Median Length: (No Longer an Option)The number of depths needed in a neighborhood in order to generate a CUBE estimate. (In the Projects distance units)Originally, you had to have a minimum number of depths (11) in a neighborhood in order to generate a CUBE estimate.Ĭapture Distance:The influence radius of a sounding is equal to the depth times the Capture Distance Scale percentage. Node GenerationRead ParametersNode Spacing:User Defined Distance between depth estimates. HYCUBE Read Parameters*HYPACK Multibeam Training Seminar* This will reduce the number of Hypotheses that CUBE will generate

Recommended that you Apply and Run some Filters in Phase 2 to minimize the amount of obvious fliers or spikes in the data Must be in HS2 format, so you must get to Phase 2 MBMAX

Note:CUBE hypotheses are not actual soundings, but are estimates of depth at each node, based upon the data points in the nodes neighborhood.Ĭube Grid and NeighborhoodsA series of CUBE nodes make a CUBE GRID.Soundings about the neighborhood of each node are used to generate depth estimates for the node (Hypotheses).If there are multiple depth hypotheses at a node, CUBE selects its best estimate of the depth.*HYPACK Multibeam Training Seminar*įirst Step*HYPACK Multibeam Training Seminar* Requires Minimal to No Pre-Editing Introduction the basics*HYPACK Multibeam Training Seminar*Z-ValuesUncertaintyRatio# of HypothesesHYSWEEPSURVEYHSXMBMAXHS2HYCUBEXYZĬUBE Terminolog圜UBE Node: An X-Y point where CUBE will make depth estimates based on the surrounding data points.CUBE Nodes are spaced at User Defined fixed distances, resulting in a square grid.*HYPACK Multibeam Training Seminar*ĬUBE Terminolog圜UBE Neighborhood: The area surrounding a CUBE Node where depths can influence the hypothesesHYPOTHESIS: A possible depth estimate at a node.A CUBE Node can have multiple hypotheses.
