Esri Launches National Green Infrastructure Initiative for Planning Esri, the world leader in geographic information system (GIS) technology, has launched a suite of public mapping tools and data to help communities protect the places and natural resources that help people, wildlife, and the economy thrive. Leading the Green Infrastructure for the U.S. initiative, Esri has partnered with National Geographic Society to transform how U.S. communities plan development. By equipping local, regional, and urban municipalities with data and GIS tools, Esri president Jack Dangermond envisions communities working together to build a green infrastructure—a strategically managed network of open spaces, watersheds, wildlife habitats, parks and other areas that deliver vital services and enrich quality of life. With Esri’s green infrastructure planning tools, communities can identify, protect, and connect local places of natural and cultural significance before development occurs.

How We Created Color Scales — Interactive Things — Medium Introduction This article is about creating refined color scales for charts and visualizations. You will get insights from, and a deeper view into, our working process at Interactive Things. For us, a diverse and balanced palette is one of the key components to efficiently communicate information trough color. A list of the used tools can be found at the end of this article. The Briefing
Computing and visualizing PCA in R Following my introduction to PCA, I will demonstrate how to apply and visualize PCA in R. There are many packages and functions that can apply PCA in R. In this post I will use the function prcomp from the stats package. I will also show how to visualize PCA in R using Base R graphics. However, my favorite visualization function for PCA is ggbiplot, which is implemented by Vince Q. Vu and available on github. SVG Crowbar A Chrome-specific bookmarklet that extracts SVG nodes and accompanying styles from an HTML document and downloads them as an SVG file—A file which you could open and edit in Adobe Illustrator, for instance. Because SVGs are resolution independent, it’s great for when you want to use web technologies to create documents that are meant to be printed (like, maybe on newsprint). It was created with d3.js in mind, but it should work fine no matter how you choose to generate your SVG. The Bookmarklet

Using GIS to Form Resilient Public Health Plans As Negative Health Effects from Climate Change Grow, Sophisticated Technology Will Guide Preparation By Alex Philp, PhD, Upstream Research, Inc. The earth's climate is changing, and this will have a tremendous impact on human health. But the relationship between climate change and health is complex.
Design and Redesign The technique of “critique by redesign” in some ways works uniquely well in data visualization. A movie critic can’t remake a movie. An art critic can’t ask the subject of a portrait to sit for a second time. A book critic may be able to rewrite a sentence, but not a whole book. Index. ggplot2 0.9.3.1 Geoms Geoms, short for geometric objects, describe the type of plot you will produce. geom_abline(geom_hline, geom_vline) Lines: horizontal, vertical, and specified by slope and intercept. geom_bar(stat_count) Bars, rectangles with bases on x-axis geom_bin2d(stat_bin2d, stat_bin_2d)Add heatmap of 2d bin counts. geom_blankBlank, draws nothing.
