feature
Afeatureisaphysicalobjectoreventthathasalocationintherealworld,
whichyouwanttocollectpositionand/ordescriptiveinformation(attributes)
about.Featurescanbeclassifiedassurfaceornon‐surfacefeatures,and
againaspoints,lines/breaklines,orboundaries/areas.

GLONASS
GlobalOrbitingNavigationSatelliteSystem.GLONASSisaSovietspace‐based
navigationsystemcomparabletotheAmericanGPSsystem.Theoperational
systemconsistsof21operationaland3non‐operationalsatellitesin3orbit

HDOP
HorizontalDilutionofPrecision.HDOPisa
DOPvaluethatindicatesthe
accuracyofhorizontalmeasurements.OtherDOPvaluesincludeVDOP
(verticalDOP)and
PDOP(PositionDOP).
UsingamaximumHDOPisidealforsituationswhereverticalprecisionisnot
particularlyimportant,andyourpositionyieldwouldbedecreasedbythe
verticalcomponentofthePDOP(forexample,ifyouarecollectingdata
undercanopy).
IBSS
InternetBaseStationService.ThisTrimbleservicemakesthesetupofan
Internet‐capablereceiverassimpleaspossible.Thebasestationcanbe
connectedtotheInternet(cableorwirelessly).Toaccessthedistribution
server,theuserenterapasswordintothereceiver.Tousetheserver,the
user
musthaveaTrimbleConnectedCommunitysitelicense.
