1. Introduction The World Wide Web (WWW) will be a major and vital, data sharing system for humankind in the 21st Century. Because of its prominent position as The International Society for the photogrammetry, remote sensing and spatial information sciences and technologies, it is essential that ISPRS maintain a very visible and active position on the WWW through the creation of colorful, exciting and informative webpages. However, the primary function of these webpages will be to convey, share and distribute information. Therefore, the provision of information should not be secondary to graphical design. The provision of optional text-only pages should be provided whenever possible, in case users do not have access to advanced internet technology. Lengthy download times should be avoided for crucial information.

Conveyance of important information is paramount. Therefore the webpages must be informative, creative, and entertaining, constituting an intelligent, practical and resourceful promotion of the ISPRS and its activities.

2. Responsibility to Prepare Webpages

i. All ISPRS Member Organisations, Commissions, Working Groups and Technical Commissions should use Internet webpage media to promote their work related to their area of expertise.

ii. ISPRS mandated restrictions placed on the development of webpages will be few. While daunting or intimidating technical complexity is not encouraged, nonetheless the ISPRS is promoting the creation of advanced webpages, with the emphasis on both the clarity of the message conveyed and the innovative creativity that will go into their creation.

iii. ISPRS webpages are not only for ISPRS Members, but also for the larger world audience that is interested in the ever-growing fields of photogrammetry, remote sensing, GIS and related technologies and issues. Therefore, the ISPRS encourages the creation of creative and entertaining webpagesthat will appeal to a larger audience.

iv. A downloadable webpage that can be used as a basic template upon which a webpage can be built is provided at the ISPRS Website: www.isprs.org/samples.html

3. Webpage Design and Content i. Clear and Understandable. All ISPRS webpages are to be clearly and logically organized, so that their purpose and information can be easily and quickly understood. The information should be concise, accurate and laid out simply. Testing of the webpage by requesting all ISPRS officers to read and comment on it before posting on the WWW is recommended.

ii. Graphic and non-graphical. All ISPRS webpages shall be provided in both a graphics-included format and in a non-graphical format.

iii. Logo. All ISPRS webpages should clearly and prominently display the official ISPRS logo on every webpage - downloadable from: www.isprs.org/samples/logos.html

iv. ISPRS Affiliation. A reference to the ISPRS and the function of the Working Group or Technical Commission must be stated clearly at the front of the webpage.

v. Images. Image acquisition, management and processing are the main activity of ISPRS. Therefore, an array of images that demonstrate ISPRS activities should be included where possible (non-graphical options shall also be provided - see 3.ii above). Images with lengthy potential downloading times may be provided in an FTP format.

vi. Hypertext Links. All ISPRS webpages must include hypertext links to the ISPRS Home Page and to other ISPRS Technical Commissions. Links to associated sister- organizations could also be provided.

vii. Design . ISPRS webpages should include the following:

viii. Home Pages of ISPRS Member Organisations should contain the following: names, pictures/photographs, and complete addresses, Commission and Working Group officers; important activities of the Member; hyperlinks to the ISPRS Home Page and to relevant Working Group webpages; and, if available, the address of an email subscription system (list server).

ix. Technical Commission Webpages should contain at least the following: the name and Terms Of Reference (TOR) of the Technical Commission; names, pictures/photographs, and complete addresses of all Commission and Working Group officers; information about Symposia and Commission/WG events with on-line registration forms; and hyperlinks to its Working Group webpages, the ISPRS Home Pages and to other important websites.

Working Group Webpages should contain at least the following: the name and Terms Of Reference (TOR) of the Working Group; names, pictures/photographs, and complete addresses of the Working Group chair, co-chair and members; dates and locations of Working Group meetings and workshops with on-line registration forms; and necessary hyperlinks. 4. Technical Issues of Webpages i. Pathnames. The use of relative or absolute pathnames to link documents or to connect files should be considered for its practicality and user friendliness.

ii. Browser. Webpages should be designed and updated for the most popular browsers in use at the time. The use of a good and fast browser facilitates a quicker acquisition of images.

iii. Links. Links should be checked periodically and updated. Each page should have a link at its end to the top of the Home Page.

iv. Bulk Data. Documents made available in postscript format should be compressed, with an indication of their approximate size, and the method of compression. A decoder should be made available when needed.

v. Java. Java script and applets may be used, but critical elements of webpages should not depend on Java.

5. Other Issues. i. Public Domain Software. It is appropriate to list the public domain software used in constructing webpages.

ii. Cultural Sensitivity. As ISPRS is an international organization, with webpage readers from all over the world, comments and statements that could be misconstrued by readers from different cultures must be avoided.

iii. Liabilities and Disclaimers. The following phrases (or variants of them) should be considered for inclusion in webpages :

iv. Ownership. Data or articles made available through an ISPRS webpage should be available for copying or downloading. Sensitive data or copyrighted articles can be requested by email or from a reference URL.

vii. Obsolescence and Data Purging - All webpages shall be deleted from all search registers within 6 months of completion of the event to which they refer, or closure of an ISPRS Working Group. Similarly, Commission Symposia and ISPRS Congress webpages shall be purged within six months of their conclusion.

viii. System Administration and Security. Provisions must be made for:

ix. Task Force. ISPRS will make available a Task Force of experts that has extensive WWW experience for assistance in certain elements of WWW page creation and maintenance. ISPRS WG VI/4 is in charge of consultation for Internet/WWW in ISPRS.
