\r\ni am currently working on a web mapping application using .Net web ADF. can any one tell me how to zoom the map to certain scale level. i.e. how to set or change the map scale programatically?

DevSummit

The DevSummit is less than two months away and there is still time to register for discounts. If you haven’t had the opportunity to check out the Dev Summit Web site or explore the sessions available here are a few that caught my eye.

ESRI Business Analyst APIs -- Putting Market Analysis into Your Apps

Python Scripting for Map Automation in ArcGIS 10

Using and Extending the ArcGIS WebMap for Flex

Developing Applications with the ArcGIS for iPhone API

Of course you should always check out the Web Mapping APIs sessions. We continue to add new templates, functionality, and samples. In addition, the participation among the community continues to grow as there are code samples and live published applications submitted by developers in the Code Galleries.   

Working with the ArcGIS API for Flex

 

Working with the ArcGIS API for JavaScript

Working with the ArcGIS API for Microsoft Silverlight/WPF

Keynote & User Presentations

This year the keynote will focus around platforms in the cloud. Last year, was the first time we allowed attendees to present at the DevSummit. This was definitely a hit and we have increased the amount of presentation slots available. User Presentations are selected through a voting process by the community (you) so if you haven’t voted or would like to view them I would recommend do so as last year there were great topics.  We hope to see you at the DevSummit.

I serve on the Education Team at ESRI and conduct many workshops throughout the year for educators in primary, secondary, community college, university, library, museum, and informal settings.  I make frequent use of the http://www.esri.com/mappingforeveryone site.  It provides an excellent way of introducing GIS, web GIS, choropleth mapping, and examining communities based on scale and 8 different variables.  I encourage you to do the same, and also share with the group what you are doing with this resource.

In case you haven’t heard, last week ESRI released a mashup/code challenge to the developer community. In the past, our challenges were only open to licensed ArcGIS or EDN customers, however, this challenge is open to all (no licenses needed) developers who meet the eligibility requirements.  All you need to do is build a mashup from one of our Web Mapping APIs (Flex, Silverlight, and JavaScript) and combine data from more than one source including content from ArcGIS Online.  You will also need to shoot a video of your application and post it on YouTube. The deadline for submissions is March 5, 2010 and you could possibly win one of the four cash prizes below.  Take the Mashup Challenge now.

1st Place: $10,000

2nd Place: $5,000

3rd Place: $2,500

4th Place: $2,500

','38169239'); threads[6] = new thread(4050495, 'Earthquake Sample', 'dmartinez', '12/15/09', '10:27 AM','

I just wanted to point out some interesting features and functionality of this sample application on the front page of the Web Mapping APIs. http://serverx.esri.com/arcgisjavascriptapi/codegallery/EarthquakePopulation.html

First, it takes advantage of some free services for noncommercial use available through ArcGIS Online such as the street base map, which is a cached tiled map service. It also uses some sample services that are published under our sampleserver1 through ArcGIS Online, including a dynamic map service for the population density polygons, a geoprocessing task to calculate the population within the 100 mile predefined buffer, and a geometry task to create the buffer (polygon graphic with geometries). All of these services and tasks are served up through ArcGIS Online and does not require the client application to perform any analysis or calculation, it is all done by ArcGIS Online.

Another interesting usage of a service is how it uses Yahoo Pipes to get the earthquakes from the USGS using GeoRSS feeds and returns it as JSON. The earthquakes are retrieved after the map loads and it populates the data grid with these results. To demonstrate some of the capabilities of the ArcGIS API for JavaScript the InfoWindow is used along with the InfoTemplate to show the attributes from the earthquakes. PictureMarkerSymbols are used as graphics to display the longitude and latitude of each earthquake.  The code is well documented and you can take away some good coding patterns as well as how to combine multiple services into a single application. If anyone has any applications they would like to discuss or post, feel free to upload them to our community.

Cheers,

David

','35925205'); threads[8] = new thread(3699342, 'Behind the Make a Map App', 'Jeff_Archer', '10/05/09', '09:18 PM','Hello everyone,

I recently worked with the ESRI web folks to put together the Make a map application - http://tr.im/APlT.  This was a fun application to build, and I hope you find it fun to use.

This is a prototype application intended to highlight the ArcGIS API for Flex, the great demographic data available from ArcGIS Onilne, as well as the "Map Sandwich" web map layering technique proposed by the ESRI Mapping Center Team - http://tr.im/APgF.

This forum thread is intended to allow for discussions of how this application was built, and to allow for community support.  Also, since the application is in beta at the time of this thread creation, feel free to contribute your suggestions for improvement!  How the application evolves from here is largely up to you, so let us know what you think.

The most interesting technical aspect of this application is the extensive communication between the HTML host page and the embedded ArcGIS API for Flex application.  A working sample that was used to build this application will soon be available in the web mapping API sample gallery.  Stay tuned!  I\'ll be sure to update the thread as soon as it\'s available.

enjoy,

Jeff Archer

We have just posted the training seminar on the Silverlight API. This is a free training seminar so definitely check it out. It covers everything you need to get started on using the Silverlight API. You can also download the samples used in this presentation to view some of the maps, components, and sample services offered by ESRI. If anyone should have any questions about these samples feel free to post a question to this thread.
