Tonight at MaptimeStJohns, we will review some compiled leaflet maps using several of the leaflet pluggins. We will go through some live custom examples using humangeo's dvf pluggin, we will use postgis and output geojson, geocsv and topojson to add to our leaflet maps, and also discuss some temporal mapping tools.

Bring your laptop with leaflet installed and a webserver available. Have a server scripting language such as php or python and postgressql/postgis installed. If you don't have a laptop, come anyway and you will be able to see these tools in action, as well as receive any materials handed out at the meetup. Bring a flash drive so you can take a copy of the data home.

LET'S GET TOGETHER AND MAP AT MAPTIMESTJOHNS!

The Esri GeoDev Meetup is back again, and this time it is organized around a theme of biking! That means the intro, keynote, and lightning talks will all be focused on usages of GIS development within the context of biking and cycling.

Join us on Wednesday, April 3rd for this biking-themed meetup. Food and beverages will be provided.

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, map data or anything else related to solving real-world "geo/biking" problems.

Developers of all levels of expertise are welcome, from seasoned GIS professionals to those new to geospatial development.

Have you done research around or built a cool biking app recently that you'd like to show off? Submit a lightning talk! We'd love to see it!

• Meet fellow PDX techies.

• Show us what you got by demoing your application or framework.

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

• Impress others by sharing your experiences.

• Make BFFs for life by connecting with other developers!

• Win some cool Esri swag! (Mike and Eli are already hard at work conjuring up their best bike trivia.)
