Zoom level affecting mesh polycount and texture resolution

[onyxlee]

Hi BlenderGIS gurus, newbie here.

While playing with BlenderGIS, I ran into this issue. When I zoom out to a certain level, the satellite imagery texture that it downloads from OpenTopology becomes very low resolution pixelated, the terrain mesh also becomes very low poly. When I zoom in to level 20, in order to get the highest quality imagery, it only gives me a very small portion of the region.

(In the image below, you can see how the zoom level affects the imagery resolution and polygon density.)

How should I do it to get a high res imagery for a bigger area in a higher polycount please? Deeply appreciated.
