The program cannot continue to call turf.union after using turf.buffer on geojson #2701
Description
Please provide the following when reporting an issue:
- The version of Turf you are using, and any other relevant versions.
v7.0.0
- GeoJSON data as a gist file or geojson.io (filename extension must be
.geojson).
Because the original data set is too large (40+MB), it can't be uploaded. Only some fragments can be intercepted here.
This is a json file that contains two jsons in geojson format{Groove:{some geojsondata},TreePit:{some geojsondata}}
- Snippet of source code or for complex examples use jsfiddle.
var geo_buffer_data = [...groove_data,...treepit_data]
geo_buffer_data = geo_buffer_data.map((x)=>{
let result = turf.buffer(x, 0.000621*2, { units: "miles" });
result = turf.truncate(result,{precision:5,mutate:true})
return result
})
geo_buffer_data = turf.featureCollection(geo_buffer_data)
try {
geo_buffer_data = turf.union(geo_buffer_data);
geo_buffer_data.geometry.coordinates = geo_buffer_data.geometry.coordinates.map((x,i)=>{
return [x[0]]
})
geo_buffer_data = turf.simplify(geo_buffer_data, { tolerance: 0.00001, highQuality: false });
var BufferLayer = L.geoJSON(geo_buffer_data,{
style: {color: "#ffff00"}
})
} catch (error) {
console.log(error)
var BufferLayer = undefined
}- Verify this issue hasn't already been reported, or resolved in the latest alpha pre-release.
I used turf.truncate to truncate five decimal places based on the proposal given in #2258, but this error was still displayed. But if the decimal point is truncated to the last 4 digits, it can work smoothly, but for me, the precision of the decimal point cannot accurately express my geojson data. I want to know what caused this error.
