Avast Ye Matey! If you're looking bad data, then you need look no further than Null Island! Located in the Gulf of Guinea off the coast of Africa, Null Island is a mystical place, where incorrectly geo-coded entities magically float in water.

Firing up an app that uses a map-based search function? Want to find the bad data in the app? Then simply head to the geo-coordinates of 0.0.0.0. Looking to see bad data across multiple platforms? You'll find all this and more, off the coast of Africa.

As i've reported before, you can do this with a whole lot of apps.

Today I spotted it with Grabbd.

Take a look at some of the spots that are floating off the coast of Africa:

London restaurants floating off the coast of Africa.

Looking for yer roast beef sandwich, ye scirvy dog? It's floating out in the ocean. 2nd start to the right, and straight on till dawn!






Steps to Reproduce:

1. Download and launch the Grabbd app for iOS
2. Move the map and search 0.0.0.0

Result: There's always bad data at 0.0.0.0

Expected: There should not be bad data at 0.0.0.0

OpenTable app for iOS: Bad Data in the Gulf of Guinea!

iOS 13.3.1
OpenTable app for iOS (version 13.12.2)

Description:

Have ever been curious to know a quick way to find "bad data" in an app? Meaning, data that may have a listed address, but one that isn't recognized as valid? Have you every wanted to see if the particular map-integrated app you're using has entities which aren't geo-locating to the correct place?

Here's an easy way to do it!

The OpenTable app has a problem which is common on numerous other apps. Here's a summation of the problem: if a restaurant address is listed that is not recognized as a "valid" it is deposited at a latitude/longitude of "0.0.0.0."

This "0.0.0.0" is off the coast of Africa and is known as a mythical "Null Island" for database purposes. 

Some of the various locations you can quickly find - many of them are in Australia...
The Mexican Port Douglas
Lime Leaf Thai Restaurant 
Choo Choos Marina Port Douglas

Steps to Reproduce:

1. Download and launch the OpenTable app for iOS (version 13.12.2)
2. Sign into an account
3. Click on "Search" - search in any location
4. Click on the Map
5. Search in the Gulf of Guinea area off of West Africa
OR:
6. Run a search for restaurants in the Gulf of Guinea

Result: Searching the 0.0.0.0 area in many apps will show you locations that lack a correct address

Expected: Not sure - just a fun way to find bad data across multiple apps!
