Visualizing data as circles in Google Maps Datasets that include geographic or spatial data (“geodata”) are often much easier to digest on a map. When each data point also includes a measure of size or catchment, it could be helpful to represent the point as a circle on the map, with the radius indicating its relative size. Here’s an example showing the UK car industry, which was created using the Google Maps API (screenshot): Source (zip) – all data is fictitious; runs locally in IE Notice that the circle radius (number of employees) and colour (status) are used to represent different aspects of each car plant. This makes use of the latest Google Maps API (v3), which includes the ability to draw overlays. The body of the HTML is just a single DIV element: The rest is all javascript. Loading the XML file We can use jQuery’s .ajax() method to load the XML file, followed by calls to .find() and .each() to iterate over the elements. Close your eyes for a second :-) function toXmlDom(data) {if (typeof data ! Displaying the map
Set map styles - Google Fusion Tables Help Locations in Fusion Tables can be points, lines or polygons. The appearance of each of these features on the map can be set with a map style. To change the appearance of map features: Style types There are four ways to specify a style: Fixed Specify a single style to be used for all elements on the map. Column Provide a specification for each row's display in one of your table's data columns. Buckets Specify two or more number ranges, and give each range a style. Gradient Polygons and lines are styled based on the numbers in your data. Legends For some styles you can automatically generate a legend explaining the map's appearance: Point marker styles using buckets Polygon fill color styles using buckets or gradients Use the Automatic legend panel to specify the legend to show (marker, polygon fill, or both) and where on the map to place the legend box. Try it yourself! Open a public table like the Caterpillar data. Need even more power?
Clever | Developer Docs Authentication All Clever API calls must be authenticated using API tokens. Specifically, OAuth 2.0 bearer tokens. API Tokens Clever uses token-based authentication because it offers numerous benefits over key-based authentication. A token represents the authorization that a district has given to access its data. This approach offers a number of benefits: Security: A compromised token represents a much smaller risk than a compromised API key.Simplicity: With tokens, scoping API calls to be within a single district is trivial.Embedded applications: The content of a token is shared between you and a single district, so it's safe to embed or expose the token to the district that granted it to you. Acquiring a token Every time a district authorizes your application, a token is created that stores the details of this authorization. 7f76343d50b9e956138169e8cbb4630bb887b18 You can acquire this token in one of two ways: Manually. Automatically via OAuth 2.0. Authenticating with a token API Keys Security

Google Maps API Receives Transit, Symbols, Heatmap Layers Google has made several modifications to its Google Maps strategy over the past few weeks that will encourage developers to continue to use the service. The new additions were outlined in a recent blog post made by the Google Geo-Developers team. (Photo: flickr.com / Johan Larsson) Google Maps, the satellite imaging service provided by Google, has become one of the most popular map services for a number of activities: whether it's mapping crimes in a city, available apartments or just finding a route from one location to the next, Google Maps has become the go-to service for many users. Follow Us Recently, though, Google Maps has come under fire by one of the search giant's biggest rivals, Apple Inc. Not to be outdone, Google has made several modifications to its Google Maps strategy over the past few weeks that will encourage developers to continue to use the service. "To support the launch of routing by public transit we're also adding the Transit Layer to the Maps API.
Khan Academy API · Khan/khan-api Wiki The Khan Academy API gives developers access to nearly all types of Khan Academy data via a RESTful API that outputs easy-to-parse JSON. Overview At the highest levels, the API will give you information about Every Playlist. Exercises and Videos are related, so you can ask make a specific api call to find out about a video like Absolute Value or you can ask for that video's related exercises. Similarly, you can ask about the Absolute Value Exercise and in much the same way as in the video example above, find the exercise's related videos. You can use these unauthenticated api calls to get information about nearly all of the Khan Academy's library organized in Playlists, or as individual videos or exercises. Authenticated api calls will give you information about the logged in user (either a student or a coach/parent), such as videos seen, exercises completed, playlist progress and so forth. Getting Started Methods Check out the API Explorer to see (and experiment with) all of our API calls.
Need to add "directions to here" link in infowindow Google Maps API Tutorial If you happen to have your data stored in some application that doesn't export XML files, you might prefer to output it as a plain text file. It's also possible to have an script running on your server which returns plain text data containing a different selection from the data depending on query information derived from what your users input. I'm not going to cover the server side of things in this tutorial. Here's a simple example You can see the file that I used here The code defines a function "process_it()" which processes the retrieved data. The entire data file is passed to process_it() as a single string, which we can then split into lines using newline (\n) as a separator. Care needs to be taken to avoid trying to split empty lines. Once all the data has been parsed, we can create the markers and the sidebar as in the previous examples. Note that the code to insert the assembled sidebar information into its <div> must be inside the process_it() function. Potential Pitfalls
Public transit routing and layer now available in the Google Maps API Google Maps API now enables developers to add Transit data, including public transit directions, to their maps and apps. Whether you're planning a trip from your computer or on the spur of the moment from your mobile device, Google Maps helps you find directions in more than 475 regions around the world. Today we're pleased to announce that public transit directions are now available in the Google Maps API. Public transit has been one of the most requested features by Maps API developers, and you can now use it in both the Google Maps Javascript v3 and the Directions Web Service. To support the launch of routing by public transit we're also adding the Transit Layer to the Maps API. If you're using a Google Map, you can now use the Directions API web service to add this useful and helpful transit data to your map.
