Different map sources

Can i use a map from ArcGIS i.e ESRI shapefile

How do I use My own WMS Map Service? is it enough to use :

SimpleWMSMap wms = new SimpleWMSMap(
"http://iceds.ge.ucl.ac.uk/cgi-bin/icedswms?VERSION=1.1.1&SRS=EPSG:4326",
256, 0, 18,"bluemarble,cities,countries", "image/jpeg",
"default", "GetMap", "© UCL");
wms.setWidthHeightRatio(2.0);
mapComponent.setMap(wms);

Here, "bluemarble,cities,countries" are layers for maps, what should i have to do if i am using my own maps and lets say i don't know the layers. What is the default parameter to write?

I tried to implement with own wms maps but it says the following error:
1. msWMSLoadGetMapParams(): wms server error.
2. Invalid layer(s) given in the LAYERS parameter.

hi,

I'm using SimpleWMSMap, and able to set my Map.
can I give any value other than the default/"" for 'style' parameter,i.e., the seventh one in SimpleWMSMap constructor.

now I'm giving "" , I'm getting BIG letters on my Map. what shall I do to reduce the size of the letters?

Hi,

This is my URL that I am requesting:

http://ar22.arbonaut.com/cgi-bin/mapserv.exe?map=D:/webpages_taaka/taaka...

Thank You.

I tried following code, and it worked for me. Note that you must use EPSG:4326 and cannot use 3067 like in your example URL. Your server seems to support also EPSG:4326.


SimpleWMSMap wms = new SimpleWMSMap("http://ar22.arbonaut.com/cgi-bin/mapserv.exe?map=D:/webpages_taaka/taaka/wmscapabilities_matintesti_modis.map&VERSION=1.1.1&&SRS=EPSG%3A4326&SERVICE=WMS&",
256, 0, 18, "topo", "image/png","", "GetMap", "");

wms.setWidthHeightRatio(2.0);

map.setMap(wms);

Hi,

It worked for me.

Thanks

If I have a image and I know it's four corner coordinates, is there a chance to use it as a map? It is just a school project so I don't need something accurate.

ClujMap
The image is too big to be uploaded (about 10MB).
If I could send it to you on skype would be great. If it's just to put the maps on a local server, It doesn't matter their location (offline or online).
Thank you very much.

You can send it to skype user nutiteq. 10MB is too big bundling into application JAR, but it really depends on many factors.

I wrote to you on skype

Thank you

WOW!!!
I works!
You are realy great!
The only problem is that I don't know why is not loading all the tiles as you could see in the image:
Map

Anyway, it should be enough for the project I have. I appreciate your fast replys and I will recomend you wherever I'll have the oppurtunity.

Hi,
I can't use my own mapserver.

this my sample code.

package com.tutorial;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;

import com.nutiteq.MapItem;
import com.nutiteq.maps.*;
import com.nutiteq.components.WgsPoint;

import com.nutiteq.components.Line;
import com.nutiteq.components.Point;
import com.nutiteq.components.LineStyle;
import java.io.IOException;

public class HelloMap
extends MIDlet
implements CommandListener {
private Form mMainForm;
private MapItem mapItem;
private Image icon;

public HelloMap() {

mapItem = new MapItem("Map", "tutorial", this, 300, 400, new WgsPoint(69.3234345, 41.234423), 8);
mapItem.defineControlKey(ControlKeys.MOVE_UP_KEY, Canvas.KEY_NUM2);

mapItem.defineControlKey(ControlKeys.MOVE_LEFT_KEY, Canvas.KEY_NUM4);
mapItem.defineControlKey(ControlKeys.MOVE_RIGHT_KEY,Canvas.KEY_NUM6);

