While investigating this issue I noticed another thing: ![screenshot_2018-08-08 _issue_get-tile-mercator](https://user-images.githubusercontent.com/316517/43833850-6d962a04-9b0c-11e8-8c4c-3ab7a2f65ab8.png) I get the same result regardless of the `masked` and `resampling`. Is this to be expected?

Also, `GeoRaster2.get_tile` (internally `GeoRaster2.get_window`) fails for in-memory rasters: ``` from rasterio.enums import Resampling import telluric as tl from telluric.constants import * rs1 = tl.GeoRaster2.open("../tests/data/raster/overlap1.tif", lazy_load=False) rs2 = tl.GeoRaster2.open("../tests/data/raster/overlap2.tif", lazy_load=False) rs2_alt...

Confirmed original issue: ``` rs2_4326.save("/tmp/rs2_4326.tif") tl.GeoRaster2.open("/tmp/rs2_4326.tif").get_tile(4377, 3038, 13) # Empty image ```

(Notice that there is the combination of two problems here, see #23)

Hit by this today, I might try and fix it.

There is a broader question here, that is: what to do with an operation that produces a result that is not representable in the original CRS? This is exactly the...

Cartopy already visualizes it correctly: ![index](https://user-images.githubusercontent.com/316517/46309542-e9182f80-c5bc-11e8-86ea-d1588da17c9b.png) But the core problem of telluric is still that a `reproject` might turn a valid geometry into an invalid one: ``` In [6]: geod_buffer...
