GeoDE: Crowd-sourcing details

Crowdsourcing GeoDE

We ask participants from 6 different regions of the world to send us images of 40 different objects. This results ins a dataset comprising of 61,940 images roughly balanced across both these objects and regions.Instructions given to the workers is shown in the following image.

General Instructions
In this task, you will submit up to 3 photos of the same type of object (e.g., upload 3 photos of 3 different bags; please do not upload 3 photos of the same bag from different angles).
1. Please make sure the location function is enabled for the camera.
2. The photo resolution should be at least 640 x 480.
3. All images should be new photos captured with Appen Mobile.
4. Please make sure it’s a single object per image.
5. Please make sure it’s a well-lit environment and the object is clearly visible in the photos.
