Tile Map dots too small when zoomed in #7882
Comments
I confirmed that the Tile Map request "precision" only increases every other zoom level. So that explains why the dots appear larger and smaller every other zoom level. |
Just to confirm, I can reproduce this on 5.0 as well. |
The scaling of the circle radii is based on a lot magic numbers. Also the scaling logic itself, appears somewhat ad hoc and not well-founded (cf. The scaling should likely be simplified to the following:
Regarding [a], the size of the dots bounces all over, often much too small for the corresponding geohash-cell. This issue describes one visual artifact of this. Regarding [b], the circle-radius is now proportional to the square root of the aggregate value (+ some other weighting). This seems somewhat arbitrary. |
Another related issue is the ad-hoc way that Leaflet's zoom levels are mapped to a Geohash precision level. This mapping is now manually defined in These geohash-precision-levels seem to grow much too quickly as the map's zoom level increases. While geohash-precision levels do not map to Leaflet zoom-levels one-to-one (former subdivides with base 8, the latter with base 2), here too it may help to introduce some rigidity for a more predictable user experience. For example, a geohash-grid may not be smaller than some number of pixels. |
see also this user's screenshots, who has a similar issue with his data (geohash too precise for zoom level). |
closed with #8000. |

Description of the problem including expected versus actual behavior: We just added ability to zoom to level 10 in this release. But during testing, when zoomed all the way in, the dots seem too small. But maybe I just don't understand how the precision scales with the map levels.
