Is there any way to avoid old mapserver-user list to work independently?
as it was impossible to unsubscribe to that list and people didn't get
that serious the list change, now there are two split mapserver's lists.
am I wrong?
regards
Lorenzo

Subject: Re: Perform spatial filter in 2 different layers (e.g. "Which cities does Road X cross?")
Dimitrios,
Check out http://mapserver.gis.umn.edu/docs/howto/filterencoding. A WFS
Intersect filter would look like:
http://example.org/url?&version=3D1.0.0&service=3DWFS&request=3DGetFeatur=
e&typ
ename=3Dpopplace&filter=3D<Filter>
<Intersect><PropertyName>Geometry</PropertyName><gml:Polygon><gml:outerB
oundaryIs><gml:LinearRing>
<gml:coordinates>2488789,289552 2588789,289552 2588789,389552
2488789,389552 2488789,289552</gml:coordinates>
</gml:LinearRing></gml:outerBoundaryIs></gml:Polygon></Intersect></Filte
r>
=20
Of course, how you acquire (WFS request) and setup / pass those
geometries is up to your middleware. I'm not exactly sure whether
MapServer's support of the Intersect filter works only with gml:Polygon,
or other types. Assefa would know best here.

Subject: Help: generating "meta - symbols" dynamically
This is a multi-part message in MIME format.
------_=_NextPart_001_01C8731D.7BB0CA62
Content-Type: text/plain;
charset="us-ascii"
Content-Transfer-Encoding: quoted-printable
I have a need to summarize my spatial data with what I will call a
"meta-symbol", i.e., a symbol that represents more than one data column,
with more than one state for each column. I could create a symbol file
containing all of the combinations of such a symbol, however, this can
become a very large group of symbols in very short order.=20
=20
For example, I have a map which shows geographical regions, and I wish
to summarize the drought status of each of those entities for 4
different metric: 1) rainfall, 2) stream flow, 3) groundwater levels,
and 4) reservoir storage values. I have 4 categories of drought
indicator: 1) no drought, 2) drought watch, 3) drought warning, and 4)
drought emergency. I believe that this makes my number of possible
combinations, 4^4, or 256 different categories. If I were to add a 5th
indicator, then I would end up with 5^4 possible combinations, or 625
different combinations.
=20
One possible approach that I have thought of is to create a rectangular
grid (with cells for each indicator) for each geographic area, located
at its centroid, then place a symbol in each grid cell. This would
reduce the overhead to 4 symbols, that would then be dynamically
assigned by mapserver to the drought value. I am concerned about
registering these properly within the cell.=20
=20
Any feedback on my proposed approach, or examples of something similar
would be appreciated,
=20
Thanks in advance,
r.b.

Dimitrios,
Check out http://mapserver.gis.umn.edu/docs/howto/filterencoding. A WFS
Intersect filter would look like:
http://example.org/url?&version=3D1.0.0&service=3DWFS&request=3DGetFeatur=
e&typ
ename=3Dpopplace&filter=3D<Filter>
<Intersect><PropertyName>Geometry</PropertyName><gml:Polygon><gml:outerB
oundaryIs><gml:LinearRing>
<gml:coordinates>2488789,289552 2588789,289552 2588789,389552
2488789,389552 2488789,289552</gml:coordinates>
</gml:LinearRing></gml:outerBoundaryIs></gml:Polygon></Intersect></Filte
r>
Of course, how you acquire (WFS request) and setup / pass those
geometries is up to your middleware. I'm not exactly sure whether
MapServer's support of the Intersect filter works only with gml:Polygon,
or other types. Assefa would know best here.
Yiasou

Hello list.
I'm trying to perform somewhat more complex filters using the
WFS. More specifically, I want
to do the following, which I found in the list:
=20
[..]
Ah, ok. For that kind of scenario (and I want to find :"The
Road with name X which Cities crosses ?"), you could:
- query a roads WFS to get geometry
- pass these geometries to a WFS Intersect filter to seek
=20
..Tom
[..]
=20
Supposing I manage to get the geometries of the roads contained
in a bounding box.
My question is: how will I pass the geometries that the first
filter returns to an intersect filter
in the other geometry using the KVP (Keyword-Value Pair) way?
=20
Thanx a lot,
Mimis

Subject: Re: Help: generating "meta - symbols" dynamically
Thanks Bobb,
I will look into that. After posting, I got to thinking, and I am
experimenting with using a pie chart (of fixed percentage), trying to
work out a dynamic color for the pie slice. Your approach seems a bit
more robust to be sure, although I am not sure I totally understand how
to go about it.=20
With your approach, would this be a set of CLASS'es that turn themselves
on/off based on a condition?
FWIW it would be interesting to look at expanding the Chart type to
contain more types, that could be used to achieve this type of effect as
well.
Thanks again!

Robert,
What about using a stacked symbol type, something where you could see
any of the particular symbols, but they are all stacked on top of each
other depending upon whether they apply or not. Then you only need a
fairly small set of pre-defined symbols, but the combinations take care
of themselves based on the symbol stack that is displayed.

I have a need to summarize my spatial data with what I will call a
"meta-symbol", i.e., a symbol that represents more than one data column,
with more than one state for each column. I could create a symbol file
containing all of the combinations of such a symbol, however, this can
become a very large group of symbols in very short order.=3D20
=3D20
For example, I have a map which shows geographical regions, and I wish
to summarize the drought status of each of those entities for 4
different metric: 1) rainfall, 2) stream flow, 3) groundwater levels,
and 4) reservoir storage values. I have 4 categories of drought
indicator: 1) no drought, 2) drought watch, 3) drought warning, and 4)
drought emergency. I believe that this makes my number of possible
combinations, 4^4, or 256 different categories. If I were to add a 5th
indicator, then I would end up with 5^4 possible combinations, or 625
different combinations.
=3D20
One possible approach that I have thought of is to create a rectangular
grid (with cells for each indicator) for each geographic area, located
at its centroid, then place a symbol in each grid cell. This would
reduce the overhead to 4 symbols, that would then be dynamically
assigned by mapserver to the drought value. I am concerned about
registering these properly within the cell.=3D20
=3D20
Any feedback on my proposed approach, or examples of something similar
would be appreciated,
=3D20

Subject: user wfs?
Hi all.
We are compiling a map of Italian GFOSS users and realizations:
http://www.gfoss.it/drupal/cat_wg
and we would like to add UMN Mapserver users: is a WFS service available
somewhere?
If not, wouldn't it be a good case for OSGeo stepping in?
All the best.
