arcgis.geometry module

The arcgis.geometry module defines useful geometry types for working with geographic information and GIS functionality. It provides functions which use geometric types as input and output as well as functions for easily converting geometries between different representations.

Several functions accept geometries represented as dictionaries and the geometry objects in this module behave like them as well as support the ‘.’ (dot) notation providing attribute access.

..note::

It is recommended to have ArcPy or Shapely downloaded for most Geometry methods and property usage.

Examples:

# Example Point

>>> pt = Point({"x" : -118.15, "y" : 33.80, "spatialReference" : {"wkid" : 4326}})
>>> print (pt.is_valid)
True
>>> print (pt.type) # POINT
'POINT'
>>> print (pt)
'{"x" : -118.15, "y" : 33.80, "spatialReference" : {"wkid" : 4326}}'
>>> print (pt.x, pt.y)
(-118.15,33.80)

# Example Polyline

>>> line = {
  "paths" : [[[-97.06138,32.837],[-97.06133,32.836],[-97.06124,32.834],[-97.06127,32.832]],
             [[-97.06326,32.759],[-97.06298,32.755]]],
  "spatialReference" : {"wkid" : 4326}
}
>>> polyline = Polyline(line)
>>> print(polyline)
'{"paths" : [[[-97.06138,32.837],[-97.06133,32.836],[-97.06124,32.834],[-97.06127,32.832]],[[-97.06326,32.759],[-97.06298,32.755]]],"spatialReference" : {"wkid" : 4326}}'
>>> print(polyline.is_valid)
True

# Example INVALID Geometry

>>> line = {
  "paths" : [[[-97.06138],[-97.06133,32.836],[-97.06124,32.834],[-97.06127,32.832]],
             [[-97.06326,32.759],[-97.06298,32.755]]],
  "spatialReference" : {"wkid" : 4326}
}
>>> polyline = Polyline(line)
>>> print(polyline)
'''{"paths" : [[[-97.06138],[-97.06133,32.836],[-97.06124,32.834],[-97.06127,32.832]],

>>>print(polyline.is_valid)
False

The same patterna can be repeated for Polygon, MultiPoint and SpatialReference.

You can create a Geometry even when you don’t know the exact type. The Geometry constructor can find the geometry type and returns the correct type as the example below demonstrates:

# Example Unknown Geometry Type

>>> geom = Geometry({
  "rings" : [[[-97.06138,32.837],[-97.06133,32.836],[-97.06124,32.834],[-97.06127,32.832],
              [-97.06138,32.837]],[[-97.06326,32.759],[-97.06298,32.755],[-97.06153,32.749],
              [-97.06326,32.759]]],
  "spatialReference" : {"wkid" : 4326}
})
>>> print (geom.type) # Polygon
'Polygon'
>>> print(isinstance(geom, Polygon)
True

Point

class arcgis.geometry.Point(iterable=None, **kwargs)

The Point class contains x and y fields along with a SpatialReference field. A Point can also contain m and z fields. A Point is empty when its x field is present and has the value null or the string NaN. An empty point has no location in space.

coordinates()

Retrieves the coordinates of the Point as an np.array

#Usage Example

fill_color	An optional string. Hex string for fill color. Default is to use “#66cc99” if geometry is valid, and “#ff3333” if invalid.

Returns

An SVG circle element

property type

Gets the type of the current Point object.

MultiPoint

class arcgis.geometry.MultiPoint(iterable=None, **kwargs)

A multipoint contains an array of Point, along with a SpatialReference field. A multipoint can also have boolean-valued hasZ and hasM fields. These fields control the interpretation of elements of the points array.

Note

Omitting an hasZ or hasM field is equivalent to setting it to false.

Each element of the points array is itself an array of two, three, or four numbers. It will have two elements for 2D points, two or three elements for 2D points with Ms, three elements for 3D points, and three or four elements for 3D points with Ms. In all cases, the x coordinate is at index 0 of a point’s array, and the y coordinate is at index 1. For 2D points with Ms, the m coordinate, if present, is at index 2. For 3D points, the Z coordinate is required and is at index 2. For 3D points with Ms, the Z coordinate is at index 2, and the M coordinate, if present, is at index 3.

