When dealing with large amounts of scattered data, sometimes we need to provide a read-only query API to visualize on a map. When the amount of data is too large, say millions, it is not appropriate to return it all to the front end for processing on the browser. Some aggregation should be completed within the back-end service to return the aggregated search to the front end. Here’s how to do this with the MongoDB + tile index in Go.…

I write a package named aqi. Install: go install github.com/ringsaturn/aqi For China’s HJ633-2012 standar: package main import ( "fmt" "github.com/ringsaturn/aqi" "github.com/ringsaturn/aqi/mep" ) func main() { algo := &mep.Algo{} inputs := []*aqi.Var{ { P: aqi.Pollutant_PM2_5_1H, Value: 16, }, { P: aqi.Pollutant_PM10_1H, Value: 88, }, { P: aqi.Pollutant_CO_1H, Value: 0.2, }, { P: aqi.Pollutant_SO2_1H, Value: 3, }, { P: aqi.Pollutant_NO2_1H, Value: 11, }, { P: aqi.Pollutant_O3_1H, Value: 75, }, } aqi, primaryPollutant,…
