  We study forecasts for the accuracy of the determination of cosmological
parameters from future large scale photometric surveys obtained using the full
shape of the 2-point galaxy angular correlation function. The effects of linear
redshift-space distortion, photometric redshift gaussian errors, galaxy bias
and non-linearities in the power spectrum are included on our analysis. The
Fisher information matrix is constructed with the full covariance matrix,
including the correlation between nearby redshift shells arising from the
photometric redshift error. We show that under some reasonable assumptions, a
survey such as the imminent Dark Energy Survey should be able to constrain the
dark energy equation of state parameter w and the cold dark matter density
\Omega_{cdm} with a precison of the order of 20% and 13% respectively from the
full shape of the angular correlation function alone. When combined with priors
from other observations the precision in the determination of these parameters
improve to 8% and 4% respectively.
