Research Labs and Research Areas

Research Laboratories

Organized research laboratories and groups within the area of spatial informatics include:

SCIS is also home to the Spatial Data Science Institute. This collaborative research and scholarly center engages all members of the University of Maine Spatial Informatics faculty, research collaborators across the campus, and cooperating researchers across and among universities nationally and internationally.

Illustrative Research Areas

Graduate students and faculty are engaged in far ranging yet complementary research programs. Many of the projects involve multi-investigator and cross-disciplinary efforts. For specific project descriptions, consult the NCGIA site or some of the example research abstracts. The following are illustrative of general areas within which specific topics are being pursued.

  • Spatio-Temporal Models:  growing amount of data and information have important spatial and temporal dimensions. We need methods to manage, query, and access both dimensions.
    Research areas:

    • Databases for moving objects
    • Location based services
    • Event based models
    • Generic and domain-specific spatial ontologies
  • Geosensor Networks: Networks of small-form sensors with computing platforms and wireless communication streaming live data are deployed in massive numbers in geographical space. Geosensor networks are the next generation environmental platforms that deliver a microscopic view of geographic space. We need advanced methods for building robust, intelligent systems integrate sensing in space and time with understanding events in space and time.
    Research areas:

    • In-network data aggregation and spatial query execution
    • Qualitative and quantitative in-network algorithms to detect and incrementally track events
    • Mobile geosensor networks
    • Field-based foundations and algorithms for sensor data streams
  • User Interfaces and Interactions: As devices get smaller and we need to use them in different environments. New interaction paradigms are needed under the differing conditions.
    Research areas:

    • Sketch interaction
    • Egocentric pointing devices
    • Space-time visualization environments
  • Mixed Reality (Virtual and Augmented Reality): Despite being a relatively new technology, Mixed Reality is one of the fastest growing markets across the globe. It already disrupts a broad-cross section of industries including education, medicine, retail, as well as entertainment and social lives. However, there are numerous areas to improve.
    Research areas:

    • Multisensory technologies (including touch, smell, and taste)
    • Immersion, Presence, and Interaction in VR
    • Human sensory perception and multimodal interaction
    • Human-Computer Interaction (HCI)
  • Information Extraction: Surveillance and monitoring systems generate huge volumes of information. From such data streams we want to identify objects and/or behaviors.
    Research areas:

    • Automated feature extraction from satellite and aerial imagery
    • Detection and tracking of moving objects from imagery
    • Event detection and activity monitoring from time series and space-time series sensing
  • Information Integration: Growing heterogeneous collections of information (maps, images, text, video, time series) need to be integrated and searched for patterns
    Research areas:

    • Semantic similarity models
    • Event data models
    • Metadata models
    • Uncertainty models
    • Logical approaches to semantic integration
  • Information Policy: Access, Security, Privacy, Intellectual Property Rights: As technologies and their interaction with society become more complex, neither technological nor legal solutions uninformed by the other are sufficient.
    Research areas:

    • Ethics driven information systems design
    • Interoperability of legal rights in the use of data
    • Models for internalizing external societal costs in systems design and development
    • Societal needs driven metadata, data provenance and recommender systems.
    • Protecting privacy in pervasive surveillance environments
