Import IKONOS into Stereo Analyst for ArcGIS

Dear all,

 

I need some help to understand how I can load IKONOS imagery into SAfA.

 

I downloaded one IKONOS stereo pair right from the Digital Globe website to test the importing process in SAfA.

 

The importing process recognizes the metadata file correctly:

 

1.PNG

 

In the next step the image appear in the list but Int. and Ext. boxes are in red colour:

 

2.PNG

 

When I click any of these boxes I get the error you see in the screen capture.

 

Does anybody can help me to identify where the problem is?. I read in the manual that I can do this process.

 

Every IKONOS image comes with its corresponding metadata txt files. How do I create a stereo pair if the importing process only read one image at a time?.

 

Thanks a lot for you help!

Re: Import IKONOS into Stereo Analyst for ArcGIS

Hello Santi,

 

I tested importing different IKONOS stereo data to SAfA. And it imports stereo pairs successfully, 2 images, not a single image. IKONOS stereo pairs are defined by a <po>_metadata.txt file containing references to images. Do you see “Stereo Mate File Name” in the <po>_metadata.txt file? If so then please submit a service ticket and we will analyze the issue.

Re: Import IKONOS into Stereo Analyst for ArcGIS

Hi Yasemin,

 

Thanks a lot for the infromation and your help.

 

No, I don't see "Stereo Mate File Name” in the metadata text file... I was testing this data-set provided by Digital Globe:

https://www.digitalglobe.com/resources/product-samples/geo-geostereo

 

I can't find any other IKONOS stereo sample data online. I don't really know if this sample data has the right format to be inported into SAfA.

 

Do you know of any other IKONOS stereo sample available?.

 

I tested the importing procedure for other Digital Globe sensors and it works like a charm.

 

Thanks again,


Santi

Re: Import IKONOS into Stereo Analyst for ArcGIS

Hello Santi,

 

The metadata file should be in the right format. The metadata should contain Stereo Position and Stereo Mate File Names.

Re: Import IKONOS into Stereo Analyst for ArcGIS

Thanks Yasemin,

 

I understand I don't have the proper metadata files.

 

Do you know of any IKONOS stereo sample available?. I just want to be sure that it works well.

 

Thanks a lot,

Re: Import IKONOS into Stereo Analyst for ArcGIS

Hello Santi,

 

Metadata file is a text file and you can edit the component metadata section and include Stereo Position and Stereo Mate File names. We will submit a support ticket for this one and I will help you edit the metadata.

Re: Import IKONOS into Stereo Analyst for ArcGIS

Thank you so much Yasemin,

 

This is really important to us!

 

Please find attahed in this message the metadata files I can find in the images folders for the IKONOS stereopair:

 

Folder structure of the IKONOS exaple is as follows:

 

\StereoPair\---------------------------------------- Root Folder

\StereoPair\po_1469762_0000000\---------- first image folder

\StereoPair\po_1469762_0010000\---------- second image folder

 

Inside every image folder I can find the file po_1469762_metadata.txt, The content of this file is exactly the same.Includes infromation of the stereo pair: AOI, images information, etc.

 

Inside every image folder I can also find the RPC infromation of every image:

po_1469762_rgb_0000000_rpc.txt

po_1469762_rgb_0010000_rpc.txt

 

I hope you can help me identify what I'm doing wrong.

 

Best regards,


Santi

Re: Import IKONOS into Stereo Analyst for ArcGIS

Hello Santi,

 

I replied to this from SFDC, ticket: 00020880. I sent you the edited file via email.

 

Here is what I did to make it work:

  1.  Images should be in the same folder. I copied the imagery from  folder po_1469762_0010000 to folder po_1469762_0000000. Copy all data but skip the existing data.
  2.  I opened po_1469762_metadata.txt file in an editor and made following changes in Product Component Metadata section.
    1. Changed Component ID: 0000000 to Tile ID: 0000000
    2. Changed Component File Name to Tile File Name
    3. Changed Component Geographic Corner Coordinates to Tile Geographic Corner Coordinates
    4. After forth corner added lines: 
      1. Stereo Position: Right
      2. Stereo Mate File Name: po_1469762_rgb_0000000.tif
    5. I made the same changes for Component ID: 0010000. Note that Stereo Position should be Left for the second image 

 

Best Regards,

Yasemin

Re: Import IKONOS into Stereo Analyst for ArcGIS

Hello,

 

I just wanted to let you know that I managed to properly import the Ikonos data-set.

 

The error was related to the Windows "regional settings". 

 

I changed the format to English (US) and everything works now...

 

Thanks to Yasemin, Dan and María for your help.

 

Best regards,

 

Santi
