Hi Team, Greetings for the day.

This is Godfan. Being a passionate mapper, I just want to bring up a case to top of your box which i feel it as challenging in mapping .

While working on few countries, I have noticed that Digitalglobe Premium imagery shows different imageries at various zoom levels why so?

So in case if Digitalglobe premium imagery is the only latest imagery available compared to all the available resource how do we need to deal with creation of roads and alignment.

Query: Do we need to freeze our view are to a zoom level where we see latest tile imagery and create roads and align to possibly best?

Request you to please look into this case and provide resolution to deal with data in such cases. Thanks in advance

Thankyou, Godfan.

Having the same issue with DigitalGlobe for several months now. And I'm still waiting for an update from DG to fix this. In my country, DG Standard has this problem of showing different images at different zoom levels, and DG Premium even has blank tiles at highest zoom levels (it's unusable for mapping buildings for eg.) 😕

a) in the end you need to ask DG

b) imagery mosaics are always built from different sources/individual images depending on what is available, so what you are seeing is completely normal

c) given that the world is a big place, the imagery providers typically have not inspected everything in detail. In general they are quite happy to receives indications of areas where things may be sub-optimal.
