The satellites which comprise NASA’s Earth Observing System (EOS) have a long history of capturing rich datasets with global coverage over extended periods of time. While the data itself is rich (and open!), it can be a daunting task for uninitiated users to find suitable datasets, learn the data . . .
Vizzuality went from a data communications consulting company to the creator of one of today’s most popular online mapping frameworks, CartoDB. Four years ago, we recognized a major problem in open source geospatial tools, they were still prohibitively difficult to use to creating dynamic, interactive, and beautiful online maps. That . . .
We will demonstrate the use of WMS and WCS as input to three.js for rendering an interactive 3D-model in the browser, based on actual data. Our extension of three.js, (WxS.threejs) takes several inputs, the boundingbox being the simplest. WMS-service, WCS-service, LAYERS and many, many other variables can be set either . . .
This paper is a case study of FirstToSee, the social media situational awareness project organized by agencies in the Puget Sound region of the Pacific Northwest.
The purpose of FirstToSee is to capture, analyze and map social media using open source tools. The desired result is improved situation awareness through a . . .
Maps and stories go together like two peas in a pod. Why is that and how do we take advantage of it? Through my work at CartoDB, I have been able to think deeply about the role of storytelling for today’s map makers. Here, I will talk about the insights . . .
The National Park Service has many well-known sites, but many parks do not have the GIS resources to maintain their map data. The Places project aims to solve this problem by empowering non-technical park employees and the public with the ability to make changes to the map. The Places project . . .
The National Weather Service is developing several geospatial forecast visualization and analysis tools. The back end data store and WMS server is built on Open Source GIS tools: GDAL, PostGIS / Raster, Mapserver, and Mapcache.
Weather forecasts are in a constant state of flux. In the case of . . .
The North American Forest Dynamics (NAFD) project is completing nationwide processing of historic Landsat data to provide annual, wall-to-wall analysis of US disturbance history over nearly the last three decades. Because understanding the causes of disturbance (e.g., harvest, fire, stress) is important to quantifying carbon dynamics, work was conducted to . . .
GeoNode is a web-based extendable platform for the management and publication of geospatial data. It brings together mature and stable open-source software projects under a consistent and easy-to-use interface allowing users, with little training, to quickly and easily share data and create interactive maps. This talk will be a . . .
Google Analytics is a great tool for monitoring and reporting on website traffic and user interactions but what it doesn’t tell you is that 75% of the time your user’s zoom in two levels every time they start to use your map or that external soils layer you added is . . .
