Why The History Lesson?
A Simpler Time
Problems with Wizards
• Wizards cause us to conform
• Options are either preset or
confusing
• Lack of documenting the
process
Familiarity is a Tough Nut to
Crack
Most GIS
Professionals
only know
ArcToolbox
With the Command Line• Freedom to work with the data as you want
• Better understanding of the commands
• Combined with scripting you have a recipe
for future work. AKA documentation!
The “New” Way
• Start up ArcCatalog (wait 2-4 min while it loads)
• Browse for toolbox (clicking through the endless tree)
• Open tool dialog
• Browse for input dataset
• Browse for any optional data for analysis
• Browse for an output location
• Fill out options
• Click OK and pray it doesn’t crash

The “Classic” Way
• Start up Command Prompt (about a second)
• Type simple command (BUILD, CLIP, etc)
• Hit Enter
• Tell everyone how hard it was
Python!
Scripting With GIS• AML
• SML
• Avenue
• Visual Basic for Applications *
• VBScript
• JavaScript
• Perl
• Tcl
• Python
Where is Python Used?
• GIS Applications (ArcGIS, QGIS, Safe FME,
Autodesk)
• Web Frameworks (WeoGeo.com, Google)
• Anywhere (Corel, Civilization, Gmail)
• Become the de-facto scripting language
ArcPy, the New Command
Line• Much like the Arc prompt and AML, ArcPy and Python
give us a powerful analysis and scripting method.
• ArcPy builds on the commands we learned 15 years ago.
• ArcPy is integrated in ArcMap
• Python can be extended to other GIS platforms such as
QGIS.
AML Scripting
in ARC/INFO
clip soils studbndy stdysoil
Python Scripting
in ArcGIS
arcpy.Clip_analysis(soils.shp, studbndy.shp, stdysoil)
Python Scripting With ArcPyimport arcpy
from arcpy import env
env.workspace = "c:/workspace"
#variables
in_features = "soils.shp"
clip_features = "study_boundary.shp"
out_feature_class = "c:/workspace/output/study_area_soils.shp"
xy_tolerance = ""
# Execute Clip
arcpy.Clip_analysis(in_features, clip_features,
out_feature_class, xy_tolerance)

Python
Export to KML
import arcpy
arcpy.CheckOutExtension(“3D”)
env.workspace = "c:/workspace"
# variables
in_feature = "c:/data/TIGER2009/04/ARIZONA/tl_2009_04_county.lyr"
out_feature = "c:/temp/output.kmz"
# Execute KML Export
arcpy.LayerToKML_conversion(in_feature, out_feature,1)
Export to KML
arcpy.LayerToKML_conversion(input.shp, output.kml, scale)
Python Libraries
Rainbows and Unicorns
OK, great…
But what about the future?
Where GIS is headed…
1. Mobile
2. Hosted
3. Specialized
4. Generalized
5. Scripted
6. 3D
7. Responsive
Mobile
Specialized
Generalized

Responsive
It’s teh awesome!
