Give users an indication of the data resolution / accuracy to expect

[j08lue]

The apps lets users explore temperatures (and in the future other parameters) for a point location.

In reality, the data we currently host is on a 0.25x0.25 degree regular global grid (resolution >=28 km), so temperatures will for example not account for urban heat island effects or effects of local topography.

Can we help users somehow understand these limitations? Do we need to?

Explain limitations

As a first-off, we added a technical explanation to the parameter description in

• Update data layer modal with GDDP description #44

Show with marker

Other considerations were to make the marker indicate the actual scale of data

Show grid

or to add a grid overlay e.g. as grid_lines.json and snap to grid cell centers or so - we are exploring that here:

• [DO NOT MERGE] Experiment with grid and snap-to-grid for the buffer #45

Restrict zoom

Another approach to manager the users' expectations would be to restrict the zoom. At least for temporally aggregated temperature, the data does not vary a lot on a grid cell scale anyways and the interpolation for the video at mobile quality blurs the data further.
