Contents

[edit] UUID

The unique ID of the Land Parcel.

[edit] RegionUUID

The UUID of the region containing this land parcel.

[edit] LocalLandID

The number of the parcel.

[edit] Bitmap

A block of 512 bytes (4,096 bits) of data with each bit of each byte indicating whether a 4m x 4m piece of a region (the smallest selectable) is in the parcel of land. The block of bytes starts in the bottom left corner of the region, proceeding west-east, south-north. As there are 8 bits in a byte, each byte corresponds to 8 pieces of land in a 256x256 region.

The first bit in the first byte refers to the square piece of land with corners (in region co-ordinates) at:

  • (0, 0)
  • (4, 0)
  • (4, 4)
  • (0, 4)

The first byte corresponds to a rectangle with corners at:

  • (0 ,0)
  • (32,0)
  • (32,4)
  • (0, 4)

The second byte corresponds to a rectangle with corners at:

  • (32, 0)
  • (64, 0)
  • (64, 4)
  • (32, 4)

The ninth byte thus corresponds to a rectangle with corners at:

  • (0, 4)
  • (32,4)
  • (32,8)
  • (0, 8)

To determine if a piece of land in the region belongs to the parcel, one should perform a bitwise operation on the byte, e.g.

  1. byte & 1
  2. byte & 2
  3. byte & 4
  4. byte & 8
  5. byte & 16
  6. byte & 32
  7. byte & 64
  8. byte & 128
