2 problems of creating offline map .

[CharlesQHappy]

I followed the document in https://github.com/SimBlocks/OneWorldSDKforUnity/blob/main/docs/ExternalData.md to create offline imagery map. I could see the big picture, but still had 2 small problems.

1. How to traverse all the Geodetic2d point of the whole Earth since it is a vector consisting of real numbers which has infinite amounts?
2. After I got the GeoBoundingBox with the function TileToBounds, how could I get the corresponding PNG or JPEG image?

I have succeeded in resolving the second problem by twisting the "Export" function in the class "GeoOBJExporter". Now I can get the PNG when given column and row and level detail of a tile. But the 1st problem still exists, could you give some hint?

OK， I think I find a way to do that, I just traverse all the coordinate with a interval.

Good job.
