Instead, it was engineered for convenience in working with cached map tiles. The modified Mercator projection used by Google, Bing, and ArcGIS Online is not designed to minimize distortion at all. Other projections (such as UTM and State Plane) are designed for focused areas of the globe in order to keep the distortion minimal. Some projections such as Robinson or Winkel Tripel attempt to minimize distortion across the world through some compromise of all those factors. Why is the Google/Bing/ArcGIS Online projection not acceptable for measurements?Įvery map projection causes distortion of shapes, areas, directions, and/or distances. You should instead re-project user-submitted geometries into a more appropriate coordinate system before you perform a measurement. If you use the new ArcGIS Online services, avoid the temptation to perform measurements of polylines and polygons in Web Mercator. Lines are displayed as Geodesic when edit mode is offīug fix : Upload Coordinates should now work.Recently, ArcGIS Online services became available in the same “Web Mercator” projection used by Google Maps and Bing Maps. New option : Edit Squares can be togged On/OffĮdit Squares are Off when the map first loads but can still be toggled on Replaced with custom search toolīug Fix : Clicking on an existing marker to add to the route did not work and also caused the tool to stop functioningīug Fix : Autopan did not work initially until swicthed off and on. Location displayed when you hover over a marker now has fewer decimal places The marker will display the distance up to that leg on the route when you hover over it You can also delete a marker by right clicking on the dot below the markerĪdded yards units of distance measurement Its now possible add a marker to the route midway along the route. Implemented a mouseover event so when you hover over the elevation chart, a marker on the map highlights the location

New option added to show the elevation of your route on a bar chart New option added to allow you to share your distance calculator route on Twitter, Facebook or email Removed Google Local Search API (Deprecated) Now zooms in to find the locationįixed issue where a marker that had been repositioned retained its original lat/lng in the text that appears during hover over If you perform an unattached search (not a distance marker), the search result marker can be easily removed from the map by clicking on that marker Now pre-selects text after a search is complete to allow rapid input of multiple locations Now allows enter/return to be hit to cause the search. Now adds a distance marker upon finding a result unless the user opt's out of this Uses new cookie so any previous systems/settings on your machine will be erased! sorry! Google Search bar at bottom left is not yet available. Implemented Google Maps Javascript API V3 More settings are now saved such as toggle markers, Google Search and Map Type

Google Search can now be enabled by a check box Map saves last position for when you next visitĪdded Marker tooltip showing marker id and lat/lng Removed Print Option (Ctrl+Print Screen works better) Great Circle display and distance calculation If you ever need to start from scratch then use the button. The map will also automatically save your route in your temporary internet cookies so that you can return and see the route as you last left it. Then the main problem is converting the Google Map unit to miles and kilometers. Calculating the 'As the Crow Flies' distance is a matter of using Great Circle formula.

Click to get a chart showing the elevation of your routeĬlearly you, the user inputs two 'points' that are used to calculate the distance.

You can choose between miles and kilometers (km) for the Total Distance readout.

Use the Quick Find text box to quickly relocate the map.

Click to erase all markers and start again.

Click to zoom the map around all markers.

You can move the markers after they have been positioned so you can modify you route on the fly and see how the distance will be affected. All distances are estimations so Daft Logic does not accept any responsibility that may arise when the value reported is incorrect.
