example, human development may influence the shape of the parcels (Worboys
1994; Irwin et al. 2003). In addition, land parcel could be influenced by administrative boundary shift such as state boundary expansion/shrinkage after conflicts. Land
parcel may be changed by nature as well. For example, common natural disasters
such as flood and drought could introduce notable change in landscape which will
cause changes in land parcel later (Lin et al. 2019).
9.2.2 Land Parcel in Agriculture
The requirements of containing information are different between the diverse types
of land parcel systems. For example, parcels were grouped into undeveloped and
developed to study residential land use change (Irwin et al. 2003). Data in the
residential research contains more economic variable while not distinguishing land
parcel by agricultural types (Irwin et al. 2003). It is totally fine since the parcel model
were built for studies in residential change which would be unnecessary to including
information about agricultural type for the land parcels.
Land parcel in agriculture mainly focuses on agriculture-related information
while discarding other types of parcels. In general, land parcels, which are not
related to agricultural activities, in agro-geoinformation systems are categorized as
non-cropland or developed area. In some agricultural land parcel identification
systems, non-cropland parcels were even totally discarded to save storage and
increase access and process speed.
The attributes of agricultural land parcel not only clearly describe the location,
boundary, and ownerships but also contain agricultural statistics such as crop type
and soil type. For example, crop rotation is a common way to increase productivity
that could harm soil health (Moudon 2000). Monitoring cropland at the parcel level
is necessary to evaluate the health condition of the land (Moudon 2000). Such kind
of information do not exist for other types of parcel but only belong to agricultural
land parcels (Fig. 9.1).
9.2.3 Techniques to Identify Land Parcel
Accurate land information is significant to both private owners and public society
(National Research Council 2007). As a result, land parcel information need to be
accurate and reliable both spatially and temporally (Library of Congress 2011).
However, significant effort is needed to continuously provide such land parcel
data. In addition, accurate land parcel data is not only expensive but also hard to
access. The techniques of land parcel identification, which have benefited from the
development of science and technologies, improved significantly in the last decades.
Land survey is one of the earliest but most reliable way of identifying land parcel
for thousands of years. Prior to the Industrial Revolution, accuracy was important
