Map Legend

Hi All!
Is it possible to get the map legend in a separated image using the MapViewer API?
I have done it using the MapViewer tag library, with the <mv:makelegend> ...
Is it possible not use the tag library, but the API?
Thank you!
Carlos

Carlos,
It is indeed possible to send a map request, using the XML API, for a nonembedded legend (return a legend without a map). To do this, simply send a standard MapViewer request, without a basemap, using the legend tags:
<?xml version="1.0" standalone="yes"?>
<map_request
title="Oracle LBS MAP"
datasource = "mvdemo"
width="640"
height="480"
bgcolor="#a6cae0"
antialiase="false"
format="PNG_STREAM">
<legend bgstyle="fill:#ffffff;stroke:#ff0000" profile="MEDIUM" >
<column>
<entry text="Map Legend" is_title="true" />
<entry style="M.STAR" text="center point" />
<entry style="M.CITY HALL 3" text="cities" />
<entry style="M.CITY HALL 4" text="big cities" />
<entry is_separator="true" />
<entry style="C.ROSY BROWN STROKE" text="state boundary" />
<entry style="L.PH" text="interstate highway" />
<entry text="County population:" />
<entry style="V.COUNTY_POP_DENSITY" tab="1" />
</column>
</legend>
</map_request>
Hope this helps.

Gis map legend missing on .pdf exporting

Hi guys,
i've a big problem with the WAD exporting for printing.
I've a simple gis map template with legend visible.Template is running fine on internet explorer but when i try to print report (right clic on the map - printable version) in the output .pdf file the legend is missing.
I try everything: with ie print, with adobe pdf ie add-on, exporting in excel format but the map legend is always missing.
Can anyone help me?
Thanks in advance.
Andrea

Hello Andrea,
you should check the properties for the map web item in your export template.
The content template is 0ANALYSIS_PATTERN_EXPORT for the print version.
There might be the "display legend" flag turned off.

Map Legend changes when scrolling map vertically

With the map scrolled all the way out, when you move it vertically it, the legend changes
With map in middle. 5000km:5000miles
with map lying on bottom of screen 5000km:2000miles
with half of map scrolled out of the screen 200km:100miles
with map out of screen 10km:5 miles

Yes. Old Mercator will mess you up everytime.
On the maps that only cover a small area, the scale makes sense, but on the map of the whole world, the scale is non-linear and not the same in all directions, so you can't use it for much.

Is there a MSE/Prime Infrastructure map legend?

I am looking for a legend for the maps in Prime Infrastructure. I have found one, but it only has a few items on it. I have many showing up on my maps along with numbers on the side of them. Any document to reference would be great. Thanks!

Hello,
May the link below help you out:-

Mapviewer legend and note overlap

I am using Mapviewer 11ea and wish to place a legend above a note in the SOUTH EAST corner of my map. The note is defined in the config file and the legend is provided in the map request. The legend itself seems to create a box larger than required and overlaps the note text below. See the image at http://www.geocities.com/ozspatial/legend-note-overlap.jpg showing the overlap and the large amount of white space at the bottom of the legend.
The legend component of the request is from the default mapviewer request and looks like:
<legend bgstyle="fill:#ffffff;stroke:#ff0000" profile="MEDIUM" position="SOUTH_EAST">
          <column>
            <entry text="Map Legend" is_title="true" />
            <entry style="M.STAR" text="center point" />
            <entry style="M.CITY HALL 3" text="cities" />
            <entry style="M.CITY HALL 4" text="big cities" />
            <entry is_separator="true" />
            <entry style="C.ROSY BROWN STROKE" text="state boundary" />
            <entry style="L.PH" text="interstate highway" />
            <entry text="County population:" />
            <entry style="V.COUNTY_POP_DENSITY" tab="1" />
          </column>
</legend>Does anyone know how to reduce the white space in the legend or some other way to avoid the overlap? (whilst still placing both note and legend in the SOUTH EAST corner)
thanks,
Ross.

