ArcGIS Explorer

ArcGIS Explorer is a free, downloadable GIS viewer that gives you an easy way to explore, visualize, and share GIS information. ArcGIS Explorer adds value to any GIS because it helps you deliver your authoritative data to a broad audience.

With ArcGIS Explorer, you can

  • Access ready-to-use ArcGIS Online basemaps and layers.
  • Fuse your local data with map services to create custom maps.
  • Add photos, reports, videos, and other information to your maps.
  • Perform spatial analysis (e.g., visibility, modeling, proximity search)

See demos of some of the activities you can perform with ArcGIS Explorer.

Access freely available mapping services.

  • Access 2D and 3D mapping services from ArcGIS Server; ArcIMS; and Open Geospatial Consortium, Inc. (OGC), WMS.
  • Add local data such as geodatabases, shapefiles, KML/KMZ, GPX, and raster formats (JPEG 2000, GeoTIFF, MrSID). You can also add layer packages created using ArcGIS Desktop.
  • Connect to ESRI-hosted ArcGIS On-Line (satellite imagery for the entire world, worldwide streets, terrain, boundaries and labels, political maps, and physiography).
  • Answer geographic questions and share the answers with others.
  • Perform GIS analysis (such as visibility, direction finding, and proximity search).
  • Connect to GeoRSS feeds.
  • E-mail your projects directly from the application.
  • Customise your map display (symbology, pop-up windows, layer transparency, sun shading, clouds, graticules). You can also use the free, downloadable software development kit (SDK) to create new tools and add-ons.

Connect to the online Resource Center for a one-stop place to access online help, blogs, and samples, as well as free tasks, layers, and results.

Do I need ArcGIS Server to use ArcGIS Explorer?

ArcGIS Explorer is ready to use and connects directly to ArcGIS Online, which powers the default map, basemaps, and tools you use. Though you don't need ArcGIS Server, you can extend the maps and capabilities of ArcGIS Explorer by authoring and publishing your own maps and layers via ArcGIS Server or by authoring geoprocessing tools, which can extend the ArcGIS Explorer capabilities via add-ins.

Is ArcGIS Explorer customisable?

Yes, ArcGIS Explorer can be customised in a variety of ways, many of which do not require programming. First, you can personalise the application by changing color schemes and the behavior of various aspects of the application, choosing tools to appear on the Quick Access toolbar, and changing the location of windows such as Content.

ArcGIS Explorer can be further customised using Application Configuration Manager (ACM). Using ACM, you can remove tools, add new tabs, reorganise existing tools, enable or disable capabilities (like saving the map or adding new layers), and more. These are saved as application configuration files (.ncfg), which can be opened directly via double-clicking. In many cases, ACM is used to configure ArcGIS Explorer for specific users and workflows.

Using the ArcGIS Explorer Software Developer Kit (SDK), you can extend the software's capabilities via add-ins that you create using Visual Studio. A typical example is authoring a geoprocessing tool and extending ArcGIS Explorer with additional GIS capabilities via an add-in built using the SDK. Add-ins can also be managed within application configurations.

What are application configurations?

Application configurations allow you to easily control the user experience by having centrally managed configurations that allow controlling the tools, basemaps, startup banner, and other aspects of ArcGIS Explorer.

How can I use application configurations?

Application configurations are a great way to customize ArcGIS Explorer to support specific users, tasks, or workflows. So, for example, you could create a special version of ArcGIS Explorer for planners, another for the utility department, and another for crime analysis. The application configurations can be centrally managed within an organisation.

What are some of the new file extensions associated with ArcGIS Explorer?

The latest version of ArcGIS Explorer introduces several new files. These include

  •  .nmf—A new map file containing a complete map that, when opened, opens a new map that replaces your current map
  • .nmc—A file containing new map content, which will be added to the contents of the current map 
  •  .ncfg—A new configuration file used to alter the current configuration and control various aspects of the application
  • .eaz—An ArcGIS Explorer add-in (i.e., a custom tool)

What are expansion packs?

