A GeoPressureR path contains positions along a bird trajectory.

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

path should always be used in combination with staps, joined by the composite key (tag_id, stap_id).

Paths

Name	Definition	Type
`tag_id`*	Unique identifier of the tag. Foreign key to `tags.tag_id`. Constraints required: `true` Example: `18LX`	string
`type`*	One of: `tag`: Created 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: `most_likely`	string
`stap_id`*	Identifier of the stationary period. Together with `tag_id`, this forms a foreign key to `staps` (`tag_id`, `stap_id`). Constraints required: `true` Example: `3`	number
`lat`	Latitude of the stationary period. Constraints required: `false` minimum: `-90` maximum: `90` Example: `52.70442` Same as http://rs.tdwg.org/dwc/terms/decimalLatitude	number
`lon`	Longitude of the stationary period. Constraints required: `false` minimum: `-180` maximum: `180` Example: `23.84995` Same as http://rs.tdwg.org/dwc/terms/decimalLongitude	number
`j`	Unique identifier for each trajectory. Only useful for `paths.type='simulation'`. Integer from `1` to `nj` as defined in `GeoPressureR::graph_simulation()`. Constraints required: `false` minimum: `1` Example: `1`	integer
