THINGS TO CONSIDER BEFORE GEOCODING

Things to considerFirst and foremost, you should understand your data and check it for accuracy and completeness prior to geocoding.

Below are some initial factors to consider:

  • What is the appropriate geographic level you hoping to achieve: address point, house number range, street center, Post (zip) code or city?
  • Which coordinate system and projection are you using or will be using?
  • Is your data going to be linked to other data (e.g. demographics)?
  • Which countries or countries are your addresses in?
  • What kind of addresses do you have (street address, road intersection, building name, direction from a landmark)?
  • When was the address or location information collected and are they current?
  • What is the address (residence or PO Box)?
  • PO Boxes cannot be geocoded!
  • Make sure the addresses in your database have complete and accurate information (number, street, direction, city, post (zip) code).
  • Clean your data – have address elements in appropriate fields (number and street, city, state, post (zip) code)
  • And most importantly make sure you comply to all data privacy regulations.
