Comparing Fence Modeling And Mapping Approaches To Support Wildlife Management And Research In Southwest Montana, Simon Albert Buzzard

Graduate Student Theses, Dissertations, & Professional Papers

Fences pose significant challenges to wildlife movement, but their effects are difficult to quantify because fence location and fence type data are lacking on a global scale. We developed a fence location and density model in southwest Montana, USA to provide data to researchers and managers, and test whether previous models could be applied to a new region and retain suitable levels of statistical accuracy. Our model used local expert opinion to inform how road, land cover, and ownership spatial layers interacted to predict fence locations. We validated the model against fence data collected on random 3.2 km road transects …

The Influence Of Landforms And Sampling Approaches On Riparian Buffer Area And Complexity, Houjun Ding

Dissertations, Master's Theses and Master's Reports

A riparian area is a zone of interaction between aquatic and terrestrial ecosystems.

Effects Of Removing Background Soil Reflectance Pixels From Vegetative Index Maps For Characterization Of Corn Responses To Experimental Treatments, Ana Morales, Robert L. Nielsen, James J. Camberato

Purdue GIS Day

In contrast to traditional data collection methods that require manual sampling, vegetative index (VI) maps derived from unmanned aerial vehicles (UAV) imagery are a potential tool to characterize temporal and spatial treatment effects in a more efficient and non-destructive way. Remotely-sensed reflectance data from a growing corn crop contains pixel values associated with the above-ground plant tissue (e.g., leaves, stalks, tassels) and the underlying soil features. Background soil reflectance data potentially reduces the effectiveness of VI for characterizing crop responses to experimental treatments. Removing background soil image pixels from the larger image dataset should improve that effectiveness. The objective of …

Mapping Postcolonial Literature, Matthew Hannah, Yiqui Yan

Purdue GIS Day

Matthew Hannah (Assistant Professor of Digital Humanities) Yiqiu Yan (Undergraduate Researcher) Space and place are incredibly important features of the postcolonial novel and, for writers of the twentieth and twenty-first centuries who are living in former colonies, geography plays an incredibly significant role in navigating issues of identity, language, and nationality. Because the land is such a contested concept in postcolonial writing, we believe that attending to the localities described in literary representations of the land will provide a rich resource for theorizing the relationship between people and places, between colonies and nations. “Mapping Postcolonial Literature” will showcase an interactive …

Growth, Sprawl, And The Contradictions Of Capitalism: San Diego Suburbs And The Speculative Frenzy, 1970-1991, Richard Hogan

Purdue GIS Day

San Diego has become the most beautiful place where nobody can afford to live because speculative growth drives housing prices regardless of the level of supply or demand. How this happened in San Diego County is fairly clear. Marx explained that ground rents (and thereby land prices) increase when capital and labor are invested in the most valuable land and when investment is intensive, with vast amounts of labor and capital focused on the high yield properties to the virtual exclusion of less productive or less valuable lands. In fact, speculative growth between 1960 and 1980 conformed to what Marx …
