converting contours to points

Kostas

Hello i have a mosaic dem and i have extracted contours wit interval = 2 meters. Now i want to convert contours to points xyz with distance of 1 meter from one point to another at the same contour line for each contour, any suggestion?

You can use some python to obtain the points you want:

import arcpy, os

fc_in = r"C:\Forum\Pasture\gdb\Contours.gdb\contours2"
fc_out = r"C:\Forum\Pasture\gdb\Contours.gdb\contour_pnts03"
fld_contour = "Contour"
interval = 1

# create empty output featureclass
sr = arcpy.Describe(fc_in).spatialReference
out_ws, out_name = os.path.split(fc_out)
arcpy.CreateFeatureclass_management(out_ws, out_name, "POINT", fc_in, "DISABLED", "DISABLED", sr)

# add field with contour value to output fc
arcpy.AddField_management(fc_out, fld_contour, "DOUBLE")

cnt = 0
with arcpy.da.InsertCursor(fc_out, ("SHAPE@", fld_contour)) as curs_out:
    with arcpy.da.SearchCursor(fc_in, ("SHAPE@", fld_contour)) as curs_in:
        for row_in in curs_in:
            polyline = row_in[0]
            contour = row_in[1]
            max_len = polyline.length
            d = 0
            while d < max_len:
                pnt = polyline.positionAlongLine(d, False)
                curs_out.insertRow((pnt.firstPoint, contour, ))
                cnt += 1
                if cnt % 100 == 0:
                    print "Processing point: {0}".format(cnt)
                # pnt.firstPoint
                d += interval
            curs_out.insertRow((polyline.lastPoint, contour, ))
            cnt += 1

Change the lines 3 and 4 to point to your input featureclass and the output you want to create.
