Overview

Example datasets and configuration for ERDDAP.

Uses the ERDDAP Docker image.

You can view this setup live at https://standards.sensors.ioos.us/erddap/index.html, with documentation at https://ioos.github.io/ioos-metadata/gold-standard-examples.html.

Download

You should git clone or download and unzip this repository from the green "Clone or download" button. Once cloned or downloaded, move into the directory.

$ ls
datasets erddap .gitignore README.md

Run

docker run --rm \
  --name erddap_gold_standard \
  -p 8080:8080 \
  -v $(pwd)/erddap/conf/config.sh:/usr/local/tomcat/bin/config.sh \
  -v $(pwd)/erddap/conf/robots.txt:/usr/local/tomcat/webapps/ROOT/robots.txt \
  -v $(pwd)/erddap/content:/usr