Conventional Signs.

The milestones are numbered successively either from a town in the map or from the place named in the margin where the road leaves the map. Irrigation department bench-marks furnished by the executive engineer for irrigation thus ☉ B.M. 52.9, G.T. Survey spirit levels, thus ⊡ B.M. 123.45.

Heights above mean sea level determined trigonometrically represented, thus 100. Relative heights in feet mile-posts on the railways are numbered successively either from Bombay or from Miagam Railway Station. The linear values are derived from the measured length of the Sironj base assumed as log. feet 4.5844824, through the Karachi Longitudinal Series.
The latitudes from that of kalianpur, assumed as 24° 7' 11.2, through the karachi longitudinal series.
The longitudes are referrible to the old value of the madras observatory, 80° 17' 21, to which a correction of - 3' 1 is required to reduce to the most recent value, viz : 80° 14' 20, vide nautical almanac for the current year. The trigonometrical heights are referrible to mean sea level at Okha Tidal Station on the Gulf of Cutch. Index to the adjoining sheets |
