Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Topography, bmi-topography Model type Tool Model part of larger framework Note on status model Date note status model Incorporated models or components: Spatial dimensions 2D Spatial extent Global, Continental, Regional-Scale, Landscape-Scale, Watershed-Scale Model domain Terrestrial, Hydrology, Coastal, Marine, Geodynamic, Climate, Ecosystems, Cryosphere, Human dimensions One-line model description A CSDMS data component used to fetch and cache NASA Shuttle Radar Topography Mission (SRTM) and JAXA Advanced Land Observing Satellite (ALOS) land elevation data using the OpenTopography REST API. Extended model description Topography is a Python library to fetch and cache NASA Shuttle Radar Topography Mission (SRTM) and JAXA Advanced Land Observing Satellite (ALOS) land elevation data using the OpenTopography REST API. The Topography library provides access to the following global raster datasets: SRTM GL3 (90m) SRTM GL1 (30m) SRTM GL1 (30m, Ellipsoidal) ALOS World 3D (30m) ALOS World 3D (30m, Ellipsoidal) Global Bathymetry SRTM15+ V2.1 NASADEM Global DEM Copernicus Global DSM 30m Copernicus Global DSM 90m The library includes an API and CLI that accept the dataset type, a latitude-longitude bounding box, and the output file format. Data are downloaded from OpenTopography and cached locally. The cache is checked before downloading new data. Data from a cached file can optionally be loaded into an xarray DataArray using the experimental open_rasterio method.

Yes If above answer is no, provide end year model development Code development status Active When did you indicate the 'code development status'? 2021 Model availability As code Source code availability (Or provide future intension) Through web repository Source web address https://github.com/csdms/bmi-topography Source csdms web address Program license type BSD or MIT X11 Program license type other Memory requirements Data are downloaded directly to a file, so memory use is minimal. Optionally, the data can be loaded into a Python session, in which case, memory use scales with the size of the data.

Introduction

For more information on bmi-topography, including installation instructions and examples, see the documentation: https://bmi-topography.readthedocs.io. View the source code at https://github.com/csdms/bmi-topography.

Run on EarthscapeHub

bmi-topography is installed on EarthscapeHub, a set of JupyterHub instances managed by CSDMS.

Click this button:

Run on EarthscapeHub

to launch the bmi-topography Jupyter notebook tutorials on the EarthscapeHub jupyter instance.

Note

There are two conditions on running the bmi-topography notebooks:

1. Access to the EarthscapeHub jupyter instance is controlled through GitHub credentials. If you don't already have access to jupyter, please see these instructions on how to to sign up and sign in.
2. Once you've signed in to jupyter, be sure to select the "CSDMS" kernel from the JupyterLab kernel picker in order to run the notebooks.

If you encounter any problems using EarthscapeHub, please contact us through the CSDMS Help Desk.
