Since Digital Maps (Basic Geospatial Information) are basically provided online, they can offer new information on a daily basis as a result of surveys that reflect major changes to the land, compared to traditional survey results. However, it is necessary to use special software in order to utilize Digital Maps (Basic Geospatial Information) as map data. So the online publishing of 'Digital Topographic Map 25000' (hereinafter referred to as 'Digital Topographic Map') began on August 30 2012 so that map information that immediately reflects major changes to the land can be used more conveniently as a survey result in a raster image file format on a 1:25,000 scale level. Using this Digital Topographic Map, maps can be created that optimize the benefits of online publication by selecting the display range and size, as well as some display colors of map symbols and representations according to the intended use of the purchasers. Another feature is the ability to always provide the latest version of map images, as the images are generated from the Digital Japan Basic Map of Japan database as soon as the order is received from the purchaser, rather than from archived images. This paper presents the concept and specifications of the 'Digital Topographic Map' as the new survey result, and an overview of the content of the development of the system being provided.
