Documentation #23

Closed faph closed 10 years ago

faph commented 10 years ago

I have started creating some documentation for the floodestimation library.

See http://floodestimation.readthedocs.org/

mikerspencer commented 10 years ago

What do we need to get a catchment descriptors generator?

Which days sets are missing? I'd like to push some doors and see if we can get/generate analogues.

Assuming "days sets" in your message means "data sets":

Let's start with QMED:

Long day, and working from phone with whisky...

Badc licence may be for nerc projects, I'll need to check. If so can correlate against new ceh gear dataset ( http://cehsciencenews.blogspot.co.uk/2014/09/developing-new-ceh-gear-dataset.html) and publish relationship. Perhaps worth doing anyway as would give users a greater choice of lta baseline.

Land use can certainly be taken from vector map. Again a straight forward traceback to gauge cds would show correlation.

Soils are OK in Scotland I think, harder south of the border.

I remember manually doing farl was a chore, but likely manageable.

I'll get cracking on finding, generating and verifying data. Python is not my bag, so I'll do what I'm good at.

  • Catchment area (use OS Terrain 50)
  • SAAR (can we get this through BADC?)
  • URBEXT (there must be land use data, e.g. Corine, OS VectorMap)
  • FARL (OS VectorMap)
  • BFIHOST (Soil data? Bit more tricky?)

Sounds good.

With this floodestimation library it's very straightforward to generate a sqlite db with all gauged catchments including locations and descriptors (it seems everybody is permitted to use this dataset for their own use). So if you start with that, we can do a comparison. Maybe we should start generating the catchment outlines as well for all gauging stations. If you fancy some GIS work, please do have a go. We probably should start a wiki page with each variable how this should be generated from various datasets in GIS. Do you do PostGIS?

Very randomly I've just been at the pub with Miguel Piedra discussing among other things a open source cds resource. Reckon we can get him involved. Topographic cds are easy, farl is a bit of a pain but I have a sql query som where that does it using a river network and lakes polygons. Saar can be replaced with an average annual rainfall grid from cru. Soils are impossible. Short duration rainfall is impossible. Propwet can be approximated from saar and pe.

"Very good" (quoting the famous MP).

If MM could do some research on what the soil options are? How far can we get in Scotland?

Time for an Open Hydrology meet up/christmas party?

mikerspencer commented 10 years ago

A gathering, good idea.

I'll pursue data, in amongst other projects. Ceh have offered me morecs, I'll need to check licencing, but I can verify an available data approach to pe and publish a tech note. Small steps.

Is that your email signature "Sent from my phone, apologies if there are any typos."? Why don't you get a real phone, one with keys?

mikerspencer commented 10 years ago

It is the signature on my phone. Thank you for your suggestion.

I've just set up an umbrella documentation site for all Open Hydrology stuff:
