This post is part of a series where we introduce you to the various topics that we cover in the Scholarly Commons. Maybe you’re new to the field or you’re just to the point where you’re just too afraid to ask… Fear not! We are here to take it back to the basics!

So, what is GIS, anyways?

Geographic Information Systems, or GIS as it is often referred to, is a way of gathering, maintaining, and analyzing data. GIS uses geography and spatial data to create visualizations using maps. This is a very useful way to analyze your data to identify and understand trends, relationships, and patterns in your data over a geographic region. Simply put, it is a way of visualizing data geographically and the key to GIS is in spatial data. In addition to spatial data, there is attribute data which is basically any other data as it relates to the spatial data. For example, if you were looking at the University of Illinois campus, the actual location of the buildings would be spatial data, while the type of building (i.e. an academic, laboratory, recreation, etc) would be attribute data. Using these two types of data together can allow researchers to explore and answer difficult questions.

While it can get more complex than that, since this is an introductions series, we won’t go into the fine details. If you want to learn more about GIS and the projects you can do with it, you can reach out to the Scholarly Common’s GIS Specialist, Wenjie Wang.

So, who uses GIS?

Anyone can use GIS! You can use maps to visualize your data to identify problems, monitor change, set priorities, and forecast fluctuations.

There are GIS technologies and applications that assist researchers in performing GIS. The Scholarly Commons has a wide range of GIS resources, including software that you can access from your own computer and a directory of geospatial data available throughout the web and University Library resources. 

If you’re interested in learning more about GIS application and software and how to apply it to your own projects you can fill out a consultation request form, attend a Savvy Researcher Workshop, Live Chat with us on Ask a Librarian, or send us an email. We are always happy to help!

Introductions: What is Digital Scholarship, anyways?

This is the beginning of a new series where we introduce you to the various topics that we cover in the Scholarly Commons. Maybe you’re new to the field or you’re just to the point where you’re just too afraid to ask… Fear not! We are here to take it back to the basics!

What is digital scholarship, anyways?

Digital scholarship is an all-encompassing term and it can be used very broadly. Digital scholarship refers to the use of digital tools, methods, evidence, or any other digital materials to complete a scholarly project. So, if you are using digital means to construct, analyze, or present your research, you’re doing digital scholarship!

It seems really basic to say that digital scholarship is any project that uses digital means because nowadays, isn’t that every project? Yes and No. We use the term digital quite liberally…If you used Microsoft Word to just write your essay about a lab you did during class – that is not digital scholarship however if you used specialized software to analyze the results from a survey you used to gather data then you wrote about it in an essay that you then typed in Microsoft Word, then that is digital scholarship! If you then wanted to get this essay published and hosted in an online repository so that other researchers can find your essay, then that is digital scholarship too!

Many higher education institutions have digital scholarship centers at their campus that focus on providing specialized support for these types of projects. The Scholarly Commons is a digital scholarship space in the University Main Library! Digital scholarship centers are often pushing for new and innovative means of discovery. They have access to specialized software and hardware and provide a space for collaboration and consultations with subject experts that can help you achieve your project goals.

At the Scholarly Commons, we support a wide array of topics that support digital and data-driven scholarship that this series will cover in the future. We have established partners throughout the library and across the wider University campus to support students, staff, and faculty in their digital scholarship endeavors.

Here is a list of the digital scholarship service points we support:

You can find a list of all the software the Scholarly Commons has to support digital scholarship here and a list of the Scholarly Commons hardware here. If you’re interested in learning more about the foundations of digital scholarship follow along to our Introductions series as we got back to the basics.

As always, if you’re interested in learning more about digital scholarship and how to  support your own projects you can fill out a consultation request form, attend a Savvy Researcher Workshop, Live Chat with us on Ask a Librarian, or send us an email. We are always happy to help!

Simple NetInt: A New Data Visualization Tool from Illinois Assistant Professor, Juan Salamanca

Juan Salamanca Ph.D, Assistant Professor in the School of Art and Design at the University of Illinois Urbana-Champaign recently created a new data visualization tool called Simple NetInt. Though developed from a tool he created a few years ago, this tool brings entirely new opportunities to digital scholarship! This week we had the chance to talk to Juan about this new tool in data visualization. Here’s what he said…

Simple NetInt is a JavaScript version of NetInt, a Java-based node-link visualization prototype designed to support the visual discovery of patterns across large dataset by displaying disjoint clusters of vertices that could be filtered, zoomed in or drilled down interactively. The visualization strategy used in Simple NetInt is to place clustered nodes in independent 3D spaces and draw links between nodes across multiple spaces. The result is a simple graphic user interface that enables visual depth as an intuitive dimension for data exploration.

