Water Flow: The terrain topography determines how surface water is transported to the ocean. Explore how water flows on the surface and forms flow networks, interactively choosing network detail.Show Water Flow
Sea-Level Rise: The terrain contains barriers to rising sea water, once water rises above these barriers there is a risk of flooding. Interactively select any possible sea level rise and see the effects.Raise Sea Level
Watersheds: A point on the terrain surface can potentially receive surface water from a very large upstream area. Interactively visualize the extent of the upstream area of any point.Inspect Watersheds
Combine: Customize your map with flow networks at desired detail, flooding from a given sea level rise, and combine with watersheds, topography, as well as street and place names.Combine Layers
The surface of the Earth is our natural habitat. Its topography determines many things about our lives; where rivers form and where the sun shines, it decides what we can see and the routes we travel along. At SCALGO we work on analyzing huge digital representations of the Earth's surface — below and above sea level. We seek to extract information that can inform decision making processes and improve the understanding of our habitat. We do so by building on advanced algorithm technology, initially developed within leading US and European research institutions, and further developed and commercialized within SCALGO.
We work closely with scientists, data providers and end users to develop groundbreaking analysis methods, and state-of-the-art algorithms that allow these methods to be applied on a regional, national or even global scale. SCALGO Live Global is our way of sharing global analysis with the community and the general public. This first version focuses very much on water flow and flood risk. Depending on feedback, we will be continuously adding new analysis and new innovative tools to SCALGO Live Global. This is made possible by the near-global digital elevation model SRTM, which is made freely available by NASA, as well as the hydrological modifications performed in the HydroSHEDS project by the WWF. The resolution of these data sets is three arc-seconds, or 90 meter at the equator. SCALGO also does a large range of commercial projects on high resolution (submeter) digital elevation models, even for very large areas (e.g. national scale). These enable a more detailed and precise analysis. Contact us or visit scalgo.com to learn more about SCALGO Live or our other products.
Since the models have a resolution of 90 meter at the equator, geographic objects with a surface extent smaller than 90 m might not be captured in the data. This of course adversely influences the result of any analysis performed on the data, especially flood risk analysis since dikes and dams may not be captured in the model. This should be considered before applying the analysis results available on SCALGO Live Global. SCALGO cannot be held accountable for any damages that might occur as a result of using the analysis available on SCALGO Live Global.hide
