Birth of the 3D Elevation Program: How a Map Factory became a Big Data Producer

For over 130 years, the US Geological Survey (USGS) has been the nation’s premier governmental map making organization. Gone are the days of producing maps from topographic surveys, artistic sketches and printing on copper plates. Today’s topographic maps are derived from high resolution digital data designed to be consumed on a variety platforms. The need for high resolution elevation data is vast and increasing demand has led to the creation of the 3D Elevation Program.

New maps in the new medium: Teaching web cartography for a distributed workforce

Discussions of online education often center on pervasive media, which allow for immersive and distributed education. However, when the curriculum is explicitly designed to train students in the expert use of software and systems for web cartography, how might educators best realize these opportunities in online education? We discuss two challenges: 1.) how to teach distance learners a technologically-demanding, yet cartographically-focused curriculum, and 2.) how to design and implement this curriculum within a quickly shifting landscape of workforce needs?

Geospatial Innovation and the Rules of Engagement (Closing Session - Salon C & D)

This year’s keynotes carry notions of impending change for our industry: from "reaching a wide audience"(Julia Wolfe) and a need for "alliances between different open source communities" (Mark Munsell) to a "tsunami of spatial data" (Chris Holmes). We are urged to appeal to more demanding users, engage with other disciplines, and prepare for challenging technical demands. It is a call to arms for innovation. But how do we go about it?

MAPPING INTERACTIVE GEOSPATIAL LINKED DATA

Linked Data (LD) for geospatial data systems benefit from map interfaces for visualization. Although map interface capabilities such as plotting geographic coordinates retrieved with SPARQL queries are widely used, these forfeit the advantages LD offer for browsing a graph. The described project explores the challenges and initial solutions for developing and using a map interface to browse triple data.

Replace the Shapefile, an Introduction to the GeoPackage

This talk will provide an introduction to the OGC GeoPackage file format. It will discuss many of the advantages of the GeoPackage over the ubiquitous Shapefile for vector data as well as its use for storing raster data.

This talk will address compatibility of the GeoPackage with Open Source and Proprietary GIS solutions.

This talk will discuss how GeoPackage fits in with overlapping technologies SQLite, MBTiles, and Spatialite.
