OpenStreetMap 開放街圖
My wish for OSM would be to have its underlying satellite photos updated more often. That would really help keeping the map up-to-date. As of now, the satellite photos are severely outdated. I am helping to update Qatar and with the breakneck pace of the road development in this country, it would be tremendously helpful for mappers to have up-to-date satellite photos on OSM.

Note that OSM itself doesn’t provide or manage satellite imagery. It relies on third-parties that kindly allow us to use their imagery for mapping. Aquiring and processing high-res imagery is a time-consuming and costly business, so it is often not very up to date nor comprehensive.
The most widely used imagery comes from Bing, but there are other providers, from mapbox (who promises low-res but frequently-updated imagery soon) to local sources to self-made shots using DIY balloons or drones. If you ue JOSM, there is a nice pre-made list of existing imagery, and with any editor it is easy to add imagery not in the default list if you know the link. Have a look, maybe some sources are more up to date than Bing for your area.

Thanks Vincent. I have registered for Mapbox account and found out that to have underlying satellite photos, we have to pay.

If you are in a hurry, you may want to acquire level 3A orbital orthophography from a provider such as RapidEye: http://www.rapideye.com

I don’t know how much attention is payed to this page, but it exists and it couldn’t hurt to add your request to it.

You need to pay mapbox to see their satellite imagery as a user, on your mapbox map. But like with Bing, OSM contributors have a special permission to use them for free to improve the map.
Taken from JOSM’s default list of available imagery providers, the url is tms[17]:http://{switch:a,b,c}.tiles.mapbox.com/v3/openstreetmap.map-4wvf9l0l/{zoom}/{x}/{y}.png With JOSM you just go to preference, tms/wms, and activate the corresponding entry. I’m not sure what the procedure is for other editors.

Thanks again Vincent. I installed JOSM but everytime I click on the Edit option, I keep getting this message: “Editing failed - make sure JOSM or Merkaartor is loaded and remote control option is enabled”. My browser is IE 10.

You should try Firefox or Chromium -
or just use the download button in JOSM and use the slippy map there to edit the region of your desire.
