Geocoding is the process of converting a text-based location (e.g. a store locator address) into geographic co-ordinates which can be shown on a map. Blipstar uses one of the best one available but even that can sometimes fail to geocode something, or geocode it in the wrong location. In these instances you typically need to reformat the address into something the geocoder does recognize or manually define the geographic co-ordinates. Sometimes a simple thing such as adding or removing a comma can be the difference between a location geocoding or not.
|1.||Essentially the easiest type of text to geocode follows the structure of an address you'd put on a letter or parcel.|
|2.||Double check the spelling and ensure the zip/postal code is correct.|
|3.||Make sure the address is as complete as possible including a zip code/postal code.|
|4.||Use the street number of a building rather than building name if possible.|
|5.||Do not specify address elements such as business names, unit, floor or suite numbers that aren't included in the official postal address.|
|6.||Specify a country in the Country field - this provides an extra clue to the geocoder and resolves ambiguity.|
|7.||Be sure to verify the locations once geocoding is complete. The Geocoder might have misinterpreted the address (so although the location geocoded it's not where it should be).|
If all else fails you can specify geographic co-ordinates yourself by having a field in the spreadsheet called "Position" and entering a WGS84 lat,long co-ordinate. For example the position of Big Ben in London is '51.500611,0.124611'.
How to edit addressesYou can either:
- use the Edit function (accessed from the Upload/Edit page) to edit the address within Blipstar
- update the addresses in your spreadsheet and re-upload
