Hi all,

 

 

 

Recently tried to use google satellite images to check out some things on my property in Hornby Christchurch and have noticed the quality is nowhere near what it has been for years. Its seems as though thy have intentionally or mistakenly reduced the quality? I have tried on my phone also using the google maps app to make sure it was not just the computer I was on and it is also blurry on the app?

 

Have to admit it kind of sucks now, I can hardly make out my property from the neighbors!  

 

anyone have any info on why this is?

Probably find that the older images were taken using higher quality settings, whereas the latest ones may not have been set as high. So it's not intended as such, just whoever supplied the latest imagery did a poor job.

They may have had aerial photography rather than satellite photos previously. Local councils often have a GIS viewer with high res aerial photos, or try Apple maps if you have an Apple device.

I think it was deliberately blurred for public use months ago to stop people seeing into the back yard etc.

Yep. Aerial vs Sat.

 

 

 

If you open it in google earth you can go view-historical imagery

 

And scrollbar back and forth to see the changes/updates

There government commissioned some fairly high-res aerial photography (and LIDAR) of Christchurch for earthquake recovery - these were used by Google in their mapping products. Perhaps they've been replaced with more current, lower resolution, satellite imagery

I have noticed this as well, I live in Auckland but Google Maps in general. The satellite image option in maps used to be very sharp and now are largely blurry. It isn't just a Chch/earthquake thing.

Google appear to have made a lot of changes to NZ about 2 weeks ago - updated maps and lots of new traffic routing. The cycling data for Wellington is now incredibly poor and isn't even aware of some major cycling routes (such as SH2 between Petone and Ngauranga) even existing any longer.
