[Geoserver-users] Label Callouts
Hello everyone, Can someone tell me if Geoserver supports automatic callout style labelling or whether there are plans to support it in the near future? I'm talking about, at a simplistic level, using a line to link the label to the feature in the event that the label is moved a significant distance from the feature as a result of label placement/decluttering etc. Thanks Chris *** This communication has been sent from World Fuel Services Corporation or its subsidiaries or its affiliates for the intended recipient only and may contain proprietary, confidential or privileged information.

[Geoserver-users] graphic-margin
Ok, I don't think this is a CSS Module issue at all. Straight forward SLD such as: sld:VendorOption name=graphic-resizestretch/sld:VendorOption sld:VendorOption name=groupfalse/sld:VendorOption sld:VendorOption name=graphic-margin8 12/sld:VendorOption Seems to result in the same error on my system. Although there is a jira ticket from 2010 which implies that this work has been done and tested http://jira.codehaus.org/browse/GEOT-3238 Currently using version 2.2.5. Is anyone else able to verify the same problem?

[Geoserver-users] Where to start?
Hello list, I really haven't a clue where to start with this so any pointers would be gratefully received. I have a global data set residing in a postgres/postgis database. The geographic spread of the data is random, some areas have a lot of points whereas others have quite sparse points. The data basically boils down to a location and an integer value between 0 and 4. I would like to represent this data as a series of fixed sized cells (shape not important but hexagonal would look nice!). If no data point resides within a cell I'd like to colour the cell purple. If more than one data point resides within a cell I'd like to colour it based on only the highest number amongst those points within the cell. I'd like the cells to completely cover (and probably be clipped by) by coastline data. The net effect I'm after would be the landmasses shown as a patchwork of coloured cells. I have tried playing around with a gs:BarnesSurface but I don't see able to get the results I'm after with this method. Any ideas?

Hi Martin, I simply made sure that the SVG symbol was defined on a square grid (100x100) and that the point I wanted as the reference point was located in the middle i.e. 50,50.

Hi Jonathan, It isn't a fixed value. The offset seems related to the zoom. As I zoom in the symbols moves closer and closer to where it should be and as I zoom out it moves further away!

Subject: Re: [Geoserver-users] CSS and ColorMaps
No, you can't do this right now. I've actually been working on it a bit
recently (raster styling doesn't work all that naturally in CSS, but it seems
like a prerequisite for styling transformations):
https://github.com/dwins/geoscript.scala/commits/raster-styling
If you're interested in trying it out I'd love some feedback, but I don't think
I can support builds of this experimental branch, so you'd have to build it
yourself from sources (feel free to bug me off-list for details.) I don't have
things documented yet but at least the property names for raster styles are all
together in the sources:
https://github.com/dwins/geoscript.scala/blob/9ff23dccfed0201f3c05cde80456386336323f70/geocss/src/main/scala/org/geoscript/geocss/Translator.scala#L622-L644
A basic raster style would look like:
* {
raster-channels: auto;
raster-color-map:
color-map-entry(black, 0)
color-map-entry(red, 100)
color-map-entry(green, 200);
}

Thank you David. I will try this this morning. Another related question though. When I define an SVG symbol for use like this how big should the original symbol be or does it not matter and it is 'tuned' via the symbol size values in the SLD/CSS?

SVG icons would be good - when you have GeoServer manipulating your icons, storing them in a vector format helps to reduce visual artifacts. If SVG's not an option for whatever reason, using high-resolution icons can also help avoid problems.

[Geoserver-users] Label shields as direction indicators
Hello List, I would like to be able to render road numbers inside a shield where the shield itself is used to indicate direction. I'm guessing that I would require 3 different shield symbols (SVG?), or possibly just two if one can be rotated. One symbol would be a rectangle with an arrow at each end (indicating bidirectional) the other(s) a rectangle with just the arrow at one end (indicating direction) So, I have a couple of questions: * Is this the correct approach for achieving this objective? * How do you control the orientation of a label shield in order to have the arrow pointing in the correct direction? The data has an attribute of Forward, Backward or Both relative to the order in which the line is defined. Any helps or pointers greatly appreciated.

