How to deal with missing coordinates

[sannegovaert]

If there are missing coordinates:

Should camtrapdp

• throw an error eg when rounding coordinates
• only warn and do the calculations or updates ignoring the na's

2 case studies so far

Case study 1

A Camtrap DP with missing coordinates in 1 deployment.
Calling round_coordinates() results in a non-specific error:

dataset <-
  dataset %>% 
  camtrapdp::round_coordinates(digits = 3)

> Error in if (digits >= original_digits) { :
> missing value where TRUE/FALSE needed

Case study 2

A Camtrap DP with missing coordinates in 1 deployment.
The DP is read and manipulated with camtrapdp. Eg some observations were filtered out. It is written to disk. Frictionless validation fails because the spatial metadata has been updated automatically and set to NA:
