Definition query/Select Layer By Location

Tonyalmeida

I have over 2k parcels i need to create mail listings for. I have created a tool script that works great for individual listings or multiple parcels but i have to type each one in so that tool script won't work. . I have the list of parcels in a .dbf. how can use python to link all these parcels to a script, is that even possible?

Thanks.

ok, i like the idea of passing the excel list as an input parameter. How would i pass the list as a Parameter to the script?

import arcpy, string

# Allow processes to overwrite exisiting data
arcpy.OverwriteOutput = True

#Script arguments
TAX = arcpy.GetParameterAsText(0)
if TAX == '#' or not TAX:
    TAX = "C:/Temp/TaxParcels" # provide a default value if unspecified

values = arcpy.GetParameterAsText(1)
#if SELECT_BY == '#' or not SELECT_BY:
    #SELECT_BY = "\"PIN\" = 'PIN0392800000'" # provide a default value if unspecified

fieldName = "PIN"
values = values.split(";")  # split values into list
values = ["'{0}'".format(v) for v in values] # add single quotes
whereClause = "{0} IN ({1})".format(fieldName, ",".join(values))

Search_Distance = arcpy.GetParameterAsText(2)
if Search_Distance == '#' or not Search_Distance:
    Search_Distance = "300 Feet" # provide a default value if unspecified

Listing_xls = arcpy.GetParameterAsText(3)
if Listing_xls == '#' or not Listing_xls:
    Listing_xls = "C:\Temp\Listing.xls" # provide a default value if unspecified

# Local variables:
tax_Layer = "tax_Layer"
tax_Layer__2_ = "tax_Layer"
TaxParcels = "C:/Temp/TaxParcels" 
tax2_Layer = "tax2_Layer"
tax2_Layer__2_ = "tax2_Layer"

# Process: Make Feature Layer
arcpy.MakeFeatureLayer_management(TAX, tax_Layer)

# Process: Make Feature Layer (2)
arcpy.MakeFeatureLayer_management(TaxParcels, tax2_Layer)

# Process: Select Layer By Attribute
arcpy.SelectLayerByAttribute_management(tax2_Layer, "NEW_SELECTION", whereClause)

# Process: Select Layer By Location
arcpy.SelectLayerByLocation_management(tax_Layer, "WITHIN_A_DISTANCE", tax2_Layer__2_, Search_Distance, "NEW_SELECTION")

I am making an assumption that the 500 parcels are in some kind of a list. I think that you should be able to loop through your list (or a file containing the list) and call your tool. I haven't done any testing, but the idea would be something like:

import arcpy

# Load the toolbox and get the tool's parameters, using the tool
#  name ( ie. "myToolbox" - not the tool label "My Toolbox" )
arcpy.ImportToolbox(r"C:\Projects\MyToolbox.tbx", "myToolbox")

# read your list file

for item in listFile:

    arcpy.NameOfTool_myToolbox(item) # your tool's parameters<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

As an alternative, you might be able to adapt your script tool to use a list file as an input parameter instead of a manual entry. I suppose you could get a lot of duplicate parcels when you work your way through the list. If so, you could add a flag field to your parcel layer and select all parcels within your buffer distance of the flagged parcels.

This may be helpful as an example. It solves a problem that sounds a little like yours. It finds address for sending out notifications to property owners of upcoming tree trimming around power lines. It takes a sub network in a power distribution system identified by a feeder ID. Buffers it to 20 feet finds all of the parcels that the buffer hits. Then gets the owner address from a point feature class and a join. It also dumps out a bunch of feature classes to a FGDB for the mapping folks. So, they can quickly makeup maps for target ares.

You can see a select by location used in the select_append_by_buffer function....

have you geocoded the addresses? assuming you have them, then that would become your 'point' file

I need to notify all the owners within 600 ft of about 500 properties individually to 2k. I want to be able to some how make these listings with out having to type/sarch each of the those 500 individually.

The tool has a arcpy.GetParameterAsText(0), the script takes that number and selects layer by attributes then selects layer by location with the search distance, then exports the selected feature layers attributes to a .xls. I currently use this to do a simple listing but i am trying to avoid having to type all 500 in.

thanks.

Can you provide a little more description of the workflow of your project? Do you want to select a group of parcels by location and link them to a table of owner information? What do you type into your tool for individual and multiple listings?
