interp_init | R Documentation |
List photos in input directory and creates an environment for storing data during interpolation iterative process. This is a mandatory prerequisite for interpolating positions.
interp_init(path = ".")
path |
(optional) path where input and output are located. This is not necessary if the working directory is already set to that location. |
Search for image files in input/photo
and stores them in a data.frame.
As the process is iterative (a succession of manual modifications in JOSM and interpolations in R), it is necessary to keep track of intermediate results. Therefore, a temporary environment (named .exif) is created.
Once interpolation is over, it is possible to delete that environment
with interp_cleanup
.
Nothing. Only .exif$base
is created.
interp_init()
