How the property locator works

1. From area to quadrant
In the calculator model used for MLOD, J-13 covers 40-50°E and 20-30°S: a 10° by 10° area. It is divided into nine named regions called quadrants, arranged in a 3 by 3 grid. Here “quadrant” is a naming convention; it does not mean one quarter.
| Alpha | Bravo | Charlie |
| Delta | Echo | Foxtrot |
| Gulf | Hotel | India |
2. Why 3⅓°, rather than 4°?
The supplied Lunar Embassy calculator source sets a quadrant dimension to 12,000 arcseconds. Since 3,600 arcseconds = 1°, this is 3⅓°. Three quadrants therefore span 10°. Three 4° quadrants would span 12°, so a 4° by 4° subdivision cannot fit the same equal 3 by 3 model. Older deeds show 4° references; their historical meaning remains unresolved. We use 3⅓° provisionally, without claiming the old documents have been explained.
3. How a property number becomes a location
Each quadrant has 22 columns west to east and 23 rows north to south: 506 geometric positions. Numbering runs across each row, then starts the next row south. Property = (row - 1) × 22 + column. Lot 196 = (9 - 1) × 22 + 20; Lot 197 uses column 21. Each parcel spans (3⅓° / 22) in longitude and (3⅓° / 23) in latitude. The original form accepts 1-500; our locator also limits lookup to that range, leaving positions 501-506 as theoretical grid cells.
4. Where Lots 196 and 197 fall
Bravo is the northern-middle quadrant: 43.333333-46.666667°E, 20-23.333333°S. Combined Lots 196 and 197 extend from 46.212121°E to 46.515152°E, and from 21.159420°S to 21.304348°S. Their centre is 21.231884°S, 46.363636°E. In this south/east region, row 9 and columns 20-21 identify the two adjoining cells.
5. Why the acreage differs
On a spherical Moon, area = R² × longitude span in radians × [sin(north latitude) - sin(south latitude)], with R = 1,737.4 km. Longitude narrows with latitude. This model gives about 37.64 km², or 9,301 acres, versus the advertised 3,555.16 acres combined. We show both figures; we do not move the boundaries to force agreement. The source also subdivides a property into 42 × 43 named “acre” cells; that label is not proof that every cell equals one physical acre.
6. How to read the interactive map
Terrain view: an owner-supplied ACT/LROC screenshot with manually traced outlines, approximate alignment and limited close-up detail. Property view: calculated coordinates and areas from the provisional grid. Settlement view: selectable architectural concept districts, not georeferenced buildings. The website locator currently covers J-13 Bravo only; it is not a full replacement for the original global calculator.