Note

An empty multipoint has a points field with no elements. Empty points are ignored.

coordinates()

Retrieves the coordinates of the MultiPoint as an np.array

#Usage Example

>>> coords = multiPoint.coordinates()
>>> coords
    [ [x1,y1,m1,z1], [x2,y2,m2,z2],...]

Returns

svg(scale_factor=1.0, fill_color=None)

Returns a group of SVG (Scalable Vector Graphic) circle element for the MultiPoint geometry.

Keys	Description
scale_factor	An optional float. Multiplication factor for the SVG circle diameter. Default is 1.
fill_color	An optional string. Hex string for fill color. Default is to use “#66cc99” if geometry is valid, and “#ff3333” if invalid.

Returns

A group of SVG circle elements

property type

Gets the type of the current MultiPoint object.

Polyline

class arcgis.geometry.Polyline(iterable=None, **kwargs)

The Polyline contains an array of paths or curvePaths and a SpatialReference. For Polylines with curvePaths, see the sections on JSON curve object and Polyline with curve. Each path is represented as an array of Point, and each point in the path is represented as an array of numbers. A Polyline can also have boolean-valued hasM and hasZ fields.

Note

See the description of MultiPoint for details on how the point arrays are interpreted.

An empty PolyLine is represented with an empty array for the paths field. Nulls and/or NaNs embedded in an otherwise defined coordinate stream for Polylines and Polygon objects is a syntax error.

coordinates()

Retrieves the coordinates of the Polyline as a np.array

#Usage Example

>>> coords = polyLine.coordinates()
>>> coords
    [ [x1,y1,m1,z1], [x2,y2,m2,z2],...]

Keys	Description
scale_factor	An optional float. Multiplication factor for the SVG stroke-width. Default is 1.
stroke_color	An optional string. Hex string for fill color. Default is to use “#66cc99” if geometry is valid, and “#ff3333” if invalid.

Returns

The SVG polyline element for the LineString Geometry

property type

Gets the type of the current Polyline object.

Polygon

class arcgis.geometry.Polygon(iterable=None, **kwargs)

The Polygon contains an array of rings or curveRings and a SpatialReference. For Polygons with curveRings, see the sections on JSON curve object and Polygon with curve. Each ring is represented as an array of Point. The first point of each ring is always the same as the last point. Each point in the ring is represented as an array of numbers. A Polygon can also have boolean-valued hasM and hasZ fields.

An empty Polygon is represented with an empty array for the rings field. Null and/or NaNs embedded in an otherwise defined coordinate stream for Polyline and Polygons is a syntax error. Polygons should be topologically simple. Exterior rings are oriented clockwise, while holes are oriented counter-clockwise. Rings can touch at a vertex or self-touch at a vertex, but there should be no other intersections. Polygons returned by services are topologically simple. When drawing a polygon, use the even-odd fill rule. The even-odd fill rule will guarantee that the polygon will draw correctly even if the ring orientation is not as described above.

coordinates()

Retrieves the coordinates of the Polygon as an np.array

#Usage Example

>>> coords = polygon.coordinates()
>>> coords
    [ [x1,y1,m1,z1], [x2,y2,m2,z2],...,[x1,y1,m1,z1] ]

SpatialReference

class arcgis.geometry.SpatialReference(iterable=None, **kwargs)

A SpatialReference object can be defined using a well-known ID (wkid) or well-known text (wkt). The default tolerance and resolution values for the associated coordinate system are used.

Note

The x, y and z tolerance values are 1 mm or the equivalent in the unit of the coordinate system. If the coordinate system uses feet, the tolerance is 0.00328083333 ft. The resolution values are 10x smaller or 1/10 the tolerance values. Thus, 0.0001 m or 0.0003280833333 ft. For geographic coordinate systems using degrees, the equivalent of a mm at the equator is used.

The well-known ID (WKID) for a given spatial reference can occasionally change. For example, the WGS 1984 Web Mercator (Auxiliary Sphere) projection was originally assigned WKID 102100, but was later changed to 3857. To ensure backward compatibility with older spatial data servers, the JSON wkid property will always be the value that was originally assigned to an SR when it was created. An additional property, latestWkid, identifies the current WKID value (as of a given software release) associated with the same spatial reference.

