POI filtering

[kerryconvery]

Hi

Is it possible to get, from the API, a list of POIs within a given radius, say 1 or 2 meters, from where the user is standing? Or will I just need to download all of the POI locations and then have my own algorithm work this out?

Also does the API give the users orientation, i.e. which way they are facing? as I'd like to select POIs within 180 degrees instead of 360?

That's an interesting concept. At the moment the API serves all POIs per building or all POIs per floor. However, we could definetely utilize Couchbase's geospatial capabilities to serve all POIs that are positioned within a spexific bounding box.

Regarding the orientation, this is something the Android app has access to through the device's sensors therefore it should be possible to filter POIs based on a given position and angle.

At the moment there are no such functionalities in place since most of our use cases have a number of POIs that can be easily loaded without any filtering.

Approximately how many POIs do you have in your use case - if you don't mind me asking?

For the time being you should handle the filtering at the front-end level until the functionalities you mentioned are built into the server - it's definetely something we will be looking into.

This is indeed an easy and timely addition. It's already offered for radio map requests. We should discuss it internally to offer this endpoint as well.

For our hack day project probably around 20 POIs since we want to keep it small. Depending on the efficiency of the algorithm shouldn't adversely impact performance. At a later date, should we decide to take the project to production level, then we are probably looking several 100 or possibly even a 1000+ POIs but that is a way off and we can review our options then.

Dimitri, please kindly include the above endpoint (similar to the new radiomap endpoints) in your next release.
