Web maps

An ArcGIS web map is an interactive display of geographic information that you can use to tell stories and answer questions. For example, you may find or create a map that addresses the question, How many people in the United States live within a reasonable walk or drive to a supermarket? This map has layers showing which neighborhoods are within a 10-minute drive or 1-mile walk to a supermarket, and for context, the map has a topographic basemap that includes cities, roads, and buildings overlaid on land cover and shaded relief imagery.

Maps contain a basemap, a set of data layers (many of which include interactive pop-up windows with information about the data), an extent, and navigation tools to pan and zoom. Many maps also contain scaled symbols and other smart styling that reveal data as you interact with it. For example, a map can show the relative magnitude of earthquakes that happened over the previous 60 days.

You can create maps in a few basic steps and open them in standard web browsers, mobile devices, and desktop map viewers. You can share them through links or embed them in websites, and use them to create map-based web apps. When a map is shared, the author decides what to include with the map. For example, when the map is shared with the general public through Map Viewer or Map Viewer Classic, the map includes options to switch basemaps; view a legend (if the map contains one); view details about the map; share, print, and measure the map; and find locations on the map. Signing in to Map Viewer or Map Viewer Classic with an ArcGIS account may reveal additional options for adding layers, getting directions, and so on. Maps embedded in websites and shared through apps often contain a focused set of tools for a specific purpose, such as collecting information, editing features, or comparing two maps side by side.

Web maps can be used across ArcGIS because they adhere to the same web map specification. This means you can create web maps in one ArcGIS app and view and modify them in another. For example, you can create a web map in ArcGIS Pro and your colleague can modify it in ArcGIS Enterprise.
