Distance Calculators: How They Work and How to Use Them Distance calculators are tools for calculating the distance in between two or more points on the map. You can change distance unit – miles, meters or kilometers – as you prefer. Usually, you can just type in the names of the places whose distance from each other you’d like to know, and then click some button to show results. Postcodes and addresses may be used as well. How Distance Calculators Work After you click the search button, a search will start to locate the place you indicated. First off, a search will be made on an internal list of usual locations. If you get no match, the search will now be made with the use of Google Maps API GlocalSearch. If also unsuccessful, you will be asked to pinpoint the location of the place by clicking on the map. This will allow you determine the distance between the two points, and the location will be saved in the internal database so that it can be located when someone searches for it in the future.

When a result has been returned, you can save the URL and use it for your own reference, or to give it to a friend or family member who may also need it.
Calculators – Getting Started & Next Steps
How Distance Is Determined The distance that lies between any two features is determined as the shortest distance between them, that is, in which the two features are nearest each other. This logic is used by any geoprocessing tool that calculates distance. Input data in an equidistance projected coordinate system lead to the most accurate distance measurements. Though distance calculations can be done anytime regardless of coordinate system, the results may lack accuracy or may even be meaningless when the data is in a geographic coordinate system or an incorrectly chosen projected coordinate system. Important Considerations Several features can be equally closest to another feature. When this happens, one of the equally closest features is arbitrarily picked as the closest. A feature that contains or is contained another feature has a distance of zero. A distance of zero is calculated in a scenario where there is at least one x,y coordinate shared between them. Therefore, when two features cross, intersect, touch or overlap, the distance is zero. Distance is always based on the a polygon feature’s outer edges instead of the center. As we mentioned, zero is the distance between any feature and the polygon surrounding it. The distance between any two features remains the same regardless of the one being measured to and from. Basic Distance-finding Operations Measuring distance depends on the geometry type of the features, as well as other factors like the coordinate system. However, three basic rules dictate how distance will be calculated. First, the distance between two points is the straight line that connects the points. Second, distance from one point to one line can be the perpendicular vertex or the closest vertex. Third and last, segment vertices determine the distance between polylines.
