MapViewer in the UK

Hi
I have been tasked with writing a document on Oracle MapViewer and am trying to find examples on the Internet of the application's use in the United Kingdom that I can include in my report.
Does anyone know where I can find any?
Thanks.
Vinesh

Vinesh,
There is a very active Spatial SIG in the UK. Take a look at http://www.ukoug.org/communities/show_community.jsp?id=21&parent=811 and contact Robert Southern.
There have been 4 presentations - 2 by users Portsmouth University and BT - 2 by Albert Godfrind.
I hope this helps.

The Oracle MapViewer brings the WebLogic Managed Server to crash

Problem Description: The Oracle MapViewer brings the WebLogic Managed Server to crash, when we call a GetMap-Request with wrong Coordinates.
This was found out for the SRS=EPSG:25833. Example:
http://igdb-qm-svra1.blva.bayern.de:8080/mapviewer/wms?
REQUEST=getMap&
Version=1.1.1&
LAYERS=&
FORMAT=image/png&
TRANSPARENT=false&
STYLES=&
Datasource=igvert_alkis_wms&
basemap=AT_WMS_TN-KOMPLETT&
SRS=EPSG:25833&
BBOX=3.32358690717E7,5529425.0143,3.32369088846E7,5530464.8272&
WIDTH=500&
HEIGHT=500&
With the Enterprise Manager was also evaluated during and after a crash of Server the SQL-Statements.
If the SQL statements executed on the database itself, it takes a few seconds after a correct answer returns.
I know that have the look for the EPSG coordinate as follows:
BBOX=235869.071700,5529425.014300,236908.884600,5530464.827200&
My question therefore: Why are these coordinates by the Oracle MapViewer approved and not caught? An Request with incorrect
coordinates goes into a StuckThreads and then the ManagedServer crashed.
In the appendix you will find the evaluation of the Enterprise Manager.
I have tested the request with two different versions of Oracle MapViewer (Ver11_1_1_5_B110527 and Ver11_B100426). In both the same problem occurs on.
I have also filed an SR.

Geolocation MapView- Customizing the Map

I currently have a list that contains a Geolocation type column, and a defaulted map view.
Is there a way to change the map type to be aerial view all the time? Currently, it looks like it is on auto, and map types changes according to the zoom level.
I'd greatly appreciate any help. Thank you.

Hi,
Do you mean you want to restrict map scale to be permanent?
If that is the case, you might disable mousewheel zoom on map:

Using the mapViewer for multiple markers

Hello, I am using a visual jsf project and the mapViewer in NetBeans.What I want to do is add multiple markers on the map, but I am new to this so I wanted to know if someone knows how to do this.Is there a good tutorial for more complex use of the mapViewer?I have looked in google but all there is about mapViewer is the tutorial from the NetBeans page which is very simple.Any help would be appreciated thank you!

Hi SqlCraze,
I also design the report using Report Designer. So you can directly do the same steps as I post.
In the fourth step that "Insert the corresponding fields to the second table" means directly insert State, ACount, BCount and Description fields. Please note that the list control is used to split one table into several tables based on the
Description group: one table only displays the values when Description=Category1, one table only displays the values when Description=Category2, another table only displays the values when Description=Category3. We needn't add filters in the table, just add
the list.
For more information about the list control in Reporting Services, please refer to the following blog:
http://blogs.technet.com/b/microsoft_in_education/archive/2013/03/09/ssrs-using-a-list-item-to-display-details.aspx
If there are any other questions, please feel free to ask.

My oc4j is error while I operate the mapviewer again, why?

when I zoom out or zoom in the mapviewer client,the map appearance is very slowly, and some layers are not appeared,why.
start the mapviewer for the first,the OC4J are all right,
but after operating to the mapviewer again,
the OC4J tips are following this:

thank you very much!

You should check your shared_pool_size and java_pool_size
parameters on the database.
This error occurs when these are not set high enough.
Increase their size and restart the db and try the
mapviewer again.

