The USGS has collected and released topographic data that show the erosional effects of the January 2023 storms on the coast for the Santa Cruz region of California.
These data were developed from photographs collected in partnership with Ecoscan Resource Data during the afternoon of January 5th, 2023. Photos have been processed with a digital technique called structure-from-motion photogrammetry to make accurate orthomosaics of the coastal landscape. Comparing the data with pre-storm conditions mapped in September 2022 provide “before” and “after” perspectives of the effects of the January storms. These data have been released under USGS Emergency Use Data authorities for data that have immediate or time-sensitive relevance to public health and safety.
Post-Storm Topographic Change Data
To explore the data, using a computer mouse is recommended.
• Tools: Pan (left mouse button), Zoom (mouse wheel or right mouse button), Spin orientation (press mouse wheel).
• For topography data, you can explore the data as elevation values or with the real-world colors captured by our cameras. To toggle between these, click on the Palette icon to open the “Colors” window and select either “elevation” or “RGB”.
• For topographic change data, ensure that “RGB” is selected in the “Colors” window, which is accessed from the Palette icon.
• The data can be presented along with other map and elevation products. These can be toggled by clicking the Globe icon and selecting from the different “Terrain” models and “Imagery” datasets, some of which have labels such as street names.
