Mengekspor tabel ke file XYZ ASCII via ArcPy?

Saya mencari cara untuk mengekspor tabel ArcGIS (dibuat dengan alat Sampel ) ke file teks melalui ArcPy.

Saya dapat melakukan ini di ArcGIS melalui menu konteks dengan mengklik kanan tabel, tetapi belum menemukan cara untuk skrip ini.

Anda dapat melakukan ini menggunakan kursor untuk mengambil data dari tabel Anda dan menulis ke file teks yang dibatasi koma.

EDIT: Saya menambahkan blok kode yang lebih ringkas untuk menyelesaikan tugas menggunakan csvmodul Python

Jawaban Baru menggunakan kursor arcpy.da:

import arcpy,csv

table =r'c:\path\to\table'
outfile = r'c:\path\to\output\ascii\text\file'

#--first lets make a list of all of the fields in the table
fields = arcpy.ListFields(table)
field_names = [field.name for field in fields]

with open(outfile,'wb') as f:
    dw = csv.DictWriter(f,field_names)
    #--write all field names to the output file
    dw.writeheader()

    #--now we make the search cursor that will iterate through the rows of the table
    with arcpy.da.SearchCursor(table,field_names) as cursor:
        for row in cursor:
            dw.writerow(dict(zip(field_names,row)))

Jawaban Baru menggunakan kursor gaya lama:

import arcpy,csv

table =r'c:\path\to\table'
outfile = r'c:\path\to\output\ascii\text\file'      

#--first lets make a list of all of the fields in the table
fields = arcpy.ListFields(table)
field_names = [field.name for field in fields]

with open(outfile,'wb') as f:
    w = csv.writer(f)
    #--write all field names to the output file
    w.writerow(field_names)

    #--now we make the search cursor that will iterate through the rows of the table
    for row in arcpy.SearchCursor(table):
        field_vals = [row.getValue(field.name) for field in fields]
        w.writerow(field_vals)
    del row

#--first lets make a list of all of the fields in the table
fields = arcpy.ListFields(table)

i = 1

for field in fields:

    if i < len(fields):
        f.write('%s,' % field.name)
        i += 1
    else:
        f.write('%s\n' % field.name)

#--now we make the search cursor that will iterate through the rows of the table
rows = arcpy.SearchCursor(table)
for row in rows:
    i = 1
    for field in fields:
        if i < len(fields):
            f.write('%s,' % row.getValue(field.name))
            i += 1
        else:
            f.write('%s\n' % row.getValue(field.name))
del rows
f.close()

import arcpy

feature = "path to feature here"
# fieldnames must be explicitly provided. Note that you will get additional fields based on the feature type (e.g., "XCoord" and "YCoord" for point features)
fieldnames = [X.name for X in arcpy.ListFields(feature)]
# delimiter options "SPACE", "COMMA", or "SEMI-COLON"
# header options "ADD_FIELD_NAMES" or "NO_FIELD_NAMES"
arcpy.ExportXYv_stats(feature, fieldnames, "SPACE", "path to outfile", "ADD_FIELD_NAMES")

Ini adalah sepotong kode yang saya gunakan. Ini membantu saya menghasilkan semua file output saya ke file .txt dengan kisaran dari 0,100. Semoga bermanfaat

for x in xrange(0,100):
    if os.path.isfile(outfolder + "/" + "outputs" + str(x) +".shp" ):
       inFeatures = "selected_features" + str(x) +".shp"
       export_ASCII = "ASCII " + str(x) +".txt"
       arcpy.ExportXYv_stats(inFeatures, ["Cur1_pr2","Cur3_pl1","slp1"],"SPACE", export_ASCII,"ADD_FIELD_NAMES")
