These files (one per neighborhood/subhood package) describe the trees, roads, bridges and decorations found in neighborhoods/subhoods. This resource has been given the abbreviation NHTR.

In other words, this is how each known type looks:

The X-Y plane has it's origin at the top left of the neighborhood. Positive X's go Right. Positive Y's go down.


Example

A 4 byte header (Always Present)

A 6 byte subsection header for trees (Always present)
n * 38 bytes (where n is the number of trees in the Hood, these are present only if there are trees in the Hood).
A 6 byte subsection header for roads (Always present)
n * 124 bytes (where n is the number of road tiles in the Hood, these are present only if there are roads in the Hood).
A 6 byte subsection header probably for bridges (Always present)
n * 164 bytes (where n is the number of bridge tiles in the Hood, these are present only if there are bridges in the Hood).
A 6 byte subsection header for decorations (Always present).
n * 38 bytes (where n is the number of decorations in the Hood, these are present only if there are decorations in the Hood).

Notes

The co-ordinate system used for the Hoods has 0,0 in the top left hand corner of the Hood when viewed for the first time after importing.

Thank you Quaxi & Jaxad0127 for all your help.
