OgcWmtsLayer.CachePath Property
Gets or sets a directory on disk where tiles are cached.
Syntax
public System.String CachePath { get; set; }Property Value
Default: ""
A directory on disk where tiles are cached.
Remarks
If this property is specified, WMTS tiles are cached to disk. Loading a cached tile from disk is generally much faster than requesting it from the WMTS service. The cached files may be reused many times during an application run, or from one application run to another.
The cache directory can be used by several OgcWmtsLayer instances at the same time.
The amount of disk space used by the cache is controlled by the CacheSize property.
If you modify this property from application code, make sure you do it before the layer is used in your application. Once the layer has been initialized, changing this property will have no effect.
On Windows, put the disk cache on an NTFS file system if possible. When the disk cache is full, tiles that haven't been used for a long time will be removed, based on the last time the files were accessed on disk. FAT32 files systems for instance do not record file access times, so the file modification will be used instead to decide which files to remove. This is not as optimal, and may cause unnecessary regeneration of the disk files.
