The Spatial Info tool extracts tabular information about the spatial object. Attributes such as: area, spatial object, number of parts, number of points, and centroid Latitude /Longitude coordinates can be revealed.
Configuration Properties:
Select the spatial object from drop down list that to append spatial information to.
Select the information to append to the table by checking the appropriate box. Choices include:
Area (Square Kilometers) appends the calculated area in square kilometers of the spatial objects in the table.
Area (Square Miles) appends the calculated area in square miles of the spatial objects in the table.
Bounding Rectangle as Points appends the spatial objects (2 points) of the record to its bounding rectangle, based on the geographic extent of the incoming spatial object.
Bounding Rectangle as Polygon appends a spatial object (1 polygon) of the record to its bounding rectangle, based on the geographic extent of the incoming spatial object.
Bounding Rectangle as X and Y Fields appends four fields (BR_Left, BR_Top, BR_Right, BR_Bottom), directly related to the bounding rectangle extents' geographic coordinates.
Centroid as Spatial Object appends the spatial object of the record to the centroid.
Centroid as X and Y Fields appends two fields (X, Y) depicting the geographic coordinates of the center of its object.
End Points as Spatial Object appends the end point (extent or where the object sequence ends) of the records' spatial object.
End Points as X and Y Fields appends two fields (X, Y) depicting the geographic coordinates of the end point of a record's object.
Length (Kilometers) appends the line length, in kilometers, of the record's object. If the object is a line, this field will reflect the total line length. If the object is a polygon, this field will reflect the perimeter of the polygon object.
Length (Miles) appends the line length, in miles, of the record's object. If the object is a line, this field will reflect the total line length. If the object is a polygon, this field will reflect the perimeter of the polygon object.
Number of Partsappends the number of parts that make up the object (polylines and polygons only).
Number of Points appends the number of points that make up the object (polylines and polygons only).
Peano Key is used to merge the x-coordinate and y-coordinate of a point so the value can be stored in a one-dimensional array. To produce a Peano key the binary bits of the latitude and longitude value for each point are merged by alternating the bits to produce a new binary number.
Spatial Object Type appends the type of spatial object is associated with the file (Point, Line, Polyline, Polygon).
The difference between a polyline and a polygon is that a polyline contains multiple line segments, where a line has one start and one end point, but can have any number of points in between. A polyline can be quite complex as in the case of road systems, or rivers.
Specify the Projection for XY Output (Optional). By default Alteryx reports spatial information in WGS 84 projection. User can select a different known projection and return spatial information in that projection. Click to display the Edit Projection box.
