We have followed during the two latest articles ( The Spatial-Temporal Cube<\/a> of ArcGis : 1- discovery<\/a> , The spatial-temporal cube<\/a> of ArcGis : 2 hot spots and cold spots<\/a> ), an\nexample for the building and visualization of a spatial-temporal cube with\nArcGis Pro 1.0.
\nWe will discuss here how to do the same without ArcGis Pro, but using ArcMap\nand ArcScene 10.3.
\nTo answer the question asked in the title, is it possible or not, we will answer\naffirmatively , but at what price?
\nAs for the first part , building the cube, it is possible with ArcMap.
\nThe 3D visualization of the cube, even if this is not documented in the ESRI\ndocumentation, it is possible with ArcScene.
\nLet’s take a look at all the obstacles to overcome , because it’s an obstacle race!\n

Building the cube with ArcMap<\/strong> \n\nWe resume using the two previous articles data,\nthe winds forecast for Brittany.\n\n\n\n<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

The two fields we are going to use are Gust ( bursts ) and DateTime\n(date field). <\/p>\n\n\n\n

Firstly, let’s consider what should be done (for the time being ). \n\nTo create the cube, which will be stored in\nNetCDF format ( .nc ), we will use the tool Create<\/strong>a<\/strong>space-time<\/strong>cube<\/em><\/strong>from the Tools<\/em><\/strong>models<\/em><\/strong>exploration<\/em><\/strong>spatio-temporal<\/em><\/strong>  toolbox.
\nThe Toolbox is available in the ArcMap Toolbox , and everything suggests that\nyou can execute it .\n\n\n\n<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

\nWe launch the tool and the settings window opens :    \n\n<\/p>\n\n\n\n

<\/p>\n\n\n

For the first three fields, no problem : data Input, output cube, input\ndate field data. <\/p>\n\n\n\n

Where it starts to get tricky is when you have to inform the temporal\ntime step and the geographical time step . \n\nWhen you click the Interval temporal window help\nyou get the following :  \n\n\n\n<\/p>\n\n\n

You can follow the instructions and type 2 days , 4 weeks … nothing\nwill work because the order was not designed to speak english ! If you want to execute\nthe command, you will have to type 12 Hours, 1 Day , … <\/p>\n\n\n\n

With this discovery , you could think that it would work as well with\nthe distance interval . Well, yes (or almost) , since the field for the units\nof distance ( meters , kilometers , …) is not modifiable! So not possible to\nenter them in English or any other language. Since the field is not mandatory ,\nwe\u2019ll leave it blank and the command will calculate it by default. <\/p>\n\n\n\n

Viewing<\/strong> 2D<\/strong> results<\/strong> <\/p>\n\n\n\n

We have discussed how to load a complementary toolbox with ArcGIS Pro:\nto visualize the cube you must Download a Toolkit containing two tools, one to\nvisualize the cube in 2D and another to visualize the cube in 3D.
\nThe Toolbox can be downloaded at http:\/\/esriurl.com\/SpaceTimeCubeUtilities<\/a> .
\nThe 2D command should work for ArcMap and the 3D command for ArcScene. They\n\u00ab\u00a0work\u201d since they run without error , read the file netcdf, load the resulting\nlayer in ArcMap and ArcScene, except that symbology is not taken into account .\nIf you look at the scripts, the layers are of. Lyrx type and not .lyr. The\nextension . lyrx is specific to ArcGIS Pro and is not compatible with ArcMap\nand ArcScene. <\/p>\n\n\n\n

To display the cube in 2D with ArcMap, you can copy the script with a\nnew name and replace the called layers ( directory spacetimecubeutilities \/\nscripts \/ templates) by those present in the ArcGis \/ Desktop10.3 \/ ArcToolbox\n\/ Templates \/ Layers installation directory , for example the Emerging_All.lyrx\nlayer by Emerging_All.lyr . <\/p>\n\n\n\n

Regarding the 3D visualization with ArcScene, here is the procedure to get\nthe same as with the ArcGis Pro Scene : <\/p>\n\n\n\n
