Currently, start of the operation US GPS, the Russian Glonass, European Galileo, the Chinese Compass satellites for positioning are celebrating a true GNSS (Global Navigation Satellite System) generation. Korea is building advanced infrastructure such as a national network consisting of CORS (Continuously Operating Reference Station), VRS service for real-time precise positioning and perform continuous upgrading. However, the acquisition of geospatial information using the national infrastructure requires many steps and high dependence on foreign software part in this process. This study contributes to advanced construction technology of geospatial information by design of realtime GNSS surveying system. As a results, it has designed the surveying software that can effectively positioning realtime. Designed realtime surveying software can utilized in various fields.

The necessity of a short period of software development with lower cost came out. The reason of making the component based development is that it can improve the software development , productivity maintenance , and software quality innovatively. Following these advantages of component based application development methods, we found the COM based components effective to Window platform in the satellite surveying. In this paper, we can obtain many precious engineering experiences. Software system development and maintenance will take much shorter time with higher reusability if satellite surveying system is constructed with component extraction proposed by us.

Research that establish new cadastral survey model that use GPS to introduce GPS observation technique in cadastral survey and research that develop connection technologies are gone abuzz. The purpose of this research is to keep in step in such trend and grasp present condition and performance of surveying connection to common use GPS data processing software, and analyze data processing algorithm, and develop suitable GPS data processing software in our real condition regarding GPS data processing and result of control point calculation. This research studies analysis common use software and error occurrence by data processing method that college and company have. Also, It analyzes algorithm that is applied to existing GPS data processing software. After that we study algorithm that is most suitable with cadastral survey and then develop cadastral survey calculation software for new cadastral control points

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.

A software package for the basic computations in land-surveying is developed. The least square adjustments for the horizontal and vertical control networks are the main functions of the program, with various computational functions for the traverses, intersections and resections. The coordinate transformations are included as well. The coordinates of the stations and the observations are stored in the databases so that they can be used in any stage of the software process. An editor to manipulate the database is also accomplished.

On the basis of comprehensive analysis and summarization of the image fusion algorithms provided by PCI Geomatica software, deficiencies in image fusion processing functions of this software are put forwarded in this paper. This limitation could be improved by further developing PCI Geomatica on the user’ side. Five effective algorithms could be added into PCI Geomatica. In this paper, the detailed description of how to customize and further develop PCI Geomatica by using Microsoft Visual C++ 6.0, PCI SDK Kit and GDB technique is also given. Through this way, the remote sensing imagery fusion functions of PCI Geomatica software can be extended.

This study analyzed and compared the results of baseline processing by Bernese GPS software packages and by GPSurvey software respectively. Then it investigated considerations when very long baselines are processed. There are rarely differences which is accompanied by baseline length when it is processed by Bernese GPS software but there are somewhat differences in proportion to the baseline length when it is processed by GPSurvey software.

There are many GPS software packages and this document compared the result of baseline processing by Bernese GPS software with it by GPSurvey software. This paper also analyzed the results and investigated considerations when very long baselines are processed. There are rarely differences which is accompanied by baseline distance when it is processed by Bernese GPS software but there are somewhat differences which is accompanied by baseline distance when it is processed by GPSurvey software.

This study is aimed to research the management methodology for the process of GIS database construction. In general, used methodologies are made for the purpose of application program development. And the methodologies reflected GIS characteristics are also applied for GIS software development. But the software methodologies are never introduced to construction of GIS database. In this study, various common methodologies are investigated and analyzed, and the methodology which include the characteristic of GIS database construction process as work steps and detail paths is developed and suggested.
