TODO\n\n当前版本足够 MapboxGL.js 使用，但仍然有新功能未开发，留待以后扩展功能，初步拟定待扩展功能如下：\n\n- 大数据量的dem tif改用分块读取分块处理\n- 扩展 gdal 驱动，使其支持 webp，直接生成 webp 格式的切片\n- 重构核心模块，解耦，扩展使其支持生成 CesiumJS 支持的地形切片格式\n\n欢迎参与贡献，包括但不限于文档、功能扩展、性能优化！\n\n# 5. 安装问题\n\n## 5.1 c++编译环境问题\n\n由于node-gdal、node-gdal-next或node-gdal-async都会内置编译安装一个gdal，编译是需要依赖c++环境的，在win上常出现问题如下：\n```bash\nnpm ERR! gyp ERR! stack Error: Could not find any Visual Studio installation to use\n```\n如果用户未安装vs c++环境，请最好安装下vs c++编译环境。\n如果用户已经安装了vs，例如vs2022仍提示找不到，配置如下：\n```bash\n# 配置npm的msvs版本号，例如安装了vs 2022\nnpm config set msvs_version 2022\n# 更新下node-gyp\nnpm install node-gyp@latest -g\n```\n## 5.2 环境变量冲突\n在node-gdal系列相关包npm安装成功后，使用过程中遇到投影操作定义就会报各种错误，典型错误如下：\n```\nconst srs= gdal.SpatialReference.fromProj4('+init=epsg:4326'); ^ Error: Corrupt Data\n```\n主要原因是win上各种软件包都会内置安装，环境变量冲突导致。\n\n例如，用户安装了PostGIS，会内置安装proj,geos,gdal并自动生成proj_lib的环境变量。\n```\nPROJ_LIB=C:\\Program Files\\PostgreSQL\\14\\share\\contrib\\postgis-3.1\\proj\n```\n当安装node-gdal-next或noe-gdal-async时，内置的proj和proj.db由于冲突不能生效，就会在使用过程中报各种错误。\n依此类推，如果用户安装了独立的GDAL，又有内置的proj，geos和环境变量也会有这种问题。\n解决办法：从系统环境变量中删除这些冲突的环境变量重启机器即可。\n\n## 5.3 最好的办法\n使用本机已编译好的gdal编译binding下node的gdal环境：\n```\nnpm install gdal-next --build-from-source --shared_gdal\n\nnpm install gdal-async --build-from-source --shared_gdal\n```\n\n这样，node的gdal环境可以和本机的gdal环境一致，能使用更多的驱动例如webp，内置驱动是没有的。\n这种操作可以让公用软件装一次，不会产生更多的冲突，linux上很方便。但由于windows上都不是源码编译，从.exe安装，因此不太适用。该操作适合c++编译环境熟悉的高级用户可定制安装多项扩展。\n\n\n# 6. 知识补充\n\n## 6.1. 参考资料\n\n- [GitHub - tilezen/joerd - terrarium](https://github.com/tilezen/joerd/blob/master/docs/formats.md#terrarium)\n\n- [MapboxDocs - raster-dem](https://docs.mapbox.com/data/tilesets/reference/mapbox-terrain-dem-v1/)\n\n## 6.2. 编解码差异\n\n`mapbox` 和 `terrarium` 都将高程值编码成 RGB 数组存储，下面以简单的编解码函数说明两种编码格式的差异。\n\nMapboxGL：\n\n```typescript\nfunction mapboxEncode(height: number) {\n const value = Math.floor((height + 10000) * 10);\n const r = value >> 16;\n const g = value >> 8 & 0x0000FF;\n const b = value & 0x0000FF;\n return [r, g, b];\n}\n\nfunction mapboxDecode(\n color: [number, number, number]\n) {\n return -10000 + ((color[0] * 256 * 256 + color[1] * 256 + color[2]) * 0.1);\n}\n```\n\nterrarium：\n\n```typescript\nfunction terrariumEncode(height: number) {\n height += 32768;\n const r = Math.floor(height / 256.0);\n const g = Math.floor(height % 256);\n const b = Math.floor((height - Math.floor(height)) * 256.0);\n return [r, g, b];\n}\n\nfunction terrariumDecode(\n color: [number, number, number]\n) {\n return (color[0] * 256 + color[1] + color[2] / 256.0) - 32768;\n}\n```\n\n对于 cesium 的地形编码和解码：\n\n```typescript\n// 每个点像素值是 int16\nfunction cesiumEncode(height: number) {\n return Math.floor((height + 1000) / 0.2);\n}\n\nfunction cesiumDecode(pixel: number){\n return (pixel * 0.2) - 1000;\n}\n```\n" }, { "path": "bin/dem2terrain.js", "content": "#!/usr/bin/env node\nconst { program } = require('commander');\nconst main = require('../index');\nconst path = require('path');\nconst version = require('../package.json').version;\n\n// node版本检查\nif (+process.version.substring(1, 3) < 16) {\n console.error(`node版本>=16，当前版本 ${process.version}`);\n process.exit();\n}\n// { version } from 'node:process';\nprogram.name('dem2terrain')\n .description('使用 GDAL 制作地形瓦片，支持 mapbox 和 terrarium 两种编码输出格式，当前仅输出 PNG 容器格式。')\n .version(version, '-v, --version', '当前版本')\n .helpOption('-h, --help', '帮助');\n\n// --- 配置可选参数\nprogram\n .option('-i, --input ', '<必填> 输入 tif 格式的 DEM 文件路径，支持相对路径')\n .option('-o, --output ', '<必填> 输出目录，支持相对路径')\n .option('-f, --configFile ', '<可选> 通过配置文件执行任务，输入绝对路径，可参考配置模板')\n .option('-r, --resampling ', `<可选> 构建影像金字塔或重投影时设置重采样策略，默认3，1:AVERAGE|\n 2:BILINEAR|3:CUBIC|\n 4:CUBICSPLINE|5:LANCZOS|\n 6:MODE|7:NEAREST`, 3)\n .option('-g, --epsg ', '<可选> Tile适用坐标系，3857 | 4490 | 4326', 3857)\n .option('-c, --clean ', '<可选> 是否清空输出目录，0 | 1', 0)\n .option('-z, --zoom ', '<可选> 指定瓦片的等级生成范围。例如，想生成 7 ~ 12 级的瓦片，则输入 -z 7-12', '5-14')\n .option('-e, --encoding ', '<可选> 指定瓦片的数据编码规则（mapbox 或 terrarium）', 'mapbox')\n .option('-b, --baseHeight ', '<可选> 基准高度，默认0', 0);\n\n// --- 解析参数\nprogram.parse();\n\nconst options = program.opts();\n// 判别是否是配置文件还是命令行配置\nlet params;\nif (options['configFile'])\n params = require(options['configFile']);\nelse\n params = options;\nconst inputDem = params['input'];\nconst outputDir = params['output'];\nif (inputDem === undefined || outputDir === undefined) {\n console.log('参数缺失: 输入文件路径或输出目录必填');\n process.exit();\n}\n\nconst encoding = params['encoding'];\nconst epsg = Number(params['epsg']);\nconst isClean = Number(params['clean']);\nlet baseHeight = Number(params['baseHeight']);\nif (isNaN(baseHeight))\n baseHeight = 0;\nlet zoom = params['zoom'];\nzoom = zoom.split('-');\nconst minZoom = Number(zoom[0]);\nconst maxZoom = Number(zoom[1]);\n\nif (isNaN(minZoom) || isNaN(maxZoom)) {\n console.log(`参数 -zoom: ${zoom} 错误，应为整数`);\n process.exit();\n}\nif (minZoom >= maxZoom) {\n console.log(`参数 -zoom: ${zoom} 错误：最小级别: ${minZoom} 应小于最大级别: ${maxZoom}`);\n process.exit();\n}\n\nconst inputAbsolutePath = path.isAbsolute(inputDem) ? inputDem : path.resolve(process.cwd(), inputDem);\nconst outFileAbsolutePath = path.isAbsolute(outputDir) ? outputDir : path.resolve(process.cwd(), outputDir);\n\nconst logMsg = `\\n>> 开始转换...\n- 输入文件: ${inputAbsolutePath}\n- 输出路径: ${outFileAbsolutePath}\n- Tile适用坐标系: EPSG:${epsg}\n- 瓦片编码: ${encoding === 'mapbox' ?