SimpleWMSMap wms = new SimpleWMSMap("http://217.29.118.23:8888/cgi-bin/mapserv.exe?map=f:/OSGeo4W/secure_maps/uzbekistan.map&VERSION=5.4.2&&SRS=EPSG%3A4326&SERVICE=WMS&",
256, 1, 15, "", "","", "GetMap", "");

wms.setWidthHeightRatio(2.0);

mapItem.setMap(wms);

mMainForm = new Form("Hello map");
mMainForm.append(new StringItem(null, "Hello, map!\n"));
mMainForm.append(mapItem);

mMainForm.addCommand(new Command("Exit", Command.EXIT, 0));
mMainForm.setCommandListener(this);
}
public void startApp() {
Display.getDisplay(this).setCurrent(mMainForm);
mapItem.startMapping();
// mapItem.addPlace(new Place(1, "Tashkent", icon, 69.3234345,41.334423));
}

public void pauseApp() {}

public void destroyApp(boolean unconditional) {}

public void commandAction(Command c, Displayable s) {
/* String label=c.getLabel();
if(label.equals("OK")){
mapItem.addPlace(new Place(1, "Tallinn", icon, 69.3264580, 41.237420));
}
*/
notifyDestroyed();
}

}

How can use my own mapserver?

In my project .
following error:
1. msWMSLoadGetMapParams(): wms server error.
2. Invalid layer(s) given in the LAYERS parameter.

I don't know how to set parametr layers.
What this parametrs mean?
Where I can take this parametrs?
Can you send me simples like that examples?

Hi?
I want to use my own map of a town.
It will be bundled with the application
How do i go about with it?

I have used mapcruncher but i still cant get to view the map,the size of the jar file is 1.12MB am only seeing a red image,i dont know what it might be the problem,anybody can help me figure out.

The size of my image is 23.3kb can i send it to you

Hello,
Can I display the shapefile which I added using Geoserver using hellomap example of MGmaps??

Really appreciate your help!
Thanks in advance!

Hi,
I have created shapefiles and displayed it using geoserver. Now, I need to access these layers(shapefiles stored in geoserver) using hello map midlet. How can I dot this..?

Thanks in advance!!

GeoServer has WMS API, so the "WMS map service" code snippet example above should give hint. You should just replace parameter values: server and layer names with your server's.

hi,
I created a shapefile called 'india shp' in geoserver. I need to view this using the hello map midlet. I tried to follow the "WMS map service" code snippet and my url is: "http://localhost:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&layers=india-shp&styles=&bbox=68.178,6.734,97.462,37.035&width=494&height=512&srs=EPSG:4326&format=application/openlayers"

but i get an error saying: cannot find symbol
symbol : class SimpleWMSmap
location: class com.tutorial.HellMap
SimpleWMSMap wms = new SimpleWMSmap("http://localhost:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&layers=india-shp&styles=&bbox=68.178,6.734,97.462,37.035&width=494&height=512&srs=EPSG:4326&format=application/openlayers",256,0,18,"india_st,india_water,india_natural,india_coastline,india_highway,india_ds","image/jpeg","default","GetMap","");
1 error

Can you please let me know the correct code to implement, and debug my error?
thanks in advance!!

Perhaps you have not added proper import to the class (import com.nutiteq.maps.SimpleWMSMap;)

i have added the import. it works now i am not getting any error.but..
I have posted a part of the code i used in my example below. The layers of my india-shp file are-india_st,india_ds,india_coastline,india_natural,india_water and india_highway.

code:
private MapItem map;
public HellMap() {
SimpleWMSMap wms = new SimpleWMSMap("http://localhost:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&layers=india-shp&styles=&bbox=68.178,6.734,97.462,37.035&width=494&height=512&srs=EPSG:4326&format=application/openlayers",256,0,18,"india_st,india_water,india_natural,india_coastline,india_highway,india_ds","image/openlayers","","GetMap","");
wms.setWidthHeightRatio(2.0);
map.setMap(wms);
}

can you please let me know if the code written above is correct?

And also, when i execute my example it doesn't give any error, the emulator opens but when i try to launch my application it gives me an exception saying- the application has unexpectedly quit. Contact the application provider to resolve the issue.

I am not able to display the map. I did keep my geoserver started and even tried giving the website address in the emulator but it still gives me the same exception. please tell me where am i going wrong.

thank u!!

