Class Plan: Work on Projects

I am running late and am hoping to be in by 730. Maybe earlier, perhaps later. Trying my best... Of course, please feel free to split if you need to. As I specified on November 3, this class was an open research session anyways.

In the meanwhile, take this time to complete your shortest path projects (if they are not yet complete) and begin working on your free-choice individual projects (due: 12/08).

For help obtaining data sources for your projects, take advantage of the resources here: http://libguides.uta.edu/gis

3D Fun Stuff Today!!

1. Task: Focus on Congress Avenue in Austin, TX
1. Create a TIN (Terrain Dataset Concepts)
   
2. Create a 3D Model
3. Create an AVI flythrough
4. Extrude buildings
5. View layers in Google Earth
2. Download Data
3. Definition of a TIN:

1. A triangulated irregular network data model (TIN) is an efficient way for representing continuous surfaces as a series of linked triangles. Although both grids and tins can be used for surface representation, tins are especially useful for representing surface elevation, subsurface elevation and terrain modeling, specially when the represented surfaces are highly variable and contain discontinuities and breaklines.

   A tin is formed by nodes, triangles and edges. Nodes are locations defined by x, y and z values from which a tin is constructed. Triangles are formed by connecting each node with its neighbors according to the Delaunay criterion: all sample points are connected with their two nearest neighbors to form triangles (by using this method the triangles are as equi-angular as possible, any point on the surface is as close as possible to a node, and the triangulation results independent of the order the points are processed). Edges are the sides of triangles.

   Tins are generated from points, polygons and lines. Points used in defining the tin are called mass points. Areas of constant elevation, such as water surfaces are called exclusion polygons. Finally, lines such as streams and shorelines are called breaklines. Breaklines can be either hard or soft. Hard features are things like roads, streams, and shorelines which indicate a significant break in slope. Soft features are things like ridgelines on rolling hills. Ridges like these do not represent distinct breaks in slope but since they separate watersheds you might like to maintain in the triangulation. When a tin is created, mass points become nodes of triangles, while breaklines and exclusion polygon boundaries become triangle edges.

4. Create a TIN from (1) raster and (2) contours
1. Be extremely careful of x,y,z coordinate systems as well as that of the data frame. Let's use NAD_1927_UTM_Zone_14N.
1. Useful Info: 1 foot = 0.3048 meters
   
5. View TINs in ArcScene
1. Drape various TIGER layers by setting the base heights
2. Drape trees (metadata)
   
3. Add the building footprints (metadata)
   
1. Set the base height
2. Set the extrude height
4. Create fly-through video using the Animation Toolbar
6. Export layers to KMZ
1. ArcToolbox/3D Analyst Tools/Conversion/To KML/

1. Each team will create a new (and unique) military terrain in the San Juan Mountains (download from UTA server).

This geodatabase includes basic vector layers (roads, hydrology, administrative from CDOT), the NED (National Elevation Dataset) and GAP land cover layer. The datasets are all clipped to the same extent, in UTM NAD 1983 Zone 13 (except for the NED layer) and include metadata. 400 MB

1. Create, by hand:
1. Points
   
1. Drop-Off Point
2. Pick-Up Point
3. Electric Generator
1. Known/suspected mine fields
2. Known/suspected enemy locations
3. Edited highway layer
   
2. Please make it possible for other teams to generate a path
   
1. Take into consideration that the path cannot traverse over:
1. Water Bodies
2. Highways (delete segments to create a passable terrain)
3. Teams will then trade these created terrain scenarios.

• No sharing or communication during the exam (in-person, texting, chatting, etc.)
• All questions will be straight answers. This means there will be no images printed nor files submitted.
• Partial credit is not to be expected and is available only under specific and unique situations.
• The exam will be given to you in print and online. You will fill the answers on the print paper and submit it.
  

Sample Questions

1. Create a layer representing the slope of Tarrant County. If you create 10 equal classes, what is range that represents the highest values (steepest)?
1. Data (contains both Tarrant & Denton)
2. Create a layer representing the distance (in feet) from major roads in Tarrant County. If you create 10 equal classes, what is the range that represents the highest values (furthest)?
1. If you do not have a major roads file readily available,download pizza demo for major roads (arterials)
   
3. Situation: Particular animal species known to always travel within .5 km of a particular vegetation type. If you were to create a reclassification scheme of the distance to this vegetation type, in order to identify possible locations to find the species, (1) how many classes would you create? and (2) what would be the break points of these classes?
4. If you needed to include population density, that was obtained from the American Factfinder Census website, as an input into suitability analysis, would you use distance-straight line or convert feature to raster?
5. An analyst used the Raster Calculator to multiply two raster layers together. Afterward, he could not locate the generated Grid file to back up his work? What could he have done to ensure that the result of the Raster Calculator will store the result in a folder of his/her choosing?
6. Take these two raster files and compute a weighted average. The weight of the d_roads file will be 25% and the wieght of the income file will be 75%. If you create 15 equal classes, what is the range that represents the most suitable class (highest values)? (data)

Reclassify & Weights for HW

It would save you all a whole heap of time if you take screenshots of your reclassifications/weghts instead of attempting to retype them.

Online Course Access Codes

I only received an email requesting codes from 7 8 11 12 of you so far. 13 14 still to go...

