Altitude data is available in principle from the GPS (although the precission is worse for this). So it would be possible to implement support for altitude too if that is needed.
Do you have more information about what exactly you would like to achieve?
- cryptoz 8y agoI was just imagining it would be neat to find 3D areas: go upstairs, down a hall, downstairs, and have it compute the volume of the 3D area. The barometers available on devices would allow this to happen, but I don't know (don't think) that when you request location access via the browser it returns altitude information if the device supports it.
- dafer45 8y agoI see. This is indeed harder. I don't think there is any web API for accessing these sensors. Moreover, measuring the volume would require tracing out a much more complicated path since volumes are bounded by surfaces rather than edges. Given that the technical problems were solved, do you think that a human actually could manage to trace out a volume in an other cases than simple rectangular blocks etc?
