HI @lkilcher,
Can you please point me to the latest GIS-friendly download of these NREL datasets to characterize renewable energy potential in the report (at varying levels of constraints)?
Data | Source | Website |
---|---|---|
Tide | Georgia Tech Research Corporation | http://www1.eere.energy.gov/water/pdfs/1023527.pdf |
Wave | Electric Power Research Institute | http://www1.eere.energy.gov/water/pdfs/mappingandassessment.pdf |
Wind | AWS Truepower, LLC for windNavigator® | http://apps2.eere.energy.gov/wind/windexchange/windmaps/ |
The above links point to PDFs and not full downloads. Do you recommend the following NREL data sources for characterizing different marine renewable energy potentials?

Some of these tools point to more refined or alternate data sets.

This layer represents the annual average wind resource data used in the Renewable Electricity Futures Study (http://www.nrel.gov/analysis/re_futures)... Standard exclusions were applied to eliminate protected areas (wilderness, wildlife refuges, parks, etc.), incompatible land use (wetlands, urban areas), and other criteria from the available wind resource.

This never finished Loading for me
Also great to see WFS, WMS, TIMS, WMS-C and WMST OGC web services through NREL GeoServer.
@bbest I've inquired on why the MHK Atlas is not working. I'll let you know when it's fixed. I do have resource data for wave and tidal, but I'm hoping we can just grab it from the MHK Atlas when that is back online. Also, I'm not sure what you mean by 'GIS-friendly'. I assume this means public--at a minimum--but does it also mean: shapefile, or CSV, or SQL database of some kind, or ?
@pbeiter can confirm whether the OSW data listed above is the most up to date available.
@bbest
OK. The MHK Atlas is back online; sorry about that. You can download the wave data through that portal (click the down-arrow next to the layer).
The tidal data is too big to download through that interface, and I don't think it is currently publicly available anywhere else. I'll work on getting you a public link.
Great, thanks @lkilcher! The MHK Atlas looks good.

This link (http://en.openei.org/datasets/node/884)) however redirects to only to the generic catalog (http://en.openei.org/datasets/dataset), but is presumably meant to go to:
which is preferable in having data files over the duplicative pdf report only "dataset":
The shapefile download from here is the same as the table I previously listed from the NREL GIS - Marine & Hydrokinetic Data page:

Yes, by "GIS-friendly" I meant something mappable (shapefile, KML, CSV, geodatabase, etc) vs an image (without georeferencing or value attribute table) or pdf that are found elsewhere on NREL.
Yep, I see the disclaimer:
Annual Tidal Power Density Downloading the entire dataset through the map interface is not possible due to size restrictions.
Thanks for looking into downloadable, public version.

Hmmm... I don't have that problem on Chrome.

Where did you find the node/884 link?
Hi @lkilcher,
Super minor, but probably good and easy to fix. Here's how I got there:
In Data Layers, expand Marine & Hdyrokinetic Atlas > Wave Power Density > WEF Annual (one of the default layers checked on), and click on the "?" icon to the right of the layer, which gives you the following text:
Wave Power Density Wave power density is the calculated kilowatts per meter of wave crest width at any given water depth. Equation A-6 of Appendix A in the full report.
Source:The Wave Energy Resource Assessment project is a joint venture between NREL, EPRI, and Virginia Tech. EPRI is the prime contractor, Virginia Tech is responsible for development of the models and estimating the wave resource, and NREL serves as an independent validator and also develops the final GIS-based display of the data.

The link for the text Mapping and Assessment of the United States Ocean Wave Energy Resource is http://en.openei.org/datasets/node/884.
Hopefully that clears up this from previous...
Collect best available spatial data, similar to the U.S. west coast preliminary work:
Newer renewable energy datasets from NREL may be provided.
