ArcMap Interface Standard Toolbar Status Bar Table of Contents – Lists layers (stacking order; like a legend) Data Frame (a group of layers) TOC Tabs – different display modes Data Frame display modes – “Data” or “Layout” ArcCatalog Map display Window (Data Frame)

Fundamental component of ArcMap Fundamental component of ArcMap Collection of data layers (in data frames) and a cartographic layout Collection of data layers (in data frames) and a cartographic layout Stores references to the locations of the data sources (e.g., shapefiles, coverages, image files, etc.) NOT the data themselves Stores references to the locations of the data sources (e.g., shapefiles, coverages, image files, etc.) NOT the data themselves Has.mxd file extension Has.mxd file extension Map Document
