Climate and satellite time-series tools

Choose a place or draw an area, pick a dataset and a period, and the service builds a chart or time-lapse from open climate and satellite archives. Results include the underlying data as CSV and can be reused with the credit shown. See the methodology and licences or browse the gallery of examples.

    Datasets, licences and limits

    The limits keep the shared service responsive for everyone; the form checks them as you go and suggests a coarser setting when a request is too large. Licences were checked on each provider's own pages on 27 October 2026.

    How the service works

    Requests join a single queue and run one at a time on our own server, so the page shows your position, an estimated start and finish time, the current stage and a progress bar. If the server is busy with other work, the queue pauses briefly to protect performance and resumes automatically. You can cancel a queued or running job at any time, and identical requests made recently are returned straight away from the stored results.

    Each output carries the line "Generated at TechnicalGIS.com" together with the dataset's required credit. You may reuse the outputs, including commercially, provided both are kept; the output terms give the details. Results are kept for 7 days.

    For larger areas, longer periods, finer resolutions, other datasets or scheduled updates, request bespoke processing.

    Frequently asked questions

    Is the climate time-series tool free to use?

    Yes. Each visitor can run up to 15 requests a day, one at a time, within the limits shown for each dataset. Outputs may be reused, including commercially, provided the "Generated at TechnicalGIS.com" line and the dataset credit are kept.

    How long does a request take?

    Most charts finish in 10 to 30 seconds and most satellite time-lapses in 30 to 80 seconds once they start. Requests run one at a time in a queue, and the page shows your position, an estimated start and finish time, and the current stage. Every job is stopped after 90 seconds of processing.

    Can I close the page while my job runs?

    Yes. The job carries on in the queue. Copy the job link, or return to this page in the same browser, to see the progress and download the results, which are kept for 7 days.

    What if I need a larger area, a longer period or a finer resolution?

    The interactive limits keep the shared service responsive. For larger areas, more frames, other datasets or regular updates, use the "Request bespoke processing" link, which pre-fills the contact form with your request.

    Where does the data come from?

    ERA5 reanalysis from the Copernicus Climate Change Service, CHIRPS rainfall from the Climate Hazards Center at UC Santa Barbara, Copernicus Sentinel-2 and USGS Landsat imagery, and NASA MODIS vegetation indices. Each dataset is read directly from its open cloud archive, and each was offered only after its licence was confirmed to permit commercial reuse of derived outputs.
