METHODOLOGICAL INFORMATION
--------------------------


1. Description of methods used for collection/generation of data: 

Cranes were captured in Minnesota, USA, and fitted with GPS/GSM transmitters to monitor their movements. Full details of the methodology used to locate, capture, and tag birds is described in:
   Wolfson, D., Fieberg, J., Lawrence, J. S., Cooper, T. R., and Andersen, D. E. 2017. Range overlap between Mid-continent and Eastern sandhill cranes revealed by GPS-tracking. Wildlife Society Bulletin 41: 489-498.

Additional data collected from about these birds movement is available from:

DATA-SPECIFIC INFORMATION FOR: raw_april1_august31_2016.csv and raw_april1_august31_2017.csv
-----------------------------------------
The spreadsheets contain raw data returned by the Cellular Tracking Technologies devices. Missing data or faulty returns are usually represented as 'NA' but may also take the form of values outside of the expected range.    

Column descriptions below.
	a. id = unique ID number for each location in the csv file
	b. location-long = longitude (WGS84)
	c. location-lat = latitude (WGS84)
	d. gps:fix-type = fix quality (2=2D, 3=3D). Only 3D fixes have valid altitudes
	e. gps:hdop = GPS fix precision, horizontal dilution of precision
	f. ground-speed = ground speed in knots
	g. heading = course over ground (cardinal direction the animal is traveling at time of fix)
	h. height-above-msl = altitude (recorded in meters, relative to Mean Sea Level, EGM96)
	i. individual-local-identifier = alpha-numeric code given to each crane tagged with a GPS transmitter
	j. utm-easting = easting coordinate (NAD83 projection)
	k. utm-northing = northing coordinate (NAD83 projection)
	l. utm-zone = UTM zone of NAD83 projection
	m. study-timezone = local timezone of location
	n. study-local-timestamp = local date and time (format YYYY-MM-DD HH:MM:SS)
