Load online map

I want to load online map using SNAP,but I don’t know how to do it! urgently needed, thank you all.

Good morning Zellar,

what do you understand under “online map”? Do you want to use WMS-Services?

Best,
Andreas

If you want to use a Web Map Server the Layer Manager is your friend.

Dear Marco Peters,

Thank you very much for your reply.
But I don’t have the option “Image from Web Map Server (WMS)” in layer manager layout. Do you know how to solve this problem?

Thank you again.
Looking forward to your early reply.

yes, I do want to use WMS-Service. Could you help me?

Probably the data you are using is not geo-referenced.
What kind of data are you using?

SAR data and the corresponding optical data, for example, Google map, Baidu map, et… Do you think it is suitable?

I don’t know how you can use Google map or Baidu map. If they provide a WMS it might work.
Is the boundary of your SAR data shown in the World View. Or do you see lat/lon coordinates in the status bar at the bottom of SNAP?

Yes, the SAR data I am using show the boundary and the lat/lon coordinates are shown in the status bar at the bottom of SNAP, but there are no “Image from Web Map Server (WMS)” option. I’m confusing about it, please help me.

I want to upload online map using the software SNAP as you said “add layer” option, I input the map link, but there appears errors. I don’t know how to solve this problem.

It seems that SNAP can’t process the answer from the server.
Maybe you get an indication why it fails if you first reproduce the error and then go to the menu (Help / Show Log Directory) and open the messages.log file in a text editor. And the end you might see a more exhaustive error message.
Can you post the URL you are using?

Thank you for your reply. But I can’t find the menu (Help / Show Log Directory) .

I input the WMS url: http://www.skylab-mobilesystems.com/en/wms_serverlist.html, according to https://seadas.gsfc.nasa.gov/help/visat/LayerManagerWindow.html. But it didn’t work either. I don’t know why. Looking forward to your early reply, thank you so much again .

Now I see that you are still using a very old version.
Please download the latest version we provide here.

The second problem is that you can’t enter the HTML web page here. This web page simply lists possible web mapping server. But it seems that the list is outdated and most of the entries don’t work any more.
The following pages list available server.
WMS servers for use
Finding OGC WMS, WFS, WCS services
Not all do work too.
It’s not easy to find good WMS.

Dear Marco,

Thank you for your reply.
But the URL you provided cannot be used either and the screeshot is in the attached file. I still couldn’t get the answer.

Looking forward to your early reply.

Sincerely,
Juanping

This (http://129.206.228.72/cached/osm?Request=GetCapabilities) is a link to a server which you can use.
These pages also list available server.
WMS servers for use

A post was split to a new topic: Export the positon information of each pixel

It seems that some of the problems we have with the WMS are related to an old library (GeoTools) we use.
I’m currently updating our software to the latest version. So the behaviour in the next release is probably better.

Okay, thank you very much~
But what time could a new version be used by users?
I want to add web maps, such as bingmap, baidumap, etc. as a separate image layer to help SAR image understanding by using the new SNAP version.

Looking forward to your early reply and the new products.
Thank you again.

Hi marpet,
I want to add this WMS service: http://idena.navarra.es/ogc/wms
The server web is https://idena.navarra.es/Portal/Servicios
How I can do it?
Thank you

MIKEL

I think the service is not working. Because in the responds it says “java.lang.NullPointerException null”.
So you can’t add.
If it would work properly you can do it as I have written earlier:

<?xml version="1.0" encoding="UTF-8"?>
<ows:ExceptionReport xsi:schemaLocation="http://www.opengis.net/ows http://idena.navarra.es/schemas/ows/1.0.0/owsExceptionReport.xsd" version="1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ows="http://www.opengis.net/ows">
<ows:Exception exceptionCode="NoApplicableCode">
<ows:ExceptionText>java.lang.NullPointerException null</ows:ExceptionText>
</ows:Exception>
</ows:ExceptionReport>

Ok,
So the problem is the server’s URL no my SNAP.
Thank you

MIKEL
