- When we ask people about maps this is often what they think of. Something that shows where things are, where they are, how to get from here to there. And while that’s great for finding and navigating, what happens if we want to show something about a place that’s more than just an address?\n
- So I want to introduce you to a word that’s always fun to say. “Choropleth.” Basically a fancy way of describing a map where different colors or shades tell you something about that place.\n
- They can help people understand public policy\n
- They can be a way to compare where you are to places around you\n
- They can help make show trends and patterns\n
- So now the big question, how do we get there from here?\n
- So let’s talk about the easiest way first. \n
- Most client side tools are pretty similar. They use Javascript inside the browser to show and color the map. They are made to be fairly easy to work with most have a Drupal module or two already written to take advantage of them.\n

- Free, not open source; limited customization but is fast and works in all browsers. \n
- Native Drupal module, completely customizable shapes.\n
- Free and open source; customizable shapes. Doesn’t work in older versions of IE.\n
- Since all of these run completely in the browser it is dependent on the user’s computer. Older computers and older browsers may be slow using these. Most of them also only show shapes, so if you want to layer address over top it will only work in Google Geo Charts. And people can’t zoom or pan in a way they may be used to.\n

- These services are designed to make creating a wide variety of maps as easy as possible. They accept a range of inputs and allow significant customizations. And they are intended to be used not just by programmers but also by people with less technical knowledge. \n

- The Tilemill application is usually run on your desktop. You can input common data sets such as country or state and then customize colors, labels, lines using a CSS-like language. You then upload the final map to...\n
- The Mapbox hosting service where they can be embedded on the site. It’s been heavily used on both the new energy.gov and fcc.gov sites.\n
- If you need to create more dynamic maps CartoDB is a new site that allows you to upload and manage your data and then convert that directly to maps through their website.\n
- These maps can be customized using a CSS-like language and then easily exported and embedded on your site. \n
- Like CartoDB Google Fusion Tables allows you to import and edit data directly within their site and then change it to be a map\n
- Which can then be combined with other Google Maps functionality. \n
- The disadvantages for these services are the same as any software as a service. When you select one you choose a direction that may be difficult to reverse. Similarly any data you upload is outside your immediate control and the infrastructure that supports the service is managed by the service. \n

- Which brings us to the most difficult of the three approaches.\n
- This involves hosting and typically developing custom code to do what you need it to do. And with that you get the ability to make any changes you want, have the maps pull data from custom data sources, do custom transformations before it’s visualized. You also ensure that the underlying data is where you need it to be. And lastly it will be running on your infrastructure, so whatever you need to be able to support you can easily provide.\n

- There are some components that you’ll need:\n* A way for the user to interact with the map\n* Something to actually create the map -- Mapnik is a common component with a lot of momentum\n* A web server to send the map out -- both CartoDB and MapBox have their code available on Github\n* A place to store this geographic data\n

- What’s amazing to see is the pace of progress with these tools. Even as far back as a couple of years ago they were so much less mature. The ability to write a little bit of scripting, to sign up a service or -- even if you choose to do it yourself -- to stand on the shoulders of giants and make their work somewhere you can start from is amazing. Geographic context can turn information that’s just a set of numbers in a table to something more meaningful, more personal, more immediate. And now the ability to do that is easily within reach.\n
