Hi, Depth rasters are needed as input to the flood impact analysis solution. At the moment you can not create depth rasters in the solution. Regards Gert

Hi, All these models are in the Living Atlas. There is a link in the 3D basemaps task. https://www.esri.com/arcgis-blog/products/arcgis/imagery/introducing-ready-to-use-deep-learning-models/ https://livingatlas.arcgis.com/en/browse/?q=type:%20deep%20learning%20package#d=3&q=type%3A%20deep%20learning%20package&type=tool Cheers Gert

Hi Amanda, I tested with your data and it seems releated to using the 'memory' workspace. There are a couple of things you can do: reduce the size and resolution of the input raster. You can tile the input raster into subtiles and run the tool on the subtiles. write to disk instead of memory. We will provide an update to the solution so that this tool writes intermediate data to disk instead of memory. In the meantime you can enable this yourself by modifying the Python script: Go to the scripts folder inside the flood impact analysis solution Open the ‘create_3Dflood_level.py' in a text editor Search for the line ’in_memory_switch = True’ in the ‘run’ function Changes this line to ‘in_memory_switch = False’ Save the file Start ArcGIS Pro. Run the tool.

The 3D basemaps solution can be used by mapping technicians to create and maintain a 3D basemap for their organization, leveraging existing data such as lidar, building footprints, meshes and underground utility features. The February 2021 release of the 3D basemaps solution has some great enhancements: Mesh support: besides publishing and modifying meshes using standard Pro tools, this solution release also allows you to modify existing web scenes reducing the need to republish a mesh from Pro after every modification: Besides the new mesh support, we also added: ability to color trees in lidar point clouds. By popular demand, we have added a workflow to colorize tree points in your lidar using aerial imagery. This is a great way to visualize vegetation in your scene without having to extract tree features. For more information, check out the "Getting to know 3D basemaps" storymap or visit the ArcGIS Solutions website.

Hi Raul, I had a look at your data. The problem I think is that there are not enough ground points in this dataset so that ArcGIS can create a proper dtm. Also it seems a number of points are misclassified as ground because they seem part of a roof? Gert

Hi, the link is changed but Geonet is not updating. For now, you can use: https://www.arcgis.com/home/item.html?id=58d77b24469d4f30b5f68973deb65599 Thanks.

The November 2020 solution release sees the first integration of deep learning into the 3D basemaps solution. Leveraging a new tree classification deep learning model on the Living Atlas, it is now possible to classify trees in lidar point clouds in ArcGIS Pro. Before and after using deep learning to classify trees in the lidar point cloud This solution release also adds a new density based cluster approach to tree extraction which significantly improves the tree extraction compared to a raster based approach. Extracting tree location, height and width using density based clustering. Just keep in mind that density based clustering on large amount of points is much more resource intensive than the existing raster based approach so we recommend using the latter first to get a generic tree coverage and use the density based cluster approach only for areas where you need accurate tree extraction. For more information, see the 3D basemap solution documentation.

Hi Didem, You need as input: depth raster and dtm the solution allows you to create a water surface elevation raster from depth raster and dtm OR... water surface elevation and dtm simply subtract the dtm from the water surface elevation raster to get the depth raster So this solution does not create a depth raster and water surface elevation raster. It can only derive 1 or the other if you have the dtm as well. It is possible to calculate a depth raster using the ArcHydro tools. See this link for more info. Arc Hydro for ArcGIS Pro Does that makes sense? Gert

Hi Didem, The solution does not create depth rasters. These are required as input and are typically created through hydrologic modeling. Once you have proper flood depth rasters, you can use the solution to analyze impact on assets. Regards Gert

Hi, I haven't done this myself but if I understand it correctly, the con tool will give you the HAND raster area that is flooded at a certain chosen flood event depth. This still is not a depth raster. You would need to subtract the result raster from the chosen flood event depth value to get a depth raster. Maximum depth is where HAND == 0. Depth 0 is where HAND == chosen flood event depth. But please keep in mind that -> "using a single flood depth for all streams in your study area might not be realistic as each stream segment or reaches within a stream segment could flood with a different depth. The accuracy of your results will also depend on how the surface raster is hydro-conditioned, how the surface raster aligns with stream data, and flood depth data that you are using, among other factors."

Hi Trevor, The solution does not do any flood modelling. It allows you to calculate the impact of various flooding events on different assets (such as buildings, bridges, roads). A HAND raster is basically a normalized DTM. It is not a depth raster which you get after flood modeling. A depth raster is a raster that describes the depth of flooding at each raster cell. You need 1 or more (1 for each flooding event) depth rasters to run the flood impact analysis. Once you have depth rasters, make sure you use the latest release of the solution: Flood Impact Analysis | ArcGIS Solutions for Local Government Let me know if this make sense. Gert
