Thanks a lot Jim.
the near tool will add fields to the layer used, am looking for another way which will return only the FIDs so i can loop through them and read information.
something like featurecursor interface in arcobjects.
thanks again for your replay.
Thanks Joshua ,
i tried the tool, it does not take a point object (it needs a feature layer as an input). i need to let the user input the point coordinates in order to search the nearest feature and return its information.
unfortunately the two methods (near_analysis, generate near table) are not helping.
You can use a point they created. It sounds like you need to code the ability for a person to enter a point first then run one of those two analysis options.
As is the case with most geoprocessing tools, the in_features can be ArcPy Geometry objects in addition to feature layers. In your case, create a PointGeometry object for the coordinates you want, and then pass that point geometry as the in_features to the Generate Near Table tool.
Thank you Joshua , Dan and JIM
Finally i created the tool which without your suggestions i couldn't make it.
def Closest_RD_XY( X, Y, Near_FC , Meters 😞
SR = arcpy.SpatialReference(4326)# WGS84 GCS
pntFC = arcpy.CreateFeatureclass_management("in_memory", "Acc_FC", "POINT", spatial_reference = SR)
# Just to check if layer created or not
if pntFC is None:
print "FeaClass 'Acc_FC' is not created"
In_curs = arcpy.da.InsertCursor( pntFC , ["SHAPE@XY"])
INValue = In_curs.insertRow([(X, Y)])
if INValue < 1 : print "point is not inserted"
# use the near tool in arcpy
arcpy.Near_analysis(pntFC, Near_FC , str(Meters)+ " Meters", "LOCATION","ANGLE","GEODESIC")
S_curs = arcpy.da.SearchCursor(pntFC, "*")
RD_ID = S_curs.next()
# return all information of the nearest feature
SN_curs =arcpy.da.SearchCursor(Near_FC, "*", "OBJECTID = " + str(RD_ID))
NFeature = SN_curs.next()
#delete in memory point layer
except Exception as e:
return "Error No Road found within 100 Meters 'Error ': " + e.message
