Data analysts must navigate increasingly large data sets, sometimes with billions or
more records. I present methods for interactive visualization of large data sets, following
the idea that perceptual and interactive scalability should be limited by the chosen
resolution of the information, not the scale of the data.
I first describe methods for interactive . . .
An introductory look at how to build and program your own custom GPS receiver or other field sensor logging devices using open source hardware and software.
As a practical example, we will walk through an Arduino-based, GPS data logger that has been assembled from open hardware components and uses a variety . . .
Langley is a small rural community on Whidbey Island in Washington State. Like so many other small rural communities, Langley is faced with limited resources but a great need to better understand the geospatial context of the local environment. Through the use of open source tools, including QGIS, GDAL/OGR, PostGIS, . . .
Learn how to build quick and easy open source mapping solutions using several different languages and datastores. Well start by selecting our source data, and a database to house it. Then, we’ll pick language and a simple microframework to power a basic REST API. Finally, we add . . .
OSGeo-Live is a Linux distribution, available in virtual machine, bootable DVD, or bootable USB formats, containing a curated collection of the latest and best Free and Open Source Geospatial (FOSS4G) applications. This talk investigates the correlations between worldwide download distribution, and community participation against indicators of economic, technical knowledge and . . .
ROGUE (Rapid Open Geospatial User-Driven Enterprise) was a project funded under the Joint Capability Technology Demonstration (JCTD) Program from the U.S. Department of Defense. Boundless and LMN Solutions, LLC implemented the project, with the Pacific Disaster Center (PDC) serving in the role of project Transition Manager. The project’s goal . . .
This project, originally inspired by the pop vs soda maps (www.popvssoda.com) seeks to create a web application where any question can be asked and answered by anyone with internet access. The Mapossum allows users to visualize spatial patterns in the questions they wish to pose without the need to possess . . .
JPL’s Airborne Snow Observatory is an integrated imaging spectrometer and scanning LIDAR for measuring mountain snow albedo, snow depth/snow water equivalent, and ice height (once exposed), led by PI Dr. Tom Painter. The team recently wrapped our second “Snow On” campaign where over a course of 3 months, we flew . . .
You can’t make a map without data. A wealth of free and publicly-accessible geospatial data exists on thousands of websites scattered around the world, just waiting to be found and used. But finding the right data for a specific map or analysis requires the knowledge of what geodata . . .
This session will begin with a status update for the MapServer project – current and future directions. Focus will then shift to the main features and enhancements coming in MapServer 7.0 including dynamic heatmaps, WFS 2.0 support, UTFGrid generation and more. Finally we’ll finish with a discussion of contribution opportunities . . .
