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))
Create a Mapset

Now, we will click Run:

Create a Mapset

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:

Create a Mapset

We can also import the dataset into the display. Here is the dataset in unit [dB]:

And here is the dataset in unit [linear]:
