which is a translation from the Dutch text with which the Zee-Fakkel was originally
published. Subscribers will also be entitled to a free copy of the introductory study by
the author which is being written especially for this edition. The atlas was published as
a complement and fitting counterpart to the memorial edition of Blaeu's Le Grand

INTRODUCTION
Maps are very efficient means of communication. They are used as indispensable
aids for travelling, sailing, research and many other purposes. Once the map has
been called a promotor of business. That is probably the reason why the
Rotterdam Municipal Port Management decided to publish a special smael-scale map of
the Rotterdam seaport and industrial area. By order of the Port Management such a
map at the scale 1 80 000 has been compiled and prepared by the Cartographic
Division of the Public Works Department of Rotterdam.
The time available for the preparation of the present edition has been very short
(only two months). A special design and a very simple reproduction method has
therefore been chosen. The selected method afforded also the opportunity to carry
out additions and corrections during the whole process up tili the plate-making,
resulting in extreme up-to-dateness of the final map. In addition, the completion of
corrections did not depend on complicated technical equipment. This saved time and
made the process more flexible.
A first glance at the map reveals the lack of a grid or any other reference
co-ordinate system. This does not mean that the map is missing geodetic control The
whole area has been exactly surveyed and mapped by the Cartographic Division on a
map series at the scale 1:10 000 (City Area of Rotterdam). This large-scale map series
which has an excellent planimetric accuracy, provided the base from which the
Rotterdam-Europoort map has been compiled.
