스마트폰기반의 TS 측량 지원시스템 개발 - 트래버스 및 현황 측량을 중심으로

Abstract

The advancement of smartphone has made it possible for all people to use spatial information service easily. It's required to build correct spatial information in order to use spatial information service easily. Totalstation surveying to build spatial information has been conducted on site by technicians compared to satellite images and aerial photogrammetry. The desktop PC is cumbersome to be carried, and Notebook and tablet PC are easy to be carried but they are inconvenient to be connected with surveying instruments. Therefore, this study is about surveying method combined with PDA that is a portable terminal in order to solve above problems. However, this surveying method combined with PDA needs additional cable such as RS-232C cable for connecting with totalstation and potable terminal and moreover, it's only possible to store numerical topographic map in order to check surveying data and outcomes after surveying data is transferred to a computer. There have not been researches and methods to solve these problems. It's necessary to find totalstation surveying support system under smart phone environment well matched with current situation. To solve this problem, this research developed a system with Android app to support traverse and current surveying by smartphone based totalstation. The app developed by this research made it possible to send data in a way that connects totalstation and smartphone via Bluetooth, and the transferred data is stored into SQLite Database so that it can be directly processed in the field. The app made it possible to check coordinates by mapping the surveying data with internet map services such as Google map, Naver map and Daum map. Measured outcomes in the app can be sent by text format while the coordinate of the surveyed points can be sent by KML file. The proposed app is expected to greatly contribute to enhancement of operational capability for total station and convenience for users.
