We present the galaxy-galaxy correlations as a function of photometric redshift in a deep-wide galaxy survey centered on the Hubble Deep Field - South. We have imaged 1/2 square degree in broad-band uBVRI and H, reaching 25mag in the optical, and 19mag in H. We detect approximately 50,000 galaxies in our survey. Large-scale structure has been well characterized locally using redshift surveys covering very wide fields, but studies at high redshift have relied on pencil-beam redshift surveys or wide-field photometric surveys in a single filter. The photometric surveys measure the galaxy-galaxy correlations in the transverse direction, but are subject to dilution by objects at different redshifts. The pencil beam redshift surveys trace peaks along the line of sight but are not able to measure the transverse size or shape of the structure. We use a combination of the two techniques. We determine photometric redshifts using galaxy template fitting to the photometry. We assign galaxies to redshift bins, and determine the two point correlation function in each bin. We are able to trace evolution in the clustering properties of galaxies out to z~1.
