Re: [mapserver-users] wms servers html template output

Travis,

We went with a slightly more involved route of caching things locally in a 
Postgres database.  You can automate things to a certain extent with a REST 
service for example with some clevering automation scripting for example.  We 
had to figure out things like how to handle when attributes changed, etc, but 
it was doable from a REST service.

Hi Travis: I don’t think there is an “easy” way. I mean you could script 
template creation so that process does the tedious work for you by looking at 
the map. You would create a new-style template (see RFC 36) so everything is in 
one file and then you’d create a single output format reference to that table.

If we wanted to support this via MapServer templates I think we’d need to do 3 
things:

• Extend the [resultset] tag to support “layer_pattern” attribute so 
that it (a regex) could apply to multiple layers (like any/all of them).
• Enhance the [items] and [values] tags to control formatting. 
Currently those just slam the column names and values together in a delimited 
string.
• Enhance the [values] tag processing to allow referencing the 
associated item/column name in the context of formatting.

I’d probably also propose compliance with the item-related metadata that is 
typically used with OGC service outputs to control which items are output…

With those changes you could write a template like so:

// MapServer Template
[resultset layer_pattern="."]
[feature]

[values format=”$item$value]

[/feature]
[resultset]

This would give you an item/value table for any feature for any layer. You 
could also to more horizontal tables using the [items] tag to output one header 
row…

Hi all,

I'm struggling a bit with using a generic template for html getfeatureinfo 
requests.  Is there a easy way to create a simple html table containing the 
attribute field names and values for any layer.  I don't want to create a 
separate template for each layer.  Thanks

There was some mention of this here:

Re: [mapserver-users] Doubling of labels on high resolution maps

2019-10-16 Thread Rahkonen Jukka (MML)

Hi,

Print composer is probably making tiled requests from WMS. That is compulsory 
for any bigger maps because the default maxsize on the Mapserver side is 
2048x2048 pixels https://mapserver.org/uk/mapfile/map.html. It is easy to 
increase the maxsize but I do not know if print composer as a client can be 
aware of that.

Partials FALSE may help, but based on the screenshot it is possible that print 
composer is making requests with some overlap.

There are a few options you could add to your label but I would start with

MINDISTANCE 200
