Navigating the EO59 website
Data page
On our Data page, you can find a list of your sites with the project name, the satellite used for monitoring, the information on when your site was last updated, a button to make an API key as well as download buttons for you to download the data for your site. You can also view the data online by clicking on “View data on map”
To download the data for your site, click the A button for the Ascending orbit or the D button for Descending orbit data in CSV or GeoJSON format.
To download the data for your site, click the A button for the Ascending orbit or the D button for Descending orbit data in CSV or GeoJSON format.
To download the data from the Corner Reflectors on your site, click the cA button for the Ascending data, or cD for the Descending data in CSV or GeoJSON format.
Your browser may ask for permission prior to downloading the data on your device.
Some sites have data from two different satellites - Sentinel-1 and COSMO-Skymed. In this case, data from Sentinel-1 is indicated as SA or SD, while data from COSMO-Skymed is shown as CA or CD.
Please note the differences between the notations for the Corner Reflectors (cA, cD) and COSMO-Skymed data (CA, CD)
If you do not see the Descending orbit or Corner Reflectors download button, it may mean that these datasets are not available for your site.
Map
You can switch themes of the map between Light Mode (LM) and Dark Mode (DM) in the upper right corner.
If you open your project on our online 3D map, and it has height "spikes" or the screen is black, this means the map did not load completely.
Fix this by clicking the Force Page Reload button in the upper right corner of the page, or refresh your tab.
It might take a moment for all the deformation points to load on the screen.
You can view the map in full-screen mode by clicking the four-headed arrow in the lower right corner of the map.
Zoom in and out of the map by clicking the plus and minus buttons in the lower right corner of the map, or by scrolling with your mouse. Click down on your mouse and drag to move around.
To change the direction of the 3D map, hold down the Control (ctrl) button on your keyboard as you click on the map and drag around.
The compass button underneath the zoom buttons can be clicked for Map reset bearing to north.
The home button on the upper left corner will reset the map into its default state.
The map scale can be found on the lower left corner.
The deformation legend shows the color scale based on change in millimeters per year.
To switch between the Ascending and the Descending orbit or Corner Reflector layers, use the SA/SD or SAc/SDc buttons on the left side of the map.
If your site has data from two different satellites (see: Data page) use the buttons SA or SD for Sentinel-1 data and CA or CD for COSMO-Skymed data.
If the button is white, the layer is turned on. If it is gray, the layer has been turned off.
Using the filter button, you can filter out the displayed measurement points by their velocity and cumulative displacement. It will turn yellow once turned on.
Choose whether you want to exclude or include the points with your selected requirements (INC / EXC)
You can look at the deformation chart of a single point of interest by clicking on it.
By default, the Hover Query Mode button is turned on (colored yellow), which allows you to see the data of the measurement points by hovering over them. You can toggle this function on-off by clicking on the button with a circled question mark.
Using the polygon button feature you can select multiple points by creating a polygon around the desired points. Activate the polygon button in the top right of your screen (square shape with dots in the corners) and create a polygon on the map by clicking around the desired points. End the selection by clicking on the first point you started the shape with.
You can observe the points' displacement separately, as well as see their averaged cumulative deformation.
The selections can be cleared with the bin button.
An area can be "locked" by clicking anywhere else on the map. The area's borders will turn blue and it cannot be cleared with the bin button. To make it active again, just click on the shape again.
"Locked" area
Your selected points will each have their own colour on the map and the graph. This way you know which deformation line represents its corresponding point.
You can also turn some points on and off on the graph by clicking on them in the legend. Turned off points will be struckthrough.
If you’ve selected more than 10 points, you can only view their averaged deformation.
Deformation chart
The y axis on the deformation chart shows deformation in millimeters (mm) over time.
The x axis shows the time of the deformation.
Selecting data on a single orbit:
You can observe the deformation of individual points as well as their averaged deformation, when you select up to 10 points in single orbit
Selecting data on both orbits:
The chart will tell you how many points are selected in which orbit and will give you the color legend for them.
Selecting data with Corner Reflectors:
The chart will show you the whole timeline of the points selected. The Corner Reflector data will start from when it was seen by the satellite after its installation. Each line is represented with a different color and the legend can be seen right above the chart.
You can also hover your mouse over a certain point and get more detailed information, such as the deformation of that specific point on that date.
This feature can be switched on and off with a button next to the date box. If it has been turned off, the box with additional information will not appear on the graph when you hover over points.
Some projects have arrows in the deformation chart which show the directions of the movement of one point.
The black arrow shows the azimuth of the satellite's line of sight (LOS).
The colorful arrow shows the incidence angle of the line of sight (LOS)
Selecting a timeframe:
If you want to view data within a specific timeframe, you can select it with the calendar feature on the right corner of the deformation chart.
A calendar will open, with today's date highlighted. You can change the month and year by clicking on them.
First click on the starting date you would like to choose, then select the end date. The selected dates will be shown in blue.
Once you've clicked on the end date, the calendar will close automatically. The timeframe is displayed in yyyy/mm/dd format.
Timeframe can also be selected with the slider at the bottom of the deformation chart. Each line represents one month. Click the circle and drag it to the desired spot.
Keep in mind that when you have selected a timeframe, it will automatically be applied to any other point selections that you make afterwards, even when you have closed the chart.
You can change the timeframe by clicking on the displayed dates. To get the chart back into its original state and see the full time range, you can clear the current selection with the Reset Time Filter button on the left of the field or by deleting the dates and pressing the ENTER button on your keyboard.
Interpreting the data
Corner reflectors are represented by the white T-shapes and either cA or cD on the legend.
On a single orbit site (Ascending or Descending only), the deformation points are represented by dots.
On a site that has both orbits, Ascending and Descending, the deformation points are displayed with arrows, which represent the direction the satellite is looking.
The color of the dots or arrows represent the direction of the deformation, and is explained by the legend, where red stands for motion away from the satellite, blue represents motion toward it and green means the area is averaging no motion trend in either direction. Green does not indicate a lack of motion, season variability and elastic events are visible in the time series.
Be cautious when interpreting motion directions using the arrows. They are most helpful when you keep in mind, they are indicating the direction the satellite is looking, not the necessarily the direction of motion. When the arrow is red, this indicates that the motion average along the time series is away from the satellite in the direction of the arrow. When the arrow is blue, this indicates that the motion average along the time series is towards the satellite. This means that the motion is trending in the opposite direction than the arrow is pointing.
