MapSeries—ArcGIS Pro | Documentation

Summary

The MapSeries object provides access to properties and methods for managing a spatial map series.

Discussion

An existing spatial map series can be referenced using the mapSeries property on a Layout object or using the createSpatialMapSeries method. You pass in a MapFrame object, an index_layer value, a name_field value, and other optional parameters to create the spatial map series.

Note:

Arcpy.mp supports two types of map series: spatial and bookmark. The mapSeries class represents spatial map series. The mapSeries property on the Layout object will return a MapSeries object if a spatial map series is present, a BookmarkMapSeries object, or a NoneType value if a map series is not present.

The MapSeries class can be used to access individual pages in a spatial map series for customization. For example, if a text element's string information needs to be formatted using custom logic, the spatial map series can be referenced and arcpy.mp can handle the custom text element string requirements as each page is being processed, as the script controls how to iterate through the pages. Another example is exporting a spatial map series to an output format other than PDF, such as PNG. See the second code sample below that demonstrates how to loop through each page in a spatial map series and export to a .png file.

The pages in a spatial map series can be exported to PDF using the exportToPDF method . When you export a spatial map series, all the dynamic elements associated with the spatial map series are supported. For example, dynamic text elements—such as page name, page number, attributes, and more—will automatically update. If map surrounds—such as legends, table frames, and chart frames—are set up to use the map series constraint, those elements will also dynamically update. The output PDF can be appended or inserted into other PDFs using the PDFDocument class. See the PDFDocument topic for more information and code samples.

The features that are displayed in a spatial map series can be further filtered using page queries where the values in the layer's specified field are matched against the current map series page name. The filter is only applied when a map series is enabled. The Layer class provides access to the pageQuery property and setPageQuery method.

The getDefinition and setDefinition methods provide access to CIM properties that are not exposed to the MapSeries object. For more information and code samples, see the Python CIM access help topic.

Properties

Property	Explanation	Data Type
clipToIndexFeature (Read and Write)	If set to True, Map clipLayers settings are applied to the current index feature. In order to modify or clear clipLayers on a map, clipToIndexFeature must be set to False.	Boolean
currentPageNumber (Read and Write)	Represents the active or current page for a layout that has map series enabled. Note: If the page number is set using a string defined field, currentPageNumber can be set to a string, for example, currentPageNumber = 'iv'.	Long
enabled (Read and Write)	Represents the enabled state of the map series. Tip: You should check to see if enabled is set to True before changing map series properties.	Boolean
indexLayer (Read Only)	Returns a reference to the index layer in a map series-enabled layout.	Layer
mapFrame (Read and Write)	A reference to the MapFrame that contains the index layer used to drive the map series. If you change the map frame, you might also need to reset the index layer and you should also call the refresh method	MapFrame
pageCount (Read Only)	Returns the total page count for a layout that has map series enabled. This corresponds to the number of features in the index layer.	Long
pageNameField (Read Only)	Returns a field object that represents the field used in the index feature class when setting up a map series.	Field

exportToPDF (out_pdf, {page_range_type}, {page_range_string}, {multiple_files}, {resolution}, {image_quality}, {compress_vector_graphics}, {image_compression}, {embed_fonts}, {layers_attributes}, {georef_info}, {jpeg_compression_quality}, {clip_to_elements}, {show_selection_symbology}, {output_as_image}, {embed_color_profile}, {pdf_accessibility}, {show_export_count}, {keep_layout_background}, {convert_markers}, {simulate_overprint})

