Scroll Prev Top Next More

As well as the start and end points (Locations), MileCharter has a number of options that can be set:




The main options are divided into two sections: Route Calculation Options, and Output Options. The Shortest/Quickest Route and Conditional Output options are only available with the Professional license, and are discussed in the Reporting only the Quickest or Closest Destinations and Conditional Output sections respectively.


Your option settings will be saved and used as defaults for the next time that you use MileCharter.



Route Calculation Options


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


Travel Times are calculated using the road speeds that can be set by pressing the Speeds button. Note that these road speeds do not influence Maptitude's route finding. They only influence the final calculated travel time.


Costs can be calculated using a list of per-distance costs for each road type, or using a rate table. The rate table option uses the same mechanism as MileCharter for MapPoint's "Costs via Rate Table" option. These options are discussed further on the Setting Road Costs and Rate Table Properties pages.


Road speed and cost parameters can also be set using the Roads button to display the Road Parameters dialog box. This dialog box can also be used to save or load the various road parameters.


The chart's distance units are the same as Maptitude's current distance units. These are displayed in the Distance Units box. 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. The most common route options are the Fastest and the Shortest route options. 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.


Conditional logic can also be applied to determine if a route should be applied. This is described on the Conditional Output page.
