We study forecasts for the accuracy of the determination of cosmologicalparameters from future large scale photometric surveys obtained using the fullshape of the 2-point galaxy angular correlation function. The effects of linearredshift-space distortion, photometric redshift gaussian errors, galaxy biasand non-linearities in the power spectrum are included on our analysis. TheFisher information matrix is constructed with the full covariance matrix,including the correlation between nearby redshift shells arising from thephotometric redshift error. We show that under some reasonable assumptions, asurvey such as the imminent Dark Energy Survey should be able to constrain thedark 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 thefull shape of the angular correlation function alone. When combined with priorsfrom other observations the precision in the determination of these parametersimprove to 8% and 4% respectively.
