draw images of gps data points
The package visualizes gps data points as an image.
On full scale, each data point is drawn as a pixel.
Depending on how many points lie on a pixel, it may
be drawn in a brighter color.
This is controlled by Contrast and the color Palette.
A blur factor takes neighbour points into account
resulting in a smearing effect. On the downside
it slows down the compuation.
The package is a fairly simple implementation which is not optimized for speed. It is currently good enough for a some millions of points.
This is only the package. There are two interactive frontends:
- gui (windows only, based on lxn/walk)
- shiny (based on golang.org/x/exp/shiny)
