| There are several open source platforms for publishing spatial data and interactive mapping applications to the web. Two populars ones are [[https://mapserver.org/|MapServer]] and [[http://geoserver.org/|GeoServer]], which are written, respectively, in C and in Java. | There are several open source platforms for publishing spatial data and interactive mapping applications to the web.

| - | Newer platforms exists, such as [[https://kepler.gl/|kepler.gl]], which were designed for handling large-scale data sets. | ||
| However, these platforms are used for static spatial data and are unable to cope with moving objects. The goal of the project is to extend one of these platforms with spatio-temporal data types in order to be able to display animated maps. | However, these platforms are used for static spatial data and are unable to cope with moving objects.

| The project consists in implementing a multidimensional generalization of the time_bucket function that allows the user to partition the spatial and/or temporal domain of a table in units (or tiles) that can be used for aggregating data. Then, the project consists of performing a benchmark comparison of TimescaleDB and MobilityDB. | The project consists in implementing a multidimensional generalization of the time_bucket function that allows the user to partition the spatial and/or temporal domain of a table in units (or tiles) that can be used for aggregating data.

| - | ===== Distributed Moving Object Database on Amazon AWS ===== | ||
| - | A distributed database is an architecture in which multiple database instances on different machines are integrate in order to form a single database server. Both the data and the queries are then distributed over these database instances. This architecture is effective in deploying big databases on a cloud platform. | ||

| - | MobilityDB is engineered as an extension of PostgreSQL. AWS supports PostgreSQL databases in [[https://aws.amazon.com/rds/postgresql/|Amazon RDS]] for PostgreSQL and in [[https://aws.amazon.com/rds/aurora/postgresql-features/|Amazon Aurora]]. The goal of this project is to integrate MobilityDB with these products. The key outcomes are a comprehensive assessment of which MOD API can/cannot be distributed, and an assessment of the performance gain. These outcomes should serve as a base for a thesis project to achieve effective integration. | ||

| - | MobilityDB is engineered as an extension of PostgreSQL. MS Azure supports distributed PostgreSQL databases using [[https://www.citusdata.com/|Citus]]. We have made successful tests for integrating MobilityDB and Citus on a local cluster. The goal of this project is to repeat this work on MS Azureintegrate MobilityDB with these products. The key outcomes are a comprehensive assessment of which MOD API can/cannot be distributed, and an assessment of the performance gain. These outcomes should serve as a base for a thesis project to achieve effective integration. | ||