Please send an email as it is impossible to complete the homework without these access codes.

Welcome to the Class

Welcome to the class!

Please note the links to the left of this page

This course is Analysis of Spatial Data, with a strong focus on GIS analysis and the automation of analysis procedures.

This is a practical course. After this course, you will be able to acquire and analyze spatial data for your own research and purposes.

Hold onto your hats folks, because this will be one heck of a 15-week ride!! No doubt it will be a lot of work, but data analysis and GIS is just so dang fun that I promise it will be worth it.

This blog should be checked regularly for any important information, such as changes to my office hours, assignment changes, or class cancellations (but don't hold your breath waiting for that one...).

What does this mean?

This means after this course, you will be able to perform a site selection analysis using weighted average ranking, create an automated model, perform viewshed analysis, perform shortest path analysis, generate 3D terrains, understand basic interpolation techniques, and more. Bottom line is that you will develop an understanding of many of the ArcGIS extensions in order to perform whatever analysis you need. This course will focus most extensively on the Spatial Analyst extension, but will also explore the 3D Analyst and Geostatistical Analyst extensions as well.

What experience do I need?

An introductory understanding of GIS and a basic working knowledge of ArcGIS. This course can, in theory, be taken simultaneously with an intro to GIS course, but it is inadvisable.

How hard will this course be?

A bit challenging. Between homework assignments, projects, presentations, and exams there will always be something to keep you busy. No worries, though, as most projects and presentations will be done in groups. A bit of a warning: The midterm will be challenging. The grade distribution on my midterms are regularly 50% 85+ and 50% 65-.

I understand it will be challenging, but will it be fun?

Yes! All class exercises and projects will incorporate real-world, practical, analysis concepts and procedures. The final project is a project of your own choosing, so you will be able to apply the skills learned to your own research/interests.

This sounds pretty good. I think you are the best instructor ever!

Yep... You're well on your way to earning an 'A' with thinking like that.

Homework (due 09/08)

Homework:

1. Duplicate pizza demo for a new Cici's Pizzeria.
1. Create a Word document containing the (1) reclassification scheme and (2) weights for each layer in the analysis. Also include a screenshot (print-screen and paste) of the generated suitability layer.
2. If you want to follow the walkthrough, use the Guide_WithGeoprocessing.doc.
3. If for any reason you are working on 9.1, use this data instead.
   
2. Learning ArcGIS Desktop (online course): Module 6
   
3. Learning ArcGIS Spatial Analyst (online course): Module 1
1. SEND AN EMAIL REQUESTING YOUR COURSE ACCESS CODES
   

NOTES FOR CICI's HW:

There are 8 layers that the Model takes into consideration when generating the suitability layer. One of these layers is the distance to existing California Pizza Kitchen restaurants. Of course, this layer is not relevant for CiCi's.

If you assign a weight of 0 (zero), this layer is removed from the equation. So you will then have only 7 layers whose weights must add up to 1.0.

It is not necessary to acquire any additional data. You do not need to consider the locations of any existing CiCi's. Yes, many of you can generate a layer consisting of all CiCi's in the metroplex (either through ReferenceUSA or by querying/exporting the existing pizzeria feature class) but we have not yet learned how to integrate it into our analysis.

ESRI Virtual Courses

Each student will be given access codes for various ESRI Virtual Courses.

INSTRUCTIONS:
-----------------------------------------------
1. Go To My Training
Go to http://training.esri.com. Click "My Training." Under My Courses click "My Virtual Campus Courses." If you already have an ESRI Global Account, log in using your username and password. If you do not, click "Create New Account."

2. Start Your New Course
Click "Start a new course". Type your 14-character Course Access Code in the field provided and click "Go." Follow the instructions on your screen.

3. Go To Class
From your course list, click the course title to begin.
-----------------------------------------------

When assigned ESRI Virtual Course modules, bring in hard copies of the certificate to me. Here is an example of a certificate:


After successfully completing the exam, click the certificate button (looks like a little graduation cap) and then click on 'Completed'.

ArcGIS @ Home

Each student will receive a 12 month educational license for ArcGIS 9.2. This software includes single-use code. This means you cannot install the software on more than 1 computer.

When registering the software onb your own computers, you are prompted to specify which extensions you would like to trial. You need to select at least 'Spatial Analyst', '3D Analyst', and 'Geostatistical Analyst'. It does you no harm, however, to simply select all of them.

From ESRI:

Please advise each student to review the site listed below before installing the software:

[ LINK ]

Please also advise the students that as they register the software, they should make sure to write out the full school name in the organization field rather than using any acronyms, the word "Student", or the word "Self". When those words or initials are used, there is a delay in the registration time as it is required that ESRI manually review the registration rather than having the process be completed automatically.

It is advisable that you install ArcGIS 9.2 Service Pack 6. You want the ArcGIS Desktop (ArcInfo, ArcEditor, ArcView) version.

Plan For First Class

Here's what I want for us to do:

1. Discuss syllabus
2. Where to Hang Out on a Friday Night?
   
3. Form teams
   
4. California Pizza Kitchen site selection (automated version)
1. Download data here.
2. Data must be extracted directly to the C:/ drive. (This is the default.)
5. Discuss homework