Parameter	Explanation	Data Type
out_pdf	A string that represents the path and file name of the output export file.	String
page_range_type	The string value that designates how the pages will be printed. ALL—All pages are exported. CURRENT—The active or current page is exported. RANGE—Only pages listed in the page_range_string parameter are exported. SELECTED—Selected index layer features/pages are exported. (The default value is ALL)	String
page_range_string	A string that identifies the pages to be exported if the RANGE option in the page_range_type parameter is used (for example, 1, 3, 5-12). If any other page_range_type value is used, the page_range_string value will be ignored.	String
multiple_files	A string that controls how the output PDF file is created. By default, all pages are exported into a single, multipage document. The default is PDF_SINGLE_FILE. PDF_MULTIPLE_FILES_PAGE_NAME—Export each map series page to an individual file and append the page name to the file name. For example, Output.PDF will become Output_LakeErie.PDF PDF_MULTIPLE_FILES_PAGE_NUMBER—Export each map series page to an individual file and append the page number to the file name. For example, Output.PDF will become Output_1.PDF PDF_SINGLE_FILE—Export into a multipage, single file document. (The default value is PDF_SINGLE_FILE)	String
resolution	An integer that defines the resolution of the export file in dots per inch (dpi). (The default value is 96)	Integer
image_quality	A string that defines output image quality. BEST—An output image quality resample ratio of 1 BETTER—An output image quality resample ratio of 2 NORMAL—An output image quality resample ratio of 3 FASTER—An output image quality resample ratio of 4 FASTEST—An output image quality resample ratio of 5 (The default value is BEST)	String
compress_vector_graphics	A Boolean that controls the compression of vector and text portions of the output file. Image compression is defined separately. (The default value is True)	Boolean
image_compression	A string that defines the compression scheme used to compress image or raster data in the output file. ADAPTIVE—Automatically selects the best compression type for each image on the page. JPEG will be used for large images with many unique colors. DEFLATE will be used for all other images. JPEG—A lossy data compression. JPEG2000—Offers higher quality compression with smaller file size than JPEG. This compression is lossless if jpeg_compression_quality is set to 100. DEFLATE—A lossless data compression. LZW—Lempel-Ziv-Welch, a lossless data compression. NONE—Compression is not applied. RLE—Run-length encoded compression. (The default value is ADAPTIVE)	String
embed_fonts	A Boolean that controls the embedding of fonts in an export file. Font embedding allows text and character markers to be displayed correctly when the document is viewed on a computer that does not have the necessary fonts installed. (The default value is True)	Boolean
layers_attributes	A string that controls the inclusion of PDF layers and PDF object data (attributes) in the export file. LAYERS_ONLY—Export PDF layers only. LAYERS_AND_ATTRIBUTES—Export PDF layers and feature attributes. NONE—No setting is applied. (The default value is LAYERS_ONLY)	String
georef_info	A Boolean that enables the export of coordinate system information for each map frame into the output PDF file. (The default value is True)	Boolean
jpeg_compression_quality	A number that controls the compression quality value when image_compression is set to ADAPTIVE or JPEG. The valid range is 1 through 100. A jpeg_compression_quality of 100 provides the best quality images but creates large export files. The recommended range is 70 through 90. (The default value is 80)	Integer
clip_to_elements	If set to True, the layout is clipped to the smallest bounding box that includes all layout elements. (The default value is False)	Boolean
show_selection_symbology	A Boolean that controls whether the selection symbology should be displayed in the output. (The default value is False)	Boolean
output_as_image	If set to True, vector content can be saved as an image. Selecting this option for maps or layouts that contain vector layers with a high density of vertices can reduce the output file size. When exporting to PDF and this option is set to True, you cannot view PDF layers in the output. (The default value is False)	Boolean
embed_color_profile	If set to True, color profile information is embedded in the image's metadata. (The default value is True)	Boolean
pdf_accessibility	Output a tagged PDF file where text can be read by screen readers or other assistive technology. A tagged PDF file can include alt text—a text description of a graphic element that a screen reader uses to describe the element—for map frames, pictures, and chart frames. Alt text is added in the Element Pane for each element. (The default value is False)	Boolean
show_export_count	If set to True, you will see the status of each page being exported displayed in the Python shell. (The default value is False)	Boolean
keep_layout_background	If set to True, the white background will be included in the export. (The default value is True)	Boolean
convert_markers	A Boolean that controls the conversion of character-based marker symbols to polygons. This allows the symbols to appear correctly if the symbol font is not available or cannot be embedded. However, setting this parameter to True disables font embedding for all character-based marker symbols, which can result in a change in their appearance. (The default value is False)	Boolean
simulate_overprint	Sometimes called soft proofing, simulating overprinting shows a representation of how overlapping areas of ink will appear when printed on a page. You set up overprinting on symbol layers. (The default value is False)	Boolean

PDF files are designed to be consistently viewable and printable across various platforms. They are commonly used for distributing documents on the web and are a standard interchange format for content delivery. PDF files are editable in many graphics applications and retain annotation, labeling, and attribute data for map layers. PDF exports support embedding of fonts and can display symbology correctly even if the user does not have Esri fonts installed.

getDefinition (cim_version)

Parameter	Explanation	Data Type
cim_version	A string that represents the major version of the CIM that will be used. V2—The 2.x version of the CIM will be used. V3—The 3.x version of the CIM will be used.	String

Return Value

Data Type	Explanation
Object	Returns the CIM definition for a MapSeries.