Hi Ross,
I don't think you will be able to reduce the white space at the bottom, but there are some parameters on the legend that you can use.
1) In overlap situations you can set the transparency of the legend:
<legend bgstyle="fill:#ffffff;fill-opacity:128;stroke:#ff0000" profile="MEDIUM" position="SOUTH_EAST">
2) For the profile value there is an internal size defined. In your figure I can note that the advanced style items are also overlapping, which means that the internal size MEDIUM seems not appropriate for this legend. You can assign a height for a legend entry:
<entry style="V.CA INCOME 2" tab="1" height="150"/>
3) With version 11 there are two new parameters (location_x and location_y) for the legend that can be used to put the legend in any position. In this case the position attribute is ignored if defined.
<legend bgstyle="fill:#ffffff;fill-opacity:128;stroke:#ff0000" profile="MEDIUM" location_x="20" location_y="50">

OBIEE 11g Map View - Issue with Label Translation

Hi All,
I have a strange translation issue with the Maps in 11g.
Created in English language to plot the Revenue for each of the Postal Codes.
I selected Postal Code and Revenue Amount in the Criteria and created a new Map View. It had the text 'Postal Code' in the Map Legend and then the scale for revenue amount.
Now I logged on with Chinese Language , it still appears as 'Postal Code' in English where in it was actually supposed to show it in Chinese.
We have a translation pack to get all the column names translated. If I try creating a new table view, it shows the translated text instead of 'Postal Code', but some how this doesn't work with Maps.
Has anyone faced similar issues ? Is there a workaround for this ?
Thanks for any pointers.

Hi,
I also encounter the same issue. When I view combined layout, I get the No Results message. But when I edit the table layout, I see that there are records returned. Does anyone had any luck in resolving this issue?
Thanks!

Legend in manual mode - Background color

Hi all,
To create legend in manual mode I am using following request URL for a style image.
http://127.0.0.1:8988/mapviewer/omserver?sty=L.ROAD&w=20&h=20&ds=cescdatasource
Here if the color of style is white (For example white color line style) then it won't be visible. Can I set background color?. I need different background color instead of white.
Thanks,
Sujnan

Either set the background color for the MapDecoration or for the table in which you display the legend or both.
e.g. (modification of tutorial 36 Map Legend)
// get the container DIV and set the background color to light blue
var legendDiv = legend.getContainerDiv();
legendDiv.style.backgroundColor = "AliceBlue"; //color name may not work in all browsers
function buildLegend(baseURL)
var html = "<table *bgcolor='gray'* border=0> <tr><td><img src="+baseURL+"/omserver?sty=L.PH&w=45&h=20&ds=mvdemo></td><td> Highways </td></tr>" +
" <tr><td><img src="+baseURL+"/omserver?sty=M.CITY+HALL+3&w=20&h=20&ds=mvdemo></td><td> Cities </td></tr>" +
"</table>";
return html;
}

Embedded Legend in JSP file

I would like to embed my legend within my map request. I can display the legend on my page within a Table Row, but I would prefer it located inthe Southwest corner of my map image. Can this be done? I have seen it in XML done this way.
Here is my legend code as well as my map display code.
Thanks!
<tr><td><mv:makeLegend id="myLegend">
<legend bgstyle="fill:#ffffff;stroke:#ff0000" profile="SMALL" position="SOUTHWEST">
<column>
<entry text="Map Legend:" is_title="true" />
<entry style="M.GREEN" text="No Outages Reported" />
<entry style="M.RED" text="Outage Reported" />
<entry style="M.AMBER" text="Degraded Status Reported" />
</column>
</legend>
</mv:makeLegend>
<IMG SRC="<%=myLegend%>"></td></tr>
<tr align="center">
<td valign="top" align="center">
<input type="image"
border="1"
src="<mv:getMapURL />"
name="userClick"
alt="Click on the map for selected action">
</td></tr>

Hi,
you can't use the makeLegend tag to embed it on map, but you can add an API method on your jsp code to add the legend. This is an example:
<%@ taglib uri="http://xmlns.oracle.com/j2ee/jsp/tld/spatial/mvtaglib.tld" prefix="mapviewer"%>
<%@ page contentType="text/html;charset=windows-1252"%>
<%@ page import="oracle.lbs.mapclient.MapViewer" %>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
    <title>untitled</title>
</head>
<body title="MapViewer WebMap">
    <DIV align="center">
      <mapviewer:init url="http://stadb35.us.oracle.com:8888/mapviewer/omserver" datasource="mvdemo" id="mvHandle"/>
      <mapviewer:setParam basemap="density_map" width="600" height="450" antialiasing="true" title="My Web Map" centerX="-122.4" centerY="37.8" size="10"/>
    <%
      MapViewer mv = (MapViewer) session.getAttribute("mvHandle");
      mv.setMapLegend("<legend bgstyle=\"fill:#ffffff;stroke:#ff0000\" " +
                      "profile=\"MEDIUM\" position=\"SOUTHWEST\">\n" +
                      "<column>\n" +
                      "<entry text=\"Map Legend:\" is_title=\"true\" />\n " +
                      "<entry style=\"V.COUNTY_POP_DENSITY\" tab=\"1\"/>\n " +
                      "</column>\n " +
                      "</legend>");
    %>
      <mapviewer:run/>
    </DIV>
    <img src="<mapviewer:getMapURL />"/>

Legend in MapViewer

I'm modifying the provided demo-files wich are using the MapViewer-bean. Now I want to add a legend.
I can't find out how to do this.
In another demo-file is an example, but is using the tags.
Is there a way to create a legend without using the tags but with using the JavaBean?

