The InSAR displacement maps post-processed by the `pyrocko` module `kite` |
|
|
|
|
are usually `Quadtree` downsampled (Jonsson, 2002). Each data point has a |
|
|

latitude, longitude, Line-of-sight displacement value [m] as well as an |
|
|
|
|
orientation and elevation angle, which define the Line-of-Sight. The data |
|
|
|
|
are associated with a weight matrix, which is the inverse of a full |
|
|
|
|
variance-covariance matrix (Sudhaus \& Jonsson, 2009). In principle, these |
|
|
|
|
data sets could stem from pixel offset maps. See also the documentation of |

the `kite` module. |
