Clustering Pushpins with the Virtual Earth Map Control API

One of the new features introduced in the Virtual Earth Map Control API is Pushpin Clustering. When there are hundreds of pushpin shapes on the map in a dense area, the map can become very cluttered. The pushpins can overlap each other and obscure the

Microsoft Research Releases Tiled Vectors Demo

Microsoft Research released a Tiled Vectors Demo which is available for download . The demo shows a way to solve the problem of showing extremely large mapping data sets in the web browser. If you have used the Virtual Earth AJAX/JavaScript Map Control

Virtual Earth API: Implementing Drag and Drop in Virtual Earth

Steve Lombardi posted some nice samples recently on the Virtual Earth Spaces blog showing how to implement drag and drop on shapes using the Virtual Earth map control API. You just need to add a custom event handler for the "onmousedown", "onmousemove",

Virtual Earth API: Bulk Adding Pushpins to a Layer to Improve Performance

One of the new features from the Virtual Earth v6 Map Control API is the ability to bulk add groups of pushpins to the map in one step. This improves performance when putting a large number of pushpins on the map since the HTML markup of the pushpins

Virtual Earth API: Setting Altitude of Shapes

The Virtual Earth v6 map control API added support for setting altitude of VEShapes in Virtual Earth 3D. There is a new SetAltitude method on VEShape which takes in 2 parameters: VEShape.SetAltitude(altitude, altitudeMode); The altitude parameter is the

Virtual Earth API: Accurately Position Points in Birdseye

In the Virtual Earth v6 API, one of the new features is improved Birdseye accuracy. The Virtual Earth v6 API has some new methods to more accurately position pushpins when in Birdseye view. Satellite (Aerial/Hybrid) and Road imagery views are direct overhead

Virtual Earth API: Creating Numbered Pushpins

Many people have asked how to create numbered pushpins using the Virtual Earth API. One way to do this is to have custom pin images with numbers in the image. However, you can also do this in the v5 API using VEShape and custom HTML and CSS styles for

Virtual Earth API: Importing Virtual Earth Collections into VEShapeLayers

The same way you can import GeoRSS Layers into VEShapeLayers , you can also import any public Virtual Earth Collection from Live Search Maps . It is very simple to do and is probably one of the easiest ways to create a Virtual Earth application. Steve

Virtual Earth API: GeoRSS Layers

The v5 Virtual Earth API has improved GeoRSS support. The Virtual Earth API now integrates GeoRSS Layer support with the VEShapeLayer. So, you can now load a GeoRSS layer feed and then access the items in that layer through the VEShapeLayer and VEShape

Virtual Earth API: Simple VEShapeLayer Example

One of the powerful features of the Virtual Earth v5 API is the new VEShapeLayer. The VEShapeLayer allows you to organize VEShapes into groups. In the previous VEShape example, the VEShapes were added directly to the map. When shapes are added directly

Virtual Earth API: Simple VEShape Example

The Virtual Earth v5 APIs added a new VEShape class to make it easier to create pushpins, polylines, and polygons. The new VEShape class gives these shapes a standard interface and a uniform way to create and access drawing elements on the map. VEShapes