Hello,

I and Anjana are working on the same topic. Even I am facing the same problem. I changed the Map size to 256 and used IP address as 127.0.0.1 but its still giving the same exception.

Thanks!

hello,
ya..i agree with shamitha.its still giving the same exception....please specify a solution to this problem....
thank u!

Hi,
I was trying to figure out why an exception saying-"the application has unexpectedly quit. Contact the application provider to resolve the issue." is getting displayed on an emulator. Then I thought may its because, I have not added the MG maps evaluation key. Can u please tell me where I should include this key.

Thanks in advance!!

Hi,
Thanks for the reply. I tried to take out the comment of the following instruction.
mapItem = new MapItem("Map", "eecca5b6365d9607ee5a9d336962c5344bc292103431f5.83161285", this, 300, 150, new WgsPoint(24.764580, 59.437420), 0);

Now, when i executed the code it dint show an exception but it dint display maps from geoserver.

Hi
i tried commenting out the lines as you have specified...but as shamita said, it does not display the map..and also, the emulator specifies whether to access the airtime or not..but since ours is an offline server we shouldn't be accessing the network..and even if we specify the 'yes' option,it displays a blank page with no map.

Can you please look at the code above and give us a solution...its a college project and we have to demonstrate the completed project next week. We have configured the server, understood the client side and tried it with online openstreet maps,but we need to integrate these two in order to complete the project....so...
thank you.....

hello again

i just needed to know whether we need to publish our geoserver on the internet in order to access the shapefiles present in them using the SimpleWMSMap constructor, for map display. i.e., do we have to put our geoserver on the internet using a domain name or iP address?and use this iP of the geoserver in our uRL provided in the constructor of the SimpleWMSMap?

thanks in advance!!

Hello,
The geoserver which we have configured has to run in offline mode in localhost. We have to access this using the hellomap application. We used the code for the simple wms map as mentioned above. But it is not working. We even tried giving ip address as 127.0.0.1. We also tried giving my computers ip address which accesses internet. But we keep getting an error saying "Network Error".

This is the code snippet:

mapItem = new MapItem("Map", "eecca5b6365d9607ee5a9d336962c5344bc292103431f5.83161285", this, 300, 150, new WgsPoint(24.764580, 59.437420), 0);
SimpleWMSMap wms = new SimpleWMSMap(
"http://172.16.0.207:8080/geoserver/wms?service=WMS&version=1.1.0&request=GetMap&layers=india:india_st&styles=&bbox=68.359,6.734,97.462,37.035&width=491&height=512&srs=EPSG:4326&format=application/openlayers",
256, 0, 18,"layer_st", "image/jpeg",
"default", "GetMap", "");
wms.setWidthHeightRatio(2.0);
mapItem.setMap(wms);

Can you please give us the actual code to implement this.

Yes. We use Java ME SDK version 3. It has emulator with CLDC configuration.
When we run the application on emulator, it shows network error, even though Geoserver is started.

Hello,
Solved the problem. Map is getting displayed in the emulator now. But the whole map is not getting displayed. In goeserver, when maps are displayed using openlayers, there is automatic zooming and panning on the displayed map. In midlet we have used png format so in emulator, panning works fine as we had coded in the hello map midlet. But we are not able to view the zoomed maps.
Do we need to use any other tool such as map- cruncher??

Thanks for the reply!!We have defined the action buttons for zoom in and zoom out. We have used zoom-in:KEY_POUND and zoom-out:KEY_STAR.
We have two problems:
1.Map is not getting loaded fast. So should we use RMSCache or streamed maps as a solution for this?
There is a caching technique in geoserver called GeoWebCache. GeoWebCache works as a proxy between your client(emulator) and GeoServer.
So in order to use this, it is specified that we have to use:
http://example.com:8080/geoserver/gwc/service/wms
instead of this:
http://example.com:8080/geoserver/wms

But when we used this in SimpleWmsMap constructor it is not loading the map, instead displays red tiles.
2.Zooming option is not working. When map is zoomed it gives blurred image rather than displaying subsequent layer details.

Can you please specify the solution for this.
