leaflet-csvtiles is a leaflet plugin that load points from tiled csv files, using the amazing PapaParse library.
This plugin was developed mainly for application with Simple CRS, with different CRS the tiles will always be uniformly spaced in lat and lng (so not uniformly spaced in the map see the demo for the problem visualization)
demo (points have no meaning here)L.CRS.EPSG3857
L.csvTiles(url, options, parser)
urlurl template of the csv tiled files.
optionsoptions object (optional)
parserParser function (default to global
function(url || data, config).
The option that can be passed on creation
xInteger index of the column that stores the x coordinates in the csv, default to
0. (x coordinates will be mapped to lng)
yInteger index of the column that stores the y coordinates in the csv, default to
1. (y coordinates will be mapped to lat).
zInteger index of the column that stores the z coordinates (levels/slice/elevation) in the csv, default to
undefined. If set to a a positive integer and the Multi Level handler is enabled the points will be displayed only in the appropriate level.
sizeNumber or Number size of the space covered by the csvTiles.
tileSizeNumber or Number size of one tile (same unit as
scaleNumber or Number, scale to apply to the points coordinates.
boundsLatLngBounds, (in map coordinates) if provided the
scaleparameter will be computed to fit the points into the given
localRSboolean, if points are given in local (tile) coordinates in each tile, that is if true it means that in every tile the points coordinates range between (0,0) to tileSize.
originoffset of the points coordinates, will be computed automatically if
offsetoffset of the tile indexes.
minZoommin zoom at which the layer is shown.
gridif a grid showing tiles borders should be plotted.
typeOfPointString one of
the following fields are relative to the appropriate type of points used:
the following fields are as in the PapaParse configuration:
Return a vector of reference objects (see
point = [lng,lat,level]
