Using Blender to map XYZ objects from Homeworld RTS Space map HELP I am new to blender, and not a 3d artist. 

I am making a map for a RTS game called Homeworld. The location of objects in this game are in XYZ coordinates of a 3d space. 
e.g. "Player Object,{3607, -49, -71754}"

I will be adding new objects into a large script file, the game uses, with the X,Y,Z coordinates. There are so many objects and the space is so large it is hard to visualize where everything is. 

What I would like to do is create a Blender workspace that is large enough to match the in game map size, X=47866.359375, Y=27599.160156, Z=44018.109375
NOTE: The blender does not have to be the exact same size I only need it to represent the same size so I can script in 1000's of objects and have a visual representation of where they all are relative to the 3d space.

I would then like to enter, via script, the coordinates so what I am looking at in blender is a map of objects in 3d space.

Furthermore, I plan to add objects in blender to place objects were I want them, related to all the other objects, and then script all the XYZ coordinates to a text file that I can then place in my game map script. 

NOTE: To be clear I am not trying to get blender to make the game map. I am just using it to give me a visual representation of where the objects will be in the game.

Writing scripts is not that difficult for me, however after 1 hour in blender I still could not enter an object at, "3607, -49, -71754" without it being so far off my visual workspace that I could not find it. 

Any help would be appreciated.
Some possible manipulations or information :



Misc possibilities using Shift+S in the 3D view :



Short cuts :


Shift+C : brings back the 3D cursor to the center and places the view so that you see all objects
Home : shifts the view in order to see all objects
Alt+Home : idem but make so the 3D cursor is at the center of the view
NumPadDot : focus on the selection (one or several objects)
Alt+NumPadDot : set your current view center as pivot point (Alt+'.' again to come back to normal mode)


Outliner view, to search for something and select it :



So for instance, the outline allows you to find and select one of your object, then in the 3D view, you can hit NumPadDot to zoom on it.

Surely I miss here many other possibilities.. but hope that helps.

Edit :

Setting the units can also help :
