[MapServer-users] "Emergency" map server on Raspberry Pi - raster/PNG source in folder structure

[Stefan Gofferje]

Hi all,

Life (and COVID) hit, so I never got anywhere with updating my weather 
website and taking mapserver into use there.

Currently I have another project - due to the geopolitical situation:
I'm working on a mobile system to provide emergency/off-grid "tactical" 
communication and data. It's centered on a Raspberry Pi and includes 
things like Meshtastic and others. One of the things I would like to add 
is a WMS/WFS server to provide map data via local Wifi AP to connected 
devices.

Topographical (and other) maps of whole Finland are available under CC4 
from the Finnish Land Survey through the KAPSI non-profit. The maps are 
in 12kx12k PNGs in a folder structure by UTM grid. See here: 
http://kartat.kapsi.fi/files/peruskarttarasteri_jhs180/taustavari_korkeuskayrilla/1m/etrs89/png/
The data can by rsync'd down.
I'm not clear how I would configure mapserver for that. Do I have to 
create one map with extent and such for each PNG tile or can I point 
mapserver to the root directory  of the data and tell it to go through 
it recursively and get the data from the PGW sidecar files?

-Stefan
