Cadastral surveying is related to demarcating legal boundaries and areas for the sake of registering a properly on cadastral records or restoring registered boundaries on the ground. It is composed of control surveying (cadastral triangulation and supplementary control surveying) and detail surveying. Detail surveying is classified into plane table surveying by graphical cadastral map and numerical surveying by boundary point coordinates. In this study we compared the accuracy of plane table surveying with numerical surveying using Parcel Based Land Information System(PBLIS) data constructed by the cadastral map digitalization business. In conclusion the result by numerical surveying was analyzed as more accurate than the result of plane table surveying, as Root Mean Square Errors(RMSE) of graphical cadastral surveying is 0.766m and that of numerical cadastral surveying using Total Station(T/S) is 0.683m. Therefore, PBLIS data is expected to be used for surveying legal boundaries and areas in the near future.

The tasks in the cadastral field are being carried out by the aid of Parcel Based Land Information System which is equipped with both graphical and textual information acquired by the Cadastral Map Computerization Project. This have the purpose to present efficient surveying method as analyzing the accuracy about the field map We can also avoiding the drafting error caused by graphical cadastral and technical error including scale and contraction error as inverting an existing surveying system to the computer surveying system with this data.

The purpose of this study is to analyze the optimal development direction of the land management information systems in Korea. In order to produce a new LMIS model the existing model of Tulloch(1996) was evaluated. Analysis of the land management information systems(LMIS) is focused on the period of 1998 and 2001. The main results of the study are as follows: First, the government should involve GIS(Geographic Information Systems) into the e-government. Second, the KLIS(Korea Land Information Systems) is required technological and legal infrastructure for the service using optimized land management information systems as combining LMIS and PBLIS(Parcel based Land Information Systems). Third, the spatial data of the LMIS can be promoted by ensuring reliable IT environments. Forth, optimized LMIS should be revised to reflect the new technological environment and collaborative relationship between LIS and GIS boundaries and between LMIS, urban infrastructure, and related information sectors. Fifth, In terms of services LMIS is required focusing end users rather than supplier focused strategy.

As of date, the cadastral information which is the utility to be computerized have not been identical with local autonomous entities and relational groups each other and updated real-time, therefore the relation group or the academic circles carried out in many researches on a cadastral map matching, but the cadastral maps have not been even occurred the expansion and contraction so that the theory arrangement doesn't seem simple as to a cadastral map matching. As being take such reality into consideration, We have to be based on $\boxDr$construction ministry of the rules for continuous map$\boxUl$ for a continuous cadastral map with using PBLIS data; so the operators use Autodesk Map 5 which added applications and match the neat line by the identical scale, the different scale, the district boundary and the origin according to the judgement myself We have the purpose to minimize the problem as analyzing the accuracy between the parcel coordinates If the matched map and ones of moved map.

The sheetwise cadastral map data needs to become a Serial Cadastral Map (SCM) database for the promotion of the reliability of cadastral surveying, for the efficient operation of the Parcel Based Land Information System, and for the convenient use of land information as well. A large amount of money and time are required for the editing process of producing SCM DB in accordance with the $\ulcorner$Guideline for the Production of Serial Cadastral Maps$\lrcorner$ by the Ministry of Construction & Transportation if any of field surveying techniques is accompanied by. In addition, a boundary line that extends to a neat line does not meet the counterpart of the neighboring map sheet at a point. Such cases frequently occur and are much dependent upon the decisions of individuals in charge of editing or inspecting. The core processes of the research, firstly overlay SCM produced by the edition of the sheetwise cadastral maps with Autodesk Map on orthophoto images, secondly adjust the parcel boundaries which are delineated over more than one map sheet, and lastly compare the original boundary coordinates and areas with the corresponding adjusted ones and calculate root mean square errors (RMSEs). The research aims at promoting the quality of SCM by minimizing the inconsistency of parcel boundaries by means of the comparative analysis of the calculated RMSEs.

In case of topographic information construction it is most important as basemap determines the success or failure of GIS It is argument that digitizing works of basemap are divided by NGIS and PBLIS. So, it have to accompany the combination and application of cadastral information for constructing a usful basemap. In this study, we generated ortho image map using 1:5,000 aerial-photography image, present the comparative analysis for the overlay accuracy and map revision of topographic and cadastral information using ortho image map to base map. So, we present application schemes for land use, environment, and city planning field as well as union database by overlaying of image map and cadastral information.

Much efforts are being process at many ways for digitization cadastral maps that will be the base map of Parceled Based Land Information Systems. But, current digitizing systems need too much time and cost digitizing about 720,000 cadastral maps. That's way we develop new digitization system for cadastral maps by using scanning and vectorizing methods. In this paper, we treat scanner test and vectorizing program that are the most important parts of new digitization system for cadastral maps. we analyze needs of Korean Cadastral Survey Corporation, and discuss algorithms and functions of developed programs. Using newly developed scanner test program, user could test various scanners, and use inexpensive scanner if it satisfy the accuracy needed. And vectorizing program will reduce much time and cost, because it is designed and customized practically to he adequate to cadastral maps and to improve work speed, accuracy and usage.

The land informatization methodology is the system development methodology that can be applied to the land information system to construct, manage and use the land information. Therefore, understanding of development methodology of information system and special conditions regarding the land informatization is very important. In order to enhance the understanding of land informatization, we tried various analyses on the previous land information systems developed in KOREA(PBLIS, LMIS, KLIS, KRAS) first. Then, we make a basic system development methodology to fit the land information reference model based on EA(Enterprise Architecture) and components based system. In addition, we investigate various problems or issues that occurred during the process of 30years' experience in KOREA land informatization. At last, we construct the detailed land informatization methodology which was added the method how to tasks to be carried out in each stage to solve those issues. It is the unique land informatization methodology having the most of the distinct characteristics of land information.
