Features: To facilitate users in developing geographic information systems (GIS) that meet their professional needs, major GIS vendors typically provide specialized languages alongside their basic GIS platforms. Examples include MapInfo's MapBasic, RSI's IDL, and ESRI's Avenue. This book introduces the secondary development of GIS using MapBasic and IDL in a step-by-step manner through numerous examples. Part 1 primarily covers how to use the MapBasic language to create and use user interface elements, control map objects, manage worksheets, operate files, select and query map objects, and integrate MapInfo maps. Part 2 explains how to use IDL for graphic and image processing, as well as how to develop applications with user graphical interfaces. When introducing each language, it starts with basic concepts and then progresses to demonstrate map display and geographic computation methods. This book is suitable for GIS researchers and developers in government and corporate departments, as well as students majoring in geography, geographic information systems, real estate, environmental science, resource and urban-rural planning management, and regional economics at universities. It also serves as a learning textbook and reference for GIS training participants.
