How do I retrieve all public geotagged photos from Flickr?

Question

I am currently creating a php app part of which involves placing geotagged photos on a Google map, I would like to be able to place all geotagged publics photos from Flickr on this map, rather than just those from a specific user. I have managed to grab some seemingly random photos using the following link:

http://api.flickr.com/services/feeds/geo/flickr.photos.search

But I want to grab all the photos available, does anyone know how I could go about doing this?

Answer 1

Check out this from the flickr API. Use 1 for public photos. You may also want to check out min_upload_date as well from the API, which allows you to display photos after the date you specify.

privacy_filter (Optional) Return photos only matching a certain privacy level. This only applies when making an authenticated call to view photos you own. Valid values are: 1 public photos 2 private photos visible to friends 3 private photos visible to family 4 private photos visible to friends & family 5 completely private photos

Answer 2

Having a very brief look through the Flickr API I would suggest you might need to do something like the following:

• request recent public photos using flickr.panda.getPhotos
• loop through and plot your photos on the map using the lat/long values returned in the results.

I don't think you will be able to request all public photos (other than maybe your own).

An example result from flickr.panda.getPhotos looks like this:

<?xml version="1.0" encoding="utf-8" ?>