For more information about working with the CIM and code samples, see Python CIM access.

getPageNumberFromName (page_name)

Parameter	Explanation	Data Type
page_name	A page number in the index layer that corresponds to the Name field that was used to set up the Map Series.	String

Many of the Map Series properties and methods use a page number value rather than the literal names of the pages used to create the index layer. The getPageNumberFromName method provides a mechanism to obtain a page number given a page name.

ms = layout.mapSeries
pageNumber = ms.getPageNumberFromName("HarborView")
ms.currentPageNumber = pageNumber

refresh ()

Use the refresh method if any of the following occurs:

Features are added to or deleted from your index layer.
Updates are made to the index field values.
The map frame extent is changed due to zooming, panning, or change to map scale.

The map series will retain the original settings in these cases until the refresh method is executed, or the project is saved and reopened.

setDefinition (definition_object)

Parameter	Explanation	Data Type
definition_object	A modified CIM definition object originally retrieved using getDefinition.	Object

For more information about working with the CIM and samples, see Python CIM Access.

Code sample

MapSeries example 1

The following script checks for the presence of a spatial map series and exports two individual pages to PDF base on the names of the pages.

import arcpy, os, sys
relpath = os.path.dirname(sys.argv[0])

p = arcpy.mp.ArcGISProject(os.path.join(relpath, 'GreatLakes', 'GreatLakes.aprx'))
lyt = p.listLayouts('Layout_MS')[0]
sms = lyt.mapSeries
if isinstance(sms, arcpy._mp.MapSeries):
  if sms.enabled:
    sms.currentPageNumber = sms.getPageNumberFromName("Lake Superior") 
    sms.exportToPDF(os.path.join(relpath, 'Output', 'Ex1_LakeSuperior.pdf'),
                                'CURRENT', resolution=300)
    sms.currentPageNumber = sms.getPageNumberFromName("Lake Huron") 
    sms.exportToPDF(os.path.join(relpath, 'Output', 'Ex1_LakeHuron.pdf'),
                                'CURRENT', resolution=300)
print("Finished")

MapSeries example 2

The following script exports each page of a spatial map series to individual .png files and uses the page name of the index feature as part of the output file name.

import arcpy, os, sys
relpath = os.path.dirname(sys.argv[0])

p = arcpy.mp.ArcGISProject(os.path.join(relpath, 'GreatLakes', 'GreatLakes.aprx'))
lyt = p.listLayouts('Layout_MS')[0]
sms = lyt.mapSeries
if ((type(sms).__name__ == 'MapSeries')):
  sms = lyt.mapSeries
  if sms.enabled:
    for pageNum in range(1, sms.pageCount + 1):  #All pages, zero based index
      sms.currentPageNumber = pageNum
      pageName = sms.pageRow.NAME   #NAME = field name in index layer
      print("Exporting {0}".format(pageName))  
      lyt.exportToPNG(os.path.join(relpath,'Output', f'Ex2_{pageName}.png'))
print("Finished")

MapSeries example 3

The following script selects index features, exports the selected pages to one multipage PDF, and clears the selection when complete.

import arcpy, os, sys
relpath = os.path.dirname(sys.argv[0])

p = arcpy.mp.ArcGISProject(os.path.join(relpath, 'GreatLakes', 'GreatLakes.aprx'))
lyt = p.listLayouts('Layout_MS')[0]
sms = lyt.mapSeries
if isinstance(sms, arcpy._mp.MapSeries): 
  if sms.enabled:
    indexLyr = sms.indexLayer
    arcpy.SelectLayerByAttribute_management(indexLyr, 'NEW_SELECTION',
                                            'AREA > 10000')
    sms.exportToPDF(os.path.join(relpath, 'Output',
                                'Ex3_QueriedLakes.pdf'), 'SELECTED')
    arcpy.SelectLayerByAttribute_management(indexLyr, 'CLEAR_SELECTION')
print('Finished')

