How to View Pleiades NEO (PNEO) Raw Data
Updated over 3 months ago

This knowledge base support document is relevant to users who have been delivered the raw version of a Pleiades-Neo product. This delivery will come directly from the support/solutions/success team at SkyWatch and will only occur if an order has experienced an issue delivering the data, or for specific requests from HUB user accounts.

To view the raw data, GIS software such as QGIS or ArcGIS needs to be installed onto a user’s computer.

View Using QGIS

  1. If not already installed, install the most recent version of QGIS to correctly view this image: https://www.qgis.org/en/site/forusers/download.html
    ​
    ​

  2. Starting with the unzipped file, make sure that you do not rename or move any files within the PNEO folder structure.
    ​
    ​

  3. Navigate to the folder named similar to IMG_01_PNEO4_MS-FS
    ​

  4. Within the IMG_01_PNEO4_MS-FS folder, drag and drop the .XML file starting with ‘DIM_PNEO...’ in to the main QGIS window. For example: “DIM_PNEO4_202301180812429_MS-FS_ORT_f563bfc0d54e4ecacec12cbda38985cb.XML”
    ​

  5. This DIM file will automatically load all the associated TIFF files.
    ​

  6. The entire image, with all tiles assembled, is then rendered in QGIS. The metadata will also be associated with the image. If only a black and white image is showing, the incorrect file was most likely dragged into QGIS.
    ​
    ​

  7. If you check the Layer Properties you can see all of the 6 available bands. You can then change which bands are currently displayed. Layers Pane > Right-click image > Properties > Symbology tab
    ​

  8. If required, you can then export the image as a single tiff file:

  • (a) In QGIS, right-click the image in the Layers Pane > Right-click image > Export > Save As

  • (b) In the “Save Raster Layers as” window select Raw data to create a tiff file which include all of the original bands (16-bit) and pixel values or Rendered Image to save a smaller 8-bit RGB image.

View Using ArcGIS

  1. If not already installed, install the most recent version of ArcGIS software: https://www.esri.com/en-us/arcgis/products/arcgis-online/trial
    ​
    ​

  2. Starting with the unzipped file, navigate to the folder and make sure that you do not rename or move any files within the PNEO folder structure.
    ​

  3. Open ArcGIS, create a new project, and add the location of the folder containing the unzipped Airbus data, to the project.
    ​

  4. If the data is already pansharpened, import the XML file.
    If the data is not already pansharped (as shown in the screenshots), locate the panchromatic and multispectral data in the following folders:
    Multispectral data: IMG_01_PNEOX_MS-FS folder and DIM_PNEO.....XML file
    Panchromatic data: IMG_01_PNEOX_PAN folder and DIM_PNEO.....XML file
    ​

  5. Add the XML file to a new Map,
    For example "DIM_PNEO4_202209290911529_MS-FS_ORT_4393d19040204a2dcafbb3c53edc01f3.XML"
    ​

  6. (Optional) Pansharpen or overlay the multispectral layer, on to the panchromatic layer for better resolution:
    ​

  7. Export the image in the file format of your choice.
