Using Definition Expressions in the AGIS API for Flex to Restrict Feature Display
In the first article in our series on the ArcGIS Server API for Flex we covered some basic concepts including how to create maps and add layers. We covered both tiled and dynamic map service layers. In this brief post you will learn how to apply a definition expression to your dynamic map service layer to restrict the features displayed from a layer. For instance, in the figure below we are plotting only those counties that suffered a population loss from 2000 to 2007.
ArcGIS Server Bootcamp – Coming in June
Join us this summer for our first ever ArcGIS Server Bootcamp! Beginning in June and ending in late August this self-paced, instructor led, Internet based course will teach you all the fundamental skills you need to fully take advantage of the new ArcGIS Server 10 platform. The course is self-paced and is designed to accomodate busy work and family schedules as well as summer vacations.
ArcGIS Server provides an integrated solution for managing, disseminating and analysis of GIS data. Starting with the basic concepts of ArcGIS Server and moving to advanced web application development techniques with JavaScript, Flex, or Silverlight you will acquire the skills necessary for publishing your GIS content to users over the web or through traditional desktop means.
We have space for only 15 students in this bootcamp so reserve your seat now.

The Google Maps team continues to add really useful functionality to the Maps API. Now the Google Maps API team has introduced a new Elevation Service that enables applications to determine elevation profiles. The Maps API v3 contains an ElevationService class or you can simply use the Elevation Web Service as an HTTP request from v2 applications. You can request the elevation in meters for one or more sets of coordinates, or you can request a specific number of elevation samples spaced along a path.
The figure below shows a sample application that uses the Google Visualization API to plot elevation profiles. You can add additional points by clicking on the map or entering an address, and you can switch between different modes of travel to see the affect on the profile. If you roll your mouse over the profile chart you can see on the map the point that the given sample relates to
I’ll have some code examples on this new service soon.