A SpatialReference object can optionally include a definition for a vertical coordinate system (VCS), which is used to interpret the z-values of a geometry. A VCS defines units of measure, the location of z = 0, and whether the positive vertical direction is up or down. When a vertical coordinate system is specified with a WKID, the same caveat as mentioned above applies.

Note

There are two VCS WKID properties: vcsWkid and latestVcsWkid. A VCS WKT can also be embedded in the string value of the wkt property. In other words, the WKT syntax can be used to define an SR with both horizontal and vertical components in one string. If either part of an SR is custom, the entire SR will be serialized with only the wkt property.

Note

Starting at 10.3, Image Service supports image coordinate systems.

property as_arcpy

The as_arcpy property retrieves the class as an arcpy SpatialReference object.

Returns

An arcpy SpatialReference object

svg(scale_factor=1, fill_color=None)

fill_color	An optional string. Hex string for fill color. Default is to use “#66cc99” if geometry is valid, and “#ff3333” if invalid.

Returns

The SVG element

property type

Gets the type of the current Point object.

Geometry

class arcgis.geometry.Geometry(iterable=None, **kwargs)

Keys	Description
polygons	The array of Polygon whose areas and lengths are to be computed.
length_unit	The length unit in which the perimeters of polygons will be calculated. If calculation_type is planar, then length_unit can be any esriUnits constant (string or integer). If calculationType is not planar, then length_unit must be a linear esriUnits constant, such as esriSRUnit_Meter`(i.e. `9001`|`LengthUnits.METER) or esriSRUnit_SurveyMile`(i.e. `9035`|`LengthUnits.SURVEYMILE). If length_unit is not specified, the units are derived from spatial_ref. If spatial_ref is not specified as well, the units are in meters. For a list of valid units, see esriSRUnitType Constants and esriSRUnit2Type Constants.
area_unit	The area unit in which areas of polygons will be calculated. If calculation_type is planar, then area_unit can be any esriAreaUnits constant (dict or enum). If calculation_type is not planar, then area_unit must be a esriAreaUnits constant such as AreaUnits.SQUAREMETERS (i.e. {“areaUnit”: “esriSquareMeters”}) or AreaUnits.SQUAREMILES (i.e. {“areaUnit”: “esriSquareMiles”}). If area_unit is not specified, the units are derived from spatial_ref. If spatial_ref is not specified, then the units are in square meters. For a list of valid units, see esriAreaUnits Constants. The list of valid esriAreaUnits constants include, esriSquareInches | esriSquareFeet | esriSquareYards | esriAcres | esriSquareMiles | esriSquareMillimeters | esriSquareCentimeters | esriSquareDecimeters | esriSquareMeters | esriAres | esriHectares | esriSquareKilometers.
calculation_type	The type defined for the area and length calculation of the input geometries. The type can be one of the following values: 1. planar - Planar measurements use 2D Euclidean distance to calculate area and length. This should only be used if the area or length needs to be calculated in the given SpatialReference. Otherwise, use preserveShape. 2. geodesic - Use this type if you want to calculate an area or length using only the vertices of the Polygon and define the lines between the points as geodesic segments independent of the actual shape of the Polygon. A geodesic segment is the shortest path between two points on an ellipsoid. 3. preserveShape - This type calculates the area or length of the geometry on the surface of the Earth ellipsoid. The shape of the geometry in its coordinate system is preserved.

This should only be used if the area or length needs to be calculated in the given SpatialReference. Otherwise, use preserveShape. 2. geodesic - Use this type if you want to calculate an area or length using only the vertices of the Polygon and define the lines between the points as geodesic segments independent of the actual shape of the Polygon.

Note

Tracing the geometry from its first vertex to the last will give you a direction along the geometry.

In these terms, it is simple to infer where the offset of even horizontal geometries will be constructed.

