Spatio-temporal Calculation with Sentinel DataΒΆ
In the previous step we create a spatio-temporal dataset in unit dB. Now, we will convert the dB units to linear unit
with t.raster.mapcalc
. To do this we launch the mapcalc GUI with:
$ t.rast.mapcalc
We choose the space time raster dataset that we created in the previous step Intensity. To convert the unit [dB] in [linear] we use the formula:
pow(10, (dB/10))
Now, we will click Run
:
If we now list all spatio-temporal dataset we see two entries: The one for Intensity
and the another one
Intensity_lin
that we created in with t.raster.mapcalc
:
We can also import the dataset into the display. Here is the dataset in unit [dB]:
And here is the dataset in unit [linear]:
