Yes, images of your house/area will be older. Near real-time imagery is only available at lower zoom levels.

It takes a long time to take satellite/aerial photos of everywhere on the planet in high resolution, so 2018 is quite good in the geospatial industry.


Not quite, but you can see the contrails. Example: https://zoom.earth/#view=40.174,-136.065,7z/date=2020-07-20,... Change the date to see them being created.


Yes, near real-time is available up to 500m/pixel (level 8 zoom). To see higher resolution you can use planet.com but that’s a commercial service.


Yep, it will be old at that zoom level. Zoom out to level 8 and you’ll get near real-time but you won’t be able to see your house.


Yes, the night side uses a combination of infra-red imagery with a static image of the Earth at night. Without that image all the landmass and cities would disappear into black, so it helps give the IR imagery context. And it looks nice. It’s a common technique called GeoColor.


Planet Labs do this (planet.com) but $$$


High resolution will be older imagery. You won’t be able to see your house in near real time unless you pay to task a satellite from a commercial provider like Planet Labs.


I'm the developer of Zoom Earth. "Live" is shorthand for "near real-time". But, you're right. Most visitors simply want to see their house from space. Which is understandable, but also kinda depressing. They could look at _anywhere in the world in near realtime_, but they wanna see what their roof or garden looks like.

Meteorologists love it though.


Also, it's good for monitoring wildfires. For example, here are fires currently raging in the Arctic: https://zoom.earth/#view=67.86,151.46,6z/date=2020-07-20,am/...


I guess it's pretty normal to check your own place because you know it well enough to rate the quality of the imagery. In this case, whatever you're using offers better and more recent resolution than Google Earth at greater speed so it's my New Favorite Thing.

Do you have a WMS interface?

I'm sure, they are interested in more. They might pick their home first, as they are familiar with it and can compare the pictures you provide with their mental image. You have to gain their trust first.


Why not just say how old each image is, like with a color overlay? “Zoom past this level and you will be looking at 400 days ago” etc


It does - imagery is dated to the nearest month from level ~12 and higher. (See top left on desktop, bottom on mobile)


From which year are the cloudless images shown when deselecting the live/daily layers? There seems to be one per month but all from the same year, right?

It's interesting to see how winter is taking hold of the planet - but a little bit disappointing that I cannot compare snowy areas between different years.


So live/daily is for zoom levels 0-9, and the archive goes back 20 years to 2000. Zoom in, and older imagery dates will vary based on the location.


Some details: It combines near real-time images from multiple geostationary satellites, updated every 10 minutes (with a delay of ~30 minutes). NASA GOES satellite for the Americas, Japan's Himawari-8 for Asia and Meteosat in Europe/Africa. Zoomable up to 500m per pixel. Beyond that it uses historical imagery from Microsoft and Esri.

It also tracks the latest storms and hurricanes https://zoom.earth/storms/


Can you use ESA Sentinel satellite imagery as an intermediate step? It's 10m ish resolution updated on a roughly weekly cadence.

I use it frequently (via https://apps.sentinel-hub.com/sentinel-playground/) to help plan backcountry trips around here, as it's great for seeing the local snow conditions.


I’d love to, but their API is currently cost prohibitive for a free-to-use website.


Oh, that's interesting. ESA says they distribute the Sentinel data free of charge as far as I can tell. So I guess the issue is that you'd need to download and host the data yourself, rather than just do an API call to someone else's archive?

Anyway, it's a cool website, nice work!


Yeah and hosting it by yourself is slightly non-trivial as the storage requirements are in the PB range.


You’re exactly right. Sentinel Hub process a huge amount of data in real time, so it’s no small feat.


There's no reason why native apps and the mobile web can't peacefully coexist and thrive. There isn't going to be a "winner." It's not a zero-sum game. The future will be more of what we have today: more apps, more websites, more devices. But nothing is going to die, or be killed off by the other.


I agree. Hence why I said I didn't think Apps were going anywhere either.

Apps have a lot of really cool strengths. But killing the web- that's something people who have trouble seeing long term trends say.


Fighting for mindshare with click-baity headlines ;-)
