Kernel density estimation and hotspot mapping
Policing: An International Journal of Police Strategies & Management, 2014Purpose – The purpose of this paper is to examine the effects of user-defined parameters settings (e.g. interpolation method, grid cell size, and bandwidth) on the predictive accuracy of crime hotspot maps produced from kernel density estimation (KDE).

Crime Hotspots: An Evaluation of the KDE Spatial Mapping Technique
2015 European Intelligence and Security Informatics Conference, 2015Residential burglaries are increasing. By visualizing patterns as spatial hotspots, law-enforcement agents can get a better understanding of crime distributions and trends. Two aspects are investigated, first, measuring the accuracy and performance of the KDE algorithm using small data sets. Secondly, investigation of the amount of crime data needed to

Security Journal, 2008
The recent article by Chainey et al. (2008) in the Security Journal made an important contribution to the analysis of crime hotspots by developing a criterion for comparing methods that identify hotspots. However, the methodology they adopted to compare several specific hotspot techniques was limited and, consequently, raised doubts about the ...

Mapping and Identification of Ecosystem Services Hotspots in the Brazilian Pampa Biome
Environmental ManagementThe intensification and expansion of changes in land use and land cover (LULC) can reduce the availability and quality of natural habitats and ecosystem services (ES). These changes have generated environmental damage in different parts of the world, especially in biomes more susceptible to modifications, such as the Pampa biome in the extreme south of
