rawturkey: Raw turkey dataset

In bacollier/moveud: moveud: Dynamic brownian bridge movement model individual time-step utilization distributions (R 3.2.5 Build)

Description

Raw turkey dataset

Format

The format is a dataframe

Try

Unique identifier for each GPS location attempt, NA's are allowed

FixDate

Date for each fix taken

FixTime

Time for each fix taken

Lat

Latitude

Lon

Longitude

Sats

Number of satellites used to calculate location

HDOP

Horizontal dilution of precision; measure of positional accuracy (lower is better)

Details

The raw turkey dataset is exactly what it says it is, a unformatted dataset which I have not turned into a move object, however, the code for manipulation a raw dataset such as this into a move object is included below. Additionally, the code below suggests that the user look at their data before creating the move object, as this is a nice example of having one outlier point that causes problems when estimating the utilization distribution.

Examples

data(rawturkey)
head(rawturkey)
plot(rawturkey$Lon, rawturkey$Lat)
rawturkey=rawturkey[rawturkey$Lon< -98.1,]
turkey=na.omit(rawturkey)
#rawturkey$DateTime=strptime(paste(rawturkey$FixDate, rawturkey$FixTime),"%m/%d/%Y %H:%M:%S") 
#Create object of class: move
#move.out <- move(x=turkey$Lon, y=turkey$Lat, time=as.POSIXct(turkey$DateTime, tz="GMT"), data=turkey, proj=CRS("+proj=longlat"), animal="3057")
#out <- spTransform(move.out, CRSobj="+proj=aeqd", center=TRUE)
#turkey <- brownian.bridge.dyn(object=out, location.error=15, margin=5, window.size=21, dimSize=85)
