Map types
Posted: 3 Apr 25, 10:26
 
I was surprised to see this in the latest Tiger release notes:

The "Hybrid" and "Terrain" Map types were removed, as Google does not support them as initial views.

I just checked the API, and all four types are still listed, with no indication of any of them being deprecated. Did a quick test (with one of my own skins), and I can get initial views with any of the four types.

What am I missing here?

Are you using API 3? Whenever I set Hybrid, it ends up in Satellite, and the Terrain in Roadmap. The type selector allows "Terrain", but not as initial. I searched the net, and other users had the same experience.

I have checked the API, and it seems these map types are still supported. I don't know why it doesn't work for me and why other users faced the same problem.

I see now: Hybrid means "satellite with labels", and "Terrain" means "roadmap with slight topography". I'll readd it soon. It just does not make too much difference to recognize it's a different type.

Roadmap shows road lines and labels.

Satellite is just an image.

Hybrid is an image with road lines and labels.

Terrain is shaded terrain with road lines and labels.

Showing shaded terrain without anything else would be useless. You'd never know the location of what you were looking at. And the shaded terrain is not available at higher zoom levels, so if there were no road lines or labels, as soon as you zoomed in, you'd be looking at a blank screen.

What's lacking are true topographic maps, with contour lines at 20ft intervals. Google maps aren't for backcountry hikers!

OpenMaps, of course, has just the basics. It's a bit like looking at a Degas ballerina drawn as a stick figure.

The answer to this is: No, that is not correct!

Example #1:
OSM: Isgrotta på Larsbreen
https://www.openstreetmap.org/node/5823114703

OSM: Isgrotta på Longyearbreen
https://www.openstreetmap.org/node/4152009620

Google: Isgrotta på Larsbreen
https://maps.app.goo.gl/JM6wYpSEwJ71tHcf9

There is no entry for Isgrotta på Longyearbreen on Google

Example #2:
OSM: Sykehustrappa
https://www.openstreetmap.org/node/5703017722

There is no entry for Sykehustrappa on Google

Example #3:
OSM: Einar Sverdrup Obelisk
https://www.openstreetmap.org/node/5694823921

There is no entry for Einar Sverdrup Obelisk on Google

Bottom line is, the precision of OSM is way better than Google, way better.

If it comes to satellite images, then of course Google is top, because there are no satellite images on OSM.

Just my 2 cents. Cheers, Markus

Just compare the precision of the road lines and buildings in reality (satellite) from Google and Toposvalbard to the roadmap of Google. The Google version is just hilarious.

So, how good is the OSM satellite view? How about its street view?

And locating the condo I just bought, and which has been in the same place since 1985, it misses the location by a mere 1100m. ;)

ETA: And in that condo development, which began in 1975, there are 2900 houses spread over 5 km². OSM doesn't have a street address for a single one of them. All blank boxes on the map.

You have a lot of choices, depending on where you are :

So which one should I choose?

See the problem? For the typical user, this is a bewildering forest of mostly dead ends. It's a bit like steering someone to Linux because they don't want to be ensnared by "the man!" Down the rabbit hole they go.

As I said, I know that there is no satellite view on OSM, but that is not the point (to me). If I need a satellite view I use other sources than Google.


Street view Norway:
https://kart.gulesider.no/m/htUaC

Satellite view #1
https://www.gulesider.no/kart?l=aerial&c=69.650705,18.954932&z=18.84
https://maps.app.goo.gl/DPgsgAk6Aq9fUHGd6

Satellite view #1
https://www.norgeskart.no/#!/?zoom=17&lon=90135.33&lat=6741827.12&project=norgeskart&layers=1003&markerLat=6741830.839778967&markerLon=90119.95768880192&p=searchOptionsPanel&sok=Rallarvegen
https://maps.app.goo.gl/B5g3mDvKtuU14swp8

And locating the condo I just bought, and which has been in the same place since 1985, it misses the location by a mere 1100m. ;)

Maybe Google is better in the US, but in Europe other maps give better imagery.

Another advantage of OSM is that you can display an infinite number of other overlay maps with extremely detailed information. Thanks phil44 :-)

Not a user has to choose those overlays, a developer of a web site chooses an overlay which makes sense.

So, to incorporate "better OSM" into a skin, I'd need to quiz the jAlbum user on where most of his site visitors are coming from, and what they're most interested in. I'd probably have to incorporate an AI module to help choose the right leaflet, and do the Javascript coding.

Most jAlbum users are not web site developers. Most of them probably wouldn't even qualify as "techies." They're photographers, people with families, school teachers, travelers, and so on.

I was hesitant about adding OSM for a long time. Still, the final kick came when Google limited its free tier to one-third of the previous. Now, they are deprecating even the most basic functionality, the Marker (placemark), offering only a cloud-based alternative. So, every time a user wants to create a map, it's not enough to create an API key; they also have to create a control panel for the marker styling. Couldn't they fall back to a default styling if a user doesn't do this? I mean, a placemark is not quantum physics. Not everybody wants to tweak its look.

I feel better with OSM, and even though it's far less refined, I don't have to worry about usage limits and regular deprecations.
