Abstract 
ESA/ESRIN intends to offer the visibility of the “Global Land IKm AVHRR Data Set” archived at ESRIN. The 
experimental Net-Browser called Ionia “lkm” is a customization of the Net-Browser server provided by Intecs 
Sistemi. It gives to the Internet community the possibility to browse remotely the inventory information as well 
as the Quick Looks processed by ESA/ESRIN from this data set. 
1 Introduction 
ESA/ESRIN is archiving since 1 April 1992 the data of the 
“Global 1 km AVHRR Data Set” project. A cooperation plan 
was established among NOAA, NASA, ESA, USGS and 
CSIRO with the aim to insure the acquisition over all land sur 
faces using NOAA afternoon satellite. The project has been re 
conducted for another year leading to a 30 months duration, 
(Buongiomo et al„ 1993). This project is recognized by the sci 
entific community to be the most important for ongoing global 
change studies. It is also recognized that access as soon as pos 
sible to this data set is needed. 
ESA/ESRIN will be in a position to give visibility of this data 
set in April 1994. The visibility of the data set to users is 
assured through the generation of the corresponding QL’s. 
Their collection on CD-ROMs with the appropriate software is 
to be completed by that date as well as their access through net 
work: Ionia “1 km” Net-Browser. 
The design of this CD-Browser and of the Net-Browser soft 
ware take into account the very positive comments received 
about the Ionia CD-ROM product. The requirements emitted 
by the initiators of this “1 km” data set and namely the global 
change researchers were driving the implementation of this 
service. 
2 The Data Visibility 
Based on past experience the data visibility is assured through 
an inventory (also called Catalogue) which is a hi gh level de 
scription of the archived data products and a Browse products 
data set (generally a set of Quick Looks). The way of physically
