Inferring Spatial Scale Change in an Isopleth Map
The Cartographic Journal, 2016This study reunites areal interpolation with the isopleth mapping process to construct an inferred larger scale isopleth map. Intelligent areal interpolation is used to construct two types of population density surfaces that are used as inputs for pycnophylactic interpolation of an isopleth surface.

Urban scale mapping of concrete degradation from projected climate change
Urban Climate, 2014Anthropogenic increases in atmospheric greenhouse gas (GHG) concentrations and resultant changes in climate will have significant detrimental effects to urban infrastructure, from both extreme events and longer-term processes. Here we investigate impacts to concrete structures due to enhanced corrosion through increases in carbonation and chlorination ...

Assessing Historical Maps for Characterizing Fluvial Corridor Changes at a Regional Network Scale
Cartographica, 2020Fluvial corridor quality assessment requires that historical data be collected at a regional scale. In this article, our goal is to assess potential map resources to explore riverscape changes at a regional network scale and to define key issues in using an automated vectorization protocol to characterize such changes on such a large scale.

The Perception of Scale Change in Small-Scale Map Series
The American Cartographer, 1981Variations in symbol size, density, and attribute variability (number of classes of city symbols and degree of sinuosity in linework in this case) were examined for their effectiveness in suggesting changes in relative scale between maps. Symbol size and density were both found to produce strong effects, with perceived relative scale varying directly ...

Remote Sensing of Environment, 2013
Accurate estimate of biomass and its changes at local to regional scales are important for a better understanding of ecosystem function, biodiversity and sustainability. In this study we explored the forest biomass prediction and dynamic monitoring from Light detection and ranging (LiDAR) waveform metrics at different key map scales.

Sub-pixel-scale Land Cover Map Updating by Integrating Change Detection and Sub-Pixel Mapping
Photogrammetric Engineering & Remote Sensing, 2015Abstract Coarse-resolution remotely sensed images are high in temporal repetition rates, but their low spatial resolution limits their application in updating land cover maps. Our proposed land cover updating method involves the use of coarse-reso-lution images to update fine-resolution land cover maps.

HOW SOIL MAP UNITS AND DELINEATIONS CHANGE WITH SURVEY INTENSITY AND MAP SCALE
Canadian Journal of Soil Science, 1981It is becoming common for soil surveys to be made of the same area at different intensities and published at different scales. The principles of cartographic generalization are discussed that control the relationships between the map units and delineations on maps made from such surveys.

Retinex Algorithm on Changing Scales for Haze Removal with Depth Map
International Journal of Hybrid Information Technology, 2014In order to improve the traffic visibility in haze weathers, a Retinex algorithm based on the changing scale for haze removal with a depth map is proposed. It requires the haze image dark channel prior treatment to obtain the estimated depth map. Then it is according to the depth map to calculate Retinex scales for different parts of a hazy image ...

The AGROMIX Land Use Change Interactive Map at a European Scale
EURAF 2024 Abstract book. Agroforestry – regenerating landscapes and diversifying production in Europe. 28–31. 5. 2024 Brno. Bohdan Lojka (ed.), Šárka Hoffmannová (ed.)In the face of future climate challenges, it is of the utmost importance to drive the transition towards more resilient and efficient land use in Europe. As part of the work developed in the AGROMIX EU HORIZON project (2020-2024), we aimed to provide broader spatial contexts where agroforestry (AF) could be implemented to increase the environmental ...

The estimation of vegetation changes on the basis of large-scale mapping
Geobotanical mapping, 2007The large-scale vegetation map of preserved area in Dzhanibek Station (the northwestern Caspian Lowland, the southern subzone of steppe zone) has been compared with that compiled for the same territory 50 years ago. The methods of recurring mapping and the special approaches to legend construction are considered.