Using MapViewer from PL/SQL vs Java

Hi group!
The MapViewer User's Guide has this to say about using MapViewer from PL/SQL:
"The usage model for the SDO_MVCLIENT package is almost identical to that of
MapViewer JavaBean-based API" etc etc .. "For usage and reference information about specific functions or procedures, see the description of the associated JavaBean-Based API. methods and interfaces in Chapter 4"
If I don't misunderstand the basic concept, in a Java Web App (using the MapViewer Bean) you create a MapViewer object for each HTTP-user-session, like so:
MapViewer mv = new MapViewer("http://my_corp.com:8888/mapviewer/omserver");
... which you would then store in the user's session object, so that the MapViewer Bean conveniently holds the map's state on the user's behalf.
To do the equivalent in PL/SQL, the User's Guide suggests:
"connect scott/tiger
call sdo_mvclient.createmapviewerclient(
'http://www.mycorp.com:8888/mapviewer/omserver') ;
The preceding example creates, in the current session, a unique MapViewer client
handle to the MapViewer service URL"
Does "current session" refer to the HTTP-user-session? While I've used PL/SQL before, I've not used the PL/SQL Web Toolkit. Is the session handling implicit here (and invisible?) or should the sdo_mvclient be subsequently stored in the PL/SQL equivalent of a (J2EE) HttpSession object?
YT

Part of the answer will depend on how you plan to deploy the application. If you have a few, local clients you could go with the traditional client/server model. If you have a lot of clients and/or they are spread out over a relatively large area (like a campus setting), a web front-end will save you a lot of hassels down the road when it comes time to upgrade.
Regardless of the the front end, I can tell you that I have been greatly impressed with the throughput you can get by moving most of the code to PL/SQL packages. A few years ago we reworked a VB/Oracle app by moving a lot of the code out of VB and into packages, leaving the client to essentially call procedures and format the output. We had more than a 3x performance increase on the same hardware and our network utilization decreased noticably.
I am now in the process of replacing the client code with Java servlets/JSP, primarily because of the maintenance hassles I mentioned earlier. There are some limitations with an HTML page but most of these have been cosmetic so far.
We are still relying heavily on PL/SQL packages. The servlet code basically gets a request, calls a package to get the data, then hands the results to a JSP page. The JSP then formats the output and sends it to the client. We are little more than halfway through the re-write, but it appears performance will increase again. Not as noticably as before, but I will take what I can get. As you have seen, once something is rolled out it always ends up getting used more than you anticipated. Better to over-engineer now than have to patch it once it is live.

How to use mapviewer extension for jdevelop?

I am working on the mapviewer. But my problem is that I can not connect mapviewer, or I can not start mapviewer using the embedded oc4j by jdeveloper. In mapviewer faq I read that:
"How do I view the mapping metadata through JDeveloper's Connections Navigator?
We have developed an Oracle JDeveloper extension that lets you browse the available list of styles, themes and basemaps defined in a datasource through JDeveloper's Connections Navigator. To do this, you will first need to download the mvconnection.jar file from OTN's MapViewer site. This jar contains the code that defines a MapViewer connection type for JDeveloper. To install, simply drop this jar file to the JDeveloper extension directory, normally $JDEV_HOME/jdev/lib/ext. Then restart JDeveloper, and you are all set.
But when I restart jdeveloper, I got the message:
"H:\Programme\jdev\jdev\lib\ext\mvpalette.jar!\META-INF\jdev-ext.xml

I use Jdeveloper 10g. Have you ever met the same problem?
Thanks in advance

The Map Viewer extension is still not available for JDeveloper 10g. It works with JDeveloper 9.
The Mapping group is currently working on an upgrade.

Case Issue in Mapviewer WMS GetMap request

I've been working with Mapviewer 10.1.2.0.2 for a couple weeks now and have used the wms_getmap_request using the XML API to get layers from various WMS servers including USGS. I am interested in getting images specifically from wms.jpl.nasa.gov as they seem to have better global coverage than USGS which is primarily interested in the US. I believe that the wms.jpl.nasa.gov is a non compliant WMS server because the REQUEST=GETMAP name pair in the url created by Mapviewer using the wms_getmap_request fails while using REQUEST=GetMap works.
Here's and easy test: The URL in Example 1 fails while the Example 2 URL returns an image.
Short of asking Nasa's Jet Propulsion Laboratory to get a new wms image server, is there a workaround for this that would force the url request to use the mixed case version of the value instead of the all upper case? From what I can tell they are a leading source of this kind of information.
Example 1:
http://wms.jpl.nasa.gov/wms.cgi?VERSION=1.1.1&REQUEST=GETMAP&SRS=EPSG:4326&BBOX=-123.3865,367766,-121.1365,38.2766&WIDTH=600&HEIGHT=400&FORMAT=image/jpeg&BGCOLOR=0xffffff&TRANSPARENT=true&LAYERS=global_mosaic&STYLES=pseudo_bright&EXCEPTIONS=application/vnd.ogc.se_inimage
Example 2:
http://wms.jpl.nasa.gov/wms.cgi?VERSION=1.1.1&REQUEST=GetMap&SRS=EPSG:4326&BBOX=-123.3865,36.7766,-121.1365,38.2766&WIDTH=600&HEIGHT=400&FORMAT=image/jpeg&BGCOLOR=0xffffff&TRANSPARENT=TRUE&LAYERS=global_mosaic&STYLES=pseudo_bright&EXCEPTIONS=application/vnd.ogc.se_inimage
Thanks,

