1. Connectivity for Cyclists? A Network Analysis of Copenhagen's Bike Lanes
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : Cycling has been identified as a central element of the solutions to some of the most pressing challenges for today’s cities, such as poor air quality, rising CO2-levels due to emissions from motorised traffic, traffic congestions, and sedentary lifestyles. A high-quality, safe, and widespread network of cycling infrastructure is a key part in the quest to encourage more people to choose the bicycle over the car. READ MORE

2. Database Performance for GIS : A Comparison of Database Schemas for Measurements with Spatial Attributes
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Spatial databases are becoming more and more important. One type of spatial database is a database of measurements, which combine positions with alphanumerical attributes. While these databases are important, little research has been done on them. There is therefore need for research on how to store this type of data most effectively. READ MORE

3. An open source web GIS tool for analysis and visualization of elephant GPS telemetry data, alongside environmental and anthropogenic variables
University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapAbstract : The movement and distribution of ecologically important herbivores such as elephants are of great significance to conservation biologist seeking to understand the fundamental triggers that influence their mobility and the extent to which these parameters affect how they utilize their immediate and surrounding resources. The recent advancement in animal tracking technology coupled with the availability of moderate to high-resolution satellite data, permits scientists to develop elephant cognitive maps of their adjacent environment, thus offering novel opportunities for research in the fields of wildlife movement ecology and the wider conservation biology.

4. Line Graph Utility : A software module for routing
University essay from Mittuniversitetet/Avdelningen för data- och systemvetenskapAbstract : This project was about building a line graph utility, a software module that should read mapdata from a PostGIS database and transform that information into a line graph (edge based graph) that the calling software could use to perform routing decisions. This outer calling application is part of a project (by an anonymized company) for flexible public transportation, that is meant to manage and direct a fleet of vehicles to where the customers actually are, instead of idling at bus stops.

5. Moving objects database models : A comparison
University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)Abstract : Spatiotemporal databases is a domain that in recent years has gained a lot of attention. Spatiotemporal databases combines two types of databases: spatial databases and temporal databases. Spatial databases are designed for storing and processing spatial information efficiently.
