Changing the range of the coordinates on Blender's Viewport I have got Geospatial Data, which has real world coordinates. The minimum and maximums of these coordinates are as follows: 

         X     Y        Z
min    10000   10000  340
max    30000   30000  1100


I wish to fit all the view of Blender, in this range. How would that be possible, either by using the Blender GUI or the Blender Python API.
My suggestion is to use the scale option.

In the image below the real world block is 480 x 480 km, scale is used to map it onto 16 x 16 blender units. Once that choice is made, divide your coordinates by

scene.unit_settings.scale_length


when importing, calculated to give you the correct dimensions in the unit of your data.
