ArcXML Overview

ArcXML is a powerful XML-based language used to define map configurations, metadata, and various requests and responses for ArcIMS (Arc Internet Map Server). This guide offers an overview of ArcXML functions such as GET_IMAGE, GET_FEATURES, GET_GEOCODE, and more, along with sample requests and responses. For hands-on practice, users can explore a sandbox environment and access additional resources to enhance their understanding of ArcXML's capabilities in mapping and data management.
