Transforming geodesic latitude, longitude coordinates to geocentric X, Y, Z coordinates and back again.
'''
Define an ellipsoid by its semi major axis (a) and flattening (f).
The definition of the ellipsoid is then saved in the instance object and the functions can be called with just the coordinates to be transformed.

Converts a p5js graphics object to an Image object. This way you can use an off screen buffer to create image masks.
function graphicsToImage(graphics){
var img = createImage(graphics.width, graphics.height);
img.loadPixels();
graphics.loadPixels();
for(var x = 0; x < img.width; x++){
for(var y = 0; y < img.height; y++){
idx = 4 * (y * img.width + x);
img.pixels[idx] = graphics.pixels[idx];
img.pixels[idx+1] = graphics.pixels[idx+1];

Skapa, hosta och ta in mbtiles

Stegen jag tog, hade inget vidare syfta än att få upp ett fungerande exempel.

  1. Ladda ner vägkartan stockholm från lantmäteriets öppna data ftp (vem fan har en ftp 2017?)

  2. Konvertera samtliga *.shp till *.geojson. Använd convertall.sh. Kom ihåg att lägga till -s_srs EPSG:3006 -t_srs EPSG:4326 för att reprojicera till wgs84 i samma veva.

  3. Slå ihop alla *.geojson som ska vara med som lager i *.mbtiles filen med cat *.geojson > vagk_01_wgs84.geojson

  4. Använd Tippecanoe för att konvertera vagk_01_wgs84.geojson till mbtiles.
