ArcTools
  	ArcMap has a large number of individual tools and provides a great deal of functionality. Unfortunately, the GIS world is huge and there are many specific interests. One software package cannot possibility offer all the tools required. 
  	Below is a summary of the features of ArcMap that may help you decide how it fits within your "Toolbox".
  	Data Support
    
      - TINS: Triangulated Irregular Network. Important for hydrologic modeling and 3D rendering 
- Vector: Point, Polyline, Polygons
- Topological: Through GeoDatabase (networks as well)
- Raster (limited for floating point and n-band)
Data Creation and Management
  	
  	  - File Conversion (limited, see FWTools)
- Digitizing
- Geocoding
- Defining and transforming SRSes (non-standard)
- Data Type Conversion: Limited  	
Analysis
  	
  	  - 3D Operations (minimal)
- Utility Networks (2d)
- Interpolation: IDW, Splines, Kriging (one version with bins)
- Image Classification: Limited
- Network Analysis
- Topography: line of sight
- Surface: Slope, aspect, view sheds
- Raster 
  	    
  	      - Math
- Density
- Hydrology: Limited
- Overlay
- Neighborhood (zones) stats and operations
 
- Vector 
  	    
  	      - Overlays  	        
- Distance measures
- Stats
 
Visualization
  	
  	  - Final maps (moderate quality)  	
- 3D Visualization
- Limited animation
ArcGIS Pro (ArcPro) 
  	Esri has announcded that ArcGIS Pro will eventually replace ArcMap. Key changes include:
  	
      - True support for 64-bit?
- New GUI (similar to Office 365)
  	    
            - Data view is now "Map"
- Layout view is "Layout"
- There is a "Project" tab
- Favorites for Tools!
 
- Have to join ArcGIS Online to use it 
ArcGIS Online (ArcOnline) 
  	
      - Esri's web system. 
- Story maps
- Online interactive maps
- Data storage that can be shared with other ArcGIS users
