How DataViz Sees Cartography
Presenter: RJ Andrews, Info We Trust
A data storyteller explores the connections and distinctions between data visualization and cartography. In some sense, everything is a map and everything is data. Yet the pursuits of data visualization and cartography can be quite different – especially as they straddle design tensions to serve clarity and context. Through dozens of examples from across time, see cartography in a new way: What cartography has given abstract statistical charts and diagrams. What data visualization still has to learn from cartography. And what cartography might learn from data visualization.

Distraction Free (Online) Maps
Presenter: Mila Frerichs
Our world is full of distractions and we as creators of (online) maps add to it. We create maps that overload our audience with information and hide important details in our maps.
People can only retain a limited amount of information and we should be mindful of that.
Let's be cautious if we need that basemap if we need all the extra information on the map. Or if we can use color sparingly and use annotations to help our audience to retain more information.
Let your data shine.

Exploratory Visualization of Massive Movement Datasets Derived from Social Media Data
Presenter: Alexander Savelyev, Texas State University
This paper presents the process and the results of an exploratory visualization of a massive movement dataset derived from a large (about 70 million records) collection of geographic social media data. We demonstrate the presence of clear clustering patterns in both temporal and spatial dimensions of the dataset that likely correspond to different modalities of travel, and explore the use of these patterns as interactive filters for the purpose of data exploration and analysis. We also perform a small-scale accuracy assessment of patterns observed in this dataset by means of comparing external travel records against their social media equivalents.

Drones, Maps, and Plant Conservation: Surveying and Mapping the Rugged Cliffs of Kauai
Presenter: Ben Nyberg
In the extreme cliff habitat of Hawaii, there are areas where native plants thrive. These locations have been a mystery to science due to their sheer inaccessibility. Drone technology has changed the equation and the National Tropical Botanical Garden is now surveying difficult-to-reach vertical surfaces for the first time. This presentation will cover the entire process from predictive analysis, image collection, post-processing via 3D maps and communicating results in online portals, all through the lens of protecting rare and endangered plants.

Object-Based Image Analysis Applications
Presenter: Geoffrey Forbes, LAND INFOWorldwide Mapping LLC
LAND INFO Worldwide Mapping is a pioneer in the use of object-based analysis of satellite and aerial imagery. We were founded in 1993 and began creating geodata solutions for wireless communication in 1996. Our 5G wireless mapping projects over the past two years led to our being named one of the fastest growing small companies in America. In addition to telecommunications, object-based image analysis has applications in urban planning, utilities, agriculture, forestry, ecology, change detection and more. This presentation will show specific objects extracted for particular uses, types of imagery used, and software and techniques employed.
