----------------------------Original message---------------------------- What follows is the text of a proposal the MAGERT Cataloging and Classification Committee hopes to have discussed at the ALA Midwinter meeting. Prior to the discussions, we would like to have some input from the rest of the map community. Please get any comments to Susan Moore by September 29th. ************************************** 1. INTRODUCTION This proposal from the Map and Geography Round Table Committee on Cataloging and Classification requests adding additional character positions to the 007 field for maps in order to adequately describe the physical description details of remote-sensing images. Adding character positions 08-13 will accommodate information relative to remote-sensing images (i.e., when character position 01 contains the value r). For all other values in character position 01 these additional character positions would be set to n for not applicable. As remote-sensing images become more widely available and as the platforms from which the images are taken become more diverse, the need for providing an area to describe the physical aspects of the images grows. 2.
