Investigation Of Late Roman Settlement On Dana Island, Bogsak Archaelogical Survey Project, Nicholas K. Rauh, Ayman Habib, Evan Flatt, Angus Moore, Gunder Varinlioglu

Purdue GIS Day

Purdue researchers participated in the 2019 season of the Bogsak Archaeological Survey Project in south coastal Turkey. Prof. Ayman Habib and Evan Flatt of CE used a drone to conduct LIDAR and camera mapping of the Late Roman harbor remains of Dana Island (approximately 250-800 AD). The remains, including vast quarry trenches and terraces of houses, cisterns, and churches, are covered in dense, nearly impenetrable garrigue brush, making standard architectural mapping laborious, inaccurate, and hazardous. The results of the LIDAR mapping should reveal a detailed map of obscured remains in real world coordinates, making it possible to map the remains …

Geoannotator: A Collaborative Semi-Automatic Platform For Constructing Geo-Annotated Text Corpora, Morteza Karimzadeh, Alan M. Maceachren

Purdue University Libraries Open Access Publishing Fund

Ground-truth datasets are essential for the training and evaluation of any automated algorithm. As such, gold-standard annotated corpora underlie most advances in natural language processing (NLP). However, only a few relatively small (geo-)annotated datasets are available for geoparsing, i.e., the automatic recognition and geolocation of place references in unstructured text. The creation of geoparsing corpora that include both the recognition of place names in text and matching of those names to toponyms in a geographic gazetteer (a process we call geo-annotation), is a laborious, time-consuming and expensive task. The field lacks efficient geo-annotation tools to support corpus building and lacks …

Economic Resilience And Concentration In Indiana Over 2002-2016, 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, after …

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 of …

Archaeological Investigation Of An Iron Age Fortress On Dana Island, Turkey, Nathan C. Mcburnett

Purdue GIS Day

In this project, the Bogsak Archaeological survey team investigated a fortress on the northern crest of the mountain on Dana Island, located just off the coast of Turkey in the Rough Cilician Region. Although the interior remains of the fortress, consisting of a large number of ceramics and architectural features such as a basilica, were dated to the Late Roman Era, we found that the fortress itself actually predates this. Based on ceramic remains being used as aggregate in the fortress wall, the team was able to date the fortress itself to the Iron Age (Classical Era). GIS software was …

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 …

Teaching With Arcgis Pro, Larry Theller

Purdue GIS Day

For Fall semester 2016 the ABE department moved the course ASM 540 Basic GIS from ArcGIS Desktop 10.2 to ArcGIS Pro 1.3. This software from ESRI has a completely new look and feel, (ribbon-based rather than cascading menus) and is a true 64 bit application, capable of multi-threading, and built on Python 3. After ArcGIS Desktop 10.5 is released, desktop ends and the future release will be ArcGIS Pro; so it makes sense to switch sooner rather than later. This talk will discuss some issues and some observations of that process.
