Programming Open Source Web Spatio-Temporal Mapping Visualizations, MapTimeStJohns, Tue, July 29, 7:30pm to 9:00pm, Anna Bannanas coffee shop, 8716 N Lombard St, Portland. Let's get together and map :) (We meet in the back room)

In June, we worked on creating a basic static map of floods with custom icons showing the size of the floods (a proportional symbol flood map). We went through a demo for using a slider to add amimation to a map... using the flood data it would allow users to see where and when the floods appeared.

In July, I'll bring a completed example of a proportional symbol animated slider flood map that we will review. In addition, we will add one or two other techniques for developing spatio-temporal web visualizations (in leaflet and open layers). Then we will begin using Postgresql/postgis to setup spatial databases, populate them and perform spatial analysis operations.One of our long term goals will be to eventually use data from a spatial database in dynamic spatio-temporal visualizations.

In July, bring your computer. If you have time prior to the meeting, load postgresql/postgis version 9.1 or later onto your computer.

Programming OS Web Spatio-temporal Mapping Visiualizations: Tues, Dec 30, 7:00pm, Anna Bananas St Johns, 8716 N. Lombard, Portland, Oregon (back room). This month we will work with OpenStreetMap Data. We will use JOSM to edit OSM data and learn to download OSM data for use in our web visualizations.

NOTE: we have a new time ... we will begin at 7pm and go to 9pm. If you are late, come anyway. We will be in the back room mapping away :)

This event is a social gathering for developers to discuss the latest in mapping, geo technology, geo services, web and mobile mapping apps, app design, cloud solutions, map data or anything else related to solving real-world "geo" problems.

Developers of all levels of expertise are welcome, from seasoned GIS professionals to those new to geospatial development. At these meet ups, you can:

• Meet cool people. Duh, we're there.

• Show us what you got by demo'ing your application or framework.

• Make a name for yourself in presenting an cool new/interesting concept or idea.

• Impress someone by sharing your experiences.

• If you're sharp with your GIS and developer trivia, you can win some cool Esri swag

• Make BFFs for life - connect with other developers!

Here's what's on the agenda:

5:30 - 6:30 PM Registration and Social (Appetizers and Beverages served)

6:30 - 7:30 PM Intro

7:30 - 8:30 PM Lightning talks

8:30 - 9:30 PM Raffle, Networking and Social. Two great prizes:

• A voucher for 1000 Service Credits for your ArcGIS Online Developer Subscription

• DevSummit Registration

Monthly meeting of the Portland open source GIS group. Projects big and small are usually presented monthly along with rousing conversation and discussion. All are welcome, no need to RSVP - our group ranges from the geo-curious to the überhackers so bring your ideas and questions!

We have a couple of really interesting topics this month:

• We'll check out "Mapping Inequality" [1], a project out of University of Richmond, University of Maryland, Virginia Tech and John Hopkins. The project uses Leaflet and CartoDB to display georeferenced maps and redlining data from in the late 30's - with a focus on redlining and abrasive, unfiltered racist language that has directly influenced the formation of neighborhoods today.

• We also have a very cool spatial analysis presentation from Kevin that will show how he used PostGIS, QGIS and Geopy to calculate the most remote locations in Oregon and Washington, along the lines of what Project Remote [2] has been doing for the whole lower 48. Kevin's project also used Leaflet, MapboxGL JS and Turf for visualization.

We'll also cover the latest happenings in geodata, upcoming geoevents and bring your own geo-show and tell, so if you see something interesting in your geo-travels be sure to bring it along to share!

As always, there will be pizza! And BYOB is always welcome.

This month our special guest is Jackson Voelkel, a Health Data Analyst on Kaiser Permanente’s GIS Team as well as an Adjunct Professor of Geography at Portland State University. He focuses on developing infrastructure for and performing advanced spatial analytics across healthcare, environment, urban planning, utilities, and econometrics. Jack will be joining us to talk about all this PostGIS (and Postgres), so come ready with all your favorite spatial database questions.
