ABSTRACT: Over the past few years, government agencies at national, provincial and local levels have given much attention to the
development and implementation of land management information system (LMIS). In this paper the functions, structures, key technologies
and the methodologies of development of LMIS in China are described. By analyzing the up-to-date techniques of Web GIS and spatial
DBMS, the state and local levels of modern land management information systems are designed. To assist in elaborating the methods of
implementation of LMIS, a typical LMIS at county and state levels based on Maplnfo MapXtreme and Oracle 8i is introduced.
INTRODUCTION
Because all the procedures of land management depend on
the geo-spatial information and are related to the laws, policies
and rules, many modern techniques such as GIS/LIS, DBMS,
computer science, Intranet/Internet technology, office
automation (OA), and so forth must be applied to the
development of LMIS (Coleman and McLaughlin 1998; Zhao
1999). By use of the LMIS most of the daily work of land
management can be accomplished efficiently, safely and
successfully. Meanwhile LMIS could provide the richness of
date/information to the government agencies for the
decision-making and everyday management work. LMIS can
also provide the services to other departments of the
government agencies such as urban planning, facility
management, tax collection, and so on (Land Victoria 1997;).
China is the largest developing country in the world, and the
conflict between land use and population is very serious. It is
therefore technically difficult, but also very important socially,
economically, environmentally and politically to manage land
resources, land uses and land activities efficiently (Zhao
1995,1998).
The research and implementation of the LMIS based on the
Web GIS, Intranet/Internet technology and spatial DBMS is in
the trial stage in China. Up to now, only a few of LMISs are
developed in some local government agencies in China. The
reasons behind the difficulties of implementing the new LMIS
include the following. Firstly, due to lacking of experiences
combined with seeking to work at the level of advanced
techniques, problems in the functionalities of software
packages used for land data/information processing were
encountered. Secondly, the data was in various formats in
different systems. Thirdly, spatial data and land registration
were still largely processed by manual systems. Last, but not
the least, few LMISs had the abilities of the office automation
and were based on the technology of Web GIS.
This paper briefly describes the structures, functions and
features of the new generation of LMIS. The technical
difficulties of the development of LMIS are overviewed. To
assist in elaborating the methods of development and
implementation of LMIS, a typical LMIS based on Maplnfo
MapXtreme and Oracle 8i is summarized.
STRUCTURES AND CHARACTERISTICS OF LMIS
LMIS in China has four levels, national, provincial, city, and
county level LMIS (Zhao 1999). Each level of LMIS consists of
subsystems of cadastral management, land use planning, land
use management, document management, land use control,
land inventory, etc. And the data/information of land
management should be shared and transferred among different
levels of LMIS.
As all the other subsystems need to use the spatial and
attribute data of cadastral, the cadastral management is the
core of the LMIS. While LMIS is developed the following factors
must be considered. First, the methods to get and process
spatial data as well as attribute data, and ultimately create
databases, must be studied. Second, the data flow; workflow
and user’s requests of LMIS should be carefully analyzed. LMIS
should meet the needs of office automation (OA),
Intranet/Internet based and “without paper office in the
departments of land management. Meanwhile, the systems
should have the properties of user-friendly interfaces, and easy
to use. Moreover, as the large quantities of land
data/information, and changes to land use are very common,
some technical difficulties to develop a successful LMIS are
