ORIGINAL MAPS AND COORDINATE TABLES

What the boundary sources show

The historical fisheries schedules are now transcribed across every mapped zone. Detailed island coordinates and an approximate 2022 Ream outline add evidence that was previously inaccessible from the map.

Fisheries zones: every source schedule compared

The two original Prakas contain 424 coordinate pairs across 56 zone records: the 55 displayed fisheries zones and one community-fishery polygon withheld because its source geometry is invalid. All have been compared with their digitised outlines.

For 27 mapped zones, every printed point lies within 3 m of the displayed outer boundary. That establishes agreement at the listed points; it does not verify intermediate shoreline detail, interior exclusions or later legal changes.

Joining every list in printed order produces 24 self-crossing rings. These tables need interpretation alongside their source maps: a crossing in a literal reconstruction is not, by itself, evidence that the mapped or legal boundary is wrong. One schedule supplies only two points.

Two especially clear transcription problems remain in the source: the Daem Thkov community-fishery schedule prints an easting of 31,098; the Kep protection zone prints 323,116. Taken literally, these points lie approximately 278 km and 97 km from the displayed boundaries. The transcription preserves both values.

Koh Rong: ten included land parcels

The clearer 2018 ministry annex contains 180 coordinate rows. Its numbering reaches 181 but omits 177. Seven island headings contain ten separate land-boundary rings; every available coordinate is assigned once, and the reconstructed polygons are valid and do not overlap.

The map legend identifies the black outlines as included park forest land. They are not holes to subtract from the outer marine boundary. The straight-line reconstruction covers approximately 5,452.44 ha in the source coordinate plane, compared with the instrument’s 5,361-ha land total. Shoreline detail and subsequent changes remain necessary to establish a complete net boundary.

This corrects the earlier description of “181 internal points”. No coordinate was invented for the absent number.

The annex for the 2023 Sub-decree 48 land change remains unavailable in the retrieved copies. Its effect has not been incorporated in these historical polygons.

Ream: the 2022 marine outline can be studied

An approximate historical outline has been recovered from the map attached to Sub-decree 10 of 10 January 2022, using its printed UTM 48N / WGS 1984 grid. The trace encloses about 39,428 ha, within 0.52% of the decree’s stated 39,634 ha.

The source image represents roughly 29 m per pixel. The tracing uses a conservative working tolerance of 250 m; this is a map-reading allowance, not certified positional accuracy. Agreement in area does not prove agreement at every boundary location. The trace is available for historical comparison and has not replaced the atlas outline.

Precisely which annexes are missing?

The parcel coordinates in No. 241/2023 are present, but not yet fully transcribed. They describe development parcels, not the entire park boundary. They must not be counted as unavailable material.

Record-by-record comparison

“Straight-line area” joins the printed points in their listed order. Areas are omitted for crossing or incomplete rings. “Largest point offset” measures the furthest printed point from the atlas’s outer boundary; it is not a survey-accuracy estimate. The original source area is included beside each zone name.

What still needs an authoritative answer

The reconstructed files preserve the historical sources. Current consolidated boundaries still need later amendments, signed corrections to conflicting schedules, and complete treatment of coastlines and land exclusions. Botum Sakor and Peam Krasop retain the specific 2023 layer discrepancies described in the earlier comparison.
