How to plot longitude and latidude

[philoshophy]

Hi
any of you know how longitude and latidude in degree can be plotted in AutoCad or AutoCad land desktop for specific area. Here I am talking about Napa Valley, California. Please let me know

Do you have a point in your drawing of known latitude & longitude? That would be a good start.
You can go from there using the approximate relationship- 1 minute of latitude is 6080 feet, and is [cos latitude x 6080 feet] per minute of longitude.

Depending on desired accuracy, Google earth might give you close enough results.

hi
thanks CarlB I am really appriciate you for your suggestion. But do u know how to match with specific coordinate system for certain area such as napa

 

[CarlB]

Are you sure your drawing is on an established, area-wide coordinate system?

Here's something describing a statewide system that Caltrans uses, might give you some ideas on further investigation.
