How can I figure out the exact geographical coordinates of my house?

Try Google Earth.  It appears to be fairly accurate if you are in the U.S.  I have used it in my job, comparing it to a different data source, and have had good results.  Plus, it's just kinda fun!

All GPS can tell you is your location on the earth. GPS cannot tell you where your property corners are, unless you already know the coordinates of those property corners. Your GPS unit does not know where your property corners are until you provide it with the information it needs. \n\nIf you knew the coordinates, which could be either latitude and longitude that mappers use, or state plane coordinates that surveyors use, then you could use GPS to guide you to the corner locations. But since you do not know where the corners are, you have no way of entering the required data into the GPS unit. \n\nYou not only need to get a professional surveyor to survey your property, you also need to tell the surveyor that you need him to provide you with the state plane coordinates of those points, so you can enter them into your GPS unit, then you will be able to find them yourself in the future.

Your home coordinates are the number of degrees and minutes a direct line from your home to the centre of the earth deviates from the equator and the Grenwich Meridian. There are many ways you can find this out using various maps and things (like the website below).\n\nBut I doubt that there is anyone out there psychic enough to guess it. But I'll give it a try anyway...\n\nN38o59' W77o05'\n\nHow did I go?

If it's just for the room itself, you measure the length of the room and the width of the room and draw that rectangle on a sheet of paper and label the edges with the actual measurements you found.\n\nMore details you could add would be location of electrical outlets and light fixtures, doors and windows (all with measurements of their size and location).

I haven't used this, but it looks fairly simple (as opposed to the professional mapping products):\n\nhttp://www.smartdraw.com/specials/geography.asp?type=12195&id=12195\n\nGood luck

A database with the longitudes/latititudes of almost every place on earth can be found here. I suppose you do know where you were born.\n\nhttp://www.heavens-above.com/countries.asp#P

hello J, before you can figure out that complex question you must first declare what piece of ground your home is located at. as an example your state , then maybe city, or county, or parish, then quite possibly a street name. ask mom then come back with that info then maybe i can ask my mom  and we can get you the help you need. so go now and i will wait. go on im waiting

Same as a GPS. It triangulates the exact position

Not every city map is that descriptive but yes you can actually find your house on Google Earth if your city map on Google Earth is the satellite picture of your city\nTry NASA's World Wind version 1.3 its very good\nhttp://worldwind.arc.nasa.gov/

OS maps with contours will do the trick to a reasonable accuracy. If you want real accuracy you will need to level to the nearest OS bench mark or get a GPS reading from an instrument which gives height as well as grid location.\n\nFurther info after reading another answer.\nI am talking about UK here where the ground levels can change quite dramatically from street to street unlike the previous US respondant who must live in a very flat area of the States.

you can do the google earth thing. or there are loads of maps online.  Also your county courthouse should have plat maps if that is what you need.  It would help if you explained what kind of map you are seeking.\nplat, terain, flood plain, general area, what magnifacation.\n\nI love google earth... I have lived in many locations and I found my old homes real easy and the detail is great... it is kinda slow tho.

How can we know where would we be... if we don't have maps?

Usually your given an area code from the same area code as where you live.  So you can generally say, yes, you could figure out where the person lives.
