Choosing symbols
ArcGIS has
thousands of symbols for common map features that you can use. The symbols are
organized into more than 25 symbol sets. You can also import additional symbol
sets or create your own symbols.
Some
symbol sets are general-purpose, like the ESRI symbol set. Others have
specialized symbols that reflect the needs or standards of different
industries, such as municipal, conservation, geology, crime analysis, and real
estate.
Here are just a few of the point (marker) symbols that come with ArcGIS. These are from the ESRI, Crime Analysis, Utilities, and Forestry symbol sets (clockwise from upper left).
Be sure to
explore these specialized symbol sets when you're looking for a particular
symbol. Often, several of them will contain similar symbols, and with a little
searching you'll probably find what you need.
Both the Environmental and Crime symbol sets contain symbols that you might use to represent shipwrecks.