Hi,
Since MapViewer is a component of Oracle App Server, any MapViewer patch will have to be part of an App Server-wide patch, which is out of the control of the Mapviewer team (schedule wise).
We are however preparing for an early access release of MapViewer 11g, which will be available for download on OTN late Janurary 2006. That version will fix this issue (and also provides a ton of exciting new features).
In the mean time, if you contact me directly we can probably help you on this issue now. [email protected] please replace _ with . for the correct email adderess.
thanks

How to use a standalone mapviewer in JDeveloper

Hello everybody,
I want to use a standalone MapViewer (deployed in a standalone OC4J from MapViewer Quick Start) in JDeveloper.
How can i do it?

First of all thanks a lot for your interest !
What i want to do is to create a jsp page which will use the JSP tag library of Mapviewer.
The problem appears when i try to run a jsp page in JDeveloper which contain (for example) the init tag.
To be speceific i try to do what is described in the following link with the difference that i use a standalone mapviewer

Hardware Sizing for Oracle Application Server and MapViewer

Hi all,
I need to develop an application using Oracle Application Server 10g and MapViewer. The applicaction will, basically, do thematic maps based on a search criteria. The estimative is that we will have 25 users simultaneously using it.
I´d like to have an idea about the hardware to support it.
Do you know where I can get this information?
Any documentation can help.
Regards,
Luis Augusto

Hi Luis,
It may depend on your database size, but I think at least you need to meet the minimum requirements for the Application Server. You can find additional documentation for the AS at http://www.oracle.com/technology/products/ias/index.html.
However I would suggest some extra memory, and if possible the better CPU that you can get. MapViewer will render the spatial features on the server side, and depending on your database size and number of features returned from the queries, this extra memory will help.

Viewing raster data in mapviewer

I'm having some trouble with viewing raster data through oracle mapviewer.
The raster data is already in the database, I have not loaded it in with mapbuilder, and don't want to have to load it in again.
I've following the step suggested which were:
- georeference the data
-create the spatial extent
- created a row in the user_sdo_geom_metadata table
- created a spatial index on the spatial extent of the georaster table.
I have created a theme for it in mapbuilder, but get the error below when I try to preview it. Anyone any ideas?

Did you create pyramids for your GeoRaster? You may be exceeding some limits for the LOB, and you should create the pyramids. Returning a huge block image to display may not be appropriate and is not effective in terms of performance and memory use.

Thank for the quick reply. I was just doing a basic test to determine if Map Viewer would satisfy our target architecture and rich web client functional requirements. Everything checks out except for my lack of understanding on how to determine the best performance settings. I expect the development environment to be slower than production. Our actual production environment is many load balanced map and database servers.
Sorry about the lack of details.

Best practice GeoRaster and MapViewer?

Hi,
I want to see rasterfiles with using Oracle GeoRaster and MapViewer. I've bineary rasterfiles and aerial photographs(24 BIT).
Until now I put the data with following parameters into the database:
-     Oracle_inverleaving_type: BSQ
-     Oracle_raster_tile_size_x und -y: 2048
-     Oracle_compression: DEFLATE
-     Oracle_pyramid_max: null
-     Oracle_raster_pyramid_resampling: NN for bineary data and CUBIC for aerial photograph
The bineary rasterfiles could have about 15000x15000 pixels and the aerial photographs about 4000x4000 pixels.
For the MapViewer configuration of a GeoRaster-Theme I use pyramid-level NULL for aerial photographs and 1 for bineary pictures.
The MapViewer BaseMaps has a tilesize of 256x256 pixels and as format png.
Has anybody experience to get the best performance and best quality to show rasterfiles?
Regards,
Sebastian

Hi Jeffrey,
further I have the problem that the MapViewer (Ver1033p5_B081010) doesn't render maptiles for all zoom-levels with my posted settings. Before the MapViewer P5 exists an I use this version, I rendered the maptiles witch MapViewer of version P3.
With the latest version of mapviewer it is only possible to rendere maptiles up to zoom-level 3 and then (level zwo, one or zero) it doesn't render this tiles. The mapviewer shows the following error:

