Keith Mount Liming approached Rade for help with developing an app to assist with their agronomy work.
The app provides employees with a means to plot the pH values of soil samples collected within a field on a satellite image of the field(s) being assessed. Using these samples the app then partitions the field(s) into areas for lime spreading as a Voronoi diagram – the areas can then be manually merged and amended to take into account other land features. When complete the app creates a PDF report of the spreading areas and rates along with the total weight of lime required for application.
Satellite imagery is cached on device for field(s) being sampled to allow offline usage in remote areas. The app uses the Leaflet and Turf.js libraries to display the mapping and manipulate and display the geographic data.
The data collected and created by the app is then synced to a web portal via a bespoke API allowing online access to all data and reports.
