使用 diewald_shapeFileReader 完成 ArcGIS shp文件自动转换为geojson

diewald_shapeFileReader 是 Thomas Diewald 写的一个关于ArcGIS shp文件的读取工具。主要是针对于 shx dbf shp 三个文件。看了很多转换的部分都是在线转换的。

1 读取文件

// path 为所在文件夹的路径
// name 为不带后缀的文件名
ShapeFile shapeFile = new ShapeFile(path, name).READ();

2 获取属性字段

// 获取属性表字段个数
int fieldCount = shapeFile.getDBF_fieldCount();
// 获取属性表记录条数
int dataCount = shapeFile.getDBF_recordCount();

// 获取属性信息
// 需要注意的：ISO-8859-1 字符是shapefile读取工具设置的编码
// 但是arcgis是以gbk编码字符存储的，不过这个编码也不是固定的，有的时候utf-8不乱码，有时候gbk不乱码，根据实际情况来
fieldName = new String(fieldName.getBytes("ISO-8859-1"), "utf-8"); // 字段名
fieldName = (fieldName != null) ? fieldName.trim() : fieldName; // 剔除空白
String fieldValue = shapeFile.getDBF_record(i, j); // 字段对应的值
fieldValue = new String(fieldValue.getBytes("ISO-8859-1"), "utf-8");
fieldValue = (fieldValue != null) ? fieldValue.trim() : fieldValue; // 剔除空白

3 获取图形类型

// 获取图形类型====（点、线、面）
ShpShape.Type shapeType = shapeFile.getSHP_shapeType();

4 点

if (shapeType.isTypeOfPoint()) { // 单点
ArrayList<Object> pointShapes = shapeFile.getSHP_shape();
for (int i = 0; i < pointShapes.size(); i++) {
ShpPoint point = (ShpPoint) pointShapes.get(i);
GeoFeature feature = new GeoFeature();
GeoGeometryPoint geoPoint = new GeoGeometryPoint();
double[] xyz = point.getPoint();
double[] xy = new double[]{xyz[0], xyz[1]}; // 去掉z坐标，只保留xy
geoPoint.setCoordinates(xy);
feature.setGeometry(geoPoint);
feature.setProperties(properties.get(i));
collection.getFeatures().add(feature);
}
}

5 多点

if (shapeType.isTypeOfMultiPoint()) { // 多点
ArrayList<Object> pointsShapes = shapeFile.getSHP_shape();
for (int i = 0; i < pointsShapes.size(); i++) {
ShpMultiPoint points = (ShpMultiPoint) pointsShapes.get(i);
GeoFeature feature = new GeoFeature();
GeoGeometryMultiPoint geoMultiPoint = new GeoGeometryMultiPoint();
double[][] num_xyz = points.getPoints();
List<double[]> num_xy = new ArrayList<>(); // 去掉z坐标，只保留xy
for (int n = 0; n < num_xyz.length; n++) {
num_xy.add(new double[]{num_xyz
[0], num_xyz
[1]});
}
geoMultiPoint.setCoordinates(num_xy);
feature.setGeometry(geoMultiPoint);
feature.setProperties(properties.get(i));
collection.getFeatures().add(feature);
}

6 线

if (shapeType.isTypeOfPolyLine()) { // 线
ArrayList<Object> lineShapes = shapeFile.getSHP_shape();
for (int i = 0; i < lineShapes.size(); i++) {
ShpPolyLine line = (ShpPolyLine) lineShapes.get(i);
GeoFeature feature = new GeoFeature();
if (line.getNumberOfParts() == 1) { // 单线
GeoGeometryLineString geoLine = new GeoGeometryLineString();
double[][] num_xyz = line.getPoints(); //[number of points][x,y,z]
List<double[]> num_xy = new ArrayList<>(); // 去掉z坐标，只保留xy
for (int n = 0; n < num_xyz.length; n++) {
num_xy.add(new double[]{num_xyz
[0], num_xyz
[1]});
}
geoLine.setCoordinates(num_xy);
feature.setGeometry(geoLine);
feature.setProperties(properties.get(i));
collection.getFeatures().add(feature);
} else { // 多线
GeoGeometryMultiLineString geoMultiLine = new GeoGeometryMultiLineString();
double[][][] line_num_xyz = line.getPointsAs3DArray(); // [number of polylines][number of points per polyline][x, y, z, m]
List<List<double[]>> line_num_xy = new ArrayList<>(); // 去掉z坐标，只保留xy
for (int n = 0; n < line_num_xyz.length; n++) {
List<double[]> line_points = new ArrayList<>();
for (int k = 0; k < line_num_xyz
.length; k++) {
line_points.add(new double[]{line_num_xyz
[k][0], line_num_xyz
[k][1]});
}
line_num_xy.add(line_points);
}
geoMultiLine.setCoordinates(line_num_xy);
feature.setGeometry(geoMultiLine);
feature.setProperties(properties.get(i));
collection.getFeatures().add(feature);
}
}
}

7 面

if (shapeType.isTypeOfPolygon()) { //
99d3
面
ArrayList<Object> polygonShapes = shapeFile.getSHP_shape();
for (int i = 0; i < polygonShapes.size(); i++) {
ShpPolygon polygon = (ShpPolygon) polygonShapes.get(i);
GeoFeature feature = new GeoFeature();
if (polygon.getNumberOfParts() == 1) { // 单面
GeoGeometryPolygon geoPolygon = new GeoGeometryPolygon();
double[][] num_xyz = polygon.getPoints(); // [number of points][x,y,z]
List<List<double[]>> num_xy = new ArrayList<>();
List<double[]> xy = new ArrayList<>();
for (int k = 0; k < num_xyz.length; k++) {
xy.add(new double[]{num_xyz[k][0], num_xyz[k][1]});
}
num_xy.add(xy);
geoPolygon.setCoordinates(num_xy);
feature.setGeometry(geoPolygon);
feature.setProperties(properties.get(i));
collection.getFeatures().add(feature);
} else { // 多面
GeoGeometryMultiPolygon geoMutliPolygon = new GeoGeometryMultiPolygon();
double[][][] poly_num_xyz = polygon.getPointsAs3DArray();
List<List<List<double[]>>> poly_num_xys = new ArrayList<>();
List<List<double[]>> poly_num_xy = new ArrayList<>(); // 去掉z坐标，只保留xy
for (int n = 0; n < poly_num_xyz.length; n++) {
List<double[]> poly_points = new ArrayList<>();
for (int k = 0; k < poly_num_xyz
.length; k++) {
poly_points.add(new double[]{poly_num_xyz
[k][0], poly_num_xyz
[k][1]});
}
poly_num_xy.add(poly_points);
}
poly_num_xys.add(poly_num_xy);
geoMutliPolygon.setCoordinates(poly_num_xys);
feature.setGeometry(geoMutliPolygon);
feature.setProperties(properties.get(i));
collection.getFeatures().add(feature);
}
}
}

8 使用



使用java -jar 命令执行jar包

第一个参数为shp文件所在路径地址

第二个参数为文件名称



执行完毕后，会在shp文件所在路径下生成一个同样名字的json文件，就可以直接使用了。
