Soil Erosion Analysis Of The Monroe County’S Watersheds In Indiana, Danielli De Melo Moura, Jie Shan

Purdue GIS Day

This study was carried out to spatially predict the amount of soil loss (tons/ha/year ) of Monroe County’s watersheds using Geographic Information System (GIS). Revised Universal Soil Loss Equation (RUSLE) was used to estimate potential soil losses by using information such as rainfall data for calculating the rainfall erosivity (R) , soil map for calculating the soil erodibility (K), digital elevation model for obtaining the topography factor (LS) and vegetation/cropland cover for calculating the cover management factor (C) and support practice factor (P). The result of the analysis depicted that the soil loss rate in Moroe’s watersheds ranges from 0 …

The Value Of Open Gis In Higher Education, Christina Hupy

Gis To Address Questions In Forest Ecology And Management, Nicolas Picard

Purdue GIS Day

Geographic Information Systems (GIS) are powerful tools to deal with spatialized issues. As such, they have become routine tools in forestry to delimit forest resources, support the design of forest inventories, map forest resources, and analyze, model and support decision making to sustainably manage forests. Two examples will be provided to show how forest management can benefit from progress in GIS technology. The first one deals with the optimization of forest roads to harvest trees in tropical rainforests. It required the development of heuristics to solve the multiple target access problem in a reasonable time. The second one deals with …

Spatial Information Literacy For Digital Humanities: The Case Study Of Leveraging Geospatial Information For African American History Education., Nicole Kong, Cornelius Bynum, Chrystal Johnson, Jennifer Sdunzik, Xiaoyue Qin

Libraries Faculty and Staff Scholarship and Research

The rise of “digital humanities” and the “spatial turn” in the humanities has generated many new insights in the study of culture, history, literature, and arts. Within this research trend, the library's geospatial service can play an active role by introducing spatial information literacy and technology. In this article, we use the information literacy framework to explore the library's role in supporting digital humanities by introducing a successful collaboration involving a librarian and history and education researchers in hosting a National Endowment for the Humanities (NEH)-funded summer institute for school teachers. Our results suggest that the framework has opened a …

How Gis Will Support Next Gen 9-1-1, Jim I. Sparks

Purdue GIS Day

While most practitioners have a general awareness that GIS will play a more prominent role in Next Generation 9-1-1, few have much definitive information about what that means for Indiana GIS. This presentation will provide background information and an introduction to the requirements that NG 9-1-1 will place on our location data. Time will be left for some discussion centered on the challenges that are ahead of us.

Mapping Religion And Chinese Society, Jonathan E.E. Pettit

Purdue GIS Day

Over the past two decades, the Chinese government has enacted a series of regulations that have made the collection of geospatial data illegal, and have tried to use existing technologies (e.g., cell phone towers, online mapping programs) to avert attempts to map sensitive areas in China. This talks examines the recent work of Purdue graduate students at the Center on Religion and Chinese Society, who have developed a web-based GIS program that provides researchers worldwide a way to make and use accurate data on religious and demographic data in China.

Common Metrics For Web-Based Mapping Applications In Academic Libraries, Ningning Kong, Tao Zhang, Ilana Stonebraker

Libraries Faculty and Staff Scholarship and Research

Purpose – This study aims to establish common metrics for web-based mapping applications to facilitate user decision making and enhance information providers’ product design.

Design/methodology/approach – The metrics were developed from a combination of literature review and case studies. From the literature review, we identified three major areas of assessment for web-based mapping applications. We then studied six online applications to refine the metrics.

Findings – Our results suggest that web-based mapping applications can be evaluated from three major aspects: data content, GIS functionality, and usability. We have developed detailed measures for each factor through our evaluation of the six …

Gis Based Pavement Maintenance: A Systematic Approach, Robert J. Kmetz

Purdue Polytechnic Directed Projects

Abstract

According to 2008 Federal Highway Administration (FHWA) statistics, there are 2,734,102 miles of paved public roads in the United Sates, with an additional 1,324,245 miles of unpaved public roads. Road conditions deteriorate with time as the result of weather effects, deicing salts, and vehicle loads. The most common pavement distress includes cracking, rutting, and potholes. These pavement defects must be repaired to restore the pavement to a satisfactory service level for road users. According to the FHWA, in 2006 approximately $54.2 billion dollars was spent on maintenance and expansion, just on U.S. highways alone.

Routine maintenance is a cost …

Comparisons Between Educational Map Software Displaying Soil Data, Laura A. Kocur

Department of Computer Graphics Technology Degree Theses

The use of technology in the classroom is becoming more widespread, and the area of agronomy is no different. Utilization of various mapping technology is more common in instructional components in the classroom, although the impacts of software usability have not yet been explored. Maps available over the Internet are identified as an area in which usability is not known, nor are there any fixed standards or conventions to govern the display of them. The recently developed mapping prototype is intended to increase accessibility to map data used in class, as well as make it easier to use the data. …

Library Applications, Collaborations, And Courses For Geodata And Geoinformatics, C. C. Miller

International Association of Scientific and Technological University Libraries, 31st Annual Conference

This paper will overview several library GIS and geoinformatics projects, collaborations, and initiatives at Purdue that, taken together, formulate a reasonable plan of attack for geolibrarians interested in tackling some (not all) of the issues rolled up into e-geoscience and geoinformatics. Included as examples are a metadata harvesting/catalog project, collaborations with domain faculty, courses developed and taught, and e-data efforts. From this handful of examples an argument will be made that aggressive and efficient individual geolibrarians can impact and indeed steer geoinformatics and interdisciplinary research efforts project by project, then campus by campus, and simultaneously develop and evolve their library …

Preserving Soil Survey Data With Gis, Christopher C. Miller, Marianne S. Bracke

Libraries Research Publications

Purdue University Libraries are resurrecting a 1906 Soil Survey of Tippecanoe County, Indiana and mashing it with itself in order to add value, access, and interaction beyond the more traditional scan/describe/store model of collection recovery. It is an attempt to leverage the evolving technologies of librarianship (description, yes, but also text markup, web application-building, and geographic information systems [GIS]) toward the benefit of our users' maturing needs and expectations.

This poster provides some context to the materials and the project and documents the process of taking beautiful, important, but underused analog materials and decompiling them in order to re-build a …

JTRP Technical Reports

Design data collection involving the use of Lidar instrument, in conjunction with GPS proves to be very effective. Data required to model two bridges over the I-70 was collected on a single day, involving five and six sessions with Lidar equipment. Even though the data was collected on two bridges, it did not cause any disruption of the traffic, either on the Interstate or on the bridges. A major cause of concern during survey activities, particularly along interstates is safety, both for the motorists as well as the people involved in data collection. Lidar data collection was found to be …
