DATA ACCESS POLICY FOR THE LTER NETWORK

1) There are two types of data: Type I (data that is freely available within 2-3 years) with minimum restrictions and, Type II (Exceptional data sets that are available only with written permission from the
PI/investigator(s)). Implied in this timetable, is the assumption that some data sets require more effort to get on-line and that no "blanket policy" is going to cover all data sets at all sites. However, each
site would pursue getting all of their data on-line in the most expedient fashion possible.

2) The number of data sets that are assigned TYPE II status should be rare in occurrence and that the justification for exceptions must be well documented and approved by the lead PI and site data
manager. Some examples of Type II data may include: locations of rare or endangered species, data that are covered by copyright laws (e.g. TM and/or SPOT satellite data) or some types of census data
involving human subjects.