[Geoserver-users] Polygons with outlines using gradients
Hello all, Is it possible to style polygons so that their outline appears as a gradient? I'd like to define a coastline, for example, using a line that is, say 5 pixels wide, but whose colour fades to transparent. The gradient should be oriented with the solid colour closest to the inside of the polygon and the lighter colour furthest away from the polygon. Not the best explanation, but hopefully you will understand what I mean!

Re: [Geoserver-users] gs:Heatmap problems
Thanks for the input Martin. I can understand that 41K points may be an issue but even when I request a much smaller bounding box in order to significantly reduce the number of points being used I still don't get anything displayed. The data is a regular grid of points with a 1.25 x 1.25 degree spacing. The CRS is EPSG:4326. Would you be able to suggest suitable values for the other parameters, namely: Scale, convergence, minObservations, maxObservationDistance (not sure if this should be meters or degrees), pixelsPerCell and queryBuffer?

[Geoserver-users] Decluttering/SLD/CSS
Hello list and HNY to you all! This is probably a very basic question so if someone can point me in the right direction it would be greatly appreciated. I understand how to control labelling based on zoom level, priority and z-order to manage the clarity of the map. I also understand how to display or not display point symbols based on zoom level filters. BUT I can't work out how to control drawing symbols with the same degree of control as I have over labels. I have points on a map that are more important than others but are all in the same layer. In areas where there are a lot of points, and the scale doesn't support drawing them all clearly, I want to only display just the important ones (and their labels) but as the user zooms in and the screen real-estate increases I want to display more i.e. include the less important points. This is all doable via the scale filters, but causes an undesirable issue in areas where there are a low numbers of points - they only become visible when you are zoomed in. In these areas I would like to be able to display the less important points at the same time as limiting the display of points in the more congested areas to only show the important ones. Any ideas on how to achieve this?

A next approach is actually to abuse the TextSymbolizer: 1. Use a type face that contains the symbols you would like to plot, e.g, OpenSymbol, Symbol 2.

This is probably a very basic question so if someone can point me in the right direction it would be greatly appreciated. I understand how to control labelling based on zoom level, priority and z-order to manage the clarity of the map. I also understand how to display or not display point symbols based on zoom level filters. BUT I can't work out how to control drawing symbols with the same degree of control as I have over labels. I have points on a map that are more important than others but are all in the same layer. In areas where there are a lot of points, and the scale doesn't support drawing them all clearly, I want to only display just the important ones (and their labels) but as the user zooms in and the screen real-estate increases I want to display more i.e. include the less important points. This is all doable via the scale filters, but causes an undesirable issue in areas where there are a low numbers of points - they only become visible when you are zoomed
[Geoserver-users] CSS Question
Hello list!
I am using an SQL view which returns multiple geometries in each row.
Each row represents a trip and contains Departure and Destination points and a
linestring representing the route taken.
I'm not sure how to use CSS to define different symbols based on the SQL
columns. E.g. use a triangle for the Departure and a square for the Destination
I would like to do something like this:
[Departure]{
mark:symbol(triangle);
}
[Destination]{
Mark:symbol(square);
}
But that doesn't appear to be the way to go ;)
Any help appreciated!

[Geoserver-users] Projections
Hi Guys, This is a two stage question. Warning: some parts may be dumb! ;-) I'm using geoserver in conjunction with postgres and postgis. Is it possible to request maps using projections that are defined dynamically? And if yes, how would you define a projection defined along the following lines.. The same as Polar Stereographic but centred on a longitude/latitude anywhere on the Earth's surface. Ideally with a way to specify the geographic extents of the 'map'. I'm not sure how these extents would be defined but probably either by specifying a radius in nautical miles from the centre point or perhaps in terms of number of degrees of longitude/latitude from the centre point or something else entirely? Ideally, what I would like is to be able to define a point on the Earth along with some way of indicating how much of the earth's service is required and convert this into whatever projection information is necessary to allow geoserver to render it correctly. Any ideas/help greatly appreciated.

