Problem: When you enter COGO measurements to create a feature it will not snap to any other feature. This can happen when you enter lot lines in a subdivision when you 'connect the dots' .   The Solution: Disclaimer: this is R&D at this stage. If you are using true curves Arcade will densify them. So please don’t use on real data, this is not production-ready.” Use attribute rule calculation to update the end vertex of a line if it falls within a specified tolerance to a point feature class. You can see that: 1. The entered COGO dimensions are preserved 2. While the line fell short it updated the end vertex to the point.   How this is implemented? When creating a new line (Insert trigger event), the end vertex of the line is extracted and buffered with the specified tolerance. That buffer is then intersected with the points. The number of intersected points are counted - if there is exactly one point that intersects the buffer the geometry of the line ($feature) is updated. This attribute rule returns a geometry ('Polyline' method) that is calculated directly into the shape field. Here is the expression:       //The attribute rule searchs for a point within the given search tolerance // If one point is found the line end point 'snaps' to that point //SETTINGS var tolerance = 1; //Set your desired tolerance var toleranceUnit = 'meter'; //Set to 'feet' or 'meter' or other var PointsFS = FeatureSetbyName($datastore,'Points',['*'], true); //Set 'Points' to the fully qualified table name //Variables var LineFirstVertexGeometry = Geometry($feature).Paths[0][0]; //geometry of first vertex var LineEndVertexGeometry = Geometry($feature).Paths[0][1]; //geometry of end vertex var EndVertexPolygonBuffer = Buffer(LineEndVertexGeometry,tolerance,toleranceUnit); //buffer last vertex var IntersectedPointsFS = Intersects(PointsFS,EndVertexPolygonBuffer); //FS of intersected points var CountPointsInTolerance = Count(IntersectedPointsFS); //how many points are intersected with buffer? //if there is one point in the buffer AND the line is a 2 point line (not a curve or polyline) if ((CountPointsInTolerance ==1) && (Count(Geometry($feature).paths[0]) == 2)){ var TargetPointGeometry = Geometry(First(IntersectedPointsFS)); //find the geometry of target point var x1 = TEXT(LineFirstVertexGeometry.x); //start X coordinate var y1 = TEXT(LineFirstVertexGeometry.y); //start Y coordinate var x2 = TEXT(TargetPointGeometry.x); //target X coordinate var y2 = TEXT(TargetPointGeometry.y); //target Y coordinate var SR = Geometry($feature).spatialReference; //spatial reference of the line var polylineJSON = { //create a JSON representation of the updated line "hasZ":true, "paths":[[[x1,y1],[x2,y2]]], "spatialReference":SR }; return Polyline(polylineJSON); //return the Polyline to update the SHP field }         Attribute rule setting:   Please share thoughts and comments: 1. Do you find this useful? 2. Should it auto-snap to start/end vertices of other lines instead of the points? 3. Should we ship it with the parcel fabric 4. If you are using it, do you see undesired behavior?   You can download the project package and give it a try. If you deploy it with real data,  make sure to reduce the tolerance. It was set to one for testing/development purposes.     ... View more

The City of Mississauga recently completed a digital land parcel modernization project and transformed their parcel maintenance environment from a CAD based system to the ArcGIS Pro Parcel Fabric. This presentation covers how the collaborative approach between the City of Mississauga and Esri Canada’s Land Information Solutions team ensured a successful outcome, from data migration through to implementation support, and provides current metrics and lessons learned. Presenters: o Esri Canada: Dave Horwood, Heather Page o Mississauga: Rajni Gupta, Hung Giang, Keti Konstantinova, Susie Campagna Tasca   ... View more
