Hints and tips
Geocoding is finding an address [[File:20151124 Wiki - Add all destinations.png|thumb|Addresses are found on the map. ]] To plan a route, we need the geographical position of each positions of your destinationsare required. All your addresses therefore need to be translated to map coordinates. Finding an address on the map is called ''Geocoding''.
== How we geocode ==
While it should be obvious that each address corresponds with only one position on the planet, in real life it's not that easy. Addresses may be wrong, wrongly spelled, not complete, or not recognized at all, i.e. when they are new or renamed. That makes geocoding a difficult task, one that other services have specialized in.
RouteXL makes use sends your addresses to one of these awesome third-party geocoding services: Bing, Google, hereHere, Mapbox, Mapquest, Nominatim or Photon. You can select your preferred geocoder in the [[options]]. There is no good or bad, each geocoder has it's its own strengths and weaknesses. Their performance may vary in various regions and with various [[address format]] styles. == Hints and tips == To improve geocoding, the first thing you should check is your input. If your addresses are not correct or not complete, finding them on the map will be problematic. Addresses may show up in the wrong place or not at all. Make sure you use the preferred [[address format]]. Remove any text that is not part of the address, like customer names or notes. If you still need that text, import it as [[import|additional fields]]. If your addresses are correct and complete, you can change these settings in [[Options]] > Geocoding to further improve the results: * Change the '''preferred geocoder'''. Some of the geocoders may set usage limits, as they often offer it as a free service. Selecting another geocoding service may impact address finding drastically. * Fill out an '''address suffix'''. E.g. if your addresses have no country, add it as suffix. If all your addresses are in the United States, but that is not in the addresses, fill out "United States" (without the quotes). The suffix will be added to all addresses automatically before sending them to the geocoding service. * Change the '''search area'''. If all your addresses are in a small area, such as a village, select a (S)mall or (M)edium search area to skip addresses that are too far away. The map center is used as center of the search area, so move it to the right spot before you start adding addresses. * Enable '''precise address''' checking. You'll get a warning if an address did not provide a exact position, but an approximate, i.e. zip code area. ''Hint: if you have an account and are logged in, the options will be saved. Without an account, or when not logged in, your changes will be lost after each session.''
=== Location based ===
If you're in Europe you are probably not interested in addresses in the USA, unless you plan a holiday road trip. RouteXL filters some geocoding results on distance based on your location and some . Some geocoders also use your location to bias the search results. Your location is determined by the [[User interface|map center]].
''Hint: if addresses are way off, move the map towards the approximate location.''
== Change settings = Testing ===
To improve If you have changed the geocodingoptions, you can change these test your settings in using the [[OptionsSearch|search box]]. Fill out an address, or a part of it, and wait a few seconds. The search box autocompletion function will display a list of alternative addresses. If these do not appear, or the alternatives are wrong, try other settings for geocoding.
* Select another preferred geocoder from the dropdown list.=== Premium ===
* Fill out an address suffixIf you need the best geocoding service, e[[upgrades|upgrade]] to one of our premium subscriptions.g. your country if you have addresses without country.

=== Testing ===The UN estimates that 4 billion people lack a reliable way to address their homes. Poor addressing means deliveries go astray, businesses can’t be found, aid doesn’t get through, remote assets are difficult to manage and friends fail to meet up. [https://what3words.com/ What3words] gives everyone and everywhere a 3 word address. It’s precise, simple and unique. And it’s changing the way people and businesses talk about location.
If you selected another geocoding service RouteXL supports What3words addressing. You can enter the address in the search field or added a suffix, you can test your settings using use the [[Search|search boxImport]]button. Fill out an When a 3 word addressis detected, or a part of itthe What3words system is called to find its geographic coordinates. Next to that, and wait a few seconds. The search box autocompletion function will display a list of alternative your locations can be translated to 3 word addresses. If these do not appear, or To activate the What3words integration use the setting in the alternatives are wrong, try other settings for geocoding[[Options]].
