Create a interactive 360-degree photo for Google Maps

yes, this is possible without a prefessional 360 camera.

Use an APP on your phone

I like this free APP

Add GPANO metadata

With exiftool, add tag -XMP-GPano.

To Meet the requirement of 360 photos on Google Maps, the minimal pixels are 3840*1920.

cd /c/exiftool-13.07_64
./exiftool.exe \
-XMP-GPano:UsePanoramaViewer=True \
-XMP-GPano:ProjectionType=equirectangular \
-XMP-GPano:FullPanoWidthPixels=3840 \
-XMP-GPano:FullPanoHeightPixels=1920 \
-XMP-GPano:CroppedAreaLeftPixels=0 \
-XMP-GPano:CroppedAreaTopPixels=0 \
-XMP-GPano:CroppedAreaImageWidthPixels=3840 \
-XMP-GPano:CroppedAreaImageHeightPixels=1920 \
