An implementation method of map projection and a sharing function are investigated for realizing a visualization tool suitable for huge numerical simulation data of planetary atmospheres by the use of Web Map Tile Service (WMTS). Because a combination use of multiple WMTS-compatible web map libraries is effective to achieve map projections, the multiple libraries are used together by using a computer programming technique called wrapping. To implement the sharing function, we extend a method of "Drag-and-Drop map" (https://gsj-seamless.jp/labs/ddmap/). Our tests confirm that operations such as switching between map projections including a projection onto a three-dimensional sphere are easily realized in a Web browser. In addition, our tests also confirm that the information necessary for visualization of numerical simulation data, such as contour or tone diagrams, map projection method, geophysical quantities to be displayed, magnification rate, and so on, can be shared among collaborators in the form of a JSON file or a URL of websites that publish HTML elements.
