Hi Stefan,
I don't know if I understood you correctly, but I think the solution for
you would be an image catalog, right?
Then you would have only one layer for the UTM maps.
In the mapfile it would look like this, in the .dbf in the column
"location" would be the paths to the png data.
LAYER
NAME "utm_data"
STATUS ON
MAXSCALE 8000
TILEINDEX "filesindex_png.shp"
TILEITEM "location"
TYPE RASTER
PROCESSING "Resample=average"
CLASS
name "utm_data"
END
END
Greetings Sven

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
