I'm using (or try to) Here Maps for my iOS Application. I just downloaded the example project. Just including the map and a few markers (Same problem without markers).
The problem is, when I try to zoom in our out with the pinch gesture (using the build in function from hereMaps) the tiles turn white with the "here"-Logo on in and it takes several seconds to load the real maptile. Thats waaaay to slow. Compare it to google maps, there is not a single loading tile. I did not changed anything. Don't know what to change anyway, its just a few lines of configuration code.
The question is: Is that the normal behaviour? Is there a few to speed it up?
Testet with several WiFi's. Screenshot attached.
Thanks! :)

Layers are being rendered in 3d, making them difficult to click, and look bad in general.
As you can see in the image, the dots are rendered about 500 ft off the ground. I'm not aware of any configuration changes I made to enable this, and I can't figure out how to prevent it from happening, although it only seems to happen to some layers (as you can see in the screenshot)
I've tried reordering the layers in Mapbox Studio, but I don't know what else I would change, as this seems to happen regardless of any js changes.
It seems like this was an issue with react-map-gl not being able to render 3d styles correctly. Setting the map to "2d" in Mapbox Studio and using a raster source to generate the 3d terrain seems to have fixed the issue.

I need a clarification. Today I bought a new Android 10 Samsung device to test apps... and all captured images are shown rotated wrongly inside the Labels. The code is very minimal: takes a photo and then shows it in a Label. It works fine on my iPhone and my old Android device, but in this new Android device the image orientation is not detected correctly by Codename One.
Is it a bug of Codename One or is it something that needs coding in the app?
In the latter case, can you give us a code to take photos in the correct orientation? Thank you.
I think there might already be an issue on that, if not there should be. The gist of it is this... Some modern phones always take the photos in the same orientation and just mark the photo as rotated to X degrees in its tags.
This works usually since most apps know to show the photo rotated. Currently we have a workaround for that in the gallery API but that's a bad workaround. A good workaround would be to check that flag every time we load an image and rotate it dynamically. It would be inefficient but it would solve that problem once and for all.
I created a PeerComponent, that is a port in Codename One of the Horizon Camera SDKs. At the moment, it simply shows a live-preview of the camera.
I tried to add a Label over the PeerComponent: the Label is on top only in Android. On iOS, the Label is on bottom (that means invisible).
I've done a lot of trials to get a correct z-ording on iOS, without success.
My question is which tips, suggestions or checks can I do to make z-ordering working properly on iOS also. Thanks.
Normally it should "just work", there is no special treatment. I think horizon paints in an area we rely on and doesn't paint when we expect it to. Looking at their sample code I see that they reference top and bottom elements which might allow working around this.
We are developing a WPF application, mainly using the WPF Bing Maps control.
We have multiple tile layers which can be turned on or off at runtime. The tile layers retrieve their data using a custom tilesource, so we have more control over the uri returned.
When the application starts multiple tilelayers are visible, causing calls to our restservices to retrieve the tiles. The services check the DB for images, if present, return the images, if not, generate the images, store them, and return them. So far it works like a charm.
Now the following 2 cases: DB gets cleared for some reason -> Services just recreate the images when the calls are made, and returns them. No problem here.
If someone clears the IE cache (client side), while the application is still running, zooms / moves around the map. The tiles loaded before disappeared, and are not coming back. When zooming in further, it does retrieve tiles that were not loaded before, but leaves us with big gaps in the tile layer(s).
Only way to solve this seems to be to close the application, clear IE cache, clear DB, and start again. What causes this behaviour? And why are, seemingly empty, images loaded?
After some digging around an option would be to give a tick parameter to the uri, so it will always retrieve new tiles. But this has a major performance penalty.
Any advice on how to solve this problem?
Thanks in advance.
The tile layers in WPF cache the tiles and pulls the tiles from the cache if it has already loaded it once. If the cache is cleared then those tiles will not be reloaded. This is by design for performance. Especially for tile layers that do not have all possible tiles. There is no way around this.
I am looking for a light-weight map component that displays a map of the US and allows users to click on a State and see information pertaining to that state. The data I want to display is in my database. I just need to know what state was selected so I can display the detail. This is something I am doing to get familiar with Silverlight.
All the searches for Silverlight/ Maps I have done so far have pointed me at solutions that are far more complicated than I need. My perception is that using Bing Maps to do this simple task would a waste of the features provide by Bing.
Anyone know of such a Component? Am I wrong that Bing Maps is not the right tool for the job?
TIA!
If you have access to Expression Studio (specifically Expression Design), creating maps as vector based images is quite easy. Poly-paths in Xaml are also relatively efficient to store and serve up compared to images.
You import a map as a background image and use the pen tool to dot-to-dot trace around the country. Combine all those path segments into a single path. Then create a separate poly-path for each state (close them to allow for a fill).
It will take a few hours to build all this (I know having done this for a world map country selector... took 4-5 hours solid for the one polygon styled below):
By having each state represented by a filled polygon-path highlighting (by changing the fill colour) is trivial on mouse-enter/mouse-leave events.
If you want stylistic map, remove the image, otherwise use transparency on the state polygons to show the map through the roll-overs.
Update:
And if you get yourself a graphic tablet and pen this sort of point-to-point work is about 5 times faster than with a mouse!
The interaction with Bing Maps in Silverlight is really strong and provide you with easy communication between the map and your data. I would give Bing Maps a try.
I'm not sure if you've already come across this, but it seems you can also use the control with custom tile sources. Here are a few resources.
