How might it be possible to thin the dataset so I am seeing 1 point every 5 metre spacing?</SPAN><BR /><SPAN>2. In addition, how might it be possible to maintain the shoalest depth within that 5 metre spacing? (ie. the point closest to the water surface that is most likely to be of concern to a navigating ship)</SPAN><BR /><BR /><SPAN>Regards.</SPAN></BODY></HTML> Mon, 11 Mar 2013 02:09:06 GMT https://community.esri.com/t5/arcgis-spatial-analyst-questions/point-thinning-decimating-bathymetric-dataset-with/m-p/461002#M6643 JustinOdell 2013-03-11T02:09:06Z Re: Point Thinning / Decimating Bathymetric Dataset, with shoal bias https://community.esri.com/t5/arcgis-spatial-analyst-questions/point-thinning-decimating-bathymetric-dataset-with/m-p/461003#M6644 <HTML><HEAD></HEAD><BODY><SPAN>Hello Hydronaut,</SPAN><BR /><BR /><SPAN>Esri's bathymetric extension "ArcGIS for Maritime: Bathymetry" ships with a list of bathymetric-specific GeoProcessing tools.
