REA Data Portal 

The REA Data Portal is a one-stop source for geospatial data, maps, and models produced by BLM’s Rapid Ecoregional Assessments (REAs).  You can access these products through the catalogs listed below.  You can also download REA reports to learn about the key components of each REA such as the management questions, conservation elements, and change agents.

There are hundreds of data sets and dozens of maps available for each REA so we strongly suggest reviewing the report before using the catalogs.  We also recommend saving a local copy of each catalog for easier reference and downloading.

Below are general instructions on how to use the catalogs and important information on file format and map viewing options.  Refer to the User’s Guide for more detailed instructions.  Hint:  Within the catalogs, use the Abode Find tool to locate specific products – you can search by keyword or file name.


BLM & DOI Personnel
You can access all the products below plus more through the REA SharePoint site!   More info


BLM - Do you need ArcMap?
You can access ArcGIS Desktop and work directly with REA data, maps, and models! More info

The Data Portal allows users to download data sets one at a time. For batch downloads (greater than 20 data sets), please Contact Us .

Data
All non-proprietary REA data are available for download through the Data Catalogs listed above.  Data Catalogs describe each available data set and provide a hyperlink to download it.  Simply open the Data Catalog, click on a Download hyperlink, and save the data. 

Data are provided in data packages, formatted either as a layer package file (.lpk) or zipped file (.zip).   Each package contains a data set, its metadata, and a layer file (containing symbology information to display the data).  Once saved, unpack or unzip the data package to access the files within it.  See the User’s Guide for more information on REA data.

Maps
There are dozens of maps available for viewing and download through the Map Catalogs listed above, including those published in the final REA reports.  Map Catalogs describe each map and provide a hyperlink to view it in either ArcGIS.com or through a Map Service (see the information below).  Simply open the Map Catalog and click on the ArcGIS.com or Map Services hyperlink to view a map.  Alternatively, click on a map in a final report to view it in ArcGIS.com.  See the REA Data Portal User’s Guide for more information on REA maps.

ArcGIS.com:   Click on the ArcGIS.com hyperlink in the Map Catalog to view a map online.  In ArcGIS.com, you can interact with the REA data, add additional data, and create a customized map.  You do not need any GIS software to use ArcGIS.com, only Internet access. 

Map Services:   If you would like to view a map through a specific application (such as ESRI ArcMap), click on the Map Service link in the Map Catalog.  You will be directed to a Services Directory from which you can elect to view a map in ArcMap, ArcGIS Explorer, or Google Earth.  You must have these applications installed first.

Models
Models are currently available only in draft format, to be used as a reference for the geoprocessing methods used in REAs.  The models have not been fully documented and are not functioning executable tools.  Check back for final models in late 2013.

All non-proprietary geoprocessing models used in an REA are available for download through the Model Catalogs listed above.  Model Catalogs describe each model and provide a hyperlink to download it and its supporting documentation.  Simply open the Model Catalog, click on a Download hyperlink, and save the file.

Models are provided as zipped files (.zip), that contain models and/or script files and supporting documentation.  Models and script files come in a variety of formats, but are primarily ArcGIS Toolboxes (.tbx) and Python scripts (.py).   To view the models or scripts, you must have the corresponding software applications installed first (e.g., to view a Toolbox file you need to use ArcMap or ArcCatalog).  See the REA Data Portal User’s Guide for more information on REA models.

REA SharePoint Site (BLM, DOI, or REA Collaborators only)
DOI personnel or REA Collaborators can visit the REA SharePoint site.  The SharePoint site provides access to all the products listed in the REA Data Portal plus other REA products such as the final reports, task memos, presentations, reference tools, and more.  The SharePoint site also offers additional functionality within the data, map and model catalogs that facilitates searches such as sorting, filtering, and cross-referencing. Read the REA Sharepoint User’s Guide to learn about the contents of the site.

DOI Personnel:   Log into the REA SharePoint using your Windows Active Directory username and password.  Include your agency domain with your username (e.g., blm\jsmith). 

REA Collaborators:   Persons outside of the DOI who are collaborating on an REA can request access to the REA SharePoint site through their AMT Lead.  See the REA Sharepoint Users's Guide for information on how to request SharePoint sponsorship.  Once you are sponsored, log into the REA SharePoint with your username and password and include the BLM domain with your username (e.g., blm\jsmith).

ArcGIS Desktop (BLM personnel only)
BLM personnel who do not have access to ESRI ArcGIS Desktop applications (i.e., ArcCatalog and ArcMap) can access them by logging into Citrix.  Read the Citrix User’s Guide to learn about how to access ArcGIS Desktop and REA products through Citrix. 

All BLM Personnel:   

  • Log into Citrix to work directly with REA data, maps, and models whether you have a local installation of ArcGIS or not.  Using Citrix will increase speed and performance. 
  • Before logging into Citrix, use the data, map and model catalogs to learn about what REA products are available to you.  The catalogs provide an easily searchable format that does not require you to understand the directory structure or file naming convention used to manage the thousands of REA files.
  • Files in the REA directory are read-only.  You must save a local copy to edit it.
  • Log into Citrix using your Windows Active Directory username and password.
