectivity algorithm (Omniscape). We interpreted the results informed by environmental threats, as well as local land and water defense struggles, then liaised with teachers to created a digital and paper map of "natural corridors" intended to be used in the classroom.

Handling Complex Content within Georeferenced Historical Atlases
Adam Cox, Healthy Regions & Policies Lab, UIUC
While georeferencing a single map is an easy one-off process, applying the work across a whole atlas (or multi-volume set) is a challenging task--especially when pages have multiple insets and the atlas contains more than one category of maps. How do you structure this work, and create cohesive output? This presentation will describe the novel hierarchical approach within OldInsuranceMaps.net, a crowdsourced web georeferencing platform designed around the complexities of Sanborn fire insurance maps. Facilitating the creation of seamless mosaics from this collection has resulted in a robust, abstract workflow that could be applied to any other maps or collections as well.

Using Old Maps for New Insights on America’s Cities
Riley Champine, University of Richmond
Given the widespread attention redlining has received in recent years, some might think studying old maps of housing discrimination has grown stale. But even after a decade of work by the University of Richmond's Digital Scholarship Lab (DSL), fresh documents, stories, and data continue to surface, leading to the release of the third version of their flagship project, Mapping Inequality. This talk will explore the latest features and design enhancements of the project website, illustrating how they add depth to an expanded collection of redlining documents. We'll also discuss the DSL's latest project and our efforts to incorporate detailed Sanborn fire insurance maps into the study of urban health disparities in redlined areas.

Continuing a Classic: Map Use, 9th Edition
Patrick Kennelly, Aileen Buckley, Esri; & Jon Kimerling
No other cartography textbook has withstood the test of time like Map Use: Reading Analysis, Interpretation. Since its debut in 1978―nearly a half-century ago―it has remained a stalwart companion for instructors, students, self-learners, and professionals. Map Use, 9th Edition, allows us to not only update the book with some of the best maps recently made, and produce the book in both print and e-book format, but it also provides us with a unique perspective into what has changed over the years―and what has remained the same. It allows us to evaluate what is currently most important in map use and mapmaking so that we can, in effect, present the state of the art in those areas of our field. Yet, for all that has changed over the years, the underlying philosophy of Map Use remains the same―a good map user must understand, at a basic level, what goes into the making of a map.
