java - 映射经度和纬度

Question

所以我有多个船舶对象，每艘船都存储了一系列相关的经度和纬度坐标，显示其路线。

例如。

[Longitude: 28.780815 Latitude: 60.259568
, Longitude: 28.780402 Latitude: 60.259393
, Longitude: 28.780585 Latitude: 60.259897
, Longitude: 28.78109 Latitude: 60.259785
, Longitude: 28.780408 Latitude: 60.259422
, Longitude: 28.781125 Latitude: 60.259893
, Longitude: 28.780835 Latitude: 60.259447
]

我的希望是以某种方式在 map 上绘制每艘船的坐标，以全面了解船舶的路径。
使用 java[eclipse]，我希望创建坐标的图形映射，但在尝试找到一个好的库/工具来执行此操作时遇到问题。

尝试 kml 文件。

BufferedWriter out = new BufferedWriter(fstream); 
                            out.write("<kml>"); 
                            out.write("<Folder>");

                            out.write("<Placemark>");
                            out.write("<name>"+entry.getKey()+"</name>");
                            out.write("<LineString>");
                            out.write("<extrude>1</extrude>"); 
                            out.write("<tessellate>1</tessellate>");
                            out.write("<altitudeMode>clampToGround</altitudeMode>");
                            out.write("<coordinates>");
                            for(int i=0; i<entry.getValue().getCoordinates().size(); i++){ //path creation 
                                out.write(entry.getValue().getCoordinates().get(i).getLongitude()+","+
                                        entry.getValue().getCoordinates().get(i).getLatitude()+" ");
                            }
                            out.write("</coordinates>");
                            out.write("</LineString>");
                            out.write("</Placemark>");

                            for(int j=0; j<entry.getValue().getCoordinates().size(); j++){ //point creation 
                                out.write("<Placemark>");
                                out.write("<name>"+entry.getValue().getCoordinates().get(j).coordinates()+"</name>");
                                out.write("<tessellate>1</tessellate>");
                                out.write("<altitudeMode>clampToGround</altitudeMode>");
                                out.write("<Point>");
                                out.write("<coordinates>");
                                out.write(entry.getValue().getCoordinates().get(j).getLongitude()+","+
                                        entry.getValue().getCoordinates().get(j).getLatitude());
                                out.write("</coordinates>");
                                out.write("</Point>");
                                out.write("</Placemark>");
                            }

                            out.write("</Folder>");
                            out.write("</kml>");
                            out.close();
                        }