Although it is possible to include a map legend specification in each and every xml map request,
currently there is no Java api that lets you do that. The JSP tag demo is simply submitting a manually created XML legend request and extracting the url to the legend image itself.
If you dont need a legend inside each map generated by mapviewer, you can simply pre-generate the map legend through a standalone XML request using one of the forms in the mapviewer homepage. Then save the generated image and place it somewhere in your final web page.

MapViewer Legend

Hallo,
I am dealing with mapviewer and the legend.
1: I can create a legend by defining each theme and the symbol I use for this. But is there a way that the legend is defined "automaticlly" so that I do not have to define each theme but mapviewer knows which themes are in this map and generates?
2: I can position the legend with position="NORTH_WEST". Are there other way to position it? By using numbers?
3: Are there code samples and where I could use?
4: I can not change the font of the text in the legend?
Thanks in advance Tig

Hi Tig,
Currently you can't generate the automatic legend based on the themes, and also you can't define a location (X,Y) to put the legend. We'll add these items on the enhancement list.
For item 4, MapViewer parses the legend font, however the API method setMapLegend does not have this parameter. We'll also add this enhancement. If you issue a XML request directly, you can define the font as:
<legend bgstyle="fill:#ffffff;fill-opacity:128;stroke:#ff0000"
          position="NORTH_WEST" font="Dialog">Next, is a sample of Java code to generate the structure to pass to the API method setMapLegend:
String [][][]legenddata = new String[1][][]; // legend with one column
legenddata[0] = new String[8][];    // column with 8 items
for(int i=0;i<8;i++)
    legenddata[0] = new String[5]; // description of each item
legenddata[0][i][0] = null; // text
legenddata[0][i][1] = null; // style
legenddata[0][i][2] = "false"; // is title
legenddata[0][i][3] = null; // tab
legenddata[0][i][4] = "false"; // is separator
// <entry text="Map Legend" is_title="true" />
legenddata[0][0][0] = "Map Legend"; // text
legenddata[0][0][2] = "true"; // is title
// <entry style="M.STAR" text="center point" />
legenddata[0][1][0] = "center point"; // text
legenddata[0][1][1] = "M.STAR"; // style
// <entry style="M.CITY HALL 3" text="cities" />
legenddata[0][2][0] = "cities"; // text
legenddata[0][2][1] = "M.CITY HALL"; // style
// <entry is_separator="true" />
legenddata[0][3][4] = "true"; // is separator
// <entry style="C.ROSY BROWN STROKE" text="state boundary" />
legenddata[0][4][0] = "state boundary"; // text
legenddata[0][4][1] = "C.ROSY BROWN STROKE"; // style
// <entry style="L.PH" text="interstate highway" />
legenddata[0][5][0] = "interstate highway"; // text
legenddata[0][5][1] = "L.PH"; // style
// <entry text="County population:" />
legenddata[0][6][0] = "County population:"; // text
// <entry style="V.COUNTY_POP_DENSITY" tab="1" />
legenddata[0][7][1] = "V.COUNTY_POP_DENSITY"; // style
legenddata[0][7][3] = "1"; // tab
mapViewer.setMapLegend("#ffffff","255","#ff0000","MEDIUM","NORTH_EAST",legenddata);
Thanks for your comments.

Web query using map

Hello all,
I would like your help on this:
I have created a web report which has 3 fields: region, the KF's qty and FOB$. Then I added the map item in it. When i run this query template, I see the first part with all the data; then i see the map of US below (not big) divided by the states but with no data or color. I have chosen 'bar' as the info display.
Now, how can I see the numbers(bar graphic) for each US state?
In the map legend, i can see the 2 KF's with different colors and the total overall qty as seen in the report.
The goal is to see the map of US and the bar graphic on top of every applicable state Please thanks for any help/tips/docs on this map creation via web.

