This paper presents the first data evaluation of the ESO Imaging
Survey (EIS), a public survey being carried out by ESO and member
states, in preparation for the VLT first-light. The survey goals,
organization, strategy and observations are discussed and an overview
is given of the survey pipeline developed to handle EIS data and
produce object catalogs. A report is presented on moderately deep
I-band observations obtained in the first of four patches surveyed,
covering a region of 3.2 square degrees centered at and
. The products available to
the community, including pixel maps (with astrometric and photometric
calibrations) and the corresponding object catalogs, are also
described. In order to evaluate the quality of the data, preliminary
estimates are presented for the star and galaxy number counts, and for
the angular two-point correlation function obtained from the available
data. The present work is meant as a preview of the final release of
the EIS data that will become available later this year.
