UCalgary Space Remote Sensing Open Science Platform ​

Welcome to the UCalgary Space Remote Sensing (SRS) Open Science Platform. The open science platform facilitates collaborative research, data sharing, and knowledge dissemination by making scientific resources freely accessible to the public.

Open Data Archive

Browse our open data archive. The archive is accessible using a variety of methods, including HTTP, FTP, Rsync, Python libraries, IDL library, and direct API-based access. Learn more here.

Working with our data

We provide several libraries for working with our data, along with a vast example gallery. Tools are for Python and IDL, along with a RESTful API available for direct interaction.

FAQ ​

How do I properly acknowledge and cite the data I'm using?

Each dataset contains an acknowledgements file housed in the appropriate data tree. The file contains required data acknowledgements and/or the DOI for the dataset (e.g., REGO). You can also consult the list of datasets to find links to appropriate acknowledgements file. If you cannot find what you are looking for, please reach out (Emma Spanswick, Eric Donovan).

I think something is wrong, who do I contact about the data I'm using?

If you encounter issues or have questions about the data please reach out to the instrument contact listed on the Dataset Documentation page.

Can you change the operating mode of the senors to support my science?

Some UCalgary instrumentation has capacity for different operating modes. If you are interested in discussing operational modes, please reach out to the contact for the appropriate instrument type/network.

Are there any new sensors planned for the near future?

We are always looking for ways to improve the quality and information content of our data. This can be modifications to operational modes, calibration procedures, or designing next generation instrumentation. Currently, SMILE-ASI is in active development, with GDC-G following closely behind. If you are interested in learning more, please reach out the UCalgary team.

How do I get last night's full resolution data?

Depending on the instrument type, full resolution data may not be available in real-time. Higher data rate systems (e.g., ASIs) often rely on physical recovery of hard drives with a 3-6 month lag for data to be available. Our data archive is built on a philosophy of 'if we have it, you have it', so for our fully operational systems if you do not see full resolution data, it is very likely still in the field. For high-value data, and on request, we can sometimes retrieve portions of large datasets (e.g., an hour of data). If you have a specific data request please reach out to the instrument contact.
