Please explore this YouTube channel, Tips for GIS, created by Ahmad Aburizaiza, a Ph.D candidate in Geography at Mason. It provides various helpful videos to guide us. Topics include collecting Twitter geodata using CartoDB, creating ArcPy and Python to backup shapefiles, downloading Open Street Map data, getting GeoJson data quickly, and more.
University Libraries’ staff demonstrated how to visualize John Snow’s Cholera incidences that occurred in London 1854 in celebrating GIS Day 2015 at Mason. You can see the project through the interactive web mapping site: http://mason.gmu.edu/~aaburiza/snowCholeraMap/
We used three different methods to visualize the data to show a relationship between the death locations and the nearest water pump as following:
1) Creating a Spiderweb map-when you click on a water pump, all web lines associated with the death locations to the closest water pump; when you click on a pump, the spider web of the deaths for the clicked pump is also generated. In addition, when you click on a death incident, a line links to the closest pump. 2) Creating a Veronoi diagram map-a zone of each water pump is drawn such that all water pump are closer to one other. The death locations falling in each zone are then calculated to represent density of a thematic map, and 3) Generating a heat map to show hot spots of the death incidences.
Please click on each menu bar: Spiderweb, Veronoi, and Heatmap to enjoy the interactive web mappings of this project.
The system was built using Leaflet, Mapbox, and Turf.js in addition to Bootstrap, JQuery and HTML for the web design.
Please join University Libraries’ Data Service staff again in celebrating 2015 GIS Day. This year’s theme is GIS and Health. Check out cool demonstrations, presentations, and poster sessions and learn more about GIS. The library data service staff will demonstrate how to visualize geographical patterns of Cholera outbreak that occurred in London, England 1854 using CartoDB. See the complete program and schedule of the events hosted by the Department of Geography and Geoinformation Science : http://infoguides.gmu.edu/gisday/2015 or http://cos.gmu.edu/ggs
Time: November 18th, 10:00 am -2:00 pm
Location: Center for the Arts, Fairfax
Free Buffet Lunch: start at 12:00.
Come and learn to create maps and do geospatial analysis through the libraries’ GIS workshop series. We added new workshops such as ArcGIS Online (Oct. 9, 11:00-1:00), Python for ArcGIS (Oct. 22, 2:00-4:00) and Introduction to Web-Mapping (Oct. 21, 2:00-4:00) this Fall. Our existing workshops such as Introduction to GIS, Introduction to QGIS and Intermediate GIS are still available on Fridays.
Please check the schedules and the detailed description of the workshops through http://dataservices.gmu.edu/workshops . We also offer new statistical workshops such as R and SAS this semester. Please join us these workshops until you feel comfortable to use these powerful tools for your research.
ArcGIS 10.3 is now available on the data services lab computers (C 103 in Fenwick Library). Read more about What’s New in ArcGIS 10.3. At 10.3, ArcGIS Pro, new desktop application, is included so that you can do 3-D GIS projects and publish maps directly to ArcGIS Online. See more details about ArcGIS Pro at: http://pro.arcgis.com/en/pro-app/
