With a projected attendance of one million people, the city planning to shut down for three days and the heart of Philadelphia behind a security fence, the first thing residents wanted was a map. Unfortunately, due to security concerns, the city was not permitted to publish an official web map - announcements from more than eight state, local and federal agencies were released with...PDFs. With no map a few weeks beforehand, we got to work: tracing layers, building a timeline and styling layers.
Web Mapping Day
This tutorial will introduce you to the major features of TerriaJS and show you how to use it to build your own map applications for the web. Without writing any code or deploying anything, you will be able to offer your users a rich catalog of geospatial data to explore, and enable them to visualize it in 3D.
The latest release of GeoServer adds support for creating Vector Tiles in GeoJSON, TopoJSON, and MapBox Vector Tiles format through its WMS service for all the vector data formats it supports. These tiles can be cached using GeoWebCache (built into GeoServer), and served with the various tiling protocols (TMS, WMTS, and WMS-C). Thanks to very recent OpenLayers 3 development, these Vector Tiles can be easily and efficiently styled on a map.
Our climate has changed and is continuing to do so. Communities are adapting our built environment to the new climate realities, but want guidance toward the future. Some of the climate change impacts community leaders want to know about include:
What is this GL maps thing? What are vector tiles again? How did we get here and where are we going? This talk will provide a (very brief) history of open source web mapping technology and a (comparatively longer) overview of what's to come. Most importantly, this talk will focus on why the future of web mapping is important and how we can all contribute to its success (beyond just contributing code). Beginners very welcome!
Have you seen georeferenced historical maps online that just look...fuzzy? That’s what we started with at the Emory Center for Digital Scholarship, and we would like to share the steps we’ve found to get clear, legible, zoomable map overlays.
Let's go from zero to web map in a just a couple of hours.
In this tutorial session, we will use only free and openly available tools to create our first web map and post it publicly for the world to see.
After a quick primer covering the components that make up the modern web map, we will:
