DefaultFormat class

The "default" text format for coordinate and geometry objects.

Rules applied by the format are aligned with GeoJSON.

Examples:

• point (x, y): 10.1,20.2
• point (x, y, z): 10.1,20.2,30.3
• point (x, y, m) with z formatted as 0: 10.1,20.2,0,40.4
• point (x, y, z, m): 10.1,20.2,30.3,40.4
• box (min-x, min-y, max-x, max-y): 10.1,10.1,20.2,20.2
• box (min-x, min-y, min-z, max-x, max-y, maz-z):
  • 10.1,10.1,10.1,20.2,20.2,20.2
• line string, multi point (with 2D points):
  • [10.1,10.1],[20.2,20.2],[30.3,30.3]
• polygon, multi line string (with 2D points):
  • [[35,10],[45,45],[15,40],[10,20],[35,10]]
• multi polygon (with 2D points):
  • [[[35,10],[45,45],[15,40],[10,20],[35,10]]]
• coordinates for other geometries with similar principles

When getting an encoder from text writer format objects this DefaultFormat class provides you can use crs parameter to give hints (like axis order, and whether x and y must be swapped when writing) about coordinate reference system in text output. When crs is available then crs.swapXY is used to determine whether swapping (x/longitude <-> y/latitude) should occur.
