Abstract
We describe the 2DPHOT package, a general purpose environment for automated source detection and analysis in deep wide-field images. It was designed to be able to obtain both integrated and surface photometry of galaxies in an image, to perform reliable star-galaxy separation with accurate estimates of contamination at faint flux levels, to estimate completeness of the image catalog, and to detect clusters and groups of galaxies using the Voronoi tessellation method. This new environment is intended to be a dedicated tool to process the wealth of data from wide-field imaging surveys. The 2DPHOT package is part of the current efforts which are being made at INPE, for developing a Virtual Observatory structure (projet BRAVO: Brazilian Astrophysical Virtual Observatory).
