Load data training - st_read(training.shp) s2 - rast(sentinel2.tif) # 2. Extract training data training_points - st_centroid(training) values - extract(s2, training_points) # 3. Combine with labels df - data.frame(values) df$class - as.factor(training$class_id) # 4. Train model set.seed(42) train_index - createDataPartition(df$class, p 0.7, list FALSE) train_data - df[train_index, ] test_data - df[-train_index, ] rf_model - randomForest(class ~ ., data train_data, ntree 100) # 5. Predict predicted - predict(s2, model rf_model) # 6. Accuracy conf_matrix - confusionMatrix(predict(rf_model, test_data), test_data$class) print(conf_matrix) # 7. Export writeRaster(predicted, classified.tif, overwrite TRUE)set.seed(42)保证可复现createDataPartition做分层抽样保证各类别比例一致predict(s2, model rf_model)直接将训练好的模型应用到整幅影像——这套流程与 SKILL.md 中的 Python 分类函数RandomForestClassifierrasterize提取训练像元互为镜像适合在 R 侧复现同一套实验。Julia 地理空间编程Julia 凭借 JIT 编译与接近 C 的性能在地统计与高性能空间计算领域快速崛起代表库是ArchGDAL.jlGDAL 绑定与GeoStats.jl地统计。ArchGDAL.jl矢量读写与几何运算using ArchGDAL using GeoInterface # Register drivers ArchGDAL.registerdrivers() do # Read shapefile data ArchGDAL.read(countries.shp) do dataset layer dataset[1] features [] for feature in layer geom ArchGDAL.getgeom(feature) push!(features, geom) end features end end # Create geometries using GeoInterface point GeoInterface.Point(-122.4, 37.7) polygon GeoInterface.Polygon([GeoInterface.LinearRing([ GeoInterface.Point(-122.5, 37.5), GeoInterface.Point(-122.3, 37.5), GeoInterface.Point(-122.3, 37.8), GeoInterface.Point(-122.5, 37.8), GeoInterface.Point(-122.5, 37.5) ])]) # Geometric operations buffered GeoInterface.buffer(point, 1000) intersection GeoInterface.intersection(poly1, poly2)ArchGDAL.read(...) do dataset ... end的 do-block 语法自动管理资源生命周期GeoInterface提供与语言无关的几何抽象使得后续的buffer、intersection等操作在 Julia 生态内可组合、可泛化。GeoStats.jl变差函数与克里金插值地统计geostatistics是 Julia 生态的强项。下面的例子走完数据地理参考 → 实验变差函数 → 理论模型拟合 → 普通克里金 → 随机模拟全流程using GeoStats using GeoStatsBase using Variography # Load point data data georef((value [1.0, 2.0, 3.0],), [Point(0.0, 0.0), Point(1.0, 0.0), Point(0.5, 1.0)]) # Experimental variogram γ variogram(EmpiricalVariogram, data, :value, maxlag 1.0) # Fit theoretical variogram γfit fit(EmpiricalVariogram, γ, SphericalVariogram) # Ordinary kriging problem OrdinaryKriging(data, :value, γfit) solution solve(problem) # Simulate simulation SimulationProblem(data, :value, SphericalVariogram, 100) result solve(simulation)georef将普通数据帧与空间坐标绑定EmpiricalVariogram计算实验变差函数SphericalVariogram拟合球形理论模型随后分别用OrdinaryKriging做确定性插值、用SimulationProblem做条件随机模拟。这可以看作是仓库 code-examples.md 中 Python 侧skgstat.Variogram与pykrige.OrdinaryKriging的 Julia 等价实现。JavaScript 地理空间编程Node.js 与浏览器JavaScript 的定位是web 化后端计算用Turf.js前端地图渲染用Leaflet二者结合可以在浏览器中完成从空间分析到交互可视化的完整闭环。