DESIGN AND IMPLEMENTATION OF MODERN LMIS
IN COUNTY AND STATE LEVEL
While a LMIS is designed and implemented, the data
(spatial and attribute) flow and workflow must be firstly studied
(Rough 1997). Then the component GIS, Web GIS technology,
GIS platforms, as well as the spatial DBMS should be deeply
researched. The logic model and the strategies of the
development of the LMIS should also be formulated. All the
subsystems of the LMIS and their functions and the whole land
management computer networks should be designed carefully.
In addition the following factors should be considered while a
LMIS is designed and developed.
(1) The methods of the integration between GIS and MIS
should be researched so that the LMIS has the
abilities of office automation (OA), spatial data
processing and management.
(2) In terms of the characteristics that land information
changes rapidly, the ways and mechanisms to
update the spatial or mapping data and the related
attribute data of LMIS should be given. So that the
LMIS always has the up-to-date data/information,
and the ways to query the historic data/information.
(3) According to the relationship and workflow of the
departments of the bureau of land management, the
levels and rights of the operators or users should be
given to assure the system to run safely and
successfully.
(4) The methods to connect the LMIS on Intranet/
Internet should be researched, so that the publics
and other departments can query the
data/information of land management. And it is the
basis for the land registration, land exchange,
information transfer and remote office on the Internet.
(5) The strategy to develop the LMIS is to develop the
low level LMIS first, then to the higher level. The
qualities and integration of the spatial and attribute
data should be controlled.
(6) The national, provincial, local and industry standards,
as well as the coding and classification should be
executed. So that the data transformation and
sharing can be successfully and smoothly finished.
On the basis of the above analysis and discussion, the
structures of the LMIS we designed for the county and city level
is shown in Figure 3.
