Travis,

Here are some useful tools:

Welcome to Your Sky, the interactive planetarium of the Web. You can produce maps in the forms described below for any time and date, viewpoint, and observing location.

Translate coordinates (WGS-84, NAD-83, and NAD-27) to and from Latitude/Longitude and UTM. Also, if the location is within the conterminous 48 states, you'll get the converted coordinates for the other map datums.

SOLAR ECLIPSES in Mesoamerica,  AD 1 to AD 1600
The list includes the solar eclipses that were theoretically observable from a number of major locations in territories known to have been the cultural area of the Mayas and Aztecs.
In order to get a sufficient geographical and cultural spread, data for the following locations were calculated:

Greetings,
 
I would like to know how the location of the Summer Solstice sunrise can be  
determined. I have the specific location of an Early to Middle Formative 
period  site (c. 1500-400 BC) in southern Veracruz and would like to know where, on 
the  horizon (i.e., degrees east of north) the sunrise would have occurred at 
 approximately 1000 BC. 
 
Estimates for the contemporary period (AD 2000-2005) are available, but was  
the location different 3000 years ago?
 
Anyone with information that may help can respond to me off-list.
 
Thanks.
