version 6.1

NOTE: This instruction only applies to imagery that was not acquired by the JRC under its annual LPIS QA campaigns. It therefore relates only to the aerial and other imagery that was independently acquired by the Member State for use in support of its inspection of the sample of reference parcels.


Step 1: Document the metadata

Prepare an entry for control zone and preparation of XML file according to the OrthoimagerySet.xsd, as available on the download article.

This xml-file is a part of the ETS reporting package

  • ZoneID of this xml is the identification of the zone, analogue to the LPIS QA zone naming and mostly linked to acquisition processes.

Step 2: Check format

Make sure your image is in one of the supported file formats for the image datasets.

  • GeoTIFF
  • ERDAS Imagine (HFA)
  • ECW

Convert or export your imagery to one of these three formats if needed.

If a compression method is applied solely for the purpose of transmission, it should be lossless only (for example LZW for GeoTIFF). Ideally, the uploaded or delivered orthoimagery should be in the same image format (same encoding and compression parameters) as used in the ETS.

Note: These considerations on conserving image quality also apply to the imagery made accessible via a web service.

Step 3: Organise your datasets/files per zone

Group all imagery produced in a single CRS that is relevant for a particular ETS reporting package (i.e. LPIS Authority/reporting year). Please note that

  • a dataset can be provided as a single large image file or as a mosaic of non-overlapping image tiles.
  • all image tiles of the same dataset must have the same coordinate reference system, else the zone needs to be split up in sub-zones.

To compile your complete dataset:

  1. Name the dataset: if you have sub-zones, create a unique ID for each individual dataset, otherwise use the LPIS zone ID;
  2. Create a folder with the name determined above;
  3. Place all files of the dataset (=same CRS,LPIS,year) into that folder;
  4. Place the XML file of step 1 in the folder and rename it to “lpis_ortho_meta.xml”

Step 4: Deliver

Deliver the compiled folder(s) either by FTP upload to the JRC server or by shipping DVD's:

  • FTP-upload: This requires the use of the FTP. Before any action:
  • indicate the approximate amount of data in GigaByte by contacting Slavko Lemajic (slavko.lemajic@jrc.ec.europa.eu),
  • ask for a credentials (valid FTP username and password) that will be shipped to you by e-mail Slavko Lemajic (slavko.lemajic@jrc.ec.europa.eu),
  • follow the file naming convention (following OrthoimagerySet schema version 6.1: OrthoimagerySet.xsd): reportingYear_lpisCode_zoneID_imageAcquisitionDate_platform_pixelSizeM_imageType.appropriateExtension.
  • For instance: 2013_TEST-LPIS_MZ03_2013-08-17_WORLDVIEW2_0.5_PAN-MUL-FCC-RGB.ecw


  • Shipping of DVD’s or hard disks: The shipping address is
Joint Research Centre
Directorate D - Sustainable Resources
D5 - Food Security, TP 266
Slavko Lemajic
Via E. Fermi 2749
I-21027 Ispra (VA)
Italy
Please inform this responsible person via mail about the shipment (mailto: slavko.lemajic@jrc.ec.europa.eu).

Aftermath

  • JRC will return harddisks if the MS provides a shipping address.
  • The imagery will exclusively be used for screening of the ETS observations by EC staff and will not be available through the CID portal for any other application.
