Leaflet allows you to do the basics, of course, such as popup an information window and overlay your own data. It can do far more than that and is a viable replacement for Google Maps. The functionality brought by Jason Sanford’s Leaflet Vector Layers is a real selling point for me. Geocommons are ArcGIS Online are two easy ways for people to get their data on the web. Leaflet Vector Layers then makes pulling that data into a web map simple. The Vector Layers plugin also makes Arc2Earth data available to you. Arc2Earth is a great tool for helping you move your data off of the desktop on to a cloud-based service. They have been doing some amazing work with storing geospatial data in Google Fusion Tables. However you share your data on the web, Leaflet can bring it in to a web map and display it. If it’s easy to code and produces something that is easy to use and aesthetically pleasing, it’s going to be a big success.
I am working on a project at Rowan where we are looking to make an interactive campus map that will zoom down to the room level, displaying floor plans of the buildings on campus. The flexibility and the cross-platform functionality of Leaflet means that I will seriously consider using this Library to power the user interface of the map. I was originally thinking about OpenLayers, but Leaflet seems powerful enough to do all that I require.

Long Live Mapquest!Posted: January 30, 2012 Filed under: Application Programming Interfaces | Tags: apis, mapquest, mapstraction, openstreetmap Comments Off on Long Live Mapquest!
Mapquest, the granddaddy of web mapping platforms, has been losing market share ever since Google Maps burst on to the scene. Google Maps’ tile-based (aka “slippy”) map interface and API caused many to adopt Google’s offering over Mapquest for integration with web sites as well as for daily use.
Mapquest has since turned over a new leaf and is offering a tiled map based off of OpenStreetMap data. Announced in 2010, the OSM-sourced map is just one of a few developer-friendly moves the company has recently made.
If you want to get started using Mapquest maps in your blog or personal web page, they have a simple to understand page on how construct your map using their Map Builder application. You can then embed maps into your WordPress blog using their plugin. If you want something more advanced, you can use their Open APIs to incorporate their OSM tiles and data into your application.
And if you don’t want to use Mapquest’s API as the framework for building your application, you can always use the Mapstraction library and still use the tiles and some of their other data services.
From the Mapstraction site:
Users can switch maps as desired based on personal taste and quality of maps in their local area. Various tools built on top of Mapstraction allow users to easily integrate maps into their own sites, and configure them with different controls, styles, and provider.
I plan to discuss Mapstraction more over the next few posts. With Google’s recent change to their API Terms, many are switching from the Google Maps API and Mapstraction will undoubtably play a role in some users’ transition schemes.
If you have no experience with web mapping, but have some basic website-building experience, you can begin to make interactive web maps fairly easily using Google’s mapping application programming interfaces (APIs).
