dcooley / gpx Goto Github PK

Check if gpx files generate multilinestrings?

should these bee another geometry column?

I might ignore them for first release?

When parsing multiple gpx files, they may not all have the same format and attributes? Therefore, need to handle different columns

TODO - sfheaders

• make dependency
• store all tracks in a matrix (or DataFrame) with an 'id' value, then call sfheaders::sf::sf_linestring()

TODO

• properties only added if a vector is not all NA
• NAs are actually NA, not ""
• why does it need library(sf) loaded? (otherwise it errors)

so it's part of the vectorised loop

need to keep track and complete n_empty

Given recent discussions* about modularising rspatial, should this output to sf structures, or something else?

• can't be bothered finding links / references

• datetime
• scale [0,1]
• from_zero (count)
• format argument for specifying input time format?

actually stems from here: SymbolixAU/geojsonsf#63
