Help with Python Script - Selecting by Location - Sql string

DeleteDelete

My goal with this script is to select points within a polygon based on a sql statement that identifies the polygon to base the extraction on. If anyone has any ideas, it would be greatly appreciated.

# Import arcpy module
import arcpy

# Local variables:
SQL_Expression = "SELECT * FROM Public_Seed_Grounds WHERE \"SEEDGRND\" = 'Lake Felicity'"
Public_Seed_Grounds_shp = "C:\\Path\\Public_Seed_Grounds.shp"
VMS_InsideSDG = "VMS_InsideSDG"
Lake_Felicity = "VMS_InsideSDG"
FelicityVMS_PointsforAnalysis100_shp = "C:\\Path\\FelicityVMS_PointsforAnalysis100.shp"
FelicityVMS_PointsforAnalysis100_Collect_shp = "C:\\Path\\FelicityVMS_PointsforAnalysis100_Collect.shp"
FelicityVMS_PointsforAnalysi_shp = "C:\\Path\\FelicityVMS_PointsforAnalysi.shp"
FelicityVMS_PointsforAnalysi_lyr = "C:\\Path\\FelicityVMS_PointsforAnalysi.lyr"

# Process: Select Layer By Location
arcpy.SelectLayerByLocation_management(VMS_InsideSDG, "INTERSECT", Public_Seed_Grounds_shp, "1 Miles", "NEW_SELECTION")

# Process: Copy Features
arcpy.CopyFeatures_management(Lake_Felicity, FelicityVMS_PointsforAnalysis100_shp, "", "0", "0", "0")

# Process: Integrate
arcpy.Integrate_management("C:\\Path\\FelicityVMS_PointsforAnalysis100.shp #", "100 Feet")

# Process: Collect Events
arcpy.CollectEvents_stats(FelicityVMS_PointsforAnalysis100_shp, FelicityVMS_PointsforAnalysis100_Collect_shp)

# Process: Hot Spot Analysis (Getis-Ord Gi*)
arcpy.HotSpots_stats(FelicityVMS_PointsforAnalysis100_Collect_shp, "ICOUNT", FelicityVMS_PointsforAnalysi_shp, "INVERSE_DISTANCE", "EUCLIDEAN_DISTANCE", "NONE", "", "", "")

# Process: ZScore Rendering
arcpy.ZRenderer_stats(FelicityVMS_PointsforAnalysi_shp, "GiZScore", FelicityVMS_PointsforAnalysi_lyr)

Add these lines before your select by location, change your select by location to the new feature layer.

Public_Seed_Grounds_lyr = "Public_Seed_Grounds_lyr" arcpy.MakeFeatureLayer_management(Public_Seed_Grounds_shp, Public_Seed_Grounds_lyr, "\"SEEDGRND\" = 'Lake Felicity'")  arcpy.SelectLayerByLocation_management(VMS_InsideSDG, "INTERSECT", Public_Seed_Grounds_lyr, "1 Miles", "NEW_SELECTION")

Solved the issue. Altered my model and now the python script works accordingly. Posting for anyone whomay find this script for hot spot analysis helpful.

import arcpy

# Local variables:
Public_Seed_Grounds = "C:\\PATH\\Public_Seed_Grounds.shp"
Raw_Data = "C:\\PATH\\GIS\\Analysis\\VMS\\RawData.shp"
VMS_Events_Hackberry__1_mile_Layer_ = "RawData_Layer"
VMS_Events_Hackberry__1_mile_Shape_ = "C:\\PATH\\GIS\\Analysis\\VMS\\Model\\Test\\VMS_Data_HackberryBay.shp"
VMS_Events_Hackberry__150__Aggregation_ = "C:\\PATH\\GIS\\Analysis\\VMS\\Model\\Test\\Aggregate\\VMS_Data_Hackberry150_Aggregate.shp"
Hackberry_HotSpots__150__ = "C:\\PATH\\GIS\\Analysis\\VMS\\HotSpotAnalysis\\Hackberry_Hotspot150.shp"
Hackberry_ZScore__150__ = "C:\\PATH\\GIS\\Analysis\\VMS\\HotSpotAnalysis\\Hackberry_Hotspot150.lyr"
Seed_Ground_Selection = "Hackberry_Bay_Selection"
Raw_Data_Layer = "RawData_Layer"

# Process: Make Feature Layer (2)

# Process: Select Layer By Location

# Process: Copy Features
arcpy.CopyFeatures_management(VMS_Events_Hackberry__1_mile_Layer_, VMS_Events_Hackberry__1_mile_Shape_, "", "0", "0", "0")

# Process: Integrate

# Process: Collect Events

# Process: ZScore Rendering
arcpy.ZRenderer_stats(Hackberry_HotSpots__150__, "GiZScore", Hackberry_ZScore__150__)

I really appreciate the help! This worked perfectly. However, I am having trouble applying this to the model I made. It seems like I am missing a variable (The layer/feature to query the points). I have attached the model along with the new string, If you have the time...

Thanks again!
