open /map page more zoomed in for performance reasons

[jywarren]

Really big views are a performance issue for displaying nearby people, so we should try to zoom in a bit on https://publiclab.org/map

Code is here:

plots2/app/controllers/map_controller.rb

Line 32 in ba94709

@zoom = current_user.get_value_of_power_tag("zoom").to_f if current_user&.has_power_tag("zoom")

And is used here in the template:

plots2/app/views/map/map.html.erb

Lines 43 to 45 in ba94709

	<% if @zoom %>
	urlHash.setUrlHashParameter('zoom', <%= @zoom %> + "");
	<% end %>

If there is no zoom profile tag, it seems to default to a global view!

https://publiclab.org/map#3/40.99999999999999/-52.89453124999999

Let's not do that. Maybe choose like zoom 10 as default?

https://publiclab.org/map#10/41.88165276651511/-71.36132687330247

https://publiclab.org/map#11/40.67759191045513/-73.8769419793971 zoom 10 or 11 seems to be good. here's someone.

@jywarren I don't do ruby, but I think I can take a shot at this!
And perhaps ask a question if I get stuck.

Thanks!!

Hi @jywarren @cesswairimu please do help.😊

I'm trying to get exactly what we need to do here. Is it to change the global view here

plots2/app/controllers/map_controller.rb

Line 26 in ba94709

@zoom = 3

from 3 to 10 or 11, or to define another default value of say 11 while still leaving 3 as the global view?

Thank you!

[cesswairimu]

@Shulammite-Aso you could try different zooms see which one gives the best display and use that as the default...10 was the proposed one

Thanks @cesswairimu
This will mean simply removing 3 and replacing with 10 right?
Just trying to know if there's any other code adjustment I'd need to make before this works.

[cesswairimu]

yeah just the zoom I believe. Thanks

Amazing @Shulammite-Aso thank you! Reviewing now!
