Translation of the *.aml commands to ArcGIS-ArcView based Tools

1. Step by Step Process

grid

fill justng_cg3 ng_a_fill sink

&type new guinea filled

ArcGIS-ArcView

ng_a_fdr = flowdirection(ng_a_fill, dropgrid, force)

&type new guinea flow direction done

ArcGIS-ArcView

ng_a_fac = FLOWACCUMULATION(ng_a_fdr)

&type new guinea flow accumulation done

ArcGIS-ArcView

&type Streams done

ArcGIS-ArcView

&type StreamLink done

ArcGIS-ArcView

&type StreamOrder done

ArcGIS-ArcView

&type StreamOrderCoverage done

ArcGIS-ArcView

or

acc250 = ZONALMAX(link250, ng_a_fac)

ArcGIS-ArcView

out250 = con(acc250 == ng_a_fac, link250)

ArcGIS-ArcView

BUILDVAT out250………..(this command does not supported by ArcGIS-ArcView)

wshd250 = WATERSHED(ng_a_fdr, out250)

ArcGIS-ArcView

BUILDVAT wshd250………..(this command does not supported by ArcGIS-ArcView)

ws250p = gridpoly(wshd250)

&type 250 Watershed done

ArcGIS-ArcView

Notes:

For basic command such as dissolve, eliminate, select also available on ArcGIS-ArcView tools.
