cooperation. This Directory is necessarily incomplete
because of the difficulty in obtaining accurate and timely
information about all education institutions around the
world in a range of languages. Therefore education
institutions are encouraged to provide their new or updated
details of education and training programs in the remote
sensing and spatial information sciences.
e Tutorials in Photogrammetry, Remote Sensing and GIS
e News about satellite missions and launches
e Glossaries and Acronyms used in Remote Sensing, GIS,
Radar and Cartography
e Journals of Photogrammetry, Geodesy and Remote Sensing
Working Group VI/1 provides also a big database of education-
related links, including training opportunities, online
publications and journals, continuing education courses,
educational institutions, free software, missions and instruments
information (http://www.commission6.isprs.org/wg1/).
The ISPRS web site contains also a list of job opportunities.
The Employment Opportunities archives is a jobs listing
intended to provide offers for people who are seeking an
employment (http://Www.isprs.org/job_opportunities/).
Messages are posted via e-mail and last until when the position
is taken. Employers and universities are encouraged to submit
advertisement in the ISPRS archive.
Educational resources and job opportunities can also be found
in the Academic Sites for Geomatic Engineering, maintained by
Robert Kauper. It is a collection of links to international
academic institutions that provide education in the field of
Geodesy, Photogrammetry, Surveying, Cartography and GIS
(http:/www.lrz-muenchen.de/-15831aa/WWW/Links.html).
3.5 ISPRS Events Calendar
The ISPRS Events Calendar (www.isprs.org/calendar.html) is
one of the most important parts of ISPRS web pages. The
Calendar contains a list of all ISPRS and Sister Societies (FIG,
ICA, IAG, IHO, IGU, etc.) sponsored and co-sponsored
workshops, symposia, tutorials, conferences, congresses, and
other meetings. It also contains details of all international and
national events on topics related to the activities of spatial
information, photogrammetry, remote sensing, geomatics,
surveying, mapping, machine vision, image processing and
similar areas. One of the purposes for this Calendar is to allow
people of WGs, Commissions and Sister Societies to identify
open dates or events, which they may link up with or avoid
conflicting with. This Events Calendar was compiled manually
by previous editors and contained some incorrect information,
or missed some important events. The current Editor (2000-
2004) has established an automatic system [Chen, 2002] to
search. the events information of geo-spatial information,
photogrammetry, remote sensing, surveying, geomatics, and
GIS on the Internet.
3.6 ISPRS Server statistics
Since the beginning. (1995), the ISPRS server statistics are
available to analyse the interest of the community. The logfile
of the Apache server is examined with Analog [Analog, 2004],
a program that analyses servers' files. Figure 17 (upper) shows
a monthly report of the number of requests to ISPRS server, in
the period January 1995 - April 2004. The increasing interest of
the community for the ISPRS homepage is evident. The graph
gives a reasonable estimate of the use of the server as only the
request for single HTML documents are counted and requests
for images, graphics, icons etc. are not taken into account.
Moreover these statistics refer only to requests made outside
ETH domain, which excludes all the accesses during the
maintenance of the documents. The data missing from the
figure in the period July-August 2000 is due to the movement
of the server from Delft to Zurich.
Figure 17 (lower) shows instead the average request per year.
The steady increase of the use of the HTML documents over
the years and especially after the registration of ISPRS domain
is obvious.
In 1995 the average of monthly requests were 424, in 1998 the
average was 5780 while at present ISPRS server has an average
of 190 000 requests per month.
The different domain (~country) served at least one by the
server were 160 (ca 65% of the registered country code
domains); the distinct hosts served (~users) were ca 228 000
with an average of 20Mb of data transferred per day. More than
20 000 different organizations have contacted the ISPRS server
with ca 4000 successful requests per day.

Another interesting statistic provided by Analog concerns the
words and queries used in the search engines to find ISPRS and
its related pages: between ca 30 000 search terms, the most
used are remote, ‘sensing’, ‘photogrammetry’ and ‘isprs’.
Considering all the queries, the most requested are
'photogrammetry', 'isprs', ‘remote sensing’, ‘International
Archive of Photogrammetry and Remote Sensing’, 'isprs
journal of photogrammetry and remote sensing’ and 'orange
book'. The browser most used to find information related to
ISPRS is Microsoft Internet Explorer followed by Netscape.
The majority of the users (67%) has Windows as operating
systems; then Unix (Sun + Linux) and Macintosh (Figure 18).
The information (directories) more requested contain the
publications, the events calendar and the technical commissions
while 73% of the consulted files are PDF articles.
