Latitude can be measured by observing the stars. Especially in the northern hemisphere where you can measure the angle of the north star above the horizon. That angle is your latitude.

To measure your longitude you need to know the local time and also the time at the prime meridian, i. e. zero longitude. Every hour of difference between these two times is 15 degrees. To do this you need to carry an accurate clock which you keep set to prime meridian time. Then you measure local time by observing the sun or stars. You measure the angle that the sun or a known star is above the horizon and consult a table to see when it is supposed to be at that angle for that particular day of the year. Then you subtract the two times and convert to degrees. Before sailors had good clocks, measuring longitude was very difficult. They could sometimes get a fix on the local time by observing moonrise or moonset and consulting a table but they had to depend on being able to see that event.

Go to Google Earth. Download it. Find your city. It should give you the coordinates.
