FAQ xLocate 2

Postby Bernd Welter » Mon Apr 08, 2019 11:42 am

Hi there,

in the context of xLocate 2 some questions occur periodically. I therefore started to collect them. The following list is subject to grow ;-)

  • We heard that the geocoding within xLocate 2 requires data beyond the traditional map. Does this mean we can't use xServer 2 without the geocoder data? - It is no problem to use xServer 2 without the geocoder data (folder GCD below the basemap) as long as you deactivate the xLocate module.
  • How much disk space do we have to provide for this GCD data? - The geocoding index is really hungry. For the 2019.2H Europe data you have to provide about 50 GB of data (in addition to the basemap). The US map 2019 index requires about 40 GB.
  • What about the coverage of the geocoding data? - The current index (april 2019) covers most of the western European countries with almost 100%. In countries of Eastern Europe the data is a bit lower. In UK the data is compareably poor.
  • Does xLocate 2 support data of both major providers? - Currently (april 2019) we can offer HERE data for Europe and the US.
  • Does xLocate 2 support to return a list of house numbers within a street? I've seen some screenshots... - We know these screenshots. They have been created with internal tools and the purpose is to show the quality of the data. The interface of Locate 2 does not return such lists: if your input is rough we return reference points of upperlying streets instead.
  • Is there a list of parameters we can use to parametrize the geocoding? - The design of xLocate2 is based on "reduce parameters": operations such as "limit the maximum number of hits" is therefore shifted to the client logic ;-)
Let me know if you have further questions that could be helpful.
