OpenStreetMap
OSM needs a new version of layers ,new imagery satellite layers , I found HERE map satellite its really a new map imagery that we can use full edits and see new roads with buildings… I hope of OSM to add new updated layers for contributing better by users …

Note the Here roads are largely crap. You can see that when you compare to the image layer - roads frequently cross through houses, the typical AI nonsense that allows them to advertise to their customers: We have X kilometers of roads in Iraq - more than any other map service. We will likely see a lot more like this in the future in various places but this is not a role model for OSM!

For reference - here a recent (June 2018) open data image from the same area:

thanks for reply , but this ways its really difficult we can’t map accurately by comparing two maps !

OSM is a collaborative effort for mapping by entusiasts, not an organized venture to map as much as possible for the sake of numeric reports. Which means, if you don’t live in that area and cannot contribute anything without imagery, try another area, where you can. If you do, stop marvelling at proprietary imagery, go out, collect GPS traces and POIs, and map it.
For a base road network, you could politely ask Christoph (imagico) to georeference the fresh low-detail imagery, so you could trace roads from it.

The filename from imagico shows that it’s just from Sentinel-2 which you can process yourself to use as a background in OSM.

@farhadGull as a clarification: no data or imagery from Here is a legit source for OSM editing.
Then: a year from now likely some other imagery provider will likely have more up to date imagery of that location and then somebody else and so. The providers of imagery mosaics update their imagery relatively seldom, as it costs money (in more than one way) and tend to concentrate on regions of the globe where it makes economic sense for them (particularly with respect to higher resolution imagery).
@imagico ever had any thoughts about generating a regularly (automaic updated) global Sentinel-2 layer for OSM use?

@philippec what exactly did you wanted to convey with the link to a competing company?

There is something to learn. Why do you ask ?

You might need be a bit more explicit about what, on topic (current aerial imagery), point there is to lean from Here.

@SimonPoole - you want to finance that?
The main problems of this idea are in parts already demonstrated by Landsat Live from Mapbox:
There are already services that offer online access to the standard ESA TCI rendering of some Sentinel-2 images. For the shown image you can for example use (in JOSM notation):
https://geoservice.code-de.org/Sentinel2/wms?SERVICE=WMS&VERSION=1.1.0&REQUEST=GetMap&FORMAT=image%2Fpng&TRANSPARENT=true&LAYERS=S2_MSI_L1C&time=2018-06-09T07%3A56%3A11.024Z%2F2018-06-09T07%3A56%3A11.024Z&STYLES=&SRS={proj}&WIDTH={width}&HEIGHT={height}&BBOX={bbox}
Note this WMS is currently not advertised for arbitrary use AFAIK so it is not clear if they are fine with using it for mapping. If you intend to use this you should probably contact code-de (contact details in the GetCapabilities or on the website).

@imagico as you probably can guess, I completely realize the difficulty of selecting “good” imagery (though it might be getting easier over time to do automatically).
On the other hand there -would- be significant value in having a global Sentinel derived layer even if not continuously updated (but at least not totally stale), given that it is afaik currently the open imagery source with the highest nominal resolution. Naturally if the pain is large enough (say China) the imagery can already be used now, but doing so is rather convoluted and likely outside the means of out typical mapper.
I don’t think funding would be a significant hurdle as the benefits are fairly clear, so the WMF and others could likely be convinced that the project makes sense (obviously other free imagery sources could be added where available, but that would be an undertaking with a far larger scope.

It is possible to see the marking of some new streets in the Bing image.