Re: [Geoserver-users] Label / Character Question
Thanks David,
I had already used this approach but it didn't seem to allow me to achieve an
effect I was after...
I have used this approach to show a symbol and on another layer I need to show
a text value next to it.. but the automatic moving of the label as part of the
conflict resolution didn't appear to be behaving as I expected and I assumed it
was because the 'symbol' wasn't being treated as a label.. hence why I was then
trying to do the same thing using labels.

[Geoserver-users] SLD Rotation
Hi All, I have a question.. If I want to use the ESRI Weather font to display symbols that indicate wind speed and direction then that would appear to be quite straight forward in a Cartesian projection as rotating the symbol to the value given for the wind direction will give the correct result. But I suspect, and this is my question, that when the background map is projected into, for example, a polar stereographic projection rotating the symbols via the SLD will give incorrect results. Could someone confirm this suspicion and maybe point me in the direction of how to ensure that the TTF symbol rotation is always correct regardless of the projection?

Re: [Geoserver-users] Rookie Question
Thank you David,
It was the missing bracket - doh!
In reality im not really wanting to just join two strings, I was using that as
a simple example to see if the CQL syntax was correct. I really need to be able
to calculate the EC part of that example. Which is a simple calculation but I'm
not sure how to represent the result (easily) in hexadecimal notation.
I believe that the font expects the required character to be specified as
0x00?? Where the ?? is the number that I'm calculating (in decimal)
Does CQL have a function to convert decimal to hex?

If this is exactly what you have in your style then it is simply an invalid CQL
expression: you need to close the parentheses before you close your ${} block:
mark: symbol('ttf://ESRI Weather${strConcat(#0x00,EC)}');
By the way, strConcat is rarely, if ever, necessary in dynamic symbolizers.
Instead of ${strConcat(prefix, suffix)} you can use the more concise
${prefix}${suffix}. So I would write your example as:
mark: symbol('ttf://ESRI Weather${#0x00}${EC}');
There's one less level of nesting this way, and I think it's easier to count
the braces.

Well, there are actually two kinds of functions in GeoServer CSS: css functions
like url() and symbol(), and CQL functions like [strConcat]. Implementation
wise, there is no effort to combine the two (and the error message you get
indicates I didn't even do a very good job of reading expressions that mix them
:P).
You MAY be able to get it working by using the same syntax you would in SLD:
mark: url(wind/wind${strConcat(fixedspeed, northernhemisphere)}.svg);
If it doesn't work, please let me know (or if you have a Github account you can
file a bug on the GeoScript scala project yourself):

Rotation
ogc:Function name=if_then_else
ogc:Function name=equalTo
ogc:PropertyNamefixedspeed/ogc:PropertyName
ogc:Literal0/ogc:Literal
/ogc:Function
ogc:Literal0/ogc:Literal
ogc:Function name=toDegrees
ogc:PropertyNameangle/ogc:PropertyName

Re: [Geoserver-users] Z-Order Question
Each layer contains different features and each is styled so that a particular featured is rendered differently based on a scale within that layer. For example there may be a feature on one layer that represents an object. At one scale it will be rendered as a mark e.g. triangle, but then it may be rendered as an external image at a closer zoom. The issue is that certain layers have features that are more important than others and all are drawn at the same time. From: Jay L.

[Geoserver-users] More CSS Questions
Hello list!
I have two questions in relation to the CSS module.
Firstly, using units of measurement. Could someone supply an example of the
syntax for this? I have tried:
mark: symbol('circle');
mark-size: 1m;
also
mark-size:1 m;
But neither seem to work. The first results in nothing getting drawn and the
second results in the mark being drawn at 1 pixels!
Secondly, if I want to use an external symbol (e.g. a PNG or SVG file) and have
this scaled using UoM what size/scale does the image have to be created at in
order for it to scale correctly?
Thanks
Chris

The CSS module never collapses whitespace inside of quotes, even across
linebreaks. Additionally, in the special case of labels any number of property
values will be implicitly wrapped up in calls to the concat function, similar
to the handling of multiple values in SLD.

