해당 프로젝트의 경우 windows 기반 자바 어플리케이션 또는 windows 기반 자바 기반 서버 구축 시
GDAL을 사용할 경우 OS에 설치하지 않고 프로젝트 내부에 GDAL을 적용하는 방법입니다.
spring boot 기반으로 프로젝트를 만들었구요.
github를 통해 소스코드 공개해놓았으니까
참고하실분들은 참고하셔도될꺼같네요~

직접 프로젝트에 적용하실분은 아래를 보시고 따라하시면됩니다 :)
1. GDAL 다운로드
http://www.gisinternals.com/
GISInternals Support Site
Welcome to the GISInternals Support Site This site have been created to provide daily build packages and software development kits for the GDAL and MapServer and the related projects under the terms of a free software license. The build system is maintaine
www.gisinternals.com
해당 사이트에서 MSVC 버전 별 다운로드 가능
여기에서는 GDAL 2.4.4 MSVC 2017 x64 로 다운로드받음
2. resources 폴더 안에 gdal24 이름으로 복사
3. maven 추가
<dependency>
<groupId>org.gdal</groupId>
<artifactId>gdal</artifactId>
<version>2.4.0</version>
</dependency> |
4. 프로젝트 메인 함수에 아래 소스 적용
|
