3D Exercise
- Download Exercise
- Exporting to Google Earth using 3D Analyst and also KML manual editing (for higher resolution)
:: Shortest Path (least cost) analysis will be done in Spatial Analyst.
:: Each team will turn in a KML file, not ArcGIS files. We will discuss ArcGIS 3D Analyst and Google Earth next week.
:: Least Cost Procedure Background
- Run through Military Path demo
- Down data here
Download guide here(incorrect version, will post corrected version after class)- Each team will create a new (and unique) military terrain in the San Juan Mountains.
- Create, by hand:
- Mission Points
- Known/suspected mine fields
- Known/suspected enemy locations
- Edited highway layer
- Please make it possible for other teams to generate a path
- Take into consideration that the path cannot traverse over:
- Water Bodies
- Highways (delete segments to create a passable terrain)
- Teams will then trade these created terrain scenarios.
- Shortest path project will be based on:
- Traverse through the military terrain provided to each team, taking into consideration any of the datasets provided in the San Juan Mountain geodatabase (download from UTA server). The more datasets included in the generated path, the better. The best projects will make unique and creative uses of the various datasets available.
- Why San Juan Mountains and not here in Texas? Our topography is boring.
Turn in a .ZIP file via MavSpace or CD
In the .ZIP:
- + Instructions for me. (I assume you will want me to install the data directly to the c:/ DRIVE)
- + Data
- + MXD (bonus if you create a toolbar with buttons that work)
- + Toolbox
Seems there were some issues with the Erase tool, which is actually a very powerful analysis tool.
I heard over the weekend that it is not available on the student license. Oops, this is correct and I forgot.
I heard right before class that there were SQL errorsd when run. I will investigate this over the week.
Bottom line? Forget about the homework. I appreciate all efforts to complete it and I am sure the frustrations just make you all like me *even more*! Everyone gets full credit and I will investigate.

Redo any question you did not answer correctly and resubmit exam next Monday for 1/2 credit of each question missed. For this reason, I will not go over the exam until next week.
By the way, question 9? Most exams that did not earn 100% got this one wrong, and the wrong answers were not all the same. Please note this question simply asked you to multiply the three layers together, nothing more.
EXAM - DATA
Due to the excessively high (in my opinion) numbers of students who have contacted me about not being able to attend this evening's class to take the midterm, I have decided it best to let everyone take the exam as a take-home exam instead of designing customized exam situations for those who cannot make it. I think is the most fair for everyone involved.
So, here is how we will play this one...
At 5:30pm, when class/exam *would* have started, a post will be made on this site with a link to the exam. It will be filled out on the online form that the link will direct you to. The exam must be submitted but tomorrow (10/19) 7pm. At this time the form will be taken offline. No exceptions. Zero. None. This is the most fair I can think to make this and any further problems any students may have will need to be worked around.
As this exam is now completely take-home, there is no need to come to class at 5:30pm this evening. But, of course, you may if you wish take the exam in the classroom during class time. I will not be physically in class this evening (as I do not expect a large showing), but I will be on Meebo chat (IM) to help with any confusions.
Remember the following exam rules:
+ Be Honorable!
+ Open books, notes, internet
+ No working with any others in any way (Be honorable, please do not cheat. Even if not caught, it is never worth it.)
+ GOOD LUCK!
EXAM - DATA
Exam Details:
- In-class
- Open textbook, notes, Internet
- 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
- Create a layer representing the slope of Arlington Quad. If you create 10 equal classes, what is range that represents the highest values (steepest)? [31.92996713 - 35.47774124]
- Data
- projectednad83 file elevation is meters and spatial reference is nad83 (arctoolbox/data management tools/projections & transformations/raster/project raster) - Use UTM NAD1927 Zone 14N -OR- Set data frame to that reference and export raster same as data frame
- 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)? [33,601.44376 - 37,334.9375]
- If you do not have a major roads file readily available,download pizza demo for major roads (arterials)
- 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) what is the minimum number of classes you need to create? and (2) what would be the break points of these classes? [2 classes] [.5 km and max value]
- 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? [convert feature to raster]
- 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? [specify working directory in spatial analyst options]
- 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 highest values? (data) [394,166.8793 - 422,321.6563]

Plan for Today's Class
1. Explore datasets for Coast Guard site selection project.
- Texas General Land Office: GIS (source) (backup)\
- GLO NRI Data
- A good background map (base map) is: Geography Network/Census 2000 ArcIMS layer
2. Class Exercize:
We are the xSkaters and need to find a cool place in Tarrant County to practice our downhill skateboarding.
Criteria (2 cut for abbreviated class):
- Steep slope as possible
Far from major roads- Low number of households
Prefer not to be within .5 KM of schools
- Elevation (prepared NED)
- Major Roads (Texas GLO)
- Number of households (prepared households)
- For those of you who may have concerns about how/where to access the demographic data for your projects, use this file!
- Schools (TEA)
To convert a file's coordinate system, use ArcToolbox/Data Management Tools/Projections & Transformations/
- Review homework & ensure everyone is member of team.
- Introduce the Spatial Analyst Toolbar
- Explore Surface Analysis functions
- Download 30-meter DEM for Arlington Quad from TNRIS. [DIRECT LINK]
- ArcGIS can not read DEM (digital elevation models). It must be extracted to a location on your computer with no spaces in the path. Then use ArcToolbox/Conversion Tools/To raster/DEM to Raster
- Create contour lines, slope, aspect, and hillshade.
- Class Exercise: Where in the D/FW Metroplex should we open a new pizzeria?
- Download materials here
- We will be following (kind of) the Guide_WithoutGeoprocessing.doc.
- Same dataset we used last class and homework.
- E-Book (Using Spatial Analyst) (on-campus access) -- Through page 39. Take screenshot of results of the Quick-Start tutorial (new school) and bring to class.
- Access Book (on-campus only)
- Accompanying Data
- (Add team members on this paper) Write a 1-page paper (as short or long as you need to make it - a single paragraph or two is fine if you hit the following two points) explaining how the site suitability process works. I am looking for two items. First, I want you to explain how the process works...the steps. Second, I want you to provide an example from your research (or personal) interests where site suitability process is applicable.

Welcome to the class!
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.
Here's what I want for us to do:
