<u>[https://scalgo.com/en-US/live-flood-risk SCALGO Live]</u> is a cloud-based terrain analysis tool which provides an interactive assessment of topographic changes on the potential flood risk. Topography, and user-defined modifications, can be exported in a range of formats which can then be utilised within TUFLOW as the DTM dataset.
SCALGO Live also supports importing, visualizing, and sharing results from hydrodynamic model simulations, including time-series data, through hydrodynamic modelspaces. This allows the user to visualise TUFLOW results in SCALGO Live. Both of these options are described in the below sections.

= Exporting Terrain Data from SCALGO Live for use in TUFLOW =
SCALGO Live contains extensive elevation datasets which although openly available from other sources, can be easily exported from SCALGO Live for use within TUFLOW. As well as elevation datasets, there are also landcover, soils and mapping datasets which can be obtained. The datasets are country specific so may vary depending on your SCALGO Live subscription. <Br>

*Once created, it is possible to use the existing elevation datasets or to make additional edits. See the [https://scalgo.com/en-US/scalgo-live-documentation/workspaces/editing SCALGO Live Editing Topic] for more information.<Br>
*With any edits having been made, choose the Export Menu on the toolbar at the top of the workspace and choose to

Choose the desired resolution, output format and projection. For elevation data, the data can be downloaded as a ''Geotiff'', ''ENVI .hdr labelled raster'', ''ERDAS Imagine (img)'', ''Arc/Info (aka ESRI) ASCII Grid (.asc)'' and ''ASCII Gridded XYX''. Currently TUFLOW only supports the ''Arc/Info (aka ESRI) ASCII Grid (.asc)'' format. The 2023 version of TUFLOW will support Geotiffs such as those from SCALGO Live. Other formats can be converted using the approaches outlined [[Raster_Format_Conversion_Using_gdal_translate| here]]. <Br>
For vector datasets, these can be downloaded as a ''Geopackage (gpkg)'', ''Shapefile (shp)'', ''GeoJSON (geojson)'', ''MapInfo Tab (tab)'' and ''DXF (dxf)'' format. Currently TUFLOW supports shapefiles but will support

= Importing TUFLOW Results in SCALGO Live=
SCALGO Live also supports importing, visualizing, and sharing results from hydrodynamic model simulations, including time-series data, through hydrodynamic modelspaces.
*With SCALGO LIVE open, within the '''Library''', select '''ModelSpaces''' and

*The import can then take a few moments with a progress bar reporting progress. Once the import is complete, it’s possible to select the relevant TUFLOW Results dataset and display within the SCALGO Live interface.<Br>

It is possible to add results from multiple events/scenarios to the one modelspace.
A summary of the tools within SCALGO Live for analysing modelspaces can be found at the following <u>[https://scalgo.com/en-US/scalgo-live-documentation/modelspaces/intro page]</u>
