1 Intrductin t Prgramming ArcObjects using the Micrsft.Net Framewrk Three days Overview ArcObjects cmpnents are the building blcks f the ArcGIS family f prducts, and the ArcObjects libraries prvide a set f sftware cmpnents and a framewrk fr develping GIS applicatins. This curse intrduces the ArcObjects libraries t Micrsft.NET prgrammers and teaches hw t develp custm GIS applicatins. Yu wrk with ArcGIS Engine cntrls and.net develpment tls and learn hw t use help resurces. In curse exercises, yu wrk with the ArcObjects.NET develper resurces and ArcGIS Engine cntrls t create applicatins that perfrm specific GIS tasks including map navigatin, feature selectin and rendering, spatial peratins, data prjectin, data management, editing, geprcessing, and map creatin. Audience This curse is designed fr experienced Micrsft.NET prgrammers wh want t develp applicatins using ArcObjects. Prerequisites and recmmendatins Students shuld have cmpleted ArcGIS Desktp II: Tls and Functinality r Learning ArcGIS Desktp r have equivalent knwledge. It is mandatry that students have a basic prficiency with VB.NET r C#.NET befre taking this curse. Students in this curse shuld already knw hw t: Declare and use variables. Write functin and sub prcedures. Use cnditinal statements (If Then Else, Select Case). Wrk with lps. Create frms, add cntrls, and write event prcedures. Thse withut the requisite.net experience can gain prficiency befre taking this curse by wrking exercises in an intrductry third-party.net curse r tutrial.

2 Gals Thse cmpleting this curse will be able t Describe the architecture f the cre ArcObjects libraries. Illustrate the mst effective ways t use the cmpnents f the sftware develpment kit (SDK) and develper tls t implement custm functinality. Use ArcObjects t develp GIS functinality using.net. Custmize.NET frms with ArcGIS Engine cntrls. Write reusable cde fr autmating tasks in ArcGIS. Tpics cvered Getting started with ArcObjects: Classes, class libraries, COM, query interface. The ArcGIS applicatin framewrk: Custmize dialg bx, Visual Basic Editr. Wrking with maps and layers: Active data frame, layer prperties. Accessing data with ArcObjects: Accessing existing data using ArcObjects. Displaying data: Feature and raster data rendering. Wrking with queries and selectins: Cursrs and feature cursrs, selectin sets. Gemetry and spatial analysis: Spatial analysis, spatial reference, buffering. Data creatin and editing: Creating new data, editing using cursrs. Geprcessing: Running geprcessing tls, setting envirnments. Wrking with layuts: Making maps, adding elements, exprting and printing. ArcObjects beynd the basics: Extending applicatins, mre ArcGIS Engine, ArcGIS Server.
