MapViewer 10.1.2 SVG

Am I right in thinking that background images and therefore image themes, can't be used in an SVG request? If not, how is it done?

Yes, In version 9.0.4, I used to add a JDBC theme which was a polygon buffer around a line element. This was coloured (filled) in yellow with an opacity of 114. This was basically a method to highlight a region which had been selected. In the SVG this appears as a solid and bright yellow (which I guess has no opacity). If you like I can send you some images

Map Builder SVG onmouseover and onclick

Hi,
I'd like to know more about these functions in Map Builder.
I'd like to be able to change the color of a marker using onmouseover,
and select that marker by using onclick. Any info. would help.
Thanks,
Marlene

Hi Marlene,
these theme attributes (onmouseover and onclick) are to be used when you have an application with MapViewer that generates a SVG map. They define the method to call on your application script. MapBuilder does not generate SVG maps. You can fill these parameters with some name, and save the predefined theme. Then you need to develop an application code for SVG implementing these methods. After you deploy MapViewer kit, you should find on the MapViewer web page some demos including SVG.

Will MapBuilder ever export styles to SLD?

Hi there,
I was reading James' Fee blog at
http://www.spatiallyadjusted.com/2009/04/21/sharing-cartography/
and looking at various technologies for storing cartographic symbology and the thought occurred to me that it would be nifty if MapBuilder exported styles as OGC SLD. Currently it just seems to dump out the records as a pipe-delimited table.
Does anyone know if SLD is on the table? I know that mapviewer styles are basically SVG style snippets, so its already an open specification. It probably would not be an enormous task to wrestle these into SLD.
Just wondering what other folks have heard or are thinking.
Thanks,
Paul

Hi Paul,
thanks for your notes. SLD is not supported yet, but it may be supported in future versions.

Mapviewer demo mapinit.jsp with svg doesn't work with jdeveloper

hi ng,
i tried the source code for the svg-sample in jdeveloper and first of all jdeveloper dislikes the line "<embed id="map" src="<%= mv.getGeneratedMapImageURL() %>...". after "embed" a green line is to be seen.
When i start the sample the map looks okay, but when i want to hide a theme (or zoom), i get the internet_explorer-message "error on the page".
"themeVisibleArray[idx]='false';" goes right but the next line occurs the error: "map.window.hideTheme(theme) ;"
map is not known at this place, it seems to me.
who can help (please)?

Mapviewer SVG and Theme Selection

Im trying to highlight a line by clicking on the line. Im using the svg feature. Here is the xml request im using:
<?xml version="1.0" standalone="yes"?>
<map_request
title="Oracle LBS MAP"
basemap="demo_map"
datasource = "mvdemo"
width="640"
height="480"
bgcolor="#a6cae0"
antialiase="false"
format="SVG_STREAM">
<themes>
<theme name="theme1" selectable_in_svg="true" >
<jdbc_query
spatial_column="geom" jdbc_srid="8265"
render_style="transparent_color"
label_column="destination" label_style="t.street name"
datasource="mvdemo" key_column="origin">SELECT geom, origin, destination FROM flight_geometry WHERE origin ='PHX' and destination ='SDF'
</jdbc_query>
</theme>
</themes>
</map request>
The map is generated a line is displayed however, when I click on the line nothing happens. I set the key column and the selectable in svg attribute. Now when I look at the map, save the svg source to a different file and manually manipulate the featureselect variable in the svg javascript code, view the svg map and click on it it turns red. What is the correlation between the featureselect variable and mapviewer??? Am I not setting a parameter somewhere?? Any help would be appreciated.
Thanks,
Mo

I do not think the feature selection function is available on line features; it is only supported for Area and Point features. we will support linear feature selection/tool-tip functions in the next release.
A possible workaround is to identify a mid-point on the line feature, and place a marker on that mid-point feature. you can then select that point feature and display any information that might be associated with the underlying line.

