Mapping Village Locations

vendredi 4 février 2011, par P. Ramirez

Mapping the distribution of names requires basic maps indicating village locations. Since these were not available, we had to create these maps ourselves. Various sources were used. Classic US AMS maps provide fairly good data on the terrain. Toponyms, however, are much less reliable : they originate from 1944 Survey of India data, and village names in this region are subject to frequent changes. Until the 1950s Karbi villages took the name of their headman. Government of Assam and Government of Meghalaya district maps are rather limited due to Indian regulations regarding the publication of large-scale maps. Approximately 100 village locations were found in the field using GPS readings. The remaining locations were obtained by combining AMS toponyms, approximate locations given by local villagers and Spot images (thanks to the ISIS programme run by the French Spatial Studies Centre, CNES). Spot images were studied both with the naked eyed and processed by MultiSpec software to obtain rough land cover maps. The following is a comparison of spatial data available from several maps. The zone shown here is the central part of our area of study.
