state-wide project for aquifer mapping

[RachealJones]

I'm calculating areas of aquifers of New Mexico. The state is between two zones and I'll likely need to create my own datum. Does anyone know which system is the best to preserve areas in the State of New Mexico?

I  could be wrong,  but this might not be the best forum to post this question. If you post it on one of the other communities, you might get a faster and specific response. http://forums.arcgis.com/index.php

Hi,

You should use Albers equal area or Lambert azimuthal equal area to construct a custom projected coordinate system.

Thank you so much Melita! I found some Texas and California that used those. I appreciate  your help. - R
