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 …

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 footprints …

State emergency management agencies are also collaborating with their state cultural agencies to protect these valuable and vulnerable resources. The resulting emergency networks better position the local community and the state to …

Lessons Learned From Culture In Crisis; Or Protecting The Past To Save The Future, Laurie Rush

CHAR

At the midpoint of the second decade of the 21^st century, the world is experiencing deliberate destruction of cultural property at a scale not seen since the Second World War. Future protection and preservation of cultural heritage depends on learning from tragedy and applying these lessons as pro-actively as possible. First, we are discovering that no matter the threat, there are people who risk their lives to save artifacts and features of their culture, and the motives for this courage are retrospectively clear. For a community to survive a conflict or disaster as a corporate entity, elements of shared …

Informing Responders Using Gis And Gps, Deidre Mccarthy

CHAR

Hurricane Katrina devastated the Gulf Coast in August 2005 and created the single largest disaster for cultural resources that the United States has witnessed since the inception of the National Historic Preservation Act (NHPA) in 1966. Notably, the NHPA created the National Register of Historic Places, our nation’s catalog of important cultural resources. The NHPA also stipulates that any federal undertaking which may adversely affect National Register eligible resources be mitigated. For the Federal Emergency Management Agency (FEMA), Katrina created the largest compliance project ever under Section 106 of the NHPA.

Although causing a great deal of damage, Katrina also …

Opening Keynote Address: Using Data To Understand Cultural Destruction, Brian I. Daniels

CHAR

Brian I. Daniels, Ph.D, Penn Cultural Heritage Center, University of Pennsylvania Museum.

Why is cultural heritage targeted in conflict? Under what circumstances? By whom? Today, due in part to the recent notorious instances of cultural destruction in the Middle East and North Africa, there is perhaps more attention among the broader scientific community than ever before about the phenomenon of cultural loss. At the same time, there are many significant data and analytical gaps. Little social science literature about cultural destruction exists and many critical questions—and avenues of research—are, as of yet, unstudied. A primary reason for this lack …

Finding, Organizing, And Creating Spatial Data, Sarah Watson

Research Data and Scholarly Communications Committee Workshops

To produce a compelling and attractive map, it is necessary to have quality data. However, finding quality data and using it to prepare maps can be quite challenging. This workshop will begin with a review of different types of spatial data, how to access it, and strategies for understanding and organizing it. We will then focus on creating our own data by georeferencing scanned paper maps. Georeferencing involves assigning geographic coordinates to images (e.g., maps, aerial photos) that lack a defined coordinate system. Georeferencing helps us locate where an image is located in the world so we can effectively use …
