Process Purpose

The Calculate Distance process is used to calculate the distance between two points, specifically, two GPS coordinates (a start latitude/longitude coordinate and an end latitude/longitude coordinate).

When you add a process, you are required to define its settings. This occurs in the process's properties window which is displayed automatically after having added the Calculate Distance process.

If any subsequent edition is required, double-click the process to open its properties window and enter the necessary modifications.

Fill in the following options:

Start
Latitude	Insert the starting latitude value or click and select a variable with that value. See Variable Definition.
Longitude	Insert the starting longitude value or click and select a variable with that value.
Stop
Latitude	Insert the end latitude value or click and select a variable with that value.
Longitude	Insert the end longitude value or click and select a variable with that value.
Store Result into Variable
Variable	Click to select the variable that will receive the calculation's result value.

When defining the latitude/longitude values, consider the hint information in each box.

If required, click to attach any relevant notes to this process. Click it and enter your notes in the resulting text box. These notes will be displayed in the corresponding "Actions" tab or "Process" window (in the "Notes" field) and in the "Developer Report".

After filling in the required options, click to conclude or to abort the operation.

The added process is displayed in the corresponding "Actions" tab or "Process" window.

Use the right click in MCL-Designer's input boxes to access certain features regarding the input box's option as well as general actions such as "Copy"; "Paste"; "Search".

Ex: If you right-click the "Variable" input box (included in a "Conversion's" properties window), you are provided with the "Search..."and "Variable Select" options.

If you right-click another input box, it will provide other possibilities.
