paths.csv

A GeoPressureR path constains the positions of a bird’s trajectory.

In GeoPressureR, there are 4 types of path : tag, most_likely, simulation and geopressureviz. See paths.type for more details.

path should always be used in combinaison with staps which can be JOIN by tag_id and stap_id.

Paths

Source: paths-table-schema.json

Name	Definition	Type
`tag_id`*	Unique identifier of the tag. Foreign key to `tags.tag_id`. Constraints required: `true` Example: `18LX`	string
`stap_id`*	Identifier of the stationary period. Foreign key to `staps.stap_id` Constraints required: `true` Example: `3`	number
`type`*	One of: `tag`: Create with `tag2path()` from a likelihood map. `most_likely`: Created with `graph_most_likely()` `simulation`: created by `graph_simulation()`: `geopressureviz`: created by `geopressureviz()`. Constraints required: `true` enum: `tag, most_likely, simulation, geopressureviz` Example: `3`	string
`lat`*	Latitude of the stationay period. Constraints required: `true` minimum: `-90` maximum: `90` Example: `52.70442` Same as http://rs.tdwg.org/dwc/terms/decimalLatitude	number
`lon`*	Longitude of the stationay period. Constraints required: `true` minimum: `-180` maximum: `180` Example: `23.84995` Same as http://rs.tdwg.org/dwc/terms/decimalLongitude	number
`ind`	Indices of the 2D coordinate of the spatial map defined in `GeoPressureR::tag_set_map()` (see also `GeoPressureR::map_expand()`. Useful to retrieve information on the graph (e.g. `GeoPressureR::path2edge()`. This value is the main way to create a path in GeoPressureR through `GeoPressureR::ind2path()`. Constraints required: `false` minimum: `1` Example: `23343`	integer
`j`	Only useful for `paths.type='simulation'`. Unique identifier for each trajectory, integer from `1` to `nj` as defined in `GeoPressureR::graph_simulation()``. Constraints required: `false` minimum: `1` Example: `1`	integer
`interp`	Only useful for `paths.type='tag'`. Boolean value to indicate if the position was interpolated as defined by the `interp` parameter in `GeoPressureR::tag2path()`. Constraints required: `false` Example: `true`	boolean
`known`	Boolean to indicate if the position is taken from a known value. Genearally, `TRUE` if `staps.known_lat` and `staps.known_lon` provided. Only different if `paths.type='tag'` and `use_known=FALSE` used in `GeoPressureR::tag2path()`. Constraints required: `false` Example: `true`	boolean
