These settings are for the World Origin. In Surveyor, they are located from the Menu under Edit Environment. The World Origin is a point on your Route, usually the North West corner of the first baseboard that was auto placed when the Route was created. If you click on the magnifying glass icon or 'Go to world origin'. It will move your view to where the World Origin is on the map.
You can add a World Origin marker object, but it's function is unknown, and will actually hide your maps real World Origin. We do not advise adding one. If you already placed a World Origin object on your map, you can remove it using the Objects F3 Delete Object D tool.
Once you have found the true world-origin point, you can use the calculators above to create the Latitude, Longitude and Altitude World Origin code snippet for your config.txt file. After you edit and submit the changes, when you return to Surveyor, the base elevation will be set to wherever the World Origin object is. All assets on the map will be relative to the base elevation, so it will appear as nothing has changed, but you can see what it did by clicking on the Topology F1 tab and then on Get Height. Your new altitude should show in the Height Value text box.
The last icon is a wrench or 'Get world origin'. DO NOT USE. Our tests have shown that certain combinations of actions can result in your Route becoming corrupted, previously set altitude reset to zero and coordinates set back to some sort of game preset. Use our tools above and edit your config.txt file instead, and you will not have to deal with the broken interface.
The easiest way to get a set of coordinates at the city level, is to do a Google search for ' LAT LONG city name '. To get an exact Geo location of a landmark for example, you may need to use a mapping site like gps-coordinates.net. Once you have your latitude and longitude, the calculators will automatically match the coordinates and return the current elevation if you did not input an elevation manually.
