 ## 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)
