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 …

Is Corruption Influenced By Human Development Index And Transparency? A Global Spatial Assessment Using Gis, Seyedali Ghahari, Shabnam Ghotbi, Samuel Labi, Nader Naderpajouh

Purdue GIS Day

The intricacy of the construction practices sometimes causes the vague atmosphere between clients, partners, and providers, is one of the Achilles heels of infrastructure projects; this grounds the industry as the most inefficient, corrupted business in the world. Governments, in recent years, have made a significant positive effort on public transparency. E-government is an effective tool to execute the very subject. Not only e-government helps transparency, but also it provides openness, accountability, the participation of citizens, etc. By giving citizens access to the functionality of public organizations and institutions, and providing open media for public debates, nations can obtain higher …

Using Gis To Determine Locations For Safety Improvements, Mario Romero, Etienne Tino Atisso, Taojun Wang, Laura Slusher, Andrew Tarko

Purdue GIS Day

Crash location is a critical piece of information for any type of safety-related analysis; however, there is often a high percentage of error in crash latitude and longitude coordinates. Currently, a time-consuming, manual process is used in Indiana to correct faulty crash location coordinates. The Crash Location Improvement Program (CLIP) is a tool developed by the Purdue University Center for Road Safety, with support from Indiana LTAP, which allows users to quickly and easily identify and correct crash coordinates, allowing for a more accurate safety analysis. After correcting the coordinates, crash location maps, heat maps, and other visualization tools are …

Les Rues Des Tableaux: The Geography Of The Parisian Art Market 1815-1955, Léa Saint-Raymond, Félicie De Maupeou, Julien Cavero

Artl@s Bulletin

Building upon a preliminary socioeconomic analysis of the art dealers in Paris between 1815 and 1955 (ARTL@S Bulletin 2, n°2), this paper presents the findings of a spatial study of the Parisian art market in this period. Using serial geographical data drawn from a single, consistent source – the Bottin du commerce – we mapped the spatial evolution of art dealers over 140 years, using a geocoding system with composite locators. The article explores the different spatial dynamics of this market, and seeks to shed light on the links between the evolution of the Parisian economy as a whole and …

Les Rues Des Tableaux. Géographie Du Marché De L'Art Parisien (1815-1955), Léa Saint-Raymond, Félicie De Maupeou, Julien Cavero

Artl@s Bulletin

Continuation of a first socioeconomic analysis of the "art dealers" in Paris between 1815 and 1955 (Artl@s Bulletin 2, no. 2), this paper presents the results of a spatial study of the Parisian art market at that time. Departing from serial geographical data given by a homogeneous source, the Bottin du commerce, we mapped a 140 years spatial evolution of the "art dealers", using a geocoding system with composite locators. The article exposes the spatial dynamics of this market and studies them in a multi-scalar way, making the connection between the global evolution of the Parisian economy and …

Lower Tropospheric Temperature Variability Over The Usa: A Gis Approach, Souleymane Fall, Dev Niyogi, Gilbert L. Rochon

GIS Day

We use the high resolution North American Regional Analysis (NARR) dataset to build for the United States a Temperature Change Index (TCI) based on four contributing variables derived from the layer-averaged temperature and lapse rate of the 1000mb - 700mb layer (near-surface to 3000 meters) for the 1979-2008 period. The analysis uses Geographic Information Systems (GIS) methods to identify distinct regional patterns based on aggregate temperature trends and variability scores. The resulting index allows us to identify and compare regions that experience high (low) temperature trends and variability that are referred to as hot spots (cold spots). The upper Midwest …
