However that is still brush line for the railway symbol which is not supported

to see if that works at your side?

RailRoad Symbol I am using is as follow:

It works as expect when the return image in raster format such as PNG, but when

Does anyone have any suggestion about how to design a vector-enabled symbol for 
railways please? I am using MapServer 7.0, data is in SQL Server Spatial.

Without seeing the "tie" symbol, its hard to say if mine is different.
Here's how I draw mine:

Re: [mapserver-users] PostGIS date queries performance issues

2016-11-18 Thread Lime, Steve D (MNIT) 
Tom: There were definitely changes in this area. Can you share the WFS filter 
plus the resulting SQL in each version. This is the type of thing that should 
have gotten better in 7.0 as WFS filters are translated more completely into 
native SQL. It’s possible I introduced an inefficiency in that translation 
beyond what was done for PostGIS in mapogcfilter.c in 6.4.  -Steve

Subject: [mapserver-users] PostGIS date queries performance issues

Hi all: using 7.0.2 against a PostgreSQL 9.3/PostGIS 2.2 instance we're getting 
very long (timeouts even) response times when doing WFS filters against 
PostgreSQL date types.

I've posted a Gist at [1] to help in reporting.  Note that this functionality 
used to work with acceptable performance in 6.4.x.

Looking deeper (see Gist) it appears that the SQL queries that MapServer crafts 
for PostgreSQL are different.  When I try the 7.0.2 based SQL in a psql prompt, 
the same very long response time results.

Any idea what could be going on here?

Thanks

..Tom

Thanks for the reply!  You are correct:  the images I displayed are zoomed
pretty far in, resulting in heavy oversampling.  Here's a sample showing
one pixel (blue highlight) on the heavily oversampled image:
http://i.imgur.com/scO8iIm.png  It is the oversampling I am trying to
understand.

Here is a heavily oversampled GetMap with data which went through gdalwarp
to reproject the data from 4326 to 3857... then I use Mapserver to display
the results setting the input & output PROJECTION blocks to 3857:
http://i.imgur.com/MrfDb1E.png I expected Mapserver reproject on the fly to
look more like this.  Instead, oversampled pixels are stretched, like this:
http://i.imgur.com/bw4pNPX.png

I played around with various `PROCESSING "RESAMPLE=resample_method"` in my
layer, but I get the same stretched output on heavily oversampled output
using Mapserver to reproject on the fly from 4326 to 3857.  When zoomed out
to near-native resolution of my monitor, the output looks great. I only
notice the stretching when oversampled. What is Mapserver using to
reproject on the fly?

Thanks again!

[mapserver-users] Mapcache support for multiple format types

2016-11-18 Thread tellett 
Hi all,

I'm wondering if theres any other way in mapcache to support multiple
formats (png and jpeg for example) than to create a new tileset?

For example if I have a wms 'source' called topo2_wms (that supports png and
jpeg), and a tileset called topo2cache, whats the best ways to create tiles
in both png and jpeg? Is it really necessary to create 2 tilesets, 1 called
topo2cache_png and one topo2cache_jpeg?

Re: [mapserver-users] PostGIS date queries performance issues

2016-11-18 Thread Eichner, Andreas - SID 
Besides comparing the execution plans for both query versions, you could try:
1. omit the outer ORDER BY clause (not present in MS6 and the inner one is not 
relevant for the result, so might be optimized away by the planner)
2. try the MS7 SQL without the superfluous st_intersects() part (it might not 
use the spatial index in the same way as the "&&" operator)
3. replace the time comparision part with the MS6 BETWEEN construct
4. try all at once and/or combinations of them

At least one should help you identify the cause. If you've found it post it 
here so that one could search the generating code.
