LBS Based on Final YearStudent Projects - 2015

12 students researching 7 students contributed data to this analysis (2460

data points) Daniel Corah Vishal Patel Amna Almutawa Ishwa Khadka Victor Horecny Shehzaad kashmiri Farondeep Bains

Context

GPS accuracy claim: 95% of all fixes to be <=10m

Thinknear identify the fact that 46% of reported locations are accurate <=

1000m (Q1 2015 Location Score report)

10% error > 100,000m (60 miles) My students’ research indicates (2420

data points) 85% are accurate to <= 25m 2.5% are >= 500m Outliers 1km to 80km

Triggers to Research Project

Further Research

Replicate the research with a standardised set of parameters and values, based on this year’s exploratory research

Analyse with IBM’s Watson Analytics (100k data points + needed) – please volunteer!!

Extend to School projects
