Geocode HIT

The purpose of the HIT is to help match a databases of address to exact GPS coordinates. These coordinates will then be used by a mobile application to help people see what venues are nearby.

Unfortunately, both the input addresses and existing databases are not perfect. Simple addresses can be automatically geocoded with a high degree of accuracy. Many addresses are relative locations, or are inside mall's and shopping centres.

Example: <geshi> Siggi's at the Port Office Cnr Edward and Margaret Streets Brisbane QLD 4000 Australia 07 3221 1999 </geshi>

In Australia, 'Cnr' is used to abbreviate corner. So, one is looking for an address whose pin is at the corner of Edward and Margaret Streets. The choices are:

(A) Brisbane QLD 4000 Australia

(B) Brisbane QLD 4000 Australia

(C) None of the locations are very close.

In the above example, the correct choice is A, because the pin is on the corner, and it is clearly in Brisbane.

Hints:

  • If the image isn't big enough, it's hyperlinked to a full map. Click and the image, and zoom in/out as needed.
  • The cities don't have to match, and are often wrong. Often one location will list a suburb, while the other will list the greater municipality which is it part of. Learning a bit about the geography of the hit improves your accuracy.
  • For shopping malls, try to find something which looks like a mall, and has a matching city.
  • Often you can Google, and find the venue's website. On the website they usually have a map. Find the image which matches their map.

If you see this image:

it means you've done your limit of hits for the day. Google limits the number of maps a single person can request. Wait until tomorrow, and there may be some more hits for you.
