Source identity and administrative path
The source row behind Omdurman is GeoNames ID 365137. Its recorded administrative path is Khartoum → Sudan, and GeoNames classifies the place as a populated place. Omdurman occurs once as a primary city label in this atlas sample; the numeric ID remains the durable source key if names change. The city row itself was updated 2025-10-12; that date belongs to the source record, not to every transport or visitor detail in the real destination.
Population position inside fixed cohorts
Within the fixed 1,206-record atlas, Omdurman ranks 230 by recorded population. Inside the 5 selected Sudan entries it ranks 2; inside the 243 entries in its broad region it ranks 51. Its 1,849,659 population value is 1.83 times the 1,012,211 median for the country cohort and 2.05 times the 902,588 regional median. Omdurman is rank 2 among the 5 selected Sudan entries, so a percentage band would overstate this small cohort. Omdurman's recorded value is above the country-cohort median but remains below twice that benchmark. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Nearest-reference pattern
Omdurman's three nearest other atlas coordinates are Khartoum North at 6.11 km with 1,012,211 recorded people; Khartoum at 11.861 km with 1,974,647 recorded people; Port Sudan at 668.722 km with 489,725 recorded people. The closest-to-farthest distance spread is 662.612 km. Compared with Khartoum North, Omdurman's recorded population is 1.83 times as large. Against Omdurman, Khartoum North follows Khartoum → Sudan in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Sudan cohort, uses the shared Africa/Khartoum identifier, and carries the same populated place class. Its recorded population is below Omdurman's. Against Omdurman, Khartoum follows Khartoum → Sudan in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Sudan cohort, uses the shared Africa/Khartoum identifier, and carries capital of a political entity rather than populated place. Its recorded population is above Omdurman's. Against Omdurman, Port Sudan follows Red Sea → Sudan in the source. Its point has higher latitude and higher longitude; it belongs to the same selected Sudan cohort, uses the shared Africa/Khartoum identifier, and carries first-order administrative seat rather than populated place. Its recorded population is below Omdurman's. Its nearest-neighbor distance ranks 79 of 1,206 from shortest to longest in the same snapshot. Omdurman's nearest-coordinate gap belongs to the tightest tenth of the atlas. This pattern can reveal whether other catalog references are geographically close, but it cannot establish whether a border crossing is possible or practical, or whether rail, road, fare, or journey-time connections exist. Read as one record signature, GeoNames 365137, the coordinate pair 15.6445 / 32.4777, country rank 2 of 5, and neighbor GeoNames 379251 at 6.11 km bind Omdurman to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Coordinate, time-zone and class cohorts
Omdurman's reference point is 15.6445° north and 32.4777° east. The IANA identifier Africa/Khartoum is shared by 5 city rows in this catalog, while the GeoNames class PPL is shared by 243 rows. Omdurman's row carries a first-order administrative label but no second-order label. Omdurman's point falls in the lower-latitude coordinate band used by this atlas's row checks. Omdurman's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Omdurman, so the profile preserves that missing value instead of guessing terrain. Together these fields form a reproducible identity check for this page, not a claim about walkability, climate or accessibility.
