is very obvious. For ordinary individual users, day map is definitely the first in China, and foreign Google map is definitely the clearest.
Let’s compare the six popular satellite maps at present, and you will understand.
map uses Google, Arcgishml2, Microsoft images, Baidu map, Tencent map, Gaode map, and Tianma map.

comparative site selection: longitude: 121.34725973010066Latitude: 31.19621814921196, here is the northmost point of terminal 1 of Shanghai Hongqiao International Airport , and the west of the canteen of Eastern Airlines .
Comparison data ratio is 1000 meters, 300 meters, and 200 meters below, and a total of 3 groups of
1 and 1000 meters image clarity comparison
Google satellite image
day map image
Arc gis satellite image
Microsoft image
Baidu map
Gaode map
The result is obvious. After comparing the six maps, Tianma map is presented with an absolute advantage, and it must also be the first. Why?
Because the Tianma map was established by the National Basic Geographic Information Center of the Ministry of Natural Resources of our country, it has a standard national font size. Its satellite map is the most authoritative, accurate and clearest.

00 meters ratio comparison, Tianma map clarity is still the first.

relatively clear Google satellite maps and Tianma images below 1200m, Microsoft images are about the same as Gaod images, and arcgis images and Baidu maps are directly eliminated.
Conclusion
Comprehensive analysis, the domestic satellite image clarity is equal to that of Google satellite image. The clarity of some regions is clearer than that of Google Map , followed by Google Satellite Image, and then Gaode Map ;
If you stand from a global perspective, Google Map is the first, Microsoft Image is the second, and arcgis image is relatively the most blurry; Tianma only has domestic images and does not participate in the comparison.
However, in image color rendering processing, Tiandi Map is much worse than Google Map. Google Images look more realistic and natural, while Tiandi Map images have deeper colors, which may be the original film taken by the image and have not been processed technically.
