Hi, does anyone know if it is possible to download the older version of maps e.g. Google maps, ESRI, Bing using SAS.planet (ver. 190707)? I tried to set different time intervals in the upper bar, I tried to set up a date limitation in Selection manager window but I’m still getting the same latest map. Thanks for sharing any tips.
Maybe there are not any other images available. If you click in the image, then right click in your mouse: go to where it says Additional Operations, Images available and there you should find which images you have and from which dates they are. Good luck!
Sergio Acosta Y Lara thanks a lot for the advice. However, I'm still confused a bit. Despite following your manual the given results are not clear to me. Even though having google satellite map as a base map (later I tried other providers as well) it still shows only ESRI details. Am I doing something wrong? Thanks, Tomas.
Yes you are right. In my case it shows me an error message. Maybe it's something that needs fixing yet. You can try asking in other lists. I'll do it too
DEar Tomas, did you solve your problem? I need satellite images from different years and I am trying to learn how to download them. I read your messages but obtaineng the same results than you, even I hace three available images from my area is impossible to download the older...
Any suggestion will be useful
Kind regards,
Maria
Dear Maria M. Sampietro Vattuone actually so far no, I dindť find solution yet. Soon I will be working with GIS data again so I will submerge into this subject again. So let's see if any new findins will be done.
PLease let me know if you find how, I'll do the same if I do...
Kind regards,
Maria
Still wondering how can I download older imageries? I am stuck with similar situation.
Maria M. Sampietro Vattuone If you are just looking for satellite images you could try here (remember the "date range"):

Christian Renner, thank you for your answer, the problem is the quality, there are several old images, but I can not find those similar Google Earth but on earlier years. I'll chek all links you suggested.
If you are talking about the spatial resolution, this depends on the satellite used to capture the images. I think "landsat 8" - which is used a lot in my area - has a resolution of 30 to 30 meters. You might look for "rapid eye" images: Officially the program was closed, but the satellite is still functioning I guess. And as you are looking for older images you migth find something usefull. The resolution is a lot better than the one of landsat: Ground sampling distance (nadir): 6,5 m; Pixel size (orthorectified): 5 m.

The "sentinel" satellite has a 10 m spatial resolution, I think.
But my knowledge of satellites is a "remote" one.. If you get the joke..
You could try here, maybe they are willing to help you. At least there are always some interesting courses beeing offered, for free (NASA arset):

Hope I could help in anyway..
