CartoCSS vs GL: Considering New Technologies for National Park Service BasemapsTaylor Long, National Park Service / Colorado State University
NPMap builds tools for the National Park Service that empower park staff to create functional, well-branded, digital maps. One of our primary products is Park Tiles, a suite of online basemaps designed for NPS using the CartoCSS approach. New developments in WebGL are expanding the possibilities of map design, display, and interaction. However, deciding if and when NPMap transitions Park Tiles to this new framework requires consideration of impacts on existing workflows and on the end users of our tools. This talk will highlight NPMap's exploration into the new word of GL basemaps, focusing on our team's considerations for if, when, and how the National Park Service will adopt this new cartographic technology.
The Ten Commandments of Interactive Web Map DesignRobin Tolochko, Uber
What are the dos and don'ts of making an interactive map? What are different things to consider for different mapping scenarios? What do you need to think about when designing mobile maps? I talked with a bunch of professional mapmakers about how they make interactive maps and, from those interviews, created a comprehensive list of best practices and conventions for designing maps for the web.

An Open-Source Approach to Creating a National Critical Habitat Web Map
Deanna Sarro, The Pennsylvania State University
U.S. federal agencies are required to consult with the Fish & Wildlife Service to ensure that their actions will not put at risk the survival of endangered and threatened species. Understanding the geographic locations of critical habitats provides these federal agencies with knowledge to make informed decisions as to whether and to what extent actions may impact these listed species. This presentation showcases a web application intended to aid federal agencies in this regard by providing a map showing the critical habitat spatial data, a listing of all endangered and threatened species attributes, and additional information about each species. Development of the map required consideration of different options for data format, application program interface, and plug-in libraries using open-source data standards and software. Additional functionality was included to provide graphical and spatial analysis of the critical habitat data itself and through queries against other related thematic layers.
Maps are Fast and So Can You -
10 Minute TalkSam Matthews, MapboxMaps on the web are in constant flux; technologies change, renderers improve, and data storage formats become more standardized. In order for a full mapping infrastucture to perform at its best, a huge number of updates are required at all depths of the stack, not just on the browser. Tools such as Mapbox GL JS are getting faster and faster, but that doesn't come without major changes to the underlying technologies at Mapbox. This talk will outline the major core improvements around GL-based maps at Mapbox, including work around the Vector Tile Specification, vector tile encoding performance, and the latest decoding & rendering improvements in Mapbox GL JS. It will conclude with notes on how to incorporate these tools into your workflow.
