GIS Tips – GIS and the Law

I love my job, whether creating works of art or building a new tool for automating some mundane task, it keeps me busy and stops me from causing trouble. One thing I don’t enjoy though, is the legal side of GIS.

Every data has a source, which someone, somewhere has created and owns rights to that data. A typical map or cartographic representation may contain 10 to 20 of these layered data sources….so where on the limited space do you put all those sources, furthermore, who are they? They were probably supplied by your line manager who got them from a sub-contractor who got them from a surveyor who nobody got the name of……

There are a wealth of books on this subject, I know, I have all 4 of them and was looking to write one myself, probably entitled something like “Before you publish your map, caveat EVERYTHING”, until I came across the Maine University website for the “First Readings of GIS Law“.

There are some great resources here and references to books which I have only heard of. Please have a read of some of the page below.

Written by Professor Harlan J. Onsrud of University of Maine.


First Readings in GIS Law

Note: The readings referenced in the following paragraphs are recommended for obtaining an initial overview of the legal issues surrounding the use and development of geographic information technologies and databases. HJO

The use of geographic information technologies is pervasive throughout business, government, industry and the scientific community in the United States. Conflicts are arising on a daily basis for those using geographic information systems and their affiliated databases, for those implementing such systems, and for those designing the next generations of spatial information technologies. Balancing among competing interests and resolving conflicts involved in the use of these technologies are growing problems for numerous parties within society. Among the problem domains of greatest concern in use of these technologies are those involving personal information privacy, intellectual property rights in geographic information, liability in the use of geographic data sets, public access to government geographic data sets, public goods aspects of geographic information in libraries, and sales of geographic information by government agencies.

Conflicts in regard to personal information privacy have become much more pervasive throughout the geographic information community within the past few years. Clarke (1999), Marx (1998), Hernon (1997), Curry (1997), Ontario (1997) and Onsrud et. al. (1994) provide more extensive discussions of the range of privacy conflicts in the use of geographic information. There also is a burgeoning literature on information privacy issues generally. A search of “information privacy” on Uncover reveals over 400 professional journal articles published in just the past two years alone. Also witnessing unprecedented growth in addressing information privacy issues are books, government reports, conferences and web sites (respective examples include book: Agre and Rotenburg (1998), reports: U.S. Dept of Commerce (1997), U.S. Senate Judiciary Committee (2000) conference: Cyberspace or Privacy: A New Legal Paradigm?, and web site:

For a discussion of conflicts and societal harms related to competing claims over intellectual property in geographic information (i.e. copyright, other IP, and additional ownership claims based on contract or database legislation), see NRC (1999a), NRC (1999b), Onsrud and Lopez (1998), Pluijmers (1997), Silverstein (1996), Karjala (1995) and Cho (1995).

Liability issues and conflicts over responsibility for damages in the event of harms caused through the use of spatial technologies or databases are explored in Onsrud (1999), Schultz (1999), Stewart, et. al. (1997) and Phillips (1996).

Public use of and access to government geographic databases is often the test case in local jurisdictions for resolving conflicts over access to government data generally. Such cases involve complex sets of tensions between citizens, government officials, non-profit groups and the commercial sector. Access to government geographic databases and the conflicts to which they give rise are discussed in Onsrud (1998b), Onsrud (1998c) and Lopez (1996) while access to government databases in general are discussed in Weis and Backlund (1997). (See also Los Angeles (1999)).

To treat the works in geolibraries foremost as commodities harms other valuable societal functions of information. Conflicts and tensions between the “public goods” and “private commodity” aspects of geographic data in library or library-like online settings are discussed in NRC (1999c) and Onsrud (1998d).

Finally, the sale of geographic data by government agencies and the imposition of restrictions on the use of data gathered at taxpayer expense continues as a highly contentious issue in jurisdictions across the entire nation as discussed in Perritt (1995), Onsrud et. al. (1996), Onsrud (1998a), and, generally, NRC (1999a&b).
