LET'S GET TOGETHER AND MAP AT MAPTIMESTJOHNS! Tuesday, April 29th, Anna Bannana's StJohns (8716 N. Lombard, Portland, OR,back room) from 7:30pm to 9pm.

This month at MaptimeStJohns, we will review some web spatio-temporal visualizations, using open layers, leaflet, weave and other open source software.

This month at MaptimeStJohns, we will begin programming a basic web spatio-temporal visualization, bring a computer if you have one. Ill bring the js library files for leaflet and the various plugins we will be using. If you have a temporal dataset, bring it... Ill have a couple of datasets to choose from though. Our goal will be for everyone to create at least one temporal point visualizations. An example would be the point locations of where floods occurred with the location, size of flood and date of flood event. With this data we could create a temporal proportional symbol map. The user will be able to click on the locations for specific locations and also use a slider to see when and where floods occurred over time. Let's create some cool web map visualizations!
