416 错误（范围无法满足）

Question

检查 Chrome 的控制台，会显示以下与 GeoTIFF（山体阴影）相关的错误消息

416 Range Not Satisfiable

，其中包含概述，并按此 OpenLayers 示例中的说明进行显示。尽管这个GeoTIFF在QGIS等GIS软件中显示良好，但在OpenLayers中却没有出现，这里是控制台输出：

其 *.ovr 文件是使用以下命令创建的：

gdaladdo $tif -r lanczos --config SPARSE_OK_OVERVIEW ON --config BIGTIFF_OVERVIEW YES --config GDAL_NUM_THREADS ALL_CPUS 8 16 32 64 128 256 -ro

我想知道概述文件是否有问题，至少使用的选项允许在 OpenLayers 中显示类似的 GeoTIFF。

欢迎任何提示，

Answer 1

感谢您的评论，最后解决方案是在我的 OL 目录中创建一个

.htaccess

文件并放入其中：

Header set Accept-Ranges none Request
Header unset Range

一旦准备好，416 条消息就消失了。

希望这对其他人有帮助，