MapSeries example 4

The following script creates a Map object, a Layout object, and a MapFrame object. Next, it creates a spatial map series and enables map clipping by setting clipMapToIndexFeature to True. It uses Python CIM access to modify some CIM properties that are not exposed to the MapSeries object. Examples are setting the starting page number, scale rounding, and clipping the data to the map index feature. Finally, it exports the map series to a single PDF.

import arcpy, os, sys
relpath = os.path.dirname(sys.argv[0])

#Function used to create a rectangle where the anchor point is lower left corner
def MakeRec_LL(llx, lly, w, h):
    xyRecList = [[llx, lly], [llx, lly+h], [llx+w,lly+h], [llx+w,lly], [llx,lly]]
    array = arcpy.Array([arcpy.Point(*coords) for coords in xyRecList])
    rec = arcpy.Polygon(array)
    return rec

p = arcpy.mp.ArcGISProject(os.path.join(relpath, 'GreatLakes', 'GreatLakes.aprx'))

#Create a new map and add index layer
m = p.createMap('New Map', 'MAP')
lyrFile = arcpy.mp.LayerFile(os.path.join(relpath, 'GreatLakes', 'GreatLakes.lyrx'))
lyr = m.addLayer(lyrFile)[0]

#Create a layout and map frame
lyt = p.createLayout(8.5, 11, 'INCH')
mf = lyt.createMapFrame(MakeRec_LL(0.5,5.5,7.5,5), m, "New Map Frame")

#Create and export a spatial map series
sms = lyt.createSpatialMapSeries(mf, lyr, 'NAME')
sms.clipToIndexFeature = true

#Modify CIM properties
sms_cim = sms.getDefinition('V3')
sms_cim.startingPageNumber = 2
sms.scaleRounding = 10000
sms.setDefinition(sms_cim)

#Export to PDF
sms.exportToPDF(os.path.join(relpath, 'Output', 'Ex4_NewSMS.pdf'))

MapSeries example 5

The following script exports all the pages from a spatial map series to a single PDF, exports all pages from a bookmark map series to another PDF, and combines the two resulting PDFs into a single, newly created PDF.

import arcpy, os, sys
relpath = os.path.dirname(sys.argv[0])
arcpy.env.overwriteOutput = True

p = arcpy.mp.ArcGISProject(os.path.join(relpath, 'GreatLakes', 'GreatLakes.aprx'))
#Export spatial map series
sms_lyt = p.listLayouts('Layout_MS')[0]                                  
sms = sms_lyt.mapSeries
if ((type(sms).__name__ == 'MapSeries')):
  if sms.enabled:
      print(os.path.join(relpath, 'Output', 'Temp_sms.pdf'))
      sms.exportToPDF(os.path.join(relpath, 'Output', 'Temp_sms.pdf'))

#Export bookmark map series
bms_lyt = p.listLayouts('Layout_BMS')[0]
bms = bms_lyt.mapSeries
if ((type(bms).__name__ == 'BookmarkMapSeries')): 
  if bms.enabled:
    bms.exportToPDF(os.path.join(relpath, 'Output', 'Temp_bms.pdf'))

#Combine PDFs and remove temporary files
comboPDF = arcpy.mp.PDFDocumentCreate(os.path.join(relpath, 'Output',
                                                   'Ex4_Combo.pdf'))
comboPDF.appendPages(os.path.join(relpath, 'Output', 'Temp_sms.pdf'))
os.remove(os.path.join(relpath, 'Output', 'Temp_sms.pdf'))
comboPDF.appendPages(os.path.join(relpath, 'Output', 'Temp_bms.pdf'))
os.remove(os.path.join(relpath, 'Output', 'Temp_bms.pdf'))
comboPDF.saveAndClose()
os.startfile(os.path.join(relpath, 'Output','Ex4_Combo.pdf'))
print('Finished')
