2. Something cool … http://maps.google.com

3. Google Maps API Live earthquake mapping http://earthquakes.tafoni.net/ Other cool Google Maps API examples:

4. More Google … • Search full text of bookse.g. http://books.google.com/books?q=uml • Calculator • Search tips & Hidden features • Also look for Google Code, Drive & Translate

5. Google Earth ( http://earth.google.com )

6. MXD, Maps, Layers arcpy.mapping Classes

7. Without opening ArcMap, wouldn’t it be nice to • Get or update • MapDocument (MXD) properties • e.g. title, keywords, relative path, author, etc • DataFrame properties • e.g. name, coordinate system, etc. • Layer properties • e.g. name, visibility, data source, symbology, etc. • Layout element properties • e.g. size, position, • Add, remove, move, and update layers • Save MXD or LYR to earlier version for distribution • Build PDF map books • e.g. Export to PDF or insert into existing PDF

21. Finding a specific layer in a DataFrame

22. Working with Layers • arcpy.mapping can’t • Create new map layers in DataFrame or .lyr files from scratch • Change all layer properties in a script • arcpy.mapping can • Add lyr file to DataFrame & change selected layer properties • dataSource, definitionQuery, etc. (see “(rw)” on previous slide) • Apply symbology from existing lyr files to existing layers in DataFrame

23. Adding a Layer to a DataFrame

25. Fixing broken data sources

26. Methods for fixing broken data sources MapDocument.findAndReplaceWorkspacePaths(find_workspace_path, replace_workspace_path, {validate}) MapDocument.replaceWorkspaces(old_workspace_path, old_workspace_type, new_workspace_path, new_workspace_type, {validate}) Layer.findAndReplaceWorkspacePath(find_workspace_path, replace_workspace_path, {validate}) Layer.replaceDataSource(workspace_path, workspace_type, dataset_name, {validate}) TableView.findAndReplaceWorkspacePath(find_workspace_path, replace_workspace_path, {validate}) TableView.replaceDataSource(workspace_path, workspace_type, dataset_name, {validate})

27. Fixing broken data source examples Update all workspace paths to new folder and save to new mxd. Update all workspace paths for all the mxd’s in a folder from local system to UNC paths

37. PDFDocument.appendPages Example

38. Working with arcpy.mapping scripts • Python Window has nice help … but pain for defining/calling functions, debugging, etc. • Edit in PyScripter and use Load …

39. Help is not perfect Should be: Find the MAPSURROUND_ELEMENT with the name "ScaleBar" and move it's x position (relative to its anchor point) to the center of the parentDataFrame.  Save this change to the MXD. Update: ESRI listened to me:
