different regulation on land use than the other. Both problems are possible to be
resolved by the integration between the data sources. As national land parcel
database is not only counted on its own data, it also relies on land parcel database
from different states (National Research Council 2007). Lastly, all data have some
sensitive personal information when stored in a local or state level. The improper
management of data security could be harmful when the details of the data are
leaked. The removal of personal and sensitive information is needed when managing
land parcel data in agro-geoinformation systems.
9.5 Approaches to Manage Land Parcel Information
in Globe Agro-Geoinformation Systems – International
Standards
Global agricultural study requires data sharing between countries. As one of the key
features in agricultural research, land parcel data is needed to be shared between
countries as well. The Federal Geographic Data Committee (FGDC) and American
National Standards Institute (ANSI) are two major standard institutes in the United
States. Both agencies focus on standards inside the United States, such as the
National Spatial Data Infrastructure (NSDI) (National Research Council 2007).
However, mainly the foci of standards in NSDI serve for data accessing and sharing
