For Firefox, Google Chrome and Safari, it is recommended that a recent version should be used if possible.

What Data are Available?

ESA is an International Co-operator with USGS for the Landsat-8 Mission. Data are downlinked via Kiruna and Matera (KIS and MTI) stations whenever the satellite passes over Europe, since November 2013. Typically the stations will receive 2 or 3 passes per day each and there are some new scenes for each path, in accordance with the overall mission acquisition plan.

The Neustrelitz data are instead available on the portal from May 2013 to December 2013.

Data are processed to either L1T or L1Gt product format as soon as they are downlinked. The target time is for scenes to be available for download within 3 hours of reception.

1. Creating an Account

You can search for and browse the data openly, but you will need an account to download the full product scenes.

If you do not already have an EO Sign In personal account, instructions to create one are available here.

2. Searching for Data

2.1 Searching for Data by Name/Station Name

- Click on the Search Tab
- Enter a full or part scene or Station Name (MTI or KIS) into the NAME Field
- The naming convention is LC8[path][row][year][day-of-year][station][version], e.g. LC82030232013212NSG00 for path 203, row 023 on day 212 of 2013, so any of these terms will match.
- Click Search

In the Results Tab, all data that have been received and processed from NSG will be displayed.

2.2 Search by Cloud Coverage

- Click on the Search Tab
- In the Cloud Coverage > Percentage field enter 10
- Click Search

In the Results tab, all scenes that have a Cloud Coverage of less than 10% will be displayed.

2.3 Search by WRS2 Path/Row

- Click on the Search Tab > Grid and you will find two fields, "Path" and "Row"
- To search for a scene that is in WRS2 path 171 and row 021, enter 171 into "Path" and 021" into "Row"
- Click Search

2.4 Search by Area of Interest

- Click on the Search Tab > Area Of Interest
- Select the shape that you want to search with by clicking on the dropdown arrow next to "Add Rectangle"
- Draw the required shape on the map and click Search

2.4.1 Tools > Merge

This can be used to merge two overlapping Areas of Interest that have been marked on the map, for example:

- Define two rectangular Areas of Interest on the map which overlap
- Then use Tools > Merge to combine these into one Area Of Interest
- Search on the resulting single area

2.4.2 Tools > Convex Hull

This is loosely related to the Merge Tool, except it offers the functionality to join "Multiple Non Overlapping Areas Of Interest" defined on the map.

If a user defines several Rectangular Areas Of Interest on the Map that are not overlapping, the user can go to Tools > Convex Hull which will create a minimal unique set of points containing X, with X being the defined multiple Areas Of Interest.

For example:

- Using the Add Rectangle Option, draw a Square over the UK
- Draw another Square over Spain
- Go to Tools > Convex Hull

This will create 1 new Area Of Interest, a rectangular strip covering from the UK down to Spain.

2.5 Search by Area of Interest using a ShapeFile

To upload a shape file to the Landsat 8 Portal to search on Area of Interest, the shape file must be packaged in a .zip prior to uploading it to the portal.

- Click on the Search Tab > Area Of Interest.
- Select dropdown arrow next to "Add Rectangle" and select "Add from File".
- Browse to the shapefile that you want to upload. Please note that the shapefiles must be packaged in a .zip file for the upload to work.
- Click Upload.
- Click Done.
- The uploaded shape will now be displayed on the map.
- Click Search to display the results that fall within the shape that has been uploaded.

2.6 Search by Date

- Click on the Search Tab > Date and you will find two fields, "From" and "To".
- Click on the field "From" and select a start date from the calendar.
- Click on the field "From" and select a end date from the calendar.
- Click Search.

2.7 Search by Period of Year

Search by Period Of Year is a search between 2 dates without specifying a year. For example: a search from Jan 1 to Jan 31 will retrieve all products acquired in January for every year.

- Click on the Search Tab > Period of Year and you will find two fields, "From" and "To".
- Click on the field "From" and select a start date from the calendar.
- Click on the field "From" and select a end date from the calendar.
- Click Search.

2.8 Add Product to Set

Landsat-8 Portal supports the overlay of quicklooks onto the map. After performing a search, quicklooks can be viewed on the map in one of two ways:

- By clicking on the thumbnail in the search results pane.
- By using the map and holding the Ctrl key whilst clicking on one of the scenes displayed on the map.
