Web Data Scrapers

On a nightly basis, scheduled tasks are used to automatically download and insert new data into the ORMGP database, a process called “web scraping”. So, in addition to hydrogeologic information, the database maintains a realtime hydrometeorological dataset at the daily time scale.

Groundwater monitoring

Groundwater monitoring data, like those collected by the ORMGP, are kept in their time-scale, typically in the order of 10 min to hours, and inserted into the database.

Climate data and Streamflow

For the most part, information scraped below do not enter the database as they are sub-daily resolution. Rather, the higher-resolution data, including the gridded data, are maintained running Delft-FEWS.

The objective is to maintain a daily hydrometeorological dataset spatially distributed over the 30,000km² ORMGP management area, going back at least a century. Data collected are “near” realtime in that they are what is reported when the scheduled task was run (the night prior). The web tools we maintain and numerical models we archive depend on this dataset.

Current data sources

Below is a list data sources used in deriving many of the interpolation products. These sources are all free and open, but come in a variety of formats.
