Open Source를 이용한 상용 GeoProcessing Engine 구현 2012.10.12 김기웅 (socoooooool@gmail.com)
이민파 (mapplus@gmail.com) 개발배경 아키텍쳐 주요기능 활용사례 우리는 왜 오픈소스로 개발 했는가? 인력, 시간

호환성, 확장성, 안정성

프리 플랫폼 (Java 지원)

클라이언트에 대한 엔진독립성

OGC 표준 서비스 (WMS, WFS, WCS, WPS) 지원 JTS - JTS Topology Suite
Geometry Engine
LGPL License
API for vector-based 2D geometry
Full implementation of OGC Simple Features Spec
100% Java
Fast, robust

http://sourceforge.net/projects/jts-topo-suite/ Open Source GIS – JTS Topology Suite GeoTools – LGPL License
GeoTools is an open source (LGPL) Java code library which provides standards compliant methods for the manipulation of geospatial data

Implemented Standards
OGC Style Layer Descriptor / Symbology Encoding data structures and rendering engine
OGC General Feature Model including Simple Feature support
OGC Grid Coverage representation of raster information
OGC Filter and Common Constraint Language (CQL)
Clients for Web Feature Service, Web Map Service and experimental support for Web Process Service
ISO 19107 Geometry

Web
GeoServer
OpenGeo Suite
52N WPS

Desktop
uDig
gvSIG
OpenJUMP Open Source GIS – Applications Architecture 약 120여 개의 KOPSS Open API 분석 프로세스 지원
공간통계, 래스터, 벡터 분석 등 약 100여 개의 확장 분석 프로세스 탑재 Key Features – GeoProcessing processes Key Features - Processes Key Features - Processes Built-in 지원: PostGIS, SpatiaLite, Oracle Spatial, ArcSDE, MySQL
확장: Altibase, Tibero, Kairos, Zeus, 데이터베이스간 migration Key Features – Data Store Sphinx 기반 Online 도움말 Key Features – Online Documentation GeoServer 기반 WPS 지원 Key Features – WPS Support 국토공간계획지원체계(KOPSS) – Web Client 활용사례 – GXT for GeoServer Toolbox Plug-in for uDig Desktop 활용사례 – GXT for uDig 프로세스 파라미터에 따른 자동 UI 구성
BoundigBox : xmin, ymin, xmax, ymax, srs
FeatureCollection , GridCoverage - 콤보박스
Geometry – WKT 입력
SpatialReferenceSystem: text + button
Filter – CQL 입력

분석결과 처리
FeatureCollection, GridCoverage, Geometry는 레이어로 등록
텍스트로 표현 가능한 결과(WPS에서 XML)에 대해서는 OutputIO 확장 예정. Ex)HTML….

향후 계획
파라미터 relation 확장 및 Modeler
Remote resources 활용사례 - 기타 GXT for uDig Demo
