Hello, so I have successfully created OLCI maps (Chlorophyll maps). Now I wanted to know if it is possible to
extract the value from a specific point or area. Can anyone provide any insight? I have never done it so unable to get clues from previous similar questions.
There are actually two ways to do it. One is for doing it on a single scene and one for doing it on a bunch of scenes.
You can add Pins . In the Pin Manager you can configure the displayed data and then you can export it to text file.
When using the PixEx Tool, there is a problem for me, maybe you or someone else can help me with.
I made temperature Images for the City of Cologne and now i want to extract Pixel Values from the Rhine River. So i made 7 Pins in the River in one Scene and opened the Pixel Manager. Here i configured the Pixel Data like you said, to see the °C Temperature Values for my Pins:
That’s strange. I have no idea.
For me it looks like the ones belong to the last column and the °C_neu has no value.
If you enable the display of control character like linefeed in your editor, you might see it.
I think the default notepad in Windows can’t do it.
I would suggest an editor like Notepad++ or pspad.
There you see 2 tabs. So, this column is skipped. This can happen if the data is not valid at this location. However, the images you have posted indicate valid data.
What happens if you remove the first product and let the extraction run only on the two other products?
