ArcGIS release DEM local service

Article: This article is a problem encountered during the project, and then ask ESRI official blog, organize.
, With the original DEM are generally used in the course of the project in the CS program, or BS with online DEM can, due to the special nature of the project requires the use of high-precision DEM BS, online DEM progress is not enough, you can only publish local DEM, ESRI provides a tool but found no DEM issued a special service only publish images and maps of the service, I looked for information on the internet, Email official answer, given that the current version of the DEM to publish services through video services. (Version 10.4, there is no in-depth study estimated that subsequent versions is the same).
1, first of DEM data for publication. It's not easy to load and use the ArcMap release, but needs to be published to imageservice service, which requires arcgis image extended authorization server. Operates as follows, using ArcMap directory panel, corresponding to expand on DEM, right-click [] is shared as an image service, as shown below:
2, since the data is typically not not Mercator web, must be specified as a time release arcgisonline Microsoft bing, googleMap same projection (that is, web Mercator projection). As shown, the cache select options:

3, the use of this scheme, tiling scheme is fixed and can not be modified. If you want you can modify your own tiling scheme, you can choose to use the existing cache map [/ video] service programs, but here there is a premise that these programs must be Web Mercator coordinate system, and the cache must meet the requirements of the second point requirements. (If it is to define the way slices, each level must be the same scale online maps, or can not use, it is strongly recommended to use the online map cut way). But if you want to customize, you must follow the rules, that is, the proportion of primary cache must be twice the next level. For example, L0 is 1: 20,000, then L1 is 1: 10000, L2 is 1: 5000, 1 can not exist: 8000 This law does not scale, or when calling overlay will prompt caching rules is incorrect.
4, you must use the video service of the new rules LERC rules. Because it is web 3d, therefore, it can not be like the original two-dimensional image in the format of the picture, but with the new terrain slice manner. Below, is disposed inside the cache advanced settings.
