Python Map Automation Beyond the Basics of arcpy.mapping

Transcription

1 2013 Esri International User Conference July 8 12, 2013 San Diego, California Technical Workshop Python Map Automation Beyond the Basics of arcpy.mapping Jeff Barrette Jeff Moulds Esri UC2013. Technical Workshop.

2 Basic rules Reference an MXD using a path or current keyword - When using CURRENT - Always run in foreground - May need to refresh (e.g., RefreshActiveView) Uniquely name all the objects you want to reference Pre-author MXDs with all possible elements - Can t create new objects (e.g., north arrow, data frames) - Author the extra elements off the page - No "New Map" function, so keep an empty MXD available This is not a replacement for ArcObjects we are trying to draw a line in the sand Us You The Line

3 Sample Application Jeff Barrette Esri UC2013. Technical Workshop.

4 What s new topic What s new Mapping What s new for automating map workflows

5 Cloning elements You can now clone text and graphic elements This allows you to automate things like dynamic tables Example: vertl = arcpy.mapping.listlayoutelements( mxd, GRAPHIC_ELEMENT, VerticalLine )[0] vertl.elementpositionx = xpos; vertl.elementpositiony = 4 vert1.elementheight = 3 for line in range(1, numcolumns+1): vert_clone = vertline.clone("_clone") xpos = xpos + colwidth vert_clone.elementpositionx = xpos

6 Symbology classes Layer.symbologyType r/o : string Returns: GRADUATED_COLORS, GRADUATED_SYMBOLS, UNIQUE_VALUES RASTER_CLASSIFIED, OTHER Layer.symbology r/o : Symbology Class Example: if lyr.symbologytype == GRADUATED_COLORS : lyr.symbology.numclasses = 10 lyr.symbology.valuefield = POP2007 General notes, can NOT change: - Symbology class - Individual symbols use arcpy.mapping.updatelayer - Classification methods

8 Performance tips Don t keep calling list functions import map as arcpy.mapping item1 = map.listlayoutelements(mxd,wildcard="item1") item2 = map.listlayoutelements(mxd,wildcard="item2") item3 = map.listlayoutelements(mxd,wildcard="item3") Call them once instead and iterate through the items for elm in arcpy.mapping.listlayoutelements(mxd): if elm.name =="Item1": item1 = elm if elm.name =="Item2": item2 = elm if elm.name =="Item3": item3 = elm

9 Performance tips (continued) Or even better, use dictionaries dict = {} for elm in arcpy.mapping.listlayoutelements(mxd): dict[elm.name] = elm dict["item1"].text = "Dictionaries" dict["item2"].text = "are really" dict["item3"].text = "COOL!!!"

10 Authoring geoprocessing tasks with Python scripts Things to consider help topic: Before import arcpy path = r C:\Project\maps... arcpy.mapping.exporttopdf(mxd, path + "\\output.pdf") After import arcpy path = arcpy.env.scratchworkspace... arcpy.mapping.exporttopdf(mxd, path + "\\output.pdf") arcpy.setparameterastext(1,path + "\\output.pdf")

11 Functions in 10.1 for server publishing and printing - ConvertWebMapToMapDocument() - Use with the ArcGIS web APIs for advanced web map printing workflows Web application arcpy.mapping High-quality output (e.g. PDF) - CreateMapSDDraft() - Automate publishing map documents to map services Map document arcpy.mapping Map service

12 Server printing out-of-the-box ArcGIS Server 10.1 and the ArcGIS web APIs support web map printing via print services. - Out-of-the-box print service and template maps ship with Server - Print services sample: Related Session: Supporting High-Quality Printing in Web Applications with ArcGIS for Server 8:30 am Room 15A)

13 Advanced server printing with arcpy.mapping Build web apps with customized versions of the 10.1 outof-the-box print service Web application arcpy.mapping High-quality output (e.g. PDF) New arcpy.mapping method for converting Web Maps to MapDocuments: - ConvertWebMapToMapDocument () - ConvertWebMapToMapDocument (webmap_json, {template_mxd}, {notes_gdb}, {extra_conversion_options})

14 Advanced server printing with arcpy.mapping Full capabilities of arcpy.mapping on the document - Modify content (e.g. replace service layers with local vector data for high quality printing) - Export using custom options - Export data driven pages - Export to PDF and insert additional pages Return a printer-friendly output file (PDF, PNG, etc.) Online help and examples

15 Demo: High quality server printing with arcpy.mapping Print high quality vector layers instead of tiled image cache of service layers Vector layers will be staged in template map documents Map service tiled cache Vector data

16 Demo: High quality server printing with arcpy.mapping Reference the custom arcpy.mapping based GP service

17 Demo: High quality server printing with arcpy.mapping Arcpy.mapping code used in custom geoprocessing service Get web map JSON Get template MXD 1 Create new MXD based on web map Remove service layers Export PDF Output file of job 2

18 High quality server printing with arcpy.mapping Two tutorials: - Basic high-quality web map printing: - Advanced web map printing: Georeferencing Layers in map Layers in legend

19 Publishing map services with arcpy.mapping arcpy.mapping.createmapsddraft() Workflow from map document to map service Use python for: - Publishing automated analysis results - Scheduled service upgrades - Batch migration from 10.0 to 10.1 Prepare MXDs (arcpy.mapping) arcpy.mapping.mapdocument() Create SDDraft and edit XML (arcpy.mapping) arcpy.mapping.createmapsddraft() Stage and Publish Map Service (arcpy server GP tools) arcpy.stageservice_server() arcpy.uploadservicedefinition_server()

20 Publishing map services with arcpy.mapping Sample: CreateMapSDDraft (arcpy.mapping) Reference a MXD Server connection, service properties, etc Create and analyze sddraft for errors, warnings, etc Stage and publish Map Service Don t publish if errors exist Online help:

21 Publishing other service types with python 10.1: - arcpy.createmapsddraft() 10.1 sp1: - arcpy.creategpsddraft() - Create geoprocessing services with Python - arcpy.createimagesddraft() 10.2: - Create image services with Python - arcpy.creategeocodesddraft() - Create geocoding services with Python
