WPL is the format of the map-related files similar to IPLs from the previous games. It can be edited with WPL Manager.

File Format
Each world placement file starts with one single header followed by the object placement information. The structure for the header is very simple:
4b - UINT32 - Unknown 4b - UINT32 - Instances
The placement information corresponds to the previous instance section of the .ipl files. They have a binary structure like the binary ipl files introduced with San Andreas:
Section 0 - INST
4b - FLOAT - Position X 4b - FLOAT - Position Y 4b - FLOAT - Position Z 4b - FLOAT - Rotation X 4b - FLOAT - Rotation Y 4b - FLOAT - Rotation Z 4b - FLOAT - Rotation W 4b - UINT32 - Model name hash 4b - UINT32 - Unknown 4b - UINT32 - LOD Index (Index of another model in the current file) 4b - UINT32 - Unknown 4b - UINT32 - Unknown
Rotation information as Quarternion
Section 3 - Parked Cars
4b - FLOAT - Position X 4b - FLOAT - Position Y 4b - FLOAT - Position Z 4b - FLOAT - Unknown 4b - FLOAT - Unknown 4b - FLOAT - Unknown 4b - UINT32 - Model name hash 4b - INT32 - Unknown 4b - INT32 - Unknown 4b - INT32 - Unknown 4b - INT32 - Unknown 4b - INT32 - Unknown 4b - INT32 - Unknown 4b - INT32 - Unknown
Section 9 - LODcull
4b - FLOAT - Position X1 4b - FLOAT - Position Y1 4b - FLOAT - Position Z1 4b - FLOAT - Position X2 4b - FLOAT - Position Y2 4b - FLOAT - Position Z2 4b - UINT32 - number of lod models in wdd file 4b - UINT32 - Hash 1 hash 4b - UINT32 - Hash 2 hash 4b - UINT32 - Hash 3 hash 4b - UINT32 - Hash 4 hash 4b - UINT32 - Hash 5 hash 4b - UINT32 - Hash 6 hash 4b - UINT32 - Hash 7 hash 4b - UINT32 - Hash 8 hash 4b - UINT32 - Hash 9 hash 4b - UINT32 - Hash 10 hash 32b - String - Model name 1 32b - String - Model name 2 32b - String - Model name 3 32b - String - Model name 4 32b - String - Model name 5 32b - String - Model name 6 32b - String - Model name 7 32b - String - Model name 8 32b - String - Model name 9 32b - String - Model name 10
X1, Y1, Z1 = lower left vertex position and X2, Y2, Z2 = upper right vertex position
Section 10 - Unknown Zon or Cull
4b - FLOAT - Position X1 4b - FLOAT - Position Y1 4b - FLOAT - Position Z1 4b - FLOAT - Position X2 4b - FLOAT - Position Y2 4b - FLOAT - Position Z2
X1, Y1, Z1 = lower left vertex position and X2, Y2, Z2 = upper right vertex position
XPL
In the XBox 360's version of GTA 4 same files have the extension .xpl. The XPL and WPL formats are same, but due to the fact XPL files are used on the Xenon platform its data is stored in the big-endian order.
