====== System Units ======

By default OFM assumes all mapping data is measured in meters.

You can customize how OFM describes the system unit and multitudes of it by using the following tag in the [[configuration_ui]] file.

===== UnitDescription Tag =====

The ''UnitDescription'' tag describes how OFM describes map units.  You can follow the example and provide a name and abbreviation for the system units and add a number of Sub-units.  

Example (default : assumes 1 system unit == 1 meter)
<code xml>
   <UnitDescription>
     <System>
       <Abbr>m</Abbr>
       <Name>meters</Name>
     </System>
     <SubUnit>
       <SysUnits>1000</SysUnits>
       <Abbr>km</Abbr>
       <Name>kilometers</Name>
     </SubUnit>
   </UnitDescription>
</code>

Example2 (assumes 1 system unit == 1 foot)
<code xml>
   <UnitDescription>
     <System>
       <Abbr>ft</Abbr>
       <Name>foot</Name>
     </System>
     <SubUnit>
       <SysUnits>3</SysUnits>
       <Abbr>yd</Abbr>
       <Name>yard</Name>
     </SubUnit>
     <SubUnit>
       <SysUnits>5280</SysUnits>
       <Abbr>mi</Abbr>
       <Name>mile</Name>
     </SubUnit>
   </UnitDescription>
