Spatial Data Infrastructure Usability Comparison Assignment

Submission Materials

Submission Field :

Student Comments : Hi Dr. Bishop, I apologize for the late submission. I mistakenly thought I had more time to work on this. I appreciate the opportunity to submit this work with a penalty deduction for lateness. I am a bit concerned about how to incorporate literature, which I did not do. If I need to add in references to literature on online mapping usability, perhaps I could use some additional time this evening? In for a penny, in for a pound after all. Thanks, Tanner

Instructor Feedback

Grade : 52.00 out of 60

Comments :

This was done well. Future work would benefit from positioning your thoughts within existing literature. In that way, work you do matters to others. I will make it more clear in future versions of the course by assigning more required readings about usability in the GeoWeb week, including the best example from this class, and providing examples of what I mean by referencing literature. I did expect course materials to inform this first assignment (e.g., Harley, Crampton), but I will work better to help connect the dots in future assignments. For example, using another researchers framework would have been one way to do a usability assignment. Also, headings and subheadings help organize a paper, so you may want to use that structure in future work. The instructions also asked for screen shots and I think you could have used more of those. At least one for each application is what I will add to the directions.


Geospatial Data Discovery Assignment



Efforts at uncovering “global” metadata feature for images in Joomla CMS


I’ve worked a bit on the problem of copyright information and haven’t gotten far on the specific issue concerning copyright information display in the rotating banner.

However, I did confirm a way to add alternative text / title text without necessarily modifying the HTML code. It might make adding meta tags less painful for new images, but will likely not be that helpful in minimizing the pain of adding meta tags to existing images. And, the change is not "global."

Below are my notes on what I looked at today, plus possible next steps:

Click "Image" directly below "Article Manager: Edit Article."

Directory: /stories/documents

Double click on ‘terrapinpic.jpg’

Set Image Description

Diamondback terrapin [Copyright: J.D. Willson, used with permission]

Set Image Title

Malaclemys terrapin [Copyright: J.D. Willson]

Sceen capture taken.

Click "Inset" button.

Code Changes to Below:

<img src="images/stories/documents/terrapinpic.jpg" alt="Diamondback terrapin [Copyright: J.D. Willson, used with permission]" title="Malaclemys terrapin [Copyright: J.D. Willson]" /><h2>&nbsp;</h2>
<p><strong><img style="float: right;" src="images/stories/documents/terrapinpic.jpg" alt="J.D. Willson" width="200" height="150" /></strong></p>
<p><a href="images/stories/documents/Diamondback_Terrapin_Educators_Guide.pdf"><strong>Diamondback Terrapin Educators Guide</strong></a></p>
<p><a href="images/stories/documents/Diamondback_Terrapin_Living_on_the_Edge_Board_Game.pdf"><strong>Diamondback Terrapin Living on the Edge Board Game</strong></a></p>

Refreshed page:

Confirmed that "on hover" works in:


Checked under "Media Manager"

Navigated to Documents
Selected check box for terrapin image

Clicked "Options" – this was a dead end, options for the folder.

Searched Google for ""media manager" AND metadata AND joomla"

"There are other places where the media manager plays a role, like in categories. It is possible to link an image to a category (Figure 7)."

This might be a way of associating images.

For example, could there be a "Private" And "Joe Farah" category, where any image from Joe Farah is added?

I am hesitant to create a new category without fully understanding the settings for categories. All existing categories <> are public.

I used the existing "uncategorized" category:

Added this to "toggle text"

Images Copyright Joe Farah, used with permission.

Added this to "meta description"
Images donated for use by PARC by Joe Farah.

Under "Basic options" i added the collard lizard.

I also added a note: "Note: Image Copyright Joe Farah."

"photography, copyright" to "Meta Keywords" and "Joe Farah" to Author.

This did not appear to have any effect on the image.

I am also not sure if adding meta tags to the image as it appears at <> would impact the appearance of copyright information in the rotating banner on the home screen.

Location of image on TWS award page:

URL for image on pac home page:

For the banner images, J.D. might be right to pursue a CSS solution.

However, I don’t think it is possible to associate metadata with an image on a "global" basis within Joomla. It might be worth posting to a joomla discussion board this problem of "global metadata for an image" or more simply put, write metadata once that appears anywhere the image is used.

Is there anyone who might be knowledgeable about a good Joomla discussion board? I don’t mind to look for one if not.


GIS Training / ESRI Online Courses of Interest

With the upcoming winter break, I noticed UT offers some self-paced virtual training and has a course list online at <>

Looking over the courses offered, I noticed a few I’m interested in that could be useful for my career goals as a data manager for a natural resources organization.

