Mapping Maryland State Assessment Pass Rates

We recently completed an interactive map displaying Baltimore Region school pass rates for the Maryland State Assessment (MSA).  The MSA is administered to elementary and middle school students to evaluate their proficiency in reading, math, and science. Click here to view and explore the map. The map was developed using GIS software Google Fusion Tables, and the Google Maps...

Arduino & Pusher-Powered Remote Control Hexbug

Control the hexbug live at http://www.jfxart.com/hexbot. Hopefully the lights are on, the batteries aren’t dead, and nobody else has walked the robot off the desk! After success with the Arduino Air Conditioner Remote Control, and getting Pusher authentication and client events working from an Arduino, I was in search of something a bit more fun and interactive to connect to...

Prezi Presentation on 3D GIS mapping with Open Data and ArcGlobe

Charm City Networks Co-Owner Chris Whong spoke during the Baltimore Neighborhood Indicators Alliance‘s Data Day last Friday, presenting a few examples of what is possible when combining civic data with 3D GIS extrusion tools, such as ESRI’s ArcGlobe and ArcScene. The Prezi presentation is embedded below, for those who wish to view it. Contact us for more information about...

City Paper Publishes Our GIS Map

 A 3D GIS map created by Chris Whong was published in today’s City Paper under the Info Art section.  The map shows the U.S. Census’ data for Median Household Income in each census tract of the Baltimore-Towson Metropolitan Statistical Area. In addition to color coding, each tract is extruded above the surface of the earth relative to its median...

Sending Pusher Client Events from an Arduino

A few weeks ago, I got my first arduino and set out to make my window air conditioner web-remote-controllable. Following some examples online, I created an Ethernet Server that displayed a simple web page with a power button. Clicking a button on the page simply reloaded it with “?status=1” in the URL, and the arduino pulsed the power button....

Web-controlled Window Air Conditioner Using an Arduino

It’s done. It works. The internet of things has come to my little apartment in New York City. After about a week of tinkering, soldering, and piecing together bits of code from here and there, I can now load a web page from any browser, see the current temperature in my apartment (and a graph of the last 12...

Municipal Broadband: A Need for Federal Policy

This paper was written in May 2012 for Intelligent Cities, a Master of Urban Planning Elective Course at New York University’s Wagner School of Public Service.  The first paragraph is presented below, the rest of the paper can be downloaded as a PDF. Crucial to the idea of smart cities is a municipality’s ability to quickly move information across...

Mapping Open Data: Baltimore City 311 Calls

What can you do with Open Data?  Make awesome maps, of course!  This map was created using Baltimore’s Open Data for 311 Calls.  Each call has a street address associated with it, which was geocoded and then spatially joined with BNIA’s shapefile for Baltimore Neighborhoods.  This is simply counting the number of 311 requests by neighborhood, but much more is...
