* * `pack.vertices.v`: `number[][]` - indexes of vertices adjacent to each vertex. Most vertices have 3 neighboring vertices, bordering vertices has only 2, while the third is still added to the data as `-1`
## Features data
### Grid object
* `grid.features`: `object[]` - array containing objects for all enclosed entities of original graph: islands, lakes and oceans. Feature object structure:
* * `i`: `number` - feature id starting from `1`
* * `land`: `boolean` - `true` if feature is land (height >= `20`)
* * `border`: `boolean` - `true` if feature touches map border (used to separate lakes from oceans)
* * `type`: `string` - feature type, can be `ocean`, `island` or `lake
### Pack object
* `pack.features`: `object[]` - array containing objects for all enclosed entities of repacked graph: islands, lakes and oceans. Note: element 0 has no data. Stored in .map file. Feature object structure:
* * `i`: `number` - feature id starting from `1`
* * `land`: `boolean` - `true` if feature is land (height >= `20`)
* * `border`: `boolean` - `true` if feature touches map border (used to separate lakes from oceans)
* * `type`: `string` - feature type, can be `ocean`, `island` or `lake`
* * `group`: `string`: feature subtype. The variants are:
* * * `ocean` - is always `ocean`
* * * `island` - `continent`, `island`, `isle` or `lake_island`
* * * `lake` - `freshwater`, `salt`, `dry`, `sinkhole` or `lava`
* * `group`: `string`: feature subtype, depends on type. Subtype for ocean is `ocean`; for land it is `continent`, `island`, `isle` or `lake_island`; for lake it is `freshwater`, `salt`, `dry`, `sinkhole` or `lava`
* * `cells`: `number` - number of cells in feature
* * `firstCell`: `number` - index of the first (top left) cell in feature
* * `vertices`: `number[]` - indexes of vertices around the feature (perimetric vertices)

World data is mainly stored in typed arrays within `cells` object in both `grid` and `pack`.
### Grid object
* `grid.cells`: `{}` - cells data object, including world data:
* * `grid.cells.f`: `number[]` - _features_ indexes `Uint16Array` or `Uint32Array` (depending on cells number)
* * `grid.cells.c`: `number[][]` - indexes of cells adjacent to each cell (neighboring cells)
* * `grid.cells.v`: `number[][]` - indexes of vertices of each cell
* * `grid.cells.b`: `number[]` - indicates if cell borders map edge, 1 if `true`, 0 if `false`. Integers, not Boolean
* `grid.cells.h`: `number[]` - cells elevation in `[0, 100]` range, where `20` is the minimal land elevation. `Uint8Array`
* `grid.cells.f`: `number[]` - indexes of feature. `Uint16Array` or `Uint32Array` (depending on cells number)
* `grid.cells.t`: `number[]` - distance field. `1, 2, ...` - land cells, `-1, -2, ...` - water cells, `0` - unmarked cell. `Uint8Array`
* `grid.cells.temp`: `number[]` - cells temperature in Celsius. `Uint8Array`
* `grid.cells.prec`: `number[]` - cells precipitation in unspecified scale. `Uint8Array`