Keys	Description
geometries	An array of Point, MultiPoint, Polyline, or Polygon objects. The structure of each geometry in the array is the same as the structure of the JSON geometry objects returned by the ArcGIS REST API.
offset_distance	Specifies the distance for constructing an offset based on the input geometries. Note If the offset_distance parameter is positive, the constructed offset will be on the right side of the curve. Left-side offsets are constructed with negative values.
offset_unit	A unit for offset distance. If a unit is not specified, the units are derived from spatial_ref.
offset_how	The offset_how parameter determines how outer corners between segments are handled. The three options are as follows: esriGeometryOffsetRounded - Rounds the corner between extended offsets. esriGeometryOffsetBevelled - Squares off the corner after a given ratio distance. 3. esriGeometryOffsetMitered - Attempts to allow extended offsets to naturally intersect, but if that intersection occurs too far from the corner, the corner is eventually bevelled off at a fixed distance.
bevel_ratio	bevel_ratio is multiplied by the offset_distance, and the result determines how far a mitered offset intersection can be located before it is bevelled. When mitered is specified, bevel_ratio is ignored and 10 is used internally. When bevelled is specified, 1.1 will be used if bevel_ratio is not specified. bevel_ratio is ignored for rounded offset.
simplify_result	if simplify_result is set to true, then self intersecting loops will be removed from the result offset geometries. The default is false.
spatial_ref	A SpatialReference of the input geometries Well-Known ID or JSON object
future	An optional Boolean. This operation determines if the job is run asynchronously or not.

Note A transformation is needed only if the output SpatialReference contains a different geographic coordinate system than the input spatial reference.
transformforward	A Boolean value indicating whether or not to transform forward. The forward or reverse direction of transformation is implied in the name of the transformation. If transformation is specified, a value for the transform_Forward parameter must also be specified. The default value is false.
future	An optional Boolean. This operation determines if the job is run asynchronously or not.

reshape

arcgis.geometry.reshape(spatial_ref, target, reshaper, gis=None, future=False)

The reshape function is performed on a Geometry service resource. It reshapes a Polyline or Polygon feature by constructing a polyline over the feature. The feature takes the shape of the reshaper polyline from the first place the reshaper intersects the feature to the last.

Keys	Description
target	The Polyline or Polygon to be reshaped.
reshaper	The single-part Polyline that does the reshaping.
spatial_ref	A SpatialReference of the input geometries Well-Known ID or a JSON object for the input geometry
future	An optional Boolean. This operation determines if the job is run asynchronously or not.

Returns

A reshaped Polyline or Polygon object, or a GeometryJob object

to_geo_coordinate_string

arcgis.geometry.to_geo_coordinate_string(spatial_ref, coordinates, conversion_type, conversion_mode='mgrsDefault', num_of_digits=None, rounding=True, add_spaces=True, gis=None, future=False)

The to_geo_coordinate_string function is performed on a Geometry service resource. The function converts an array of xy-coordinates into well-known strings based on the conversion type and SpatialReference supplied by the User. Optional parameters are available for some conversion types. See from_geo_coordinate_strings for more information on the opposite conversion.

Note

If an optional parameter is not applicable for a particular conversion type, but a value is supplied for that parameter, the value will be ignored.

