DelineateIt how to make outlet features?

Hi @ndmetherall,

@ndmetherall

Could I also ask if it would make any difference whether we download our SRTM / DEM data from the NASA platform in the course materials or from Earth Engine or should the results be the same regardless?

So long as the data meet the criteria needed for use in InVEST, where the data come from shouldn’t make a difference in how the model is running.

@ndmetherall

I tried again recently with the NASA SRTM DEM but it doesn’t seem to be able to recognise the data as being in the suitable format with linear units. Any advice about how to put it into linear units? I have tried multiple projections that are usually suited for linear units.

Using a UTM projection (looks like maybe zone 60s would be best for Fiji?) should work well except for Web Mercator. As for reprojecting itself, Stacie has a great post on another thread (How to deal with the error message "Dataset must be projected in linear units."？ - #2 by swolny) that you might find useful as well.

Please let us know how this goes!
