Customization in ARCGIS
Two levels of Customization
• Customizing the Interface
– To create more efficient user interfaces
• For yourself (e.g. grouping frequently used tools)
• For specialized applications (e.g. simplified interface for data entry operators)
– To access capabilities not on the standard interface
• Supplied as part of ArcGIS but not on the standard interface (many!)
• Downloaded from the web
– From ESRI web site, supplied by ESRI or users
– From other web sites
• Developed by you
• Developing Additional Capabilities
– Automating repetitive tasks
– Creating new analytical procedures
Our focus here will be on customizing the interface. GIS 5317
Programming for GIS will focus on developing additional capabilities.

Options for Developing Additional Capabilities
Current Generation—ESRI ARCGIS
• Modelbuilder
– Multi-step, sequential processing of ArcTools, using a visual development
environment which comes as part of ArcGIS
• Python, Jscript and VBScript
– standardized and relatively simple scripting languages for repetitive
processing, including loops and decision trees, using ArcTools
– Python scripts can be generated from Modelbuilder
• Visual Basic for Applications
– Permits writing of VB macros for sophisticated customization and
development within standard ArcGIS (ArcMap/ArcCatalog) interface (and
thus requires license for these)
– may incorporate ArcObjects, the COM compliant software objects out of
which ArcGIS is constructed.
• ArcGIS Engine
– Set of embeddable GIS components (ArcObjects software objects) for use
in building custom applications, independent of ArcGIS interface
– Runs under Windows, Unix and Linux, with support for Java, C++, COM
and .NET

Options for Developing Additional Capabilities
Earlier Generations: ESRI
• MapObjects
– Microsoft COM compliant objects used to incorporate geographic
capability in standard IT applications, introduced around 1997
– Replaced by ArcEngine/ArcObjects
• Avenue
– The proprietary object oriented programming language used for ESRI’s
first GUI based product, ArcVIEW, introduced in 1993,
– Not compatible with ArcGIS 8 or 9
– Most Avenue-based applications have now been replaced with ArcGIS 8/9
equivalents
• AMLs: Arc Macro Language
– The scripting language associated with ESRI’s original ArcInfo product
introduced in 1981
– Can still be run within ArcGIS 9 via:
• ArcInfo Workstation interface
• Via a tool on a toolbar in Arc Map or ArcCatalog

Options for Developing Additional Capabilities
Current Generation—non-ESRI
• Other major GIS software vendors have equivalents to
ArcEngine e.g. MapInfo MapX
• TatukGIS specializes in providing GIS software
component objects (and there are others)
– http://www.tatukgis.com/
• Google Map and Google Earth mashups, combining
your own data and applications with Google Map or
Google Earth using kml scripts (keyhole markup
language)

Customization Dialog Box
• A graphic interface for
customization. To open
– Go to Tools>Customization
– Or, double click on empty
area in a toolbar
• Modify user interface
–
–
–
–
Turn toolbars on and off
Create new toolbars

Add, delete, and move
controls (buttons and menus)
– Manage shortcut keys

• Drag commands, controls, or
macros onto (off) the toolbar

Save Customizations
•
ArcMap has three level of storage
– Normal Template (Normal.mxt):
Affect all documents
– Template (MyTemp.mxt): Affects
all documents using this template
– This Document (Myproject.mxd):
Affects this document only
•
ArcCatalog only uses a normal
template

Examples
• Code for Fixed Zoom-In
• What about Fixed Zoom-out
Dim pDoc As IMxDocument
Dim pEnv As IEnvelope
Set pDoc = ThisDocument
Set pEnv = pDoc.ActiveView.Extent
pEnv.Expand 0.5, 0.5, True
pDoc.ActivatedView.Extent = pEnv
pDoc.ActivatedView.Refresh

AMLs: Arc Macro Language
• The scripting language associated with ESRI’s original ArcInfo
product
• Essentially allows ArcInfo commands to be saved in a text file
and then executed in batch
• Based on the operating system for the Prime minicomputer of
the 1970s
• Conceptually similar to the old DOS .bat files
• Was the only way to be productive in ArcInfo version 7 and
earlier!
• Many AMLs still exist and need to be converted
• Still runs in Workstation ArcInfo
• ArcCatalog will generate and save AML scripts
• With the introduction of scripting capabilities in ArcGIS 9.0,
AMLs no longer useful
– Most AML capabilities can be re-created with python script.

Running an AML in ArcGis Workstation
•
•
Initiate an ArcGIS Workstation session
If necessary, use the CREATWWORKSPACE command to create a workspace
–
•
Use the command WORKSPACE to move into the new workspace
–
•
&TERM 9999
DISPLAY 9999
&ECHO &ON
(directs AML output to your terminal)
(directs any graphic output to terminal—not needed here)
(sends debug info to terminal—turn off with &OFF)
&RUN utd_newtin.aml
After AML finishes, check that AML tasks completed successfully, e.g. use the DIRECTORY TIN
command to list TINs created
–
•
Use Explorer to copy p:\data\p6382\exercises\custom\utd_newtin.aml
Use Wordpad to specify appropriate directory for CREATETIN command
Run the AML with the &RUN command
–
•
c:\usr\ini\custom
Establish the necessary environment for running an AML
–
–
–
•
w
Use a standard text processor (e.g. Wordpad) to create/edit your AML and be sure it is saved as a text
file with the extension of .aml (place double quotes around name in save box e.g. “newaml.aml”)
–
–
•
cw c:\usr\ini\custom
DIR TIN
For practice, run the AML: giscity.aml
–
Issue the command END in the Arc window to close the graphic window.