Question re: MapViewer and Network Model functions

Hi all,
Quick question re: MapViewer and it's support for the Network Model and the shortest-path functions. If I create a base map with a network theme based on my (large) network, and then use a jdbc_network_query on the same network to do some shortest path analysis will MapViewer use the (hopefully) cached copy of the Network to calculate the shortest path? i.e can I expect good response times once the cache is warmed up?
Thanks,
Steve

Hi Steve,
MapViewer uses the Network Java library to run the shortest path algorithm. This library is independent of the MapViewer cache, and also not thread safe. So for now the network is always loaded. The load time may be reduced if the request has a MBR, but it is not the ideal solution. There is a working going on, and we hope to avoid this load in future versions.
Thanks.

How do I use OracleMaps Javascript API from a different host than MapViewer

Hello,
I have successfully set up the Mapviewer quick start 10131, and am able to view the sample page showMap.html perfectly. I would like to run this same sample on a different server than where Mapviewer is installed. Let say mapviewer is installed on jstraub-winsvr:8888 and I want to run showMap.html from jstraub-linux1:7777. I tried changing the function showMap and the location to oraclemaps like the following:
<script language="Javascript" src="http://jstraub-winsvr:8888/mapviewer/fsmc/jslib/oraclemaps.js"></script>
function showMap()
var baseURL = "http://jstraub-winsvr:8888/mapviewer";
var mapCenterLon = -122.45;
var mapCenterLat = 37.6706;
var mapZoom = 4;
var mpoint = MVSdoGeometry.createPoint(mapCenterLon,mapCenterLat,8307);
var mapview = new MVMapView(document.getElementById("map"), baseURL);
mapview.addBaseMapLayer(new MVBaseMap("mvdemo.demo_map"));
mapview.setCenter(mpoint);
mapview.setZoomLevel(mapZoom);
mapview.display();
Now when I try running this page on jstraub-linux1:7777 I get a Javascript error, and in Firebug, I can see that there are request like the following:
POST: http://jstraub-linux1:7777/mapviewer/ReturnLocaleOper
GET: http://jstraub-linux1:7777/mapviewer/mcserver?xml_request=%3C?xml+version=%221.0%22+standalone=%22yes%22?%3E%3Cmap_cache_admin_request%3E%3Cget_client_config+map_cache_names=%22mvdemo.demo_map%22+format=%22JSON%22/%3E%3C/map_cache_admin_request%3E
Obviously those requests are bogus since mapviewer is at jstraub-winsvr:8888 and not jstraub-linux1:7777, I just want to run the page from jstraub-linux1:7777. Anybody know how I do this?

I believe that I am having the same problem. While I don't yet have a resolution, I do have a bit more information that may be useful. I have examined the oraclemaps.js script file and found some relevant references to the Javascript document.location object. As I watch the script execute, it seems that the author has made the assumption that the page served to the user has been served from the same Oracle Application Server running MapViewer. I have listed the lines that contain references to document.location below. (The line numbers may be off by a line or two as I have made some minor changes to facilitate my investigation.)
Line 742 : //_f16._f104="http://"\+document.location.host\+"/mapviewer/foi";
Line 6280 : var x2=String(document.location);
Line 10270 : var x40=String(document.location);
By changing line 742 to...
f16.f104="http://mymvserver:8888/mapviewer/foi";
...I believe I have the script looking in the right place. (Previously, it had been looking for /mapviewer/foi on the server that originally served the page.)
The x2 variable (at line 6280) seems to provide the current document location as a means to determine the MapViewer URL. Once again, the author seems to presume that MapViewer is found on the same server that originally served the page.
this._f53=x2.substring(0,x3\+x5\+2)+"/mapviewer";
I changed this line to read:
this._f53="http://mymvserver:8888/mapviewer";
Having made these changes, I have moved past the "object not found"-types of errors I had been getting. I now get "Permission Denied" errors which, I am thinking, may be the result of cross-site scripting problems predicted by the previous poster.
So, my question is this: Is it really expected that the page that integrates the map display must be served by the same Oracle Application Server instance on which MapViewer is running? This strikes me as an absurd limitation, so I assume it is not the case. Indeed, there is a post on this forum by another user who claims to have written an ASP.Net application that uses the Javascript interface to integrate MapViewer and the map display ( Link:securing mapviewer ). This is precisely what we are trying to do; but I have yet to determine how to go about doing it.
Can this be done? Is there any documentation that describes how to accomplish this?