Bucketstyle questions

Hello,
i have some questions regarding bucket styles in Mapviewer Ver1033p5_B081010.
I defined a collection-based bucket style with discrete values:
<?xml version="1.0" ?>
<AdvancedStyle>
<BucketStyle>
    <Buckets>
      <CollectionBucket seq="0" label="text1" type="integer" style="C.STYLE1">1</CollectionBucket>
      <CollectionBucket seq="1" label="text2" type="integer" style="C.STYLE2">2</CollectionBucket>
      <CollectionBucket seq="2" label="text3" type="integer" style="C.STYLE3">3</CollectionBucket>
      <CollectionBucket seq="3" label="text4" type="integer" style="C.STYLE4">4</CollectionBucket>
      <CollectionBucket seq="4" label="text5" type="integer" style="C.STYLE5">5</CollectionBucket>
      <CollectionBucket seq="5" label="text6" type="integer" style="C.STYLE6">6</CollectionBucket>
      <CollectionBucket seq="6" label="text7" type="integer" style="C.STYLE7">7</CollectionBucket>
      <CollectionBucket seq="7" label="text8" type="integer" style="C.STYLE8">8</CollectionBucket>
      <CollectionBucket seq="8" label="text9" type="integer" style="C.STYLE9">9</CollectionBucket>

      <CollectionBucket seq="11" label="text12" type="integer" style="C.STYLE12">12</CollectionBucket>
      <CollectionBucket seq="12" label="text13" type="integer" style="C.STYLE13">13</CollectionBucket>
      <CollectionBucket seq="13" label="text14" type="integer" style="C.STYLE14">14</CollectionBucket>
      <CollectionBucket seq="14" label="text15" type="integer" style="C.STYLE15">15</CollectionBucket>
      <CollectionBucket seq="15" label="text16" type="integer" style="C.STYLE16">16</CollectionBucket>
      <CollectionBucket seq="16" label="text17" type="integer" style="C.STYLE17">17</CollectionBucket>
      <CollectionBucket seq="17" label="text18" type="integer" style="C.STYLE18">18</CollectionBucket>
      <CollectionBucket seq="18" label="text19" type="integer" style="C.STYLE19">19</CollectionBucket>
    </Buckets>
</BucketStyle>
</AdvancedStyle>and a theme that uses this style:
<?xml version="1.0" standalone="yes"?>
<styling_rules key_column="ID">
<hidden_info>
    <field column="INFO_COLUMN" name="Info"/>
</hidden_info>
<rule column="GROUP_ID">

</styling_rules>
Problem 1:
I try to get the map legend using a map_request like described in LJ.Qians excellent blog: http://oraclemaps.blogspot.com/2008/10/generating-map-legends.html (approach 1).
The problem i have here is that i have to set a hight manually in the legend request, otherwise the text in the resulting legend image is too small to be readable. But when i change the bucket style to include more buckets (or less) i would have to change this height value to reflect that change. I would like to avoid this.
Setting the profile to "LARGE" does solve the problem, but when the legend includes some more styles from different themes those styles are too big in the legend image, and it looks inconsotent.
I tried the approach 3 full manual mode from the above mentioned blog, but again here i have to set the width and height of the resulting image.
To set the height automatically i would like to get the number of the buckets in the bucket style. Is there a request that i can send to the mapviewer server to get this number, or maybe a description of the style itself?
Problem 2:
As you can see in my theme definition i include a INFO_COLUMN in the hidden_info section part, so that i can use the theme as a clickable foi.
Normally i would expect that the info window that is opened upon a click on an element of this foi contains only this info column.
But it also shows the rule column for the feature style (GROUP_ID).
Is there a way to prevent this and only to show the INFO_COLUMN?
Thanks for help in advance,
Dirk

Hi Dirk,
1) You can send an info request and get the style definition. For example:
<?xml version="1.0" standalone="yes"?>
<info_request datasource="mvdemo" format="strict" >
            select definition from user_sdo_styles where name = 'V.CB1'
</info_request>the result is something like this, and you can parse the result to get number of buckets:
<?xml version="1.0" encoding="UTF-8" ?>
<ROWSET>
   <ROW num="1">
    <DEFINITION>
       <?xml version="1.0" ?>
       <AdvancedStyle>
         <BucketStyle>
            <Buckets>
               <CollectionBucket seq="0" label="a" style="C.BLUE">1.0, 2.5</CollectionBucket>
               <CollectionBucket seq="1" label="b" style="C.YELLOW">2</CollectionBucket>
           </Buckets>
        </BucketStyle>
      </AdvancedStyle>
    </DEFINITION>
    </ROW>
</ROWSET>2) The default info windows shows the info columns plust any attributes in your rule. But you can overwrite the info window default code.
Take a look at example 7 in Oracle Maps demos.
