Linking Luojia 1-01 Nightlight Imagery to Urban Crime

Applied Geography, 2020
Abstract Various environmental criminology theories and empirical studies have linked the urban environment to crime. The crime pattern theory, in particular, argues that edges, either social or physical, affect crime. A recent study has combined both social and physical edges to derive composite edges.

Evaluation of Luojia 1-01 Nighttime Light Imagery for Impervious Surface Detection: A Comparison With NPP-VIIRS Nighttime Light Data

International Journal of Applied Earth Observation and Geoinformation, 2019
Abstract Impervious surface detection is significant to urban dynamic monitoring and environment management. One of the most effective approaches to evaluating the impervious surface is the use of nighttime light imagery. However, little work on this subject was carried out with the new generation nighttime light data from Luojia 1-01 satellite ...
