Walking the Dotted Line: Mapping Borders Before the Nation
Indian surveyors walked the territories they mapped, armed with precise strides and bamboo rods. Astronomers measured locations in the sky and on land. Seafarers plotted rhumb lines between ports and along coasts. But few marked political boundaries on their maps. This second lecture explores what it meant when such boundaries began to appear in Indian cartography. Do pioneering mapmaker Sadanand’s dotted lines in 1780 mark a moment when mapping became newly legal, administrative, and extractive?