ArcGIS Explorer expansion packs are optional downloads that are used to deliver additional ArcGIS Explorer capabilities or resources. The current list of expansion packs includes

  • Data Access Expansion Pack—Expands geodatabase functionality by allowing direct connections to multiuser geodatabases
  • Fonts Expansion Pack—Adds more ESRI fonts for use with ArcGIS Explorer when displaying ArcGIS layer files and layer packages
  • Projection Engine Expansion Pack—Adds more projections and geotransformations for use with ArcGIS Explorer

Can I use ArcGIS Explorer and ArcGIS Desktop or ArcGIS Server on the same machine?

Yes, ArcGIS Explorer can be used with other ESRI software on the same machine without any conflicts or versioning issues.

Can I work offline with ArcGIS Explorer?

ArcGIS Explorer is meant to be used in a connected environment, since the default map, basemaps, and functions are provided via ArcGIS Online, but ArcGIS Explorer will work with reduced capabilities in a disconnected (or intermittently connected) environment. You can work directly with local content or any Web-based content you've visited (and therefore cached locally), but you won't be able to use Find or other capabilities that rely on an ArcGIS Online connection.

What is the basemap gallery?

The new basemap gallery in ArcGIS Explorer allows you to choose from a variety of basemaps (including Microsoft Bing Maps content) offered through ArcGIS Online. These basemaps are the foundation on which you place other content. Basemaps can be changed on the fly without changing the order or look of other layers in your map, and the basemap you've chosen will be saved along with other content in your map.

Back to top

Can I add my own basemaps to the ArcGIS Explorer basemap gallery?

Yes, just select the content you want and choose Save As, then New Basemap. Your basemap will automatically appear in the basemap gallery.

Back to top

Can Microsoft Bing Maps be used for free in ArcGIS Explorer?

Bing Maps content is included in the new ArcGIS Explorer basemap gallery and is free for ArcGIS Desktop users and users of ArcGIS Explorer on the same machines. Stand-alone ArcGIS Explorer users who want to use Bing Maps can access it via an ArcGIS Online subscription service.

Can I symbolise data any way that I want in ArcGIS Explorer?

ArcGIS Explorer provides basic capabilities for symbolising local data and includes a rich palette of point symbols that you can extend. This release adds support for ArcGIS layer files and layer packages. Layer packages are ideal for encapsulating ArcGIS Desktop ArcMap application cartography with the data in an easy-to-share package that can be e-mailed, copied to CD or DVD, or shared via ArcGIS Online. Using layer files and layer packages, ArcGIS Desktop cartography can be viewed using ArcGIS Explorer. Basemap and map service cartography is not editable and is "as authored" by the ArcMap user who created it and published it via ArcGIS Server.

Can an ArcGIS Explorer presentation run automatically?

Yes, presentations can be set to advance automatically at a specified time interval, and the map can be saved so that the presentation starts automatically when the map is opened.

Back to top

Can you include PowerPoint slides in an ArcGIS Explorer presentation?

Yes. PowerPoint slides can be saved from PowerPoint and added to ArcGIS Explorer as an image overlay. ArcGIS Explorer presentation controls enable you to add and use multiple slides, position the slides in a variety of ways, and control when they are displayed during the presentation. Image overlays can be used to add logos, text, or other graphics that can enhance any presentation.

Does ArcGIS Explorer support projections?

Yes, ArcGIS Explorer has always projected data on the fly onto its globe. With the new option to display data in 2D mode, the map projection can be set to any ArcGIS projection and includes support for local transformations.

What languages does ArcGIS Explorer support?

Supported languages are English, German, French, Spanish, Japanese, and Chinese. Localization includes help.

I want to create an add-in and sell that as part of my business to other ArcGIS Explorer users. Is this permitted?

Yes, developers can create custom add-ins and distribute those for free or for a fee. There are no restrictions.

If I use my data with ArcGIS Explorer or use ArcGIS Online to share my data, do I give up any rights to my data to ESRI?

No, it's entirely your data, and ESRI has no rights to it.
