Land (database table)

''     (back to Database Documentation)

The current structure of the Land table is as follows:

UUID
The unique ID of the Land Parcel.

RegionUUID
The UUID of the region containing this land parcel.

LocalLandID
The number of the parcel.

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
