How Much Do Purdue's Trees Weigh? Estimating Biomass In Urban Areas, Jacob Klaybor, Gillian Clark, Brady Hardiman Nov 2018

How Much Do Purdue's Trees Weigh? Estimating Biomass In Urban Areas, Jacob Klaybor, Gillian Clark, Brady Hardiman

Purdue GIS Day

Vegetation plays an important role in urban areas by reducing the urban heat island effect, sequestering carbon emissions, and providing socioeconomic benefits to the surrounding areas. However, the roles and distributions of urban forests have historically been ignored or underestimated. This presentation uses the campus of Purdue University in West Lafayette, IN, as a case study to quantify the aboveground vegetative biomass of campus trees. Tree biomass is calculated with data from the Purdue Arboretum and family-specific allometric relationships based on each tree's diameter at breast height to estimate the total carbon storage available within campus trees. Biomass estimates ...

Economic Resilience And Diversity In Indiana From 2002 To 2016, Santiago Ruiz, Michael Wilcox, Indraneel Kumar

Purdue GIS Day

It is well accepted that recessionary shocks affect long-term patterns of economic growth within regions. For this reason, it is important to understand how regional economies recover and in which extent a shock could be an economic burden in long term. A relevant variable to measure shock’s impact is employment, for two reasons. First, past recessions suggested that in most cases, the decline in employment tended to be deeper than in output. Second, layoffs of workers are key forms of adjustment to which employees seek to reduce costs. Given these, our research aims to understand shifts in employees during ...

Gis To Address Questions In Forest Ecology And Management, Nicolas Picard Nov 2018

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 ...

Earthquake-Induced Collapsed Building Detection With Vhr Synthetic Aperture Radar Images, Fan Wu, Jie Shan, Chao Wang

Purdue GIS Day

"Compared with optical sensors, Synthetic Aperture Radar (SAR) can provide important damage information due to its ability to map areas affected by earthquakes independently from weather conditions and solar illumination. In 2013, a new TerraSAR-X mode named staring spotlight (ST), whose azimuth resolution was improved to 0.24 m, was introduced for various applications. This very high resolution (VHR) data source made it possible to extract detailed information from individual buildings.

We present a new concept for individual building damage assessment using a post-event sub-meter VHR SAR image and a building footprint map. With the building footprint map, the original ...

The Impact Of Management On The Movement And Home Range Size Of Indiana's Eastern Hellbender Salamanders, Emily B. Mccallen, Bart T. Kraus, Nick G. Burgmeier, Rod N. Williams

Purdue GIS Day

Eastern hellbenders (Cryptobranchus alleganiensis alleganiensis) are a large, fully aquatic salamander species distributed throughout watersheds in the eastern United States. In Indiana, hellbenders were once found in tributaries of the Ohio River and the Wabash River but are now restricted to a single river in the southern portion of the state. Monitoring within the Blue River over twenty years has revealed a steady decrease in the total abundance of hellbenders and a shift towards older individuals in the age structure of the population. Concerned over the apparent lack of recruitment, the Indiana department of natural resources performed a series of ...

Predicting U. S. Presidential Elections: From 1900 Until Today, Richard L. Hogan Nov 2016

Predicting U. S. Presidential Elections: From 1900 Until Today, Richard L. Hogan

Purdue GIS Day

This presentation is scheduled for the weekend before the presidential election of 2016. By then, we might all need a break from pollsters and predictions, although we still might be looking for some assurance that this will not be the end of Western Civilization as we knew it. Toward that end, a little historical perspective on presidential elections since 1900, complete with cool maps, of course, indicating partisanship by state, will illustrate several important hypotheses that the data suggest we might incorporate in our efforts to predict the future by explaining the past. Neither candidate has approved this message.
