Surveying and GIS have increasingly contributed to improve the quality of humane life through the development of its technology. While the surveying professions are now experiencing the crisis of identity. In this paper, we aim to study the concepts and presence of newly used terminologies, present state and future vision of surveying and GIS in Korea. To cope with various surveying consumers for expanding the market and their demands, enhancement of educational system, complement of laws legal system, construction of cooperative system in business are basically required.

There has been a need for replacing human labors with a robot in such dangerous and hard jobs of various construction sites. For that reason, many researches have been made about the high quality robot, which performs its duty instead of human labors. This study is about auto surveying system development based on VRS-GPS which enables autodriving in dangerous areas where it's difficult for humans to measure directly. This study is about the auto-surveying system development, based on VRS-GPS, which enables auto-drive in dangerous areas, whereas difficult for humans to measure directly. The GPS is made with GRXI and SHC250 controllers of the SOKKIA company. The auto surveying system is composed of DPS module, geomagnetism sensor, bluetooth, gimbals, IMU, etc to automatic drive via enter into a route of position. The developed auto surveying system has installed the carmeras for front and vertical axis as well as systems to grasp situation of surveying with smartphone in real time. The result from analysed RMSE of auto surveying system and VRS-GPS surveying is 0.0169m of X-axis and 0.0246m of Y-axis.

The field of land surveying is changing dramatically due to the way data is processed, analyzed and presented. Also, there is a growing demand for digital spatial information, coming primarily from the GIS (Geographical Information System) user community. Such a demand has created a strong development potential for a new land surveying software. An overview of the development and capabilities of a land surveying software platform based on the Windows system, SurveyingMap, is presented. Among its many features, SurveyingMap provides a lot of adaptability for networks adjustment, geodetic and plane coordinates transformation, contouring, sectioning, DTM (Digital Terrain Model) generation, and large scale mapping applications. The system output is compatible with well known computer aided drafting (CAD) /GIS packages to expand its scope of applications. SurveyingMap is also suitable for non-technical users due to the user-friendly graphic user interface. The system could be used in engineering, architecture, GIS, and academic teaching and research, among other fields. Two applications of SurveyingMap, extension of field control and large scale mapping, for the case study area are established. The results demonstrate that the system is adaptable and reasonably priced for use by college and university students.

The current cadastral business is being operated by conversion to a digital cadastral management system through computerized registers (land register and forest land register) and maps (cadastral map and forest cadastral map). Digital surveying methods, such as GPS surveying and electronic plane table surveying, are also used for cadastral surveying. At present, fees for cadastral surveying are calculated based on a standard pursuant to the Construction Standard Production Unit System and an announcement by the Ministry of Land, Infrastructure, and Transportation. In many cases, however, the cadastral surveying fee system announced at present fail to apply the digitalized environment depending on the item. This study sought to analyze the cadastral surveying fee system that requires improvement in the rapidly changing digital cadastral management environment, and to prepare a basis to establish a cadastral surveying fee system suitable to the digital environment by suggesting an improvement method for such system. As a result of the study, the following suggestions were made: a method of changing to terms suitable to the digital environment based on the current status analysis; preparation of a new estimation system regarding new estimation items; and re-survey of an estimation system of cadastral confirmation survey and preparation of an estimation system.

In this paper, development of automation system for real time cadastral surveying and mapping is studied. This system is composed of interface between pc and GPS receiver, input-output-store of positioning information by RTK-GPS surveying. Also coordinates of surveying is displayed on CAD. As a results of this application on the field, transformed coordinates of points are displayed on the map at the real time as surveying. This system is applied to construct coordinate information for a parcel of land, and this could be specially used to realize the information of boundary points in the field.

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 rapid development of Kuala Lumpur has seen numerous new and high-rise buildings introducing Building Automation System (BAS). Whilst effective application of Knowledge Management (KM) within BAS is the pre-requisite for the achievement of optimum BAS performance, there has been little research undertaken to investigate if have been the case. This paper presents a research undertaken to get a view of how KM applies in BAS in six (6) selected case-study buildings in Kuala Lumpur, all operating with the 'one-system' M&E workstation control BAS. The emergent findings positively suggest that adequate KM approaches were employed within their BAS management processes, but further studies would be necessary to determine the extent of their application and effectiveness.

This study aims to suggest efficient setting up of GPS (Global Positioning System) for cadastral surveying. In order to perform it effectively, worldly used modern surveying technology GPS introduced. In a practical analysis, GPS observation had been performed in the research area and the results had been compared and analysed with the results of Total Station. As a results, it is shown that GPS is more efficient rather than current surveying method in terms of time, cost and economy. The results of GPS surveying were included in the scope of error tolerance, being accepted by cadastral laws, showing high accuracy of GPS surveying method. With the results of analysis, how to application of GPS for cadastral surveying was suggested.

This study aims to study the present situation of our national surveying system, in fields such as professional surveyor system, the surveying industry, the consultancy pricing system. The problems are identified to present an improvement plan for the system. The professional surveyor system was compared to other systems in the Asia Zone and the surveying industry related laws and regulations, were compared with those of foreign countries as well as with the regulations of the architectural industry. The improvements suggested include upgrading of surveying technology and of surveying personnel, increase investment into education and research and development. The government should support in policy upgrading such as providing aids to small scale companies and in distributing the concentrated activities in the capital city to other regional areas. Also the pricing for the surveying activities and consulting activities should he adjusted in fields such as price items, grades of surveyors and overhead costs.

GPS(Global Positioning System) surveying is an effective method using satellite measurement system and can be applied to construction of digital map of irrigation canal networks. In this study, GPS surveying method for irrigation structures was developed. A selected main canal of an irrigation district were surveyed by GPS. The obtained surveying results were corrected by post-processed DGPS (Differential Global Positioning System) and imported to GIS for the digital map construction.
