For many of the visits, you will see an overlapping requirement in the instructions. This page will show you:
What is Overlap
Overlap simply means that your previously captured photo and your next photo capture share a row or column of the same products.
How much Overlap do I need?
Your photos need to overlap anywhere from 15-60%. We know it can be a little challenging to put percentages on images when you're in a store, so a good rule of thumb is to overlap 1-3 columns of products for side-by-side photos (depending on how big the products are), and to always overlap one full shelf if you're taking a top and bottom photo.
Additional considerations: For an overlap to be effective, it also needs to be taken from the same angle and the same distance from the shelf, otherwise, the images cannot be put together. Notice in the examples below how the four photos all have either a row or a column of the same product, and are taken from the same angle and distance from the shelf.
Example 1 - Overlapping columns
Example 2 - Overlapping rows
Why it Matters
We use your photos to put together an image of the full aisle, category, or display being captured. We do this by putting all your photos together where they overlap so we can show the client the full view of the aisle/category/display. Here are examples of multiple images being put together to produce a full view.

What to Avoid
You should always have overlap in your images. Avoid skipping any part of the shelf, whether due to obstacles or otherwise. When you skip part of the shelf, or when your overlap is insufficient, we cannot put your images together. As a result, we cannot use the images you submitted to obtain data, and we're unable to approve the visit. Here is an example of a shelf where the overlap was missed and therefore was not usable.
Example - Missed Overlap
When an overlap is missing, like it is above, we have no way of knowing how much of the aisle/category/display was missed, so we have to reject the entire visit.
