Plant biodiversity hotspots mapping and prioritization in the Bulgarian floristic region Eastern Balkan Mountains

The main goal of the present study was to create a dynamic map of plant biodiversity hotspots of the Bulgarian floristic region Eastern Balkan Mountains. A GIS model, as well as a weighted value scheme for scoring each area, were created in order to identify and to prioritize the hotspots. A total number of defined hot spots of phytodiversity was 34. They were categorized into five classes, based on the cumulative weighted value scheme, and were indicated on the map using color scale. The territories into category I predominated, contrary to preceding investigations of the Black Sea coast and northeastern Bulgaria where category V predominated. In addition, an attempt to refine the borders of the floristic region was made.

Inventory of onshore petroleum seeps and stains in Greenland: a web-based GIS model

A new inventory on onshore petroleum seeps and stains in Greenland has been released by the Geological Survey of Denmark and Greenland as a web-based GIS model on the Greenland Mineral Resources Portal: Petroleum Seeps and Stains in Greenland. Knowledge on oil and gas seeps, oil stains and solid bitumen occurrences provides key information on mineral and petroleum systems, especially in frontier basins. As the understanding of recent and previous migrations of fluids and gases is important for both mineral and petroleum explorations in Greenland, this new inventory has been developed to facilitate exploration and new activities. The classification includes the following types of occurrences: (1) oil seeps, (2) gas seeps, (3) mud diapirs, pingos and gas-rich springs, (4) oil stains in volcanics, carbonates and sandstones, (5) solid macroscopic bitumen and (6) fluid inclusions and other evidence of micro-seepage. The inventory comprises detailed information on localities, coordinates and sample numbers. It also includes descriptions of features and geology, references to data, reports and publications. All information is summarised in either a mineral or petroleum systems context. Petroleum seeps and stains have been reported from most Palaeozoic, Mesozoic and Cenozoic basins in Greenland where they add important information on petroleum systems, especially distribution and facies variation of source rocks, petroleum generation and later migration, accumulation, remigration, uplift and degradation. The inventory is designed to be updated with additional localities and descriptions and new organic geochemical data. This paper provides a general overview of classification, nomenclature, organisation and content of the inventory. We introduce the regional distribution of petroleum seeps and stains in Greenland and general interpretations in the context of mineral and petroleum systems.

Research on Epidemic Prevention and Management Measures in University Based on GIS and ABM – Taking South China University of Technology (Wushan Campus) as an Example

Prevention and management of epidemic is a protracted war. As large community in city, universities are key regions in the anti-epidemic period. However, the current epidemic prevention and management measures in many universities do not compatible with the spatial form and the characteristics of the population, likely to lead to waste of resources and cause conflicts. The research simulates campus environment by constructing GIS model, and simulates the behavior of campus crowd by ABM. Under the coupling effect of the two, the real-time calculation of the spread of epidemic in universities can be calculated in real-time, making up for the deficiency of GIS model which can only do static data analysis. On this basis, research takes South China University of Technology as an example and assumes three epidemic prevention management measures, i.e. closed-off management, zoning management and self prevention, respectively to simulate the spread of the epidemic, sum up the results of different management measures and provide certain suggestions.

Applications of 5D CAD for Billing in Construction using GIS

A Construction project involves project management and financial planning at various stages right from the concept stage to the execution stage. This involves a large number of people working on different aspects of the project adhering to their specific job roles in collaboration with the others. These members not only work on the different aspects but also work on different software’s and platforms in order to create a holistic working plan to ensure timely and flawless construction activities. But these software’s only provide specific information feeded to it. A single program which would provide information of all these software’s collectively on one platform would not only make it convenient for sharing data but also help in reducing the delay and eliminating errors. A 5D model can be created linking the schedule of the project and the cost involved in it to the drawings on a GIS platform. In this research a 5D model of a Residential cum Commercial project Located in Prabhadevi, Mumbai, Maharashtra, India has been generated. This model includes the data related to the Schedule and Cost of the project, which can help in making decisions related to monetary aspects, Men & Material preparedness, verification of bills & Billing Audits. A 5D model holds Spatial data such as Project Schedule, Itemized Element costs and Quantities along with the 3D model of the structure. The conclusion of the study states that a GIS Model can serve as a real time data base for all the parties involved in the project at every level of its progression.

From Archive to GIS: Recovering Spatial Information for Tholos IV at the Palace of Nestor from the Notebooks of Lord William Taylour

This article is a case study in doing new things with old data. In 1953 Lord William Taylour directed the excavation of a monumental vaulted tholos tomb known as 'Tholos IV' at the site of ancient Pylos, Messenia, Greece. The excavation was conducted over two months, during which detailed notes were recorded in three notebooks now kept in the Archives of the American School of Classical Studies at Athens. The formal publication of Tholos IV, however, contains only a basic narrative of the excavation, offering neither precise detail on stratigraphy, object find spots, nor even a complete inventory of small finds. The present study goes back to the original notebooks kept by Taylour and combines the data contained in them with a new digital survey of Tholos IV to produce a comprehensive and accurate 3D GIS model for the excavation. Furthermore, the GIS has been produced in such a way that its dataset is compatible with new excavation data currently generated in the ongoing Palace of Nestor Excavations (PONEX) project, bringing together two excavation campaigns conducted under very different circumstances, methodologies, and recording protocols. Discussion follows on how the production of this GIS deepens our understanding not just of the legacy excavation, but also of the site and its wider landscape.

Tracing the Source of Ocean Trash

Ocean trash is an emerging environmental crisis causing plastic gyres and polluted beaches, but there are only a limited number of models available for ocean trash tracing. This project created a database from Ocean Surface Current Analysis Real-Time (OSCAR) third degree resolution data with data transformation, aggregation, calculation, and expansion, and developed a GIS model for tracing potential trash sources given a location where the trash is spotted on a beach or in an ocean. The GIS model was developed as an ocean trash tracing Python script tool in ArcGIS Pro, which was then published as a geoprocessing tool in ArcGIS Server. The geoprocessing service was embedded in a web application where users can input the starting locations and see potential travelling routes of ocean trash. This project also developed an intuitive web application for the public to trace possible trash sources and raises the awareness of the ocean trash crisis.
