ArcView GIS Developer's Guide offers readers one of the most complete and widely used introductions to Avenue, ESRI's proprietary programming language for ArcView GIS, available anywhere. Newly updated and written to ArcView GIS 3.2a, this edition begins with an explanation of the object-oriented programming concept. From this starting point, readers proceed directly into practical demonstrations, examples of programming code, and tutorials engineered to lead them through the steps required to customize the ArcView GIS interface; create, edit, and test scripts; produce hardcopy maps; and integrate ArcView GIS with other applications. Coverage of Avenue fundamentals meets the needs of the novice, while individual chapters on Dialog Designer and programming Spatial Analyst benefit even the most experienced programmer. Familiarity with GIS as a data visualization tool is assumed, yet no prior programming experience is required to use this combination how-to and reference manual as a guide to optimizing the power of today's most popular GIS desktop tool!
