GPS Mapping Software - Projecting Waypoints - Tutorial

Introduction

A Waypoint can be defined as a marked position on a map, somewhere on the earth, with known coordinates. A Waypoint can be part of a route. In GPS receivers, a Waypoint is a point that can be selected as a coordinate to navigate to, or it can be used to just display a symbol on a map.

Projecting a Waypoint

When projecting a Waypoint, you basically create a Waypoint on a certain distance and heading from a known position. In GPS Mapping Studio, there are multiple ways to project a waypoint. You can project the waypoint from another Waypoint, a position on the map, a manually entered position or the current GPS position. In this tutorial, we will project a Waypoint, using another Waypoint as a reference.

To open the "Project Waypoint" window, select the "Tools" => "Project Waypoint" option from the menu. The following window will appear:

In this window, you will find 2 buttons, a "Select..." button, to select the source Waypoint, and a "GPS" button which can be used to automatically enter the current GPS position as source location. For this example, we will use another waypoint, so we click the "Select..." button and choose a Waypoint from the list. If there is no Waypoint in the list, you can walk through the Creating Waypoints tutorial to create a one. Once you selected a Waypoint, the coordinates of this Waypoint are copied into the Latitude / Longitude fields.

For this example, we will create a new Waypoint at 100 meters (0.100 kilometers) and a 45 degrees course from the selected Waypoint. After we entered these values, we click "Project...".

Saving the Waypoint

A "Waypoint Properties" window will appear with the location of the projected Waypoint already entered. You can now modify the Waypoint's attributes such as name and symbol. Please note, that when a new Waypoint is created, by default the symbol and label properties are copied from the last created waypoint. This might be very handy when creating multiple waypoints that should use the same attributes. When done, click "OK" to save the waypoint.

Ready !

When looking at the map, you will find the "WPT002" waypoint projected at an angle of 45 degrees and a distance of 100 meter from the selected waypoint.
