1.RoadCrossings
• Question:Whattimeofdaydoanimalscrosstheroads?• Methods:– Downloadgoogleearthdatain1-weekintervalsstarting8/26/13foreachanimal.
– Stepthroughanimalsnightlytracksslowly– Identifycrossings,note‘localtimestamp’,estimatetimefcrossing
– Recorddatainexcelsheet• Results:– CreateGooglemapwithcolorcodeddotsshowinginterestingpatters(species/timeetc…)
– Makeagraphshowingyourresults
2,3,4,StartandEndofActivity• Question:whattimeofdaydotheanimalsstartandendtheiractivity
period?• Methods:
– DownloadACCViewer,besuretoupdateJava,runprogram.https://www.3dyne.com/movebank-acceleration-viewer/download/
– WithinProgram,Downloaddatafromtagid:– Login– Zoomin/out,notestart/endofactivityforeachnightofactivity(float

– Typeinsunset/sunrisetimesforeachdate(suggestonseparatelaptop)notedaylightsavingstime(+1hr)andgetfromhttp://aa.usno.navy.mil/data/docs/RS_OneYear.php
– Noteanyextensivedaytimeactivity• Results
– GraphStarttimeandsunsetovertime– Graphendtimeandsunriseovertime– Graphactivetimeperiodlengthovertime
5.EnergyExpenditureovertime• Question:howdoestheenergyexpenditure/activitylevelvaryovertime?• Methods
– DownloadACCViewer,besuretoupdateJava,runprogram.https://www.3dyne.com/movebank-acceleration-viewer/download/
– WithinProgram,Downloaddatafromtagid:– Login– Experimental/exportODBA,savefile,openinexcel– Makeday,hour,andday_hrcolumninexcel(cut_pasteexcelbluetext)
– UseexcelCrosstabstocalculateaveragevaluesperday,hour,andday_hr.cut/pastethesevaluesintoanewworksheet.
– Repeatforall3animals• Results
– Graphaveragedailyodbaovertime.– Graphaveragehourlyodbaovertime– Graphavergeday_hrodbaovertime– Bonus,plothourlyaveragesforeachdayasseparatelinesonthesamegraph
6.Distancemovedpernight• Question:Howfardidtheanimalsmovepernight.• Methods
– DownloaddatafromMovebankasexcel– Deleteallrowsmissinglocationdata– Sortbyanimal,then‘localtimestamp’– UseUTMcoordinates&Pythagorean'stheoremtocalculatethedistancemovedineachtimestep.
– Makeday,hour,andday_hrcolumninexcel(bluetextinodbaworksheet)
– UseexcelCrosstabstocalculateaveragevaluesperday,hour,andday_hr.cut/pastethesevaluesintoanewworksheet.
– Repeatforall3animals• Results
– Graphaveragedailymovementrateovertime.– Graphaveragehourlymovementrateovertime– Graphavergeday_hrmovementrateovertime
7.Interactionsbetweenanimals• Howoften,andwhere,doanimalsinteract• Methods
– Downloadfrom:http://web.engr.illinois.edu/~klei2/movemine/– Runthethefile:MiningToolsFx.jar– Login:– SelectNCSUCampusCarnivores,Downloadfromserver– SetGap(min)15,ThreshGap(hr)2– ClickMining/DistanceCalculation,saveimage(png)anddata(csv).Lookatdata
– Clickmining/significance.Keep100roundsofsimulation,try20,50,100,250m.Savetheonesyouthinkaremeaningful.
– Clickmining/plottrajectories.GetKMLfile.Tryeachpairofindividuals.Startwith25mand30min,thentryothervariations.
– OpenKML’sinGoogleEarth,saveinterestingmaps.• Results
– Distanceandsignificancematrices– Screen/shotstellingmainresultsofinteractionsites
8.DenSites• Question:wheredoanimalsspendtheday?• Methods– DownloaddatafromMovebankasexcelfile–Makeanewcolumnforhourusinglocaltime– LoaddataintoGISasshapefile–Makemapshowingresults– Summarizeresultsperanimal(#ofdens)andperdensite(#ofvisit)
• Results–Map(s)showingdens– Graphsshowingsummarystatistics