Keys	Description
spatial_ref	A SpatialReference of the input geometries Well-Known ID or JSON object
coordinates	An array of xy-coordinates in JSON format to be converted. Syntax: [[x1,y2],…[xN,yN]]
conversion-type	The conversion type of the input strings. Note Valid conversion types are: MGRS - Military Grid Reference System USNG - United States National Grid UTM - Universal Transverse Mercator GeoRef - World Geographic Reference System GARS - Global Area Reference System DMS - Degree Minute Second DDM - Degree Decimal Minute DD - Decimal Degree
conversion_mode	Conversion options for MGRS, UTM and GARS conversion types. Note Valid conversion modes for MGRS are: mgrsDefault - Default. Uses the spheroid from the given spatial reference. mgrsNewStyle - Treats all spheroids as new, like WGS 1984. The 80 degree longitude falls into Zone 60. mgrsOldStyle - Treats all spheroids as old, like Bessel 1841. The 180 degree longitude falls into Zone 60. mgrsNewWith180InZone01 - Same as mgrsNewStyle except the 180 degree longitude falls into Zone 01 mgrsOldWith180InZone01 - Same as mgrsOldStyle except the 180 degree longitude falls into Zone 01 Note Valid conversion modes for UTM are: utmDefault - Default. No options. utmNorthSouth - Uses north/south latitude indicators instead of zone numbers - Non-standard. Default is recommended
num_of_digits	The number of digits to output for each of the numerical portions in the string. The default value for num_of_digits varies depending on conversion_type.
rounding	If True, then numeric portions of the string are rounded to the nearest whole magnitude as specified by num_of_digits. Otherwise, numeric portions of the string are truncated. The rounding parameter applies only to conversion types MGRS, USNG and GeoRef. The default value is True.
addSpaces	If True, then spaces are added between components of the string. The addSpaces parameter applies only to conversion types MGRS, USNG and UTM. The default value for MGRS is False, while the default value for both USNG and UTM is True.
future	An optional Boolean. This operation determines if the job is run asynchronously or not.

>>> strings = from_geo_coordinate_string(spatial_ref = "wkid",
                                         coordinates = [[x1,y1], [x2,y2], [x3,y3]]
                                         conversion_type = "MGRS",
                                         conversion_mode = "mgrs_default",
                                         future = False)
>>> strings
    ["01N AA 66021 00000","11S NT 00000 62155", "31U BT 94071 65288"]

Returns

An array of Strings, or a GeometryJob object

trim_extend

arcgis.geometry.trim_extend(spatial_ref, polylines, trim_extend_to, extend_how=0, gis=None, future=False)

The trim_extend function is performed on a Geometry service resource. This function trims or extends each Polyline specified in the input array, using the user-specified guide polylines.

Note

When trimming features, the part to the left of the oriented cutting line is preserved in the output, and the other part is discarded. An empty Polyline is added to the output array if the corresponding input polyline is neither cut nor extended.

Keys	Description
polylines	An array of Polyline objects to trim or extend
trim_extend_to	A Polyline that is used as a guide for trimming or extending input polylines.
extend_how	A flag that is used along with the trimExtend function. 0 - By default, an extension considers both ends of a path. The old ends remain, and new points are added to the extended ends. The new points have attributes that are extrapolated from adjacent existing segments. 1 - If an extension is performed at an end, relocate the end point to the new position instead of leaving the old point and adding a new point at the new position. 2 - If an extension is performed at an end, do not extrapolate the end-segment’s attributes for the new point. Instead, make its attributes the same as the current end. Incompatible with esriNoAttributes. 4 - If an extension is performed at an end, do not extrapolate the end-segment’s attributes for the new point. Instead, make its attributes empty. Incompatible with esriKeepAttributes. 8 - Do not extend the ‘from’ end of any path. 16 - Do not extend the ‘to’ end of any path.
spatial_ref	A SpatialReference of the input geometries Well-Known ID or JSON object
future	An optional Boolean. This operation determines if the job is run asynchronously or not.

>>> polylines_arr = trim_extends(polylines = [polyline1,polyline2, ...],
                                 trim_extend_to = polyline_trimmer
                                 extend_how = 2,
                                 spatial_ref = "wkid",
                                 future = False)
>>> polyline_arr
    [polyline1, polyline2,...]

Returns

An array of Polyline objects, or a GeometryJob object

union

arcgis.geometry.union(geometries, spatial_ref=None, gis=None, future=False)

The union function is performed on a Geometry service resource. This function constructs the set-theoretic union of the geometries in the input array.

Note

All inputs must be of the same type.

Keys	Description
geometries	Required. An array of Point, MultiPoint, Polyline, or Polygon objects. The structure of each geometry in the array is the same as the structure of the JSON geometry objects returned by the ArcGIS REST API.
spatial_ref	An optional String or JSON Dict representing the wkid to be used. The default is the spatial reference found in the geometry or, if None found, then “4326”. Example: “4326” or {“wkid”:”4326”}
future	An optional Boolean. This operation determines if the job is run asynchronously or not.

Returns

The set-theoretic union of the Geometry objects, or a GeometryJob object