Re: [Geoserver-users] css Question
I may have spoken to soon!
Yes, that does give me multiple lines for the label, but it appears to cause an
issue with the positioning of that text within a shield.
I'm using a square symbol in 'stretch' mode for the shield. The shield looks to
be the correct size and shape hold the multi-line label but the label is not
positioned correctly within the shield, it starts in the center of the shield
and then overflows the bottom of the shield.
Is this a known issue? Is there away to control (fine tune) the positioning of
the text within the shield?

Re: [Geoserver-users] Geoserver CSS Module
Thank you David, that was a huge help!
Ok, the part of the documentation I found confusing was in how to actually make
reference to the Hospital mark that the example defined. I could understand
the construction of the symbol but wasn't then sure how to assign it to points.
It would also have helped if there was an explanation of what usage was doing.
I have one more question in this area which I can't find any documentation for..
I would like to define a rule which uses an external SVG file as a symbol for a
point. How is this done in CSS? I have tried the following without success:
mark: url(MySymbol.svg);
Where MySymbol.svg is located in the data_dir/styles directory.
Thanks

Subject: Re: Geoserver CSS Module
Hi Chris,
I hope it's not a big deal to bring this to the users list; in general I prefer
to answer CSS questions there so Google can help the next person to have your
problem ;)
Yes, the docs are a bit confusing. (It's a common trap for developers - in SLD,
styled marks rely heavily on nested XML structure, so finding a decent way to
encode this in CSS was kind of tricky. Then when I wrote up the documentation
I only gave an example of the most complicated case - using multiple different
symbols with different styling. If you have suggestions on clarifying the
documentation here I would be happy to incorporate some edits.)
Anyway, for basic styled marks, it's fairly straightforward: you can think of
the mark as a new, polygon geometry and use stroke and fill parameters for
that. A rule with :mark in its selector will match these synthetic
geometries (:stroke, :fill, and :shield work for geometries generated for
stroke patterns, fill patterns, and label shields respectively, and you can
also use :symbol to match any generated symbol.)
You need at least two rules: one to generate this synthetic geometry, and one
to style it (but as a convenience, if you don't style it it will have a
grey/black theme.)
* {
mark: symbol('circle');
}
* :mark {
fill: red;
stroke: black;
}
Or, specifically for the example you gave:
[@scale3400][@scale6900][longest_runway_ft8000]{
mark: symbol('circle');
mark-size: 2;
halo-radius: 3;
halo-color: #FF;
label: [icao_identifier];
label-offset: 0.0 0.0;
label-anchor: 0 0.5;
-gt-label-padding: 20;
-gt-label-priority: [longest_runway_ft];
}
[@scale3400][@scale6900][longest_runway_ft8000]
:mark {
fill: #FF;
}

Hi David,
I hope you will forgive the direct email.
I have been evaluating your CSS styling module for Geoserver. I am relatively
new to Geoserver fullstop, but must say that I think the CSS option is a
massive improvement over having to work with SLD, so a big thank you for the
work being done in this area.
My question is probably quite a simple one but for the life of me I cannot find
the answer anywhere!
I wish to use marks on my map (circles) and I wish them to be coloured based on
an attribute of the data. I don't seem to be able to get any colour info to a
symbol using CSS. I looked at the example of a hospital symbol, which would
imply that it can be done, but I couldn't try this as I didn't know how to
reference the 'hospital' as a mark (I tried - mark: symbol('hospital') but that
didn't work).
As an example here is a CSS rule that I am defining:
[@scale3400][@scale6900][longest_runway_ft8000]{
mark: symbol('circle');
mark-size: 2;
fill: #FF;
halo-radius: 3;
halo-color: #FF;
label: [icao_identifier];
label-offset: 0.0 0.0;
label-anchor: 0 0.5;
-gt-label-padding: 20;
-gt-label-priority: [longest_runway_ft];
}
The fill:#FF; line is where I am expecting it to render red circles, but I
just get grey ones!
I think this problem is a result of what I am doing and not necessarily a bug
etc. so I would appreciate if you could tell me where I'm going wrong?
Many thanks
Chris
