Globally, the absolute number of war deaths has been declining since 1946. And yet, conflict and violence are currently on the rise, with many conflicts today waged between non-state actors such as political militias, criminal, and international terrorist groups. Unresolved regional tensions, a breakdown in the rule of law, absent or co-opted state institutions, illicit economic gain, and the scarcity of resources exacerbated by climate change, have become dominant drivers of conflict (UN. A new era of conflicts, 2022). In the ear of modern technology, data science, machine learning, and AI, the available shall be used to analyze, understand and possibly predict the possibility of conflicts outbreaks in various parts of the world. Moreover, it should provide tools for political scientists to a deeper understanding of political processes and enhance their decision-making processes. This paper focuses on applying data science techniques to process and analyze data in three various data analysis domains: Semantic, Geospatial, and Temporal Analysis. It provides the possible sources of the conflict and other datasets used for the analytics mentioned above. The data is used for research and experimental purposes only. These analytical processes provide the mechanisms to discover the historical data and identify the potential causes of the conflicts.

This paper presents a case of developing open geospatial analysis functions and a processing toolbox as parts of UN Open GIS Spiral 3 activities. A comprehensive study focused on the use of geospatial analysis at the UN operations has been carried out, which covered various UN operations such as situational awareness, security operations, military operations, protection of civilians, epidemiological analysis, and so on. Four requirements on development of 1) primitive geospatial analysis functions, 2) processing toolbox or processing environment like WPS request builder of GeoServer, 3) model builder, and 4) management of the model builder were clarified through the study. By focusing the first and second requirements, a development architecture was proposed based on JAVA and GeoTools. The scope of implementation and its assessment were described. In addition, a use-case introduced a way of using geospatial functions developed in this research to analyse geostatistic factors that affect to occurrence of Ebola disease. Through the use-case study presented in the paper, I would like to share the experiences and lessons about the development of geospatial analysis functions, which would be used as a reference for other developments and applications.

The UN Vector Tile Toolkit (https://github.com/un-vector-tile-toolkit/) is a package of open source tools designed under the UN Open GIS Initiative to enable public basemap providers, such as the UN geospatial information services or mapping organizations of governments, among others, to deliver their basemap vector tiles leveraging the latest web map technologies. The toolkit provides a set of Node.js open source scripts designed for developers to use with existing and proven open-source software such as Tippecanoe, Maputnik and Vector Tile optimizer. The toolkit will help organizations to produce, host, style, and optimize fast and interoperable basemap vector tiles, making them available with various application frameworks. The talk will cover automatic and continuous updates of basemap vector tiles using a continuously updated PostGIS database which stores both the UN mission-specific basemap data and global OpenStreetMap data. The talk also focuses on how the project ensured interoperability with different existing enterprise geospatial software frameworks that use less-advanced web map libraries. The project aims to build a sustainable community of developers that support the provision of fast and interoperable basemap vector tiles.
