Abstract

Ocean leisure sports have recently emerged as one of so-called blue ocean industries. They are sensitive to diverse environmental conditions such as current, temperature, and salinity, which can increase needs of forecasting data as well as in-situ observations for the ocean. In this context, a Web-based geovisualization system for coastal information produced by model forecasts was implemented for use in supporting various ocean activities. First, FVCOM(Finite Volume Coastal Ocean Model) was selected as a forecasting model, and its data was preprocessed by a spatial interpolation and sampling library. The interpolated raster data for water surface elevation, temperature, and salinity were stored in image files, and the vector data for currents including speed and direction were imported into a distributed DBMS(Database Management System). Web services in REST(Representational State Transfer) API(Application Programming Interface) were composed using Spring Framework and integrated with desktop and mobile applications developed on the basis of hybrid structure, which can realize a cross-platform environment for geovisualization.

최근 해양레포츠 산업이 블루오션으로 떠오르고 있는데, 해양레포츠는 조류, 수온, 염도 등과 같은 다양한 환경조건에 영향을 받기 때문에 관측자료 뿐만 아니라 모델 예측자료도 매우 필요한 정보이다. 본 연구에서는 연안해양모델인 FVCOM(Finite Volume Coastal Ocean Model)에서 산출된 예측자료를 웹 및 스마트폰을 통해 제공하는 시각화시스템을 구현하였다. 이를 위하여 FVCOM 자료에 내삽과 샘플링 등의 전처리를 하여, 조위, 수온, 염도의 래스터 이미지와 조류(유속, 유향)의 벡터 데이터베이스를 구축하였고, 스프링 프레임워크(Spring Framework)를 활용하여 REST(Representational State Transfer) 기반의 API(Application Programming Interface)를 제공하는 웹서비스를 구축하였다. 또한 데이터베이스 자료를 데스크톱 및 이기종의 스마트폰에 탑재시킴으로써 크로스플랫폼(cross-platform) 시각화 환경을 실현하였다.
