WELCOME to the "Old Survey of India Maps" Collection

The "Map Selection and Download Spreadsheet" below can be downloaded to provide an easy-to-use tool to view the file names of all the maps available on this website. Each of the filenames in the spreadsheet is a link to the map file, and a click on the file name will download the map to the viewers computer. This file can be stored by the viewer for future use, or an updated file can be obtained periodically from this website. The file is issued in an MS Excel format, but it can be opened by Google Sheets or other spreadsheet software. The map collection is broken down into 20 different categories based on topic, scale and geographic area. A tab at the bottom of the spreadsheet opens the page for each category.以下「地图选择与下载电子表格」可供下载，作为一款便捷工具，用于查看本网站所有可用地图的文件名。电子表格中的每个文件名均为对应地图文件的链接，点击文件名即可将地图下载至使用者的本地计算机。使用者可将该文件留存以备后续使用，也可定期从本网站获取更新版本。该文件以微软Excel（MS Excel）格式发布，同时也可通过谷歌表格（Google Sheets）或其他电子表格软件打开。 本地图集按照主题、比例尺与地理区域划分为20个不同类别，电子表格底部的标签页可跳转至每个类别的对应页面。
