As well as the start and end points (Locations), MileCharter has a number of options that control the routing and reported data. These are in the Route Calculation Options box in the lower left:




In addition to the Route Calculation Options, there are the Output Options (top right), and the Shortest/Quickest Route Options (mid-right). All of these option settings are saved and will be used as defaults for the next time that you use MileCharter.



Route Calculation Options


The Output check boxes define the kind of data that will be created. The default is Distances, and this will create a traditional mileage chart. You may also output Travel Times, and/or Costs. Each output type will be saved to an individual worksheet in the same Excel workbook, or a separate text file. At least one of these three check boxes must be selected – i.e. you must tell MileCharter to calculate at least one output value.


Costs are calculated using a rate table. This uses the same mechanism as MileCharter for MapPoint's "Costs via Rate Table" option, and is discussed further on the Setting Road Costs and Types of Rate Table pages.


The chart's distance units are specified using the Distance Units drop-down box. These are typically miles or kilometers. The Time Units can be set to Hours:Minutes, Hours, or Minutes. The Hours:Minutes option will format the travel times in the form of "hours:minutes:seconds" (hh:mm:ss), whilst the remaining options will report decimal time (e.g. 1hr 30mins is 1.5 decimal hours).


The Find option lets you choose the type of route to find. Because the road pack will have already been optimized to find either the fastest routes or the shortest routes, only one of these will be visible. In addition to the route calculation (fastest or shortest), there is the option to calculate Straight Line distances. Straight Line finds the "as the crow flies" straight line distance between two points. Technically, this is defined as the Great Circle distance. Note that the Straight Line option can not be used to calculate travel times or cost estimates.


'Square' mileage charts with matching source and destination data views (or selection sets) may result in duplicate route calculations. These are controlled by the Duplicates setting which is covered on the Duplicate Routes page.
