The projection from spheroid to a UTM zone is some parameterization of the transverse Mercator projection. The parameters vary by nation or region or mapping system. Most zones in UTM span 6 degrees of longitude, and each has a designated central meridian. The scale factor at the central meridian is specified to be 0.9996 of true scale for most ...
The territorial waters of Bangladesh extend 12 nautical miles (22 km), and the exclusive economic zone of the country is 200 nautical miles (370 km). Roughly 80% of the landmass is made up of fertile alluvial lowland called the Bangladesh Plain. The plain is part of the larger Plain of Bengal, which is sometimes called the Lower Gangetic Plain.
Bangladesh is divided into 8 divisions (bibhag) and 64 districts (jela, zila, zela), although, these have only a limited role in public policy.For the purposes of local government, the country is divided into upazilas (sub-districts), "municipalities" or town councils (pourashova), city corporations (i.e. metropolitan municipal corporations) and union councils (i.e. rural councils).
For example, in UTM, the origin of each northern zone is a point on the equator 500 km west of the central meridian of the zone (the edge of the zone itself is just under 400 km to the west). This has the desirable effect of making all coordinates within the zone positive values, being east and north of the origin.
If present, a dagger (†) indicates the usage of a nautical time zone letter outside of the standard geographic definition of that time zone. Some zones that are north/south of each other in the mid-Pacific differ by 24 hours in time – they have the same time of day but dates that are one day apart. The two extreme time zones on Earth (both ...
The intersection of a UTM zone and a latitude band is (normally) a 6° × 8° polygon called a grid zone, whose designation in MGRS is formed by the zone number (one or two digits – the number for zones 1 to 9 is just a single digit, according to the example in DMA TM 8358.1, Section 3-2, [1] Figure 7), followed by the latitude band letter ...

The urban centers of Bangladesh have a combined area of about 10600 square kilometers, which is 7% of the total area of Bangladesh. As such, Bangladesh has a very high urban population density: 4028 persons per square kilometer (2011), whereas the rural density is significantly lower: 790 persons per square kilometer (2011). [1]
