Question

我很长时间坚持这个，请帮助我。请让我知道我们怎么做在geotools地图上添加一个Mapinfo文件图层请帮忙

  OGRDataStoreFactory factory = new JniOGRDataStoreFactory();

  Map<String, String> connectionParams = new HashMap<String, String>();
  connectionParams.put("DriverName", "MapInfo File");
  connectionParams.put("DatasourceName",
               "C:\\Users\\Varun\\Desktop\\Test\\export\\MS1_Longcall0608143822_001.tab");
  DataStore store = factory.createDataStore(connectionParams);
  SimpleFeatureSource featureSource = store.getFeatureSource("MS1_Longcall0608143822_001");
  MapContent map = new MapContent();
  map.setTitle("Quickstart");


  Style style = SLD.createSimpleStyle(featureSource.getSchema());
  Layer layer = new FeatureLayer(featureSource, style);         
  map.addLayer(layer);       // Now display the map
  JMapFrame.showMap(map);

GeoTools无法找到您的GDAL库。您需要检查几件事。从数据存储页面：

您需要使用Java支持编译GDAL / OGR的安装才能使用此模块。

安装GDAL会出现这种情况吗？

OGR DataStore确实需要GDAL / OGR本机库。安装后，您需要将位置添加到Windows上的PATH，Mac上的DYLD_LIBRARY_PATH和Linux上的LD_LIBRARY_PATH。如果您使用gt-ogr-bridj并且dll / dylib / so文件未命名为gdal，则需要设置GDAL_LIBRARY_NAME。通常它类似于gdal10，具体取决于您安装的GDAL版本。在运行程序时，您还必须将java.library.path设置为GDAL的位置。

您是否设置了这些环境变量？
