Hi Folks,
Andrea and Jane pointed me towards some example Drone data [0] which I started playing around with yesterday.
I converted the CSV CO2Meter profile logs (generated by the drone) to Turtle [1] using the Apache Any23 CSV extraction algorithm [2] and made it available in the ESIP COR [3]. This allows simple SPARQL [4] queries to be made using the GUI [5].
The simple sample query below gives us the first ten results from the dataset which have CO2 Concentrations (parts-per-million) of greater than 500 ppm
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX morning1: <file:/usr/local/ESIPDroneClusterSoftware/example/morning1.csv>
SELECT * WHERE {
?sub morning1:Co2Ppm ?value .
FILTER (?value > 500) .
}
LIMIT 10
If anyone would like to learn how I created the Turtle manifestation of the CSV data then let me know and I can detail.
Lewis