I’m not sure how long each module would take, but I would like to work on a few over the break if it’s possible to work on several in one month.

I saw that course codes are needed and the instructions are to contact the Geospatial Data Librarian.

ESRI Training Courses of Interest:

Basics of the Geodatabase Data Model

Getting Started with the Geodatabase

Archiving Data in a Multiuser Geodatabase

Creating and Editing Geodatabase Features with ArcGIS Desktop (for ArcEditor and ArcInfo)

Creating and Integrating Data for Natural Resource Applications

Basics of Python (for ArcGIS 10)

Python Scripting for Geoprocessing Workflows (for ArcGIS 10)

I’m also not sure how many of these are identical to modules in other ESRI resources, like the GIS workbooks or ArcGIS 10.1 tutorial CDs. However, my home computer does not have an optical drive, so it would be useful to download data directly even if the data is identical to what is found on the CDs.

Biogeomancer Web Site

Hi Michelle,

Thanks for the information concerning the prognosis for the biogeomancer tool.

I learned of it through citations in the literature for a geocoding paper I am working on for a class in geographic information librarianship. The tool might be useful for my expected Masters thesis topic.

If you go to Google Scholar you will see a ton of different links, some to a sourceforge site, some to a google site <‎>, some to

If you search for "" then you will see 31 results in Google Scholar, some papers dated to 2013. There are 226,000 results on a strict search of <""> on Google web search.

While there are various affiliated sites and third-party references to the tool, I was unable to determine the current status. I saw it was listed on the "Current Projects" site for the MVZ so I searched the Berkeley Web site for "biogeomancer" and found this page:

That page in particular links to the site, so I found the MVZ contact information.

Thank you again for the suggestion, although from the frequent mentions of the tool in the literature and open Web, it does seem Biogeomancer was a widely used service.

I regret I was unable to try it out.

Dear Tanner, Biogeomancer is offline with no real prognosis for its revival. For everyone who wants to use if for georeferencing, I strongly recommend GeoLocate. It too has semi-automated georeferencing web portal We use it everyday!

The programming team is quite responsive so dont hesitate to contact them for help or suggestions.

May I ask where you found the bg link?

Thanks for you inquiry, MK

Building Raster Geodatabases

Geography 414 homework assignment from the Raster database lecture.

Better Raster Clipping Options in ArcGIS


Raster Dataset Homework:

  • Get the census tract layer for Hamilton County, TN for TIGER 2010
  • Download the NLCD data from the assignments section of Blackboard
  • Create a raster layer of land cover for those areas that fall within Hamilton County EXCEPT for tracts
    • 6
    • 8
    • 10
    • 15
    • 31
  • Create ppt of screen shot and post on bb

My approach to this is to create a new shapefile that does not contain the census tracts to exclude.

SELECT * FROM tl_2-1-_47065_tract10 WHERE "TRACTCE10" = ‘000600’ OR "TRACTCE10" = ‘000800’ OR "TRACTCE10" = ‘003100’

I’m not sure why 10 and 15 were listed as tracts and will need to ask Dr. Ralston about that in class – perhaps I am looking at the wrong attributes.

In some metadata I found at <TRACTCE10>, "TRACTCE10" is listed as "2010 Census census tract code"

Also, "NAME10" is defined as "2010 Census Tract Name" – this is the census tract code converted to an integer or integer plus two-digit decimal. Still, however, 10 and 15 were not listed as tracts when sorting by ascending in "NAME10" column in the preview in ArcCatalog.

I chose "Switch Selection" and then "Create Layer from Selected Features" to obtain a new layer, minus tracts 6, 8, and 31.

I then used Raster processing – Clip following the guide at <>.

I used <hamilton_nlcd> clipped previously as the input raster. The output raster is <tl_2010_47065_tract10 selection>.

As a final insult – ArcMap froze up on me – so my final product is faded out, but I took a screen capture with Print Screen.


Spatial Databases / Data Management: Building a Geodatabase Tutorial

The ArcGIS Resource center includes a "quick tour of data management" in the professional library:

The building a geodatabase tutorial is within the "Managing geodatabases" and "an overvoew of the geodatabase" subfolder.

I was a bit disappointed this was centered on utilities and am looking forward to working with some natural resources management oriented data.


Program Seeks to Nurture ‘Data Science Culture’ at Universities –

37.8 Million towards creating a “data science culture” at universities. I found this to be a particularly compelling reason to invest in a culture shift:

“Universities are losing much of the top data science talent they produce to industry. We need them back at the universities, working on the world’s most important science problems — not trying to make people click on ads.”
