[edit] Overview

The data in this resource seems to be used for route planning, as there is a heavy emphasis on portals and footprints.

[edit] Section 3

Speculation: Table of some sort used by route planning. Doing anything on a lot (Even changing the level of the terrain) causes this data to grow drastically.

        BYTE unk1
        BYTE unk2
        BYTE unk3
        BYTE unk4
        IF unk1 = 0 OR unk2 != 0 OR unk3 != 0 (There has to be a simpler test than this)
            REP unk4

[edit] Special IDs

In some cases rather than a LOT ID (Which always ends with the last 4 bits 0) the data contains what I've termed a special ID. This appears to use the 8 bytes slightly differently.

BYTE 5
BYTE ID type
WORD
WORD
BYTE level (-1 = pool)
BYTE (Always 0)

However this could all be coincidental, as the typical lot or object ID looks, to the casual observer, like a DWORD followed by two WORDs.

The following ID types have been observed...
