[Why are the planets in the Star Wars films so homogenous?]

Take a good look at the planets in our Solar System alone. The variety of environments and regions on Earth is staggering. Deserts, mesas, forests of stone and ice, rainforests, volcanic regions, etc.
Mars has sections of easy terrain and rough terrain, huge canyons, endless fields of dry ice, river deltas from ancient water.
Even some of the moons have varied locations, such as Titan with its mountains of ice, floodplains and methane lakes, and frozen deserts. Sure, some bodies of the solar system are fairly homogenous, like the Moon or Neptune, but there is still a lot of things to be found.
Earth-like planets with life in Star Wars as seen from the outside are usually entirely composed of forest, without hints of polar ice, or equatorial deserts, as if the sphere shape of the planet has zero effect on the sunlights intensity.
Takodana looks to be all lakes and rippling land masses. Tatooine and Jakku are all desert. Hoth is completely covered in snow. Coruscant has no oceans and yet sustains a planetary city. (Corellia actually looks more realistic to me as it at least has oceans, which one would need to maintain a good weather system with rainfall to cradle life.) Ahch-To is one big ocean. Kamino, all ocean. Mustafar, all volcanic.
What's going on here? Why do the planets that feature in the films have almost no variety per region? It's like, oh, Yoda lives in a swamp. Maybe Yoda could go out and find a better home, like in the Tropics. Oh wait, Dagobah has no tropics, because the entire planet is the biome that this scene happens to take place in.
Is there an in-universe explanation for this, or is it just a lack of imagination on the part of Lucasfilm? Even with Episode 7, the choices were basically endless for planetary locations because of modern technology. Why choose the same old method of finding a location on Earth, filming, and assuming the whole planet looks like that?

So, you've seen all of Dagobah, then? Or have you just seen that it looks greenish from orbit, seen that there *is* a swamp on the planet, and then assumed that the entire planet is swampland?

Because if we did that to *your* planet, we would come to similar conclusions from your everglades. Swamp planet. One biome. No deserts or tundra.

>Coruscant has no oceans and yet sustains a planetary city. (Corellia actually looks more realistic to me as it at least has oceans, which one would need to maintain a good weather system with rainfall to cradle life.)

If and only if your planet is meant to support plant life for consumption. Entire continents of other worlds are farmed in order to maintain the populations of other worlds. Coruscant's biosphere is supported by other planets', and our weather is regulated centrally by planetary authorities.

Just because your species has no conception of climate manipulation doesn't mean it's impossible.

>Mustafar, all volcanic.

Fair enough. Like your Io.
