Indigeneity and spatial information science

Journal of Spatial Information Science, 2020
Spatial information science has given rise to a set of concepts, tools, and techniques for understanding our geographic world. In turn, the technologies built on this body of knowledge embed certain "ways of knowing." This vision paper traces the roots and impacts of those embeddings, and explores how they can sometimes be inherently at odds with, or ...

SPATIAL AND TEMPORAL VARIATION OF LAND SURFACE TEMPERATURE IN FUJIAN PROVINCE FROM 2001 TO 2015 [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
Land surface temperature (LST) is an essential parameter in the physics of land surface processes. The spatiotemporal variations of LST on the Fujian province were studied using AQUA Moderate Resolution Imaging Spectroradiometer LST data. Considering the

Quantifying the mixed uncertainty for calculating slope from a gridded digital elevation model

Geocarto International
Digital terrain analysis (DTA) using digital elevation models is influenced by two main uncertainties: propagated elevation uncertainty (PEU) from data and truncation error (TE) from the modeling process.

A Method for 3D Building Individualization Integrating SAMPolyBuild and Multiple Spatial-Geometric Features

Sensors
Individualization of buildings is one of the key issues in the establishment of three-dimensional (3D) building models. Most existing individualization methods rely on inefficient manual separation, while deep learning approaches require extensive pre ...
