Improving the accuracy of extant gridded population maps using multisource map fusion
GIScience and Remote Sensing, 2022 Population distribution is the most direct indicator used to describe human activities. Grid-based population distribution maps overcome the drawbacks of statistical data and are thus more suitable for integrated analysis with environmental data. However,

Fusion of Multiple Gridded Biomass Datasets for Generating a Global Forest Aboveground Biomass Map
Remote Sensing, 2020 Many advanced satellite estimation methods have been developed, but global forest aboveground biomass (AGB) products remain largely uncertain. In this study, we explored data fusion techniques to generate a global forest AGB map for the 2000s at 0.01 ...

Neuroscience of Consciousness, 2021 Abstract Neuroscience has made remarkable advances in accounting for how the brain performs its various functions. Consciousness, too, is usually approached in functional terms: the goal is to understand how the brain represents information, accesses that information, and acts on it.

Evaluating the Accuracy of Gridded Population Estimates in Slums: A Case Study in Nigeria and Kenya
Urban Science, 2021 Low- and middle-income country cities face unprecedented urbanization and growth in slums. Gridded population data (e.g., ~100 × 100 m) derived from demographic and spatial data are a promising source of population estimates, but face limitations in ...

Measuring modal accessibility gap using gridded population and network map platform data
Ain Shams Engineering Journal, 2023 Few studies have calculated the magnitude of the modal accessibility gap between public and private transportation (MAG) by taking into account both population characteristics and time-varying characteristics.

Confidence-rich grid mapping [PDF]
The International Journal of Robotics Research, 2019 Representing the environment is a fundamental task in enabling robots to act autonomously in unknown environments. In this work, we present confidence-rich mapping (CRM), a new algorithm for spatial grid-based mapping of the 3D environment. CRM augments the occupancy level at each voxel by its confidence value.
