How To's and Handouts
Below are training resources for the Rapid Ecoregional Assessments (REA).
BASICS include two videos for people who are new to REAs:
- "What is an REA" - This module reviews where the REAs are located, the components of an REA, how REAs are conducted, and how REAs enhance local management.
- "How to conduct an REA" - This module reviews how REAs are conducted, including the different phases of the assessment, the major products, and the people involved.
HOW TO's illustrate how you can access data, maps, and reports produced by the REAs whether you have access to BLM systems or are a member of the Public. Most of these are used in REA workshops and are updated when major changes are made.

HOW TO's
How to Access REA Products: REA data, maps, and models can be accessed through the Explore REA Data by all users, and the NOC EGIS Citrix (BLM users only). This document includes links to map services (all users). (Updated September 2017)
How To Access REA Data, Maps, and Models Using the Landscape Approach Data Portal - A users' guide to the landscape approach data portal (Public access). (Updated September 2017)
ArcGIS Online (AGOL) Resources for BLM Users:
1. How to gain access to BLM EGIS SAML account to access AGOL including guidelines, mobile accounts, and a description of custom access roles with permissions.
2. List of ESRI Classes on how to make maps using GIS data and AGOL (ArcGIS Online) - AGOL simplifies the map making process, allowing users to make their maps without having to deal with data downloads and pre-processing issues. Most agencies (including BLM) and other entities now release their data as web services that can be brought into AGOL. Complex analyses that can be found in Desktop ArcGIS remain somewhat limited in AGOL but the basics are in place.
REA Naming Conventions are standardized abbreviations that can be used to decipher the files contents whether it be data, map, or model files. For example: all file names begin with a 3-letter code that designates an REA; e.g., "COP" = Colorado Plateau, "NGB" = Northern Great Basin, and so on.
Besides using REA data, the REA Applications group has branched out to use other broad scale data sources. These are often data sources that are used in REAs, used for analysis of an area outside of the area covered by an REA or other nation-wide or west-wide data sets from reputable sources. See the Sources of Broad Scale Data story map for an interactive introduction to the data.(Updated September 2017)
Using Citrix to Access REA Data
Learn how to use BLM NOC EGIS Citrix to access REA data, maps, and models directly using ArcGIS and other applications. (BLM only. Updated September 2017)
