type var rap ic = new esri.G Mashups and new esri.layers.ArcGISTiledM ServiceLayer = Mobile Solutions Code challenge contest expands By Matthew DeMeritt, Esri Writer This year developers could impress and inform their peers and compete for cash prizes by submitting original code samples in not one, but two, contests. The ArcGIS Code Challenge has been part of the Esri Developer Summit since the conference began in 2006. This year's contest was split into the ArcGIS Server Mashup Code Challenge (using the ArcGIS Server APIs) and the ArcGIS Mobile Code Challenge (using the ArcGIS Mobile Software Development Kit [SDK]) to better represent the multiple development environments available to developers on the ArcGIS platform. The Esri developer community—Esri Developer Network (EDN) subscribers, business partners, and selected current and past attendees of the Developer Summit—selected the two winners for each contest from a total of more than 30 entries. The winners were announced at the 2009 Esri Developer Summit. ArcGIS Server Mashup Code Challenge Alper Dincer, a Web developer at the Ministry of Environment and Forestry in Ankara, Turkey, won first place and the $7,000 award for his entry, Summit ExtMap—Mashup Framework. His application is a mashup framework based on Ext JS Framework, Google Maps API, and the ArcGIS API for JavaScript Extension to the Google Maps API. With this application, users can add and remove layers supplied by ArcGIS Online and select basemaps from Google and Microsoft Virtual Earth. The application's well-designed user interface offers tools that perform geocoding and reverse geocoding, find altitude by clicking on the map, add data/services, query layers by attributes, and configure map settings. "The main goal of our mashup is usability rather than performance, and the inspiration point was ArcGIS Desktop ArcView," says Dinçer. "We wanted to make a primitive Web version of ArcView. I hope both developers and users download the source code, use it in their projects, and share their ideas about it with us." Matthew Petre, a software developer at Petris Technology in Houston, Texas, won the second prize and $3,000 for his Flex Viewer Dice Job Searcher Widget. He created this application in eight hours using the ArcGIS API for Flex. It allows users to search for job postings using 42 ArcUser Summer 2009 c. eat reType == esr Strin IServer ect tensi nM sing ttp serverapi.arc is nline.c script src= See Alper Dincer's first place ArcGIS Server Mashup Code Challenge entry, Summit ExtMap— Mashup Framework, in action on YouTube (/www.youtube.com/watch?v=kVc3RR2KDZY).
