Advanced ArcMap

For 796/496Drs Badruddin and

Herrington

Page 2: Advanced ArcMap

The Advanced ArcMAP User

• What is an advanced GIS user?– Someone who knows what they are

doing• Can quickly come up with a problem

solution• W/out spending hrs in help• Knows the booby traps• Can make decent results documents

Page 3: Advanced ArcMap

So this course• Is about

– practice, practice, practice– Familiarity with many of the tools etc.

• Data management • GeoProcessing

– Modelbuilder– Python

• Results presentation

Page 4: Advanced ArcMap

Course fociV10 is different than V9.X• The main GUI is very different• But so are many of the specific ops,

tools and their operation • Tables, for example• Data Management• And Help

So the first step is learn the GUI!

HERE IT IS

Page 5: Advanced ArcMap

The Vehicle• The basic vehicle we will use is

Geoprocessing.• what is that???? • Geoprocessing allows you to

automate. GIS tasks to perform spatial analysis and modeling. What?

• http://support.esri.com/en/knowledgebase/Gisdictionary/browse

Page 6: Advanced ArcMap

Dictionary• Geoprocessing: A GIS operation used

to manipulate GIS data. – Geoprocessing operations take an input

dataset, – perform an operation on that dataset, – Return the result as an output dataset

• Geoprocessing allows for – definition, management, and analysis of

information used to form decisions.

Page 7: Advanced ArcMap

Spatial Analysis• Spatial analysis is a set of

techniques for analyzing spatial data.  The results of spatial analysis are dependent on the locations of the objects being analyzed.

Page 8: Advanced ArcMap

Simulation• Simulation is the imitation of

some real thing available, state of affairs, or process. (Wikipedia).

Page 9: Advanced ArcMap

GeoProcessing So; GeoProcessing is the

automation of workflows Based on rich set of tools and a mechanism to combine

tools in a sequence of operations using models and Python scripts.

GeoProcessing can be Spatial Analysis, Modeling, or Simulation

Page 10: Advanced ArcMap

Models & Scripts Put another way, Geoprocessing is

the automation of workflows. A Workflow is just a list of

connected steps for solving a problem

And to be useful the steps have to be proven to work the way you want

Before you use them

Page 11: Advanced ArcMap

Workflow 1. objectives1. Identify Problem2. Identify measureable criteria3. Define data needs• Time and Spatial properties• Extent• Accuracy

Page 12: Advanced ArcMap

Workflow 2: build the database

1. Get the data2. Design and Build the

database3. Add spatial and attribute

data4. Manage/Edit the data5. Test the procedures you plan

to use!

Page 13: Advanced ArcMap

Workflow 3: Analysis1. Define sequence of

operations 2. Do the Analysis3. Evaluate the results4. Refine the Analysis5. Rerun the sequence

Page 14: Advanced ArcMap

Workflow 4: Deliver1. Create products • Maps• Tables• Graphics• Transportable workflow

Quiz

Page 18: Advanced ArcMap

QUIZ 1• What is a Projection?• Which is correct: Long, Lat or Lat,

Long, as order for geographic coordinates?

• What does UTM NAD 27 ZONE 18 mean and where is it?

• What does the term “Layer” mean?

Page 19: Advanced ArcMap

Quiz 2• What are a Feature Class and a

Feature Data Set and how are they different/

• How do you prevent a layer from being selected?

• What is a data frame?• What does “Jenks” mean?

Page 20: Advanced ArcMap

Quiz 3• What will Acres > 100 AND Acres

<200 select from a parcel dataset?• What does the intersect tool do?• What is a raster layer• What does “Project on fly mean”• And how can it be a booby trap?• Does a Feature Class contain

symbolization information?

Page 22: Advanced ArcMap

The Class Structure• Tuesdays and Thursdays 4:00 pm

to 6:30 pm in 310 Baker• Sit only in the first 3 rows.• NO FOOD or DRINK at any time!• Room will be open to you at 3 pm

-- time for Help!

Page 23: Advanced ArcMap

The Schedule: wks 1-6• Weeks 1-6 – basic topics

– V10 interface(s)– Map composition– Table manipulation– Queries– Editing

Page 24: Advanced ArcMap

Schedule wks 6-13• ModelBuilder• Raster Processing• Networks• 3-D Analyst• Python

Page 25: Advanced ArcMap

Individual Class structure• 4 - ~5 – Lecture / discussion / demo• ~5 to 6:30 Lab time for

– Tutorials– Exercises

• Tutorials are assigned but not graded• Exercises assigned and graded.• Tuesday’s assignments are short and are do at

the start of class on Thursday.• Thursday’s are longer and are due at the start

of Tuesday’s class

Page 26: Advanced ArcMap

Help• From inside ArcGIS• From the web directly• http://resources.arcgis.com/conten

t/web-based-help

• Help stuff– Blogs ESRI– Forums http://forums.arcgis.com/

Page 27: Advanced ArcMap

The assignments• Readings – chapters in book, on-line

articles, ESRI help pages• Tutorials – From book, ESRI, or

elsewhere – not graded• Exercises – Generated and graded by

us. Will usually include a workflow, a schema of how you solved the problem, and, usually, a display of the results.

Page 28: Advanced ArcMap

Grading• Exercises – 30%• Final Project – 60%• Random quizzes – 10%

Materials MUST be handed in on time or don’t bother

(Unless you have a dammed good excuse!)