Simple NetInt InterfaceCheck out the Simple NetInt tool here!

In collaboration with Professor Eric Benson, Salamanca tested a prototype of Simple NetInt with a dataset about academic publications, episodes, and story locations of the Sci-Fi TV series Firefly. The tool shows a network of research relationships between these three sets of entities similar to a citation map but on a timeline following the episodes chronology.

What inspired you to create this new tool?

This tool is an extension of a prototype I built five years ago for the visualization of financial transactions between bank clients. It is a software to visualize networks based on the representation of entities and their relationships and nodes and edges. This new version is used for the visualization of a totally different dataset:  scholarly work published in papers, episodes of a TV Series, and the narrative of the series itself. So, the network representation portrays relationships between journal articles, episode scripts, and fictional characters. I am also using it to design a large mural for the Siebel Center for Design.

What are your hopes for the future use of this project?

The final goal of this project is to develop an augmented reality visualization of networks to be used in the field of digital humanities. This proof of concept shows that scholars in the humanities come across datasets with different dimensional systems that might not be compatible across them. For instance, a timeline of scholarly publications may encompass 10 or 15 years, but the content of what is been discussed in that body of work may encompass centuries of history. Therefore, these two different temporal dimensions need to be represented in such a way that helps scholars in their interpretations. I believe that an immersive visualization may drive new questions for researchers or convey new findings to the public.

What were the major challenges that came with creating this tool?

The major challenge was to find a way to represent three different systems of coordinates in the same space. The tool has a universal space that contains relative subspaces for each dataset loaded. So, the nodes instantiated from each dataset are positioned in their own coordinate system, which could be a timeline, a position relative to a map, or just clusters by proximities. But the edges that connect nodes jump from one coordinate system to the other. This creates the idea of a system of nested spaces that works well with few subspaces, but I am still figuring out what is the most intuitive way to navigate larger multidimensional spaces.

What are your own research interests and how does this project support those?

My research focuses on understanding how designed artifacts affect the viscosity of social action. What I do is to investigate how the design of artifacts facilitates or hinders the cooperation of collaboration between people. I use visual analytics methods to conduct my research so the analysis of networks is an essential tool. I have built several custom-made tools for the observation of the interaction between people and things, and this is one of them.

Fall break is fast approaching and with it will be Thanksgiving! No matter what your traditions are, we all know that this year’s holiday season will look a little bit different. As we move into the Thanksgiving holiday, I wanted to share a mapping project to give thanks and recognize the native lands we live on.

Native Land is an open-source mapping project that shows the indigenous territories across the world. This interactive map allows you to input your address or click and explore to determine what indigenous land you reside on. Not only that but Native Land shares educational information about these nations, their languages, or treaties.  They also include a Teacher’s Guide for various wide age range from children to adults. Users are able to export images of their map, too!

Native Land Map

NativeLand.ca Map Interface

Canadian based and indigenous-led, Native Land Digital aims to educate and bring awareness to the complex histories of the land we inhibit. This platform strives to create conversations about indigenous communities between those with native heritage as well as those without. Native Land Digital values the sacredness of land and they use this platform to honor the history of where we reside. Learn more about their mission and impact on their “Why It Matters” page.

Native Land uses MapBox and WordPress to generate their interactive map. MapBox is an open source mapping platform for custom designed maps. Native Land is available as an App for iOS and Android and they have a texting service, as well. You can find more information about how it works here.

If you’d like to learn more about mapping software, the Scholarly Commons has Geographic Information Systems (GIS) software, consultations, and workshops available. The Scholarly Commons webpage on GIS is a great place to get started.

University of Illinois Urbana-Champaign Land Acknowledgement Statement

As a land-grant institution, the University of Illinois at Urbana-Champaign has a responsibility to acknowledge the historical context in which it exists. In order to remind ourselves and our community, we will begin this event with the following statement. We are currently on the lands of the Peoria, Kaskaskia, Piankashaw, Wea, Miami, Mascoutin, Odawa, Sauk, Mesquaki, Kickapoo, Potawatomi, Ojibwe, and Chickasaw Nations. It is necessary for us to acknowledge these Native Nations and for us to work with them as we move forward as an institution. Over the next 150 years, we will be a vibrant community inclusive of all our differences, with Native peoples at the core of our efforts.
