The GSI releases useful digital map data, specially Digital Map 50 m Grid (Elevation) has high resolution and be used effectively in many area of industries and hobbies. But this product does not include Japanese Northern Territories elevation data (Japanese Northern Territories consist of 4 islands: Kunashiri, Etorofu, Habomai, and Shikotan islands. These islands are not included so called "Kuril Islands" in political meaning.).
By the way, there are raster image digital maps in GSI's products. We make MEM format files from contour data of "Digital Map 200000 (Map Image)" by hand. We sell it by online now.
Because we are making it completely by hand, there are following weak points in our MEM files comparing to original GSI's MEM file; we declare.
|1.||Accuracy of elevation data is around 100 m with averaging, because accuracy of a contour of original data is aroung 100 m.|
|2.||With averaging, resolution of elevation is 10 m, but it is worse than MEM files of GSI original (it is 1 m).|
|3.||Adjustment is done for avoiding stair shape with too less averaging, and for avoiding lose fineness with too much averaging.|
|4.||There are some parts with line or stair at the edge of MEM file, because of hand-made operation.|
|5.||The header of the file is mostly compatible to MEM file, but we do not guarantee complete operation of all software which utilizes MEM file.|
Watching photos is the easiest way to understand our product. For example, we use a famous 3D map engine KASHMIR 3D. First, please look whole 2D view of Northern territories. (Click to magnify.)
