Hello, I have a DEM in ESRI Grid format. I was wondering if there is anyway to convert it to .obj or .3ds format for use in 3D modelling software? Thanks for any help.

How about convert Contours to Points. Use the point elevations to create a TIN. Convert TIN to DEM. Using DEM to create new contours.

Hi Mark, Here is an example on how to do this using the arcpy.da.UpdateCursor (10.1 or beyond is required): import arcpy from arcpy import env env.workspace = r"C:\temp\python\test.gdb" fc = "featureClass" with arcpy.da.UpdateCursor(fc, ["field1", "field2"]) as cursor: for row in cursor: if row[0] == 1: row[1] = 'Woodland' if row[0] == 2: row[1] = 'Arable' ...... ..... cursor.updateRow(row) del cursor, row Thankyou very much that worked a treat 🙂

Hello, I have a big dataset with a field of values ranging from 1 to 10. I want to update another field with a string depending on which value is in the other field. So for example: 1 = Woodland 2 = Arable 3 = River, etc etc I was wondering how I would go about this in arcgis? I have done something similar with SQL using an IIF function but am struggling with how to figure it out. Thanks for any help

Great thanks for your help in this 🙂

Hello Carrie. I think I've figured out what the issue might be but I'd like to verfiy with you first. One of the TINs used to create a multipatch is from a DEM. The other TIN is a surface created using interpolation to map depths of soil from survey points. What I have noticed is because part of the TIN is on a hill the soil depth layer actually extends out beyound part of the hill to there is some cross over between the TINs. I'm thinking it might be this crossover that is causing the issue?

Hello Carrie, I've used the information from the ESRI 'Creating 3D Data Using ArcGIS' tutorial. I followed this tutorial through then repeated it using my own data. I used the 'Is Closed 3D' tool and you are right the multipatch was not closed. I then used the 'Enclose Multipatch' tool but something seems to have gone wrong somewhere! The enclosed multipatch is several times deeper than my original multipatch. I'm attached some images so you can see what i mean.

Thanks Carrie. I've used the 'Add Z Information' tool on the multipatch. I get results for: Z_MIN Z_MAX Z_MEAN SAREA But get the following results for the other attribute fields Volume = 0 Min_Slope = 0 Max_Slope = <Null> Avg_Slope = <Null>

Could you not split the tile layer into individual tiles then do a batch process using extract by mask?

Hello Carrie. Thanks for getting back to me on this. I created a multipatch after extruding between two TINs which I have converted from DEMS. I just checked the attribute fields of the multipatch and I have the following fields: OBJECTID_1 * Shape * OBJECTID ID gridcode Shape_Leng There's no volume attribute field unfortunately. Any idea why? Thanks for you help! 🙂

I've been playing around with the 'Extrude Between' tool in the 3D analyst extension creating 3D models of layers of geology. I want to create a layer between the last geological layer and a DEM off the surface. Because I have to use TINs for the 'Extrude Between' tool I'm losing some of the detail from the DEM. I was wondering if there is a way to create a 3D model using raster images? So my idea would be to interpolate the geology depth to create a raster surface of depth and then extrude between this and the DEM surface.

I have a question regarding the 'Extrude Between' tool. I have created a multipatch object showing a 3D layer of geology after working through one of ESRI's tutorials. What I am wondering now is how you would go about calculating the volume of the multipatch that has been created so I can get some sort of measurment of the volume of material in the multipatch? Thanks for any help

Thanks Hornbydd. I've just been looking at applying a Maximum focal filter over say a 50m area and then subtracting this from the DEM. These seems to give an indication of the depth of material removed from the landscape. I'll definitely give your suggestion a go and see what I can come up with.

Also, Is it possible to export a layer as a kmz. file which seems to be much easier to work with in google pro rather than a shape file? In the mean time check out the following tools. They should do what you want. Layer to KML Map to KML You can use the seach window to find them.
