Lab Assignment 5 – Geoprocessing Service
Due Date: 01/24/2014
Overview
Geoprocessing is one of the original purposes or functions when GIS was invented. It provides
tools and a framework for performing analysis and managing/processing the data. In Desktop
GIS, geoprocessing provides a large suite of tools for performing GIS tasks that range from
simple buffers and polygon overlays to complex regression analysis and image classification.
To share the geoprocessing work (e.g. models) and data used, you can create a geoprocessing
package which can be e-mailed to your colleagues or uploaded to arcgis.com where they can
reach a broad audience. In that sense, it can be considered Web GIS.
You can also create web services based on your geoprocessing workflows. These geoprocessing
services can then be consumed by ArcGIS for Desktop, ArcGIS Explorer, and any web GIS
applications.
This lab assignment is designed to help you become familiar with creating georprocessing
services and also different options for consuming these products.
Specifically, this assignment is divided into four parts:
Part I: Authoring Geoprocessing Workflows
Part II: Creating Geoprocessing Packages
Part III: Publishing Geoprocessing Services
Part IV: Consuming Geoprocessing Services
Part I: Authoring Geoprocessing Workflows
Geoprocessing is an important part of Desktop GIS. I assume that you are familiar with the
common geoprocessing tools and also the working environment (e.g. ModelBuilder).
Even if you know geoprocessing well, I still recommend that you brush up on this topic from the
links below. Why? There have been significant new development or changes from the previous
versions to ArcGIS 10.1. One of the new developments was about geoprocessing. For example,
in ArcGIS 10.1 and above, you can create geoprocessing package to share your model. Also,
there are major differences in terms of publishing geoprocessing services from 10.0 to 10.1 and
10.2.
Therefore, I highly recommend you to update your knowledge by reading more from the ArcGIS
Resources web site.

The first step is to create a map document.
Then, you will need to create a geoprocessing workflow. In this case, I created a model using
ModelBuilder. The workflows of this geoprocessing tool are:
1. Click anywhere on the map to identify a point
2. Define a search distance
3. Identify all the hospitals within the search distance of the point
4. Display the selected hospitals on the map automatically
Here below is the model that I created. I have posted a copy of this model so that you can use
and customize. You can also feel free to create your own model when working on this
