[GIS] Extract parcel layers from vector pdf

feature extractionpdfshapefilevector

So, I have an interesting problem… I have a PDF file which has over 100 pages and each of these pages is displaying a map in vector format.

By using some third party program I was able to find out that one of these layers is a parcel layer.

Now, what I am trying to do here is extract just this layer for every page in this PDF document and then stitch each of the parcel layer pages back together.

I am looking for some program or script which will automate some or all parts of this without screwing up the parcel line geometry. Additionally, I am assuming that I probable will need to manually align each of the extracted vector parcel pages which I guess is fine but what I think I need for this to work is some type of basemap background, I was thinking if one script can extract all the parcel vectors and then some other program can load all of them into some mapping program, me manually alligning each page and then finally being able to "join" the seperate pages into one large parcel vector map that the same (or yet another gis program) can append the correct lat/long data and turn it into a shapefile.

Uggghhh, so… Does anyone know of a solution for this?

You can use the Aide Pdf to DXF converter to convert the pdf maps to dxf while you can open in either AutoCAD or ArcGIS to edit.

[GIS] Arcpy Creating Multi-page Table/PDF with Reportlab/PyPDF2

I had a similar problem four years ago and worked through it as https://stackoverflow.com/questions/9271370/how-to-repeat-table-column-headings-over-page-breaks-in-pdf-output-from-reportla

The code that I came up with was as below but basically I let ReportLab take care of the page breaks and just threw a table of any length at it:

from reportlab.platypus import SimpleDocTemplate, Table, TableStyle, Paragraph, Frame, Spacer
from reportlab.lib import colors
from reportlab.lib.units import cm
from reportlab.lib.pagesizes import A3, A4, landscape, portrait
from reportlab.lib.styles import ParagraphStyle, getSampleStyleSheet
from reportlab.lib.enums import TA_LEFT, TA_RIGHT, TA_CENTER, TA_JUSTIFY
from reportlab.pdfgen import canvas

pdfReportPages = "C:\\Temp\\test.pdf"
doc = SimpleDocTemplate(pdfReportPages, pagesize=A4)

# container for the "Flowable" objects
elements = []
styles=getSampleStyleSheet()
styleN = styles["Normal"]

# Make heading for each column and start data list
column1Heading = "COLUMN ONE HEADING"
column2Heading = "COLUMN TWO HEADING"
# Assemble data for each column using simple loop to append it into data list
data = [[column1Heading,column2Heading]]
for i in range(1,100):
    data.append([str(i),str(i)])

tableThatSplitsOverPages = Table(data, [6 * cm, 6 * cm], repeatRows=1)
tableThatSplitsOverPages.hAlign = 'LEFT'
tblStyle = TableStyle([('TEXTCOLOR',(0,0),(-1,-1),colors.black),
                       ('VALIGN',(0,0),(-1,-1),'TOP'),
                       ('LINEBELOW',(0,0),(-1,-1),1,colors.black),
                       ('BOX',(0,0),(-1,-1),1,colors.black),
                       ('BOX',(0,0),(0,-1),1,colors.black)])
tblStyle.add('BACKGROUND',(0,0),(1,0),colors.lightblue)
tblStyle.add('BACKGROUND',(0,1),(-1,-1),colors.white)
tableThatSplitsOverPages.setStyle(tblStyle)
elements.append(tableThatSplitsOverPages)

doc.build(elements)

[GIS] Creating bookmarked PDF from Mapbook (Python) export script

The PyPDF2 module works as needed in this situation. The script no longer uses arcpy.mapping.PDFDocumentCreate. The combo-PDF is now created using the PyPDF2 module. In the below script, it begins with the output = PyPDF2.PdfFileMerger().

Because multiple users need to access the module across the office network, installing the module on my machine would not have worked. Instead, the PyPDF2 module was placed in a network folder, and sys.path.insert was added to the script with the location to the network path.

Here is the working script that bookmarks each page within the combo-PDF.

import sys
sys.path.insert(0, r"H:\NetworkShared_PythonModules") # insert a path to the folder containing the PyPDF2 module
import PyPDF2, os, arcpy

mxdPath = r"C:\temp\MyMapBook.mxd" 
tempMap = arcpy.mapping.MapDocument(mxdPath)
tempDDP = tempMap.dataDrivenPages


outDir      = r"C:\temp"   #PDF Folder where the individual pages and Combo will be created
comboPDF    = r"MultiPage_PDF.pdf"        #Name of Combo PDF
finalpdf_filename = os.path.join(outDir, comboPDF)
output = PyPDF2.PdfFileMerger()

for pgIndex in range(1, tempDDP.pageCount + 1):
      tempDDP.currentPageID = pgIndex
      figName = str(tempDDP.pageRow.sdsFeatureName)
      figNumber = str(tempDDP.pageRow.Fig_Num_2015FSP)
      pageName = "Appendix Page-" + figNumber + "_" + figName + ".pdf"
      individualPagePDF = os.path.join(outDir, pageName)
      bookMarkText = "Figure A-" + figNumber + " --- " + figName

      #do something to the page before exporting.  e.g. add inset map, add table etc.

      ###################################################################
      tempDDP.exportToPDF(individualPagePDF, "CURRENT") # export to signle page PDF
      IndividualPageInput = PyPDF2.PdfFileReader(open(individualPagePDF, 'rb'))
      output.append(IndividualPageInput, bookMarkText)
      print pageName + " added to final mapbook pdf"                    
      ###################################################################

      #undo whatever page modifications you just did before the export

outputStream = file(finalpdf_filename, "wb")
output.setPageLayout("/SinglePage")#open the pdf to single page layout
output.setPageMode("/UseOutlines")#open the pdf with the bookMarks pane open
################################
output.write(outputStream)
outputStream.close()
del outputStream, output

##### Delete Objects
del tempMap, tempDDP
