ISPRS International Journal of Geo-Information, 2022 Quantitative relations between topological similarity degree and map scale change of multi-scale contour clusters are vital to the automation of map generalization. However, no method has been proposed to calculate the relations.

Geodesy and Geodynamics, 2015 The degree of spatial similarity plays an important role in map generalization, yet there has been no quantitative research into it. To fill this gap, this study first defines map scale change and spatial similarity degree/relation in multi-scale map ...

Large‐Scale Topographic Changes at Erupting Volcanoes Measured by the TanDEM‐X Digital Change Map
Earth and Space ScienceVolcanic eruptions cause large‐scale topographic changes, through the emplacement of lava flows and lava domes, the formation of craters and calderas, and thick ash and pyroclastic deposits.

A vector map of the world’s terrestrial biotic units: subbiomes, biomes, ecozones and domains [PDF]
Vegetation Classification and Survey (VCS), 2023 A vector map of biotic units encompassing the entire terrestrial area of the earth is provided. It contains a hierarchical system of domains, ecozones, biomes and subbiomes, as a large-scale description of the terrestrial ecosystems.

Large-scale mapping of positional changes of hypoxia-responsive genes upon activation [PDF]
Molecular Biology of the Cell, 2021 A high-throughput imaging platform was used to perform a large-scale analysis of the spatial location of hypoxia-responsive genes. The location of some genes changed upon hypoxia; however, they did not correlate with the extent of their activation, indicating that gene positions and expression are not strictly linked in hypoxic gene activation.

Mastering map scale: balancing workloads using display and geometry change in multi-scale mapping [PDF]
GeoInformatica, 2009 This paper builds on a body of European research on multiple resolution data bases (MRDBs), defining a conceptual framework for managing tasks in a multi-scale mapping project. The framework establishes a workload incorporating task difficulty, time to complete a task, required level of expertise, required resources, etc.

The influence of projection transformations on degree of generalization of map contents [PDF]
Zbornik Radova: Geografski institut "Jovan Cvijić", 2009 This is the study about geographic aspect of mathematical projections of the Earth's sphere surface on a flat surface (plane or map) and it's influence on degree of generalization. The cartographic generalization is creative process of generating, but it

Mapping physiology: biophysical mechanisms define scales of climate change impacts [PDF]
Conservation Physiology, 2019 AbstractThe rocky intertidal zone is a highly dynamic and thermally variable ecosystem, where the combined influences of solar radiation, air temperature and topography can lead to differences greater than 15°C over the scale of centimetres during aerial exposure at low tide. For most intertidal organisms this small-scale heterogeneity in microclimates

Remote Sensing, 2020 Forest disturbances are generally estimated using globally available forest change maps or locally calibrated disturbance maps. The choice of disturbance map depends on the trade-offs among the detection accuracy, processing time, and expert knowledge ...
