The study compared mangrove cover and fragmentation pattern change between Peam Krasop Wildlife Sanctuary (PKWS), southwest Cambodia and the surrounding non-protected area between 2014 and 2020 to investigate the conservation effectiveness of PKWS.
Dengue Fever is a potentially fatal illness that is spread by mosquitoes. The spatial statistics tools in ArcGIS was used to better understand the spatial pattern of Dengue Fever in Pennathur, a village in Southern India.
In this lab, we used machine learning in R to classify the presence and absence of a Cactus species. In
addition, a probability surface was created to show where this species is expected to appear.
Three different interpolation methods were used to predict elevations based on sample points. The interpolated DEM from these points was compared to a LiDAR-derived DEM.
Studies have demonstrated a link between alcohol and violent crime. More specifically, neighborhoods with more alcohol sales such as having more liquor stores or restaurants that sale alcohol may experience more frequent incidences of violent crimes. As a result, government agencies are considering limiting access to alcohol in neighborhoods with high crime density by reducing the number of liquor stores and rejecting new liquor license requests.
The map showed where nightlights have turned on and dropped off between 2012 and 2016. Nightlights provide an interesting way to study human activities and spread globally.
The study aimed to find suitable habitats for a hypothetical genetic engineered species l.millipedis using suitability and capability modeling.
Established in 2018, the Koh Rong National Marine Park is the first marine national park in Cambodia. However, no boundary shapefile can be found online yet, so I digitized it and uploaded the shapefile online.
Avenza Maps can be used on mobile devices to capture GPS data. In this lab, I collected GPS locations for Placemarks on UBC campus and recorded a walk. Then I uploaded the data to Google Earth Pro and ArcGIS as KML file for further analysis.
The spatial distribution of crimes in Ottawa occurred between January 2005 and March 2006 was studied using CrimeStat.