Turf.js几何计算与分析// npm install turf/turf const turf require(turf/turf); // Create features const pt1 turf.point([-122.4, 37.7]); const pt2 turf.point([-122.3, 37.8]); // Distance (in kilometers) const distance turf.distance(pt1, pt2, { units: kilometers }); // Buffer const buffered turf.buffer(pt1, 5, { units: kilometers }); // Bounding box const bbox turf.bbox(buffered); // Along a line const line turf.lineString([[-122.4, 37.7], [-122.3, 37.8]]); const along turf.along(line, 2, { units: kilometers }); // Within const points turf.points([ [-122.4, 37.7], [-122.35, 37.75], [-122.3, 37.8] ]); const polygon turf.polygon([[[-122.4, 37.7], [-122.3, 37.7], [-122.3, 37.8], [-122.4, 37.8], [-122.4, 37.7]]]); const ptsWithin turf.pointsWithinPolygon(points, polygon); // Nearest point const nearest turf.nearestPoint(pt1, points); // Area const area turf.area(polygon); // square meters要点说明Turf.js 的坐标顺序是[经度, 纬度]x, y与 GeoJSON 规范一致distance、buffer的units参数支持kilometers、miles、meters等turf.area()返回平方米等价于 Python 侧 Shapely 的Point/LineString/Polygon构造与buffer/intersection等操作适合在服务端Node.js直接对 GeoJSON 做轻量空间分析。LeafletWeb 地图可视化// Initialize map const map L.map(map).setView([37.7, -122.4], 13); // Add tile layer L.tileLayer(https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png, { attribution: © OpenStreetMap contributors }).addTo(map); // Add GeoJSON layer fetch(data.geojson) .then(response response.json()) .then(data { L.geoJSON(data, { style: function(feature) { return { color: feature.properties.color }; }, onEachFeature: function(feature, layer) { layer.bindPopup(feature.properties.name); } }).addTo(map); }); // Add markers const marker L.marker([37.7, -122.4]).addTo(map); marker.bindPopup(Hello!).openPopup(); // Draw circles const circle L.circle([37.7, -122.4], { color: red, fillColor: #f03, fillOpacity: 0.5, radius: 500 }).addTo(map);注意 Leaflet 的坐标顺序是[纬度, 经度]与 Turf 相反这是 web 地图生态的常见陷阱L.geoJSON直接消费 GeoJSON 并支持按属性动态赋样式与弹窗L.circle的radius单位为米。C 地理空间编程GDAL 原生 APIGDAL/OGR 是几乎所有语言地理空间库的底层地基其 C API 适合需要极致性能、嵌入现有 C 系统的场景。#include gdal_priv.h #include ogr_api.h #include ogr_spatialref.h // Open raster GDALDataset *poDataset (GDALDataset *) GDALOpen(input.tif, GA_ReadOnly); // Get band GDALRasterBand *poBand poDataset-GetRasterBand(1); // Read data int nXSize poBand-GetXSize(); int nYSize poBand-GetYSize(); float *pafScanline (float *) CPLMalloc(sizeof(float) * nXSize); poBand-RasterIO(GF_Read, 0, 0, nXSize, 1, pafScanline, nXSize, 1, GDT_Float32, 0, 0); // Vector data GDALDataset *poDS (GDALDataset *) GDALOpenEx(roads.shp, GDAL_OF_VECTOR, NULL, NULL, NULL); OGRLayer *poLayer poDS-GetLayer(0); OGRFeature *poFeature; poLayer-ResetReading(); while ((poFeature poLayer-GetNextFeature()) ! NULL) { OGRGeometry *poGeometry poFeature-GetGeometryRef(); // Process geometry OGRFeature::DestroyFeature(poFeature); } GDALClose(poDS);关键 API 语义GDALOpen打开栅格GA_ReadOnly只读模式GetRasterBand(1)取第一个波段波段编号从 1 开始RasterIO(GF_Read, 0, 0, nXSize, 1, ...)表示读取左上角开始的nXSize × 1的扫描行GDT_Float32指定像元数据类型矢量侧用GDALOpenEx(..., GDAL_OF_VECTOR, ...)打开、GetLayer(0)取图层、GetNextFeature()遍历要素每读完一个要素必须OGRFeature::DestroyFeature释放内存所有GDALDataset*最终都要GDALClose关闭。这份 C 代码与仓库 core-libraries.md 中的 Python 侧gdal.Open / GetRasterBand / ReadAsArray一一对应读懂了 C 版本就理解了 Python 封装背后的机制。Java 地理空间编程GeoToolsGeoTools 是 Java 生态最主流的地理空间框架与 JTS 几何库深度集成广泛用于企业级 GIS 系统。import org.geotools.data.FileDataStore;
