Leveraging Resources

• ToolShareName– A system folder anywhere on your system

• Toolbox– A geoprocessing toolbox (File or Geodatabase).

• ArcMap mxd– ArcMap, ArcScene, or ArcGlobe documents (use relative pathname

option)

• Readme.txt– Brief purpose statement, date, and contact information.

• Doc – Images used in a model diagram

– XML stylesheets for custom Help dialog, external compiled help files (.chm) referenced by tools or toolboxes

– Other files referenced in the help you provide, such as .pdf and .doc.

• Scratch– Intermediate data in models.

– Scratch file geodatabase

• Scripts – All scripts and content used by script tools

• script libraries

• Dynamic link libraries (DLLs) and executables

• ToolData– Small datasets, lookup tables, connection files to ArcSDE

What is Geoprocessing?

• An operation for manipulating GIS data

• Data management and analysis for making

decisions

• Common geoprocessing operations:

– Geographic feature overlay

– Feature selection and analysis

– Topology processing

– Raster processing

– Data conversion


What is Geoprocessing?

• A typical geoprocessing operation:

1. Starts with input dataset(s)

2. Performs an operation on the input

• Tools

• Scripts

• Parameters

3. Returns results as output dataset(s)

• Web Application

• ArcGIS Desktop

• Advantages

– Centralizes data and geoprocessing

– Can be consumed in lightweight Web clients

– Simplifies complex tasks

• Much can be done without programming


ArcToolbox and ModelBuilder

• ArcToolbox– Add Toolbox

– New > Model

• Drag and drop tools onto the Model

• Link components and set properties

• Model components:

– Inputs

– Outputs

– Tools

– Scripts

– Parameters

– Managed datasets

– Intermediate datasets


ModelBuilder Considerations

• Overwrite outputs

• Geoprocessing > Environments

> Workspace > Scratch

Workspace

• Make settings at ArcMap or

ArcToolbox level, not on the

individual Model



• Scratch Workspace

– %ScratchWorkspace% variable

– ArcGIS Server substitutes for

Server Jobs directory at

runtime

Demo


• Feature Set (or Record Set) allow for user input

– Schema determines the feature type


Publishing Considerations

• Drag and drop Model to create a Tool Layer

• Publishing the MXD results in both Map and


– Both Services will always have the same name



• A Toolbox can be Published as a stand-alone Service

– Lacking TOC layers, the Model must point directly to the data

– A Feature Class must be converted to a Feature Layer


• Synchronous vs. Asynchronous

– Asynchronous

• The default setting

• Client can continue

working

• Results are saved on

the Server

– Synchronous

• Client must wait for

process to complete

• Fastest and appropriate

for small result sets



• Toolbox vs. Map

– Toolbox

• Standalone

– Map Document

• ToolLayer



• Geoprocessing services should always be Pooled

– Pooled

• Instance is returned to

the Pool after process

has completed

– Not Pooled

• Instance is dedicated to

a given user

– Editing




Optimization with In_Memory

• Write intermediate data to Computer Memory rather than to Disk

in_memory\results

• Some rules– Tables and feature classes only

– Cannot create feature datasets

or folders

– Good for intermediate data

– Cannot edit or modify features

• Pros and Cons– Consumes internal memory

– Faster than writing to disk

– Too many features can bog-down server

– Deciding factors

• Amount of available RAM

• Number of other applications running on server consuming memory


• Messages can be suppressed by encapsulating Model

into a Python Script


Demo


Geoprocessing Review

• GP Services centralize both data and tasks on the

server

• GP operations can be run through light weight clients

over the web

• Exposes spatial analysis functionality to less

experienced users


• Use %ScratchWorkspace% variable for output paths

• Use a Feature Set for user defined input

– Record Set for user defined records

– Define symbology and schema for Feature Sets

• Important settings:

– Model Parameter

– Add to display

– Managed and Intermediate data

• GP Services can be based on either:

– Stand-alone Toolbox

– Tool Layer within a Map Document




• GP Services can be either:

– Asynchronous

• Client can continue to work

• Results are saved on the Server

– Synchronous

• Client must wait for process to complete

• Fastest and appropriate for small result sets

– Results can be drawn on the server or returned to the client

• GP Services should always be Pooled

• Clients

– Web Mapping Applications

– ArcGIS Explorer

– ArcGIS Desktop
