Project Member Reported by chris.fl...@gmail.com, May 27, 2012 From Kristen Williams:

Hi Lee,

Here’s the LF7RUP datasets. It is a categorical dataset. I’ve included this as a float grid which is the format required by GDM. However, GDM doesn’t work with categorical data – only continuous and ordinal…I don’t use this in GDM modelling, but it may be effective in Maxent modelling. This is the 0.01 grid version. I’m still working on the 250m grid data.

As in all the data I provide, the coastline of the 1km grid has been expanded a few cells to ensure full coverage and nodata cells have been filled to ensure consistency in data/nodata and modelling extent (a requirement for GDM analysis).

The custodian is ANU, but Brenda Mackey was the contact – Brendan is now based with Griffith at the Gold Coast.

I haven’t yet generated metadata also for this version of the layer, and will put that task on my to-do list.

Cheers,

Kristen

Are we still interested in this layer and is it priority critical?

Cheers, Chris Jun 6, 2013 Project Member #3 leebel...@gmail.com Let's lower the priority until we hear about any requests for it. Topographic position will certainly be more relevant at the 250m grid that 1km (0.01 degree) - particularly for vegetation where this data can highly influence the species composition.

Labels: -Priority-Medium Priority-Low Jul 11, 2013 Project Member #6 leebel...@gmail.com Kristen: I assume the categories are something like 'ridge', 'upper slope','mid-slope', 'lower slope' and 'valley'? Certainly could be useful in Sampling, MaxEnt and tabulation.

This dataset would only be of use at the 250m resolution (and with metadata :))

Needs metadata.

Hover value and use in analysis will return the numerical value. Legend image has both the label and the numerical value.

Is it useful to use this layer as an environmental? Does it need to be flagged as a contextual when run in maxent? I can try to change it to a contextual if that is more appropriate.
