需要提供测试样例数据

forEachHeightBuffer(heightBuffer, encode)时heightBuffer未定义。当前2.2.7版本支持以下数据类型： if (dataType === 'Int8' || dataType == gdal.GDT_Byte) { heightBuffer = new Uint8Array(writeinfo.wxsize * writeinfo.wysize); dataType = gdal.GDT_Byte; } else if (dataType === gdal.GDT_Int16) heightBuffer = new Int16Array(writeinfo.wxsize * writeinfo.wysize); else if (dataType === gdal.GDT_Float32) heightBuffer = new Float32Array(writeinfo.wxsize * writeinfo.wysize);，如果dem的类型不是如下判断，将为空对象。
