I'm trying to optimize a Mapbox view for long-distance hiking trails, like the Appalachian Trail or the Pacific Crest Trail. Here's an example, which I've oriented by hand, showing the Senda Pirenáica in Spain:    The area of interest, t...
I'm using a Javascript implementation of Fortune's algorithm to compute voronoi cells (https://github.com/gorhill/Javascript-Voronoi). My sites to compute are points on a map (so (lat,lng)). I first made the projection (lat,lng) -> (x,y),...
I need to find the geospatial coordinates of point which is the mean of the distances between all the Features in my GeoJSON dataset. In turf.js both centroid and centerOfMass are presented. The explanation for centerOfMass is that it "takes any...
Methods: I'm currently using turf.js for geoprocessing as part of a broader mapping project; my workflow looks like this:   Pull geojson of census tracts for an entire county Pull geojson tiles of water polygons from OSM for the county area Recur...
I want to calculate collision area of two polygons (rotated rectangles). I want to calculate what area of the polyA is in the collision area (%)....
I'm trying to snap a draggable point to a vector tileset that consists of lines, but I'm not sure if it's possible using a Mapbox vector tileset.  It's essentially the equivalent of this point snapping example that uses turf.js  https...
I have 5000+ LatLng points, and for each of them I would like to find out which feature (region) they belong to. The features come from a kmz layer by Philippe Ivaldi, converted to GeoJSON.  Currently, I am doing this with turfjs in a double for loop...
I have a GeoJson file which has multiple polygons. Something like this.    I use Leaflet to render this GeoJson in a website. I want to draw an outline around the polygoins that envelopes all the polygons. Something like this.   Format of GeoJSOn i a...
I am trying to use the turf-inside() function  of turf.js and leafletjs. I've prepered the basic example with one geojson point and one polygon but I cannot do the same with more than two polygons (geojson). Any ideas?  <!DOCTYPE html> <...
I have a function that sometimes generates a nested array (for multiPolygon purposes). It could look like this:  [   [     [ 10.0, 59.0],     [ 10.0, 59.0],     [ 10.0, 59.0]   ],   [     [ 10.0, 59.0],     [ 10.0, 59.0],     [ 10.0, 59.0]   ] ]   So...
