Render more details in lower zoom LoMaps levels

This is not good solution. I don't want to switch maps when I'm planning trips - especially when I'm using native maps and themes.

I usually use higher zoom levels to find a cities/areas when I'm completely offline or without data (in moutains with no gsm or when I want to avoid roaming - ie. 1MB/10€ in Switzerland). Big flat green with nothing else doesn't help :-)

World base map works in different way. It turns on automatically when you zoom-out to level < 9.

Perhaps a switch for dense and sparse areas, for the latter to display roads sooner ?

Like a road analogy for Elevate/Elements OAM theme for dense and sparse outdoor ?

As one size fits all very seldom.

Making themes is a trade-off work manoeuvring between 2 extremes:

- to have it crystal clear and legendless, display little and being useless by swallowing most of useful information.

- to have it rich, display much and being useless by confusing with information flood and big legend need.

I understand focusing ROAD theme on roads themselves and I agree with minamalistic approach. OTOH, for roads themselves, it should provide relevant useful information and avoid oversimplification.

Existence and class of road are relevant useful information. Too few roads is as bad as too many.

Germany definitely needs something different than Arizona or Australia.

I like in this context idea of Waymark theme.

It has for road&city scenario a switch "way road low zoom", affecting zoom level when minor roads/way start to accur ).

If implemented to internal Road them, if could be named like "Sparse roads" and could shift zoom levels 1-2 levels down.

Sorry this isn't really my cup of tea. I can not imagine some option in themes that would change the visibility of line elements. And about minimalism - see the attached screenshot. It's from waze probably the most trendy navigation app. I do not want to create waze app but you can see that also minimalism can work :)

If minimalism leads to empty map of big area, I do not think it works.. :-) It is useful to see the road context that the route follows.

That's ins't such bad idea. But the question is how define the borders (area) for computing of the trashold. It cann't be map tile because touching tiles can have different densisty. Maybe some pre-processing during map generation. We could compute for example total lenght of secondaries for whole country. Compare lenght with country area and based on that defines some logic. But what about mentioned Australia, where is 95% country is empty and all population (roads) are acumulated in small areas...

Well I'll try to little bit more balanced the theme and we'll see :)

It can be a median ( more stable ) or arithmetic mean ( easier ) for the already processed tiles. There could be implemented statistical model next zoom level has 1/4 of roads of the previous level, so various zoom levels can be compared. The adaptation would be triggered after some number of tiles was procesed to avoid initial instability. There can be implemented hysteresis for the threshold to avoid oscillations.

Other ideas regarding adaptive road rendering for wide road density scopes, for navigation context.

1/ There should be maybe displayed roads of the class of the current road and better, to provide road network context. E.g. If going along a secondary road, secondary roads and better should be rendered. As there is usually high zoom level due autozoom, the displayed should not be road-flooded.

2/ Instead of road count or road length sum, there can be counted the ahead crossroads along the route to be eventually displayed. If the adaptive zoom range ZN-Z12 was used for secondaries, they would be rendered at ZN-11 only if there would be max N crossroads ahead, e.g. 2.

Various themes and various contexts of these themes differ a lot.

Aside of internal themes, review set of available external themes - see Theme section on Locus forum , aside of Elevate/Elements theme (usable for LoMaps as well), I referred earlier )

Well... I don't wanna to behave like iUser, but... Man could expect that "default maps" (provided by app author) would simply work fine with "default themes".

Good work - I like it.

Hi,

thank you for report! It'll be improved in next version of Locus Map app.

Thank you
