Location Converter and Distance Calculator

The Location Converter and Distance Calculator tools are accessed from the main menu.

Location Converter

Location converter is used to convert a map location to different coordinate systems.

A map point must first be placed on the map, using either by clicking the mouse on the map itself, or by entering the information in the input box on the left. Once a location is mapped, the boxes on the left show the location expressed in different coordinate systems.

The map point can be moved on the map using the mouse, and the results fields will update.

Distance Calculator

Distance calculator is used to calculate the distance between any two map points (within Colorado only).

The first map point A is placed on the map either by clicking on the map, or by entering the coordinates in the left panel. One of eight coordinate systems can be chosen using the dropdown. After point A is placed, point B can be placed on the map.

The distance between the points will be calculated, and displayed on the map. Either point can be moved on the map using the mouse. If the coordinate system is changed for either point, that point will be removed and a new point will need to be placed before it is re-calculated and displayed.