Mapviewer SVG and Content-Type http header

Hello,
We have a Mapviewer installation that seems to be serving up the wrong Content-Type header for the SVG charts. The map is being created correctly and we can get GIF's and such.
The wrong Content-Type causes the Adobe SVG viewer to never render the SVG map successfully. When I save the SVG file to the desktop it opens perfectly or if I statically link it in to the web page from the sever it also opens perfectly. Is there some configuration that is missing somewhere on the mapviewer or the application server to correctly set the Content-Type ?
Notice the content type of the failing map compared to a working SVG chart we have.
HTTP/1.x 200 OK
Content-Length: 41979
Cache-Control: private

This seems to be the last sticking point in successfully rolling out this mapviewer implementation. Any help would be greatly appreciated.
Thanks, in advance.
Thanks,
Carl

Hello,
Thanks for the reply I've tried both SVG_URL and SVGZ_URL and used a http header sniffer to watch what's getting served up and the urls associated with MapViewer SVG are definitely getting served up with that wrong Content-Type.
Our front end is an Oracle APEX environment were we use APEX's SVG charting on the same page and they are getting served up with the correct Content-Type and display correctly, which is nice cause I can watch the header difference's side by side, and we know the mapping itself is working right because we can get image files back
Is there a sever config file or something like the httpd.conf for apache that needs to be set?
Thanks for any help or insight

JDeveloper - MapViewer - Svg

Hi,

Mapviewer svg jsp - example for enableFeatureSelect ?

hi,
can anybody give me a simple example for enableFeatureSelect/getSelectedIdList (or even for enablePolygonSelect to get some highway-id's)? in the demo mapinit.jsp with svg you can zoomin and recenter.
i want to create a new radio button for clicking on the svg and not to zoomin or recenter, but for selecting and highlighting a county.
how can i select a county so it changes its color and i can get the id for this county?
greetings
thomas

There is a SVG Territory Manager Demo that comes with MapViewer that can be downloaded from OTN. It alows you to select a county on the map and it uses the enableFeatureSelect and getSelectedIdList functioins. If you have not downloaded the latest 10.1.2 mapviewer and the demo data, you can download it from here, http://www.oracle.com/technology/software/products/mapviewer/index.html.
Basically you need to do the following things to make it work.
1. In the XML base map definition, set "selectable_in_svg" attribute and onclick function for the theme on which you want feature selection to be enabled . Here is an example,
<?xml version="1.0" standalone="yes"?>
<map_definition>
<theme name="STATES" min_scale="50.0" max_scale="4.0"/>
<theme name="COUNTIES" min_scale="4.0" max_scale="0.0" min_dist="0.5" selectable_in_svg="true" onclick="selectCounty"/>
<theme name="STATES_LINE" min_scale="4.0" max_scale="0.0"/>
<theme name="HIGHWAYS" min_dist="1.0"/>
<theme name="CITIES" min_scale="1.2" max_scale="0.0" />
</map_definition>
2. Define the onclick javascript function in your jsp/html page where the svg map is embedded. For example, if you have created a base map using the sample XML shown above, you should define a javacript function called "selectCounty" to handle the mouse click event when the feature is clicked. Inside this javascript function, you can call getSelectedIdList to get the id of the clicked feature.
3. In your jsp/html page, call javascript function enableFeatureSelect to enable single feature selection.

Get coordinates from mapviewer svg output (JavaScript)

hello,
i would like to read the coordinates of the mousepointer moving over the svg output of the MapViewer using java script in datas coordinate systems (not screen!).
the svg is included by the object-tag of html (like an image).
has somebody done something like this, i´m new to JavaScript an don´t want to reinvent the wheel.
Maybe there is an easy way to solve this, but i don´t know.
thanks

Hi,
We strongly recommend that you look into using Oracle Maps when developing mapviewer applications. It has an open and well documented JavaScript API, unlike the SVG support which is currently on the back burner.
If you have to use SVG, there is a chapter in the MapViewer User's Guide that documents some of the javaScript functions you can use.
thanks

Adobe svg viewer required for MapViewer 10.1.2 preview ?

