Address, buffer, select

jaykapalczynski

I am looking for the best way to eventually publish a GP tool that will accept an address, geocode the address, buffer the location X amount of distance and then select all the features it intersects. Resulting in a list of intersected features.

Any examples?

Well here is the final result.....and I will try and explain what is going on.....

Right now its set up to grab a few parameters that are going to be passed to it once it is published as a Rest Endpoint service....I have those 3 parameters hardcoded for testing purposes (address, distance, and unique ID)

# PARAMETERS PASSED FROM CALL TO THE SERVICE
searchAddress = "86 Rockland Street West Davenport, NY 13860"
searchDistance = 20
searchid = "123"<SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

The script takes the address and geocodes it to get XY

The XY are then used to create a temp Buffer at the user specified distance

this buffer is then used to select counties that INTERSECT it

this returned data is then packaged up to be send back to the requester...

Any questions please feel free to ask.....

THANK YOU ALL FOR YOUR HELP

OH one more thing....I was tripping up on the spatial reference....my Counties were in UTM and the XY being returned from the Geocode was Decimal Degrees....it could never find anything in the spatial select. Knowing that my data was in UTM I made sure that I set the output of the Geocode result to UTM as well

Last thing my data was also in meters so when the Miles were sent as parameters from the requester I had to convert those to meters to feed the buffer parameters

Here is an example on how to call the in memory buffer:

jaykapalczynski

This is what I have right now.....and it is working...ALTHOUGH I am using my own buffer FC....I still have not figure out how to use the in memory buffer:

arcpy.Buffer_analysis(ptGeometry, "IN_MEMORY/BufferGeom", "50 miles")

I am returning the correct number of results with my fake buffer FC so thats good....I just need to figure out how to implement the in memory buffer that I am trying to create.

I try and add the testBuffer instead of the direct call to my buffer FC....to this but it errors out....

testBuffer = arcpy.Buffer_analysis(ptGeometry, "IN_MEMORY/BufferGeom", "50 miles")

Successful in using FC buffer

finalResults = arcpy.SelectLayerByLocation_management('counties_lyr', 'INTERSECT', 'buffer_1')

Trying to Use IN memory buffer

finalResults = arcpy.SelectLayerByLocation_management('counties_lyr', 'INTERSECT', 'testBuffer')

You could create a point geometry from the XY coordinate, and then create an IN_MEMORY output for the buffer:

point <SPAN class="operator token">=</SPAN> arcpy<SPAN class="punctuation token">.</SPAN>Point<SPAN class="punctuation token">(</SPAN><SPAN class="number token">35.723</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="operator token">-</SPAN><SPAN class="number token">75.706</SPAN><SPAN class="punctuation token">)</SPAN>
ptGeometry <SPAN class="operator token">=</SPAN> arcpy<SPAN class="punctuation token">.</SPAN>PointGeometry<SPAN class="punctuation token">(</SPAN>point<SPAN class="punctuation token">)</SPAN>

arcpy<SPAN class="punctuation token">.</SPAN>Buffer_analysis<SPAN class="punctuation token">(</SPAN>ptGeometry<SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"IN_MEMORY/BufferGeom"</SPAN><SPAN class="punctuation token">,</SPAN> <SPAN class="string token">"100 Feet"</SPAN><SPAN class="punctuation token">)</SPAN><SPAN class="line-numbers-rows"><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN><SPAN>‍</SPAN></SPAN>

OK its really easy to Geocode an address I send to a python script...which yeilds an XY coordinate.

I am now looking at the Buffer analysis and it appears that I have to input a Feature Class.....Is there a way that I can pass it XY coordinates instead. I am not finding a reason to create a FC....

I want to Take an XY and create a Temp Buffer and select features from another FC without creating a Point Feature and a Buffer Feature.....Can I do this with temp features? Or do I have to create a point in a FC when its goecoded, then create a buffer FC from that point FC, then select the features from another FC and get a list of unique IDs.

Only to have to delete the point FC and Buffer FC everything I run the python script

jaykapalczynski

this is one cog in a larger wheel here and need to do this grammatically, which is why I am asking if I can call it, pass parameters, and get JSON back....this is the workflow that I need

jaykapalczynski

could I stand this up and then call it from .Net C#, passing it an address and buffer distance and get a JSON list back?

Hey Jay,

Take a look at the Public Notification widget:

Public Notification widget—Web AppBuilder for ArcGIS | Documentation

You have the option to write the result to a CSV.
