GIS-Java安装GDAL

GDAL工具下载

首先下载编译好的GDAL文件，下载地址(https://www.gisinternals.com/release.php)
这里下载的是mapserver, 编译后的二进制文件

配置

二进制文件文件解压，将 \bin 和 \bin\gdal\java 目录中的 dll 文件,复制到所使用JDK版本的
%JAVA_HOME%/jre/bin/ 目录下

Maven

	<gdal.version>3.3.0gdal.version>
    <dependency>
    	<groupId>org.gdalgroupId>
        <artifactId>gdalartifactId>
       	<version>${gdal.version}version>
    dependency>