Good morning.
When using the mapinit.jsp demo with the preview of MapViewer 10.1.2 I found that the svg file would not display. I clicked on the Adobe SVG viewer icon in the lower left corner of the jsp, downloaded and installed the viewer, then found that the svg file displays properly. I couldn't find the Adobe SVG viewer in the list of software prerequisites for MapViewer. Did I miss something in MapViewer 10.1.2 setup ? Is Adobe SVG viewer required ? Are there other options ?
Thanks.
alan

Yes Adobe SVG viewer is required to view the svg maps.
Currently there is no other option.

MapViewer 10.1.2: Interactive SVG in a JSP page

Hello everyone,
I'd like to be able to embed an interactive SVG map in my JSP page (similar to the mapinit/svgmap demo).
What is the simplest way to do it? Is there a JSP tag that would render a map with all javascript?
I'd like to avoid having lots of Java and Javascript code in my JSP definition.
Thanks,
Max

There is no such JSP up to this point. Currently, you have to have some java and Javascript code to implement the control flow. If you want your JSP code to look cleaner, you can move the Javascript code into a seperate JS file and use <SCRIPT TYPE="text/javascript" SRC="myscript.js"></SCRIPT> in your JSP code.

Mapviewer demo mapinit.jsp with svg

hi,
the demo shows me per tooltip the number of a highway or the data about a county.
how can i in a jsp-file get the highlighted data out of the svg-map, for example:
if i get a tooltip for a highway and i click the mouse, i want to (onclick) get the highwaynumber. all i know now is that i can get the rowid of the selected feature.
function my_feature(theme, id, x, y)
alert('my_feature 1');
alert(theme);
alert(id);
s_str = map.window.getinfo(theme, id); --> error
alert('my_feature 2');
is getinfo the right method?
thomas

getInfo is the right method for your purpose. However, getInfo returns the whole info tip string and you need to extract the attribute that you need from it.

Unable to get the SVG demos to work in mapinit.jsp

Hi forum
I've played a bit around with the Mapviewer demos for Oracle Maps. I have loaded the demo data in a database and done the setup as described in the setup. Everything works - except all demos related to SVG, like mapinit.jsp in this case. I've tried both version 10.1.3.1 and 10.1.3.3. I've tried this in misc. browsers, and here's what happens in each
IE7 + Adobe SVG Viewer: The SVG window is blank
Firefox 3: For Mapviewer 10.1.3.1, displays a "Malformed XML document error". For Mapviewer 10.1.3.3, wants to install an "Unknown plugin" which it then can't find, and doesn't display anything.
Google Chrome: Outputs an XML document as text in the SVG window
I have tried adding an entry to mime-types like "image/svg+xml svgz", but that didn't seem to change anything. No browser wants to display the SVG correctly.
Choosing "Regular image" for the same demo data works fine.
How do you get this to work? What am I missing? The appserver runs 10.1.3.4.
Thanks in advance,
Jacob

Hi Jacob,
Since Adobe dropped support of their SVG viewer, MapViewer SVG support has not been updated with the new features added. Therefore, do not expect to get in SVG, what you currently get with other formats. The minimum support initially added for SVG, is still there. We will check the demos.
Different browsers provider different levels (some rather incomplete) of support for SVG, and scripting with SVG is also done differently on different browser/platform, so this makes difficult to keep SVG support updated. You experienced these differences in your tests with different browsers.

Mapviewer: circles in legend

for some reason Mapviewer renders circle-markers as ellipse. The style is dynamic:
mv.addMarkerStyle("SL.OK", MarkerStyleModel.MARKER_CIRCLE, "black", "green", null, null, null, "5");

I browser mapviewer/demo/mapinit.jsp and select SVG.
Everything works fine except there is no map displayed in the window.
If I choose regular image, everything is fine.
Does anyone have ideas about it?

Hi,
Do you have any errors (client or server), any log-Messages?
This is the first thing i would look for.
