Hi,
Tile-based maps are provided in a predefined tileset. In the case of
Google or OSM, for example, this is usually in EPSG 3857 and is defined
in a grid with corresponding resolutions for the different zoom levels
(always based on an extent):
https://mapserver.org/mapcache/config.html#preconfigured-grids
A WMS is usually used as the data source.
Of course, you can also do this for self-defined tilesets with other
resolutions and extents, as in the case of the Korean institute.
With MS4W and the Mapcache software it contains, you can define and
create such a tileset yourself.

Hello everyone.!
Good morning.
I'm Choi and I'm Korean.
I'm trying to load and manage a map.
1. I found mapwingis for C#
2. I found video for sample
https://www.youtube.com/watch?v=mBu9XgrfZfM
In this video, he gets map images with SAS.planet program and
supplies maps with ms4w.
After, he loaded the maps in C# project with axmap.
3. I did the sample and it works well.
4. It will take about 200 days to get 20 level's maps with SAS.planet
program for some area)
5. So, I got new maps about 4TB from https://www.ngii.go.kr/ is
Korea's National Geographic Information Institute
6. But, I failed to load the new map in sample c# project
// Source code used in video C# project
providers.Add(providerid, "map", "http://127.0.0.1/map/z{zoom}/
<http://127.0.0.1/map/z{zoom}/>*{y}/{x}*.png",
tkTileProjection.SphericalMercator, 0, 13);
// Modified Source code
providers.Add(providerid, "map", "http://127.0.0.1/map1/z{zoom}/
<http://127.0.0.1/map1/z{zoom}/>*{x}/{y}*.png",
tkTileProjection.SphericalMercator, 0, 13);
7. After I found some differences.
- Sample's map is Google map based EPSG:4326 and file's array is
{zoom}{y}{x} and image's size 256*256 pixels
- But my new maps are based EPSG:5179 and files array is
{zoom}[x]{y} and image's size
512*512 pixels
If someone knows the way to load my new maps with ms4w
Please, let me know.
Thank you!
Best regards
Choi.
