Abstract:	In this report we describe a digitizer developed in the laboratories of the Indian Institutes of Astrophysics (IIA) to digitize the large amount of solar synoptic data obtained since 1904 at Kodaikanal. We show a sample spectrum, an Hα Spectroheliogram, and a Ca+K spectroheliogram digitized using this equipment. The digitized data will be used to study the temporal variations in photospheric and chromospheric rotation rates, the solar differential rotation, the evolution of sunspots & Hα filaments, and in the evaluation of Ca+K plage and network indices. The digitized data will be made available to the scientific community as a part of IIA's astronomical data archive.
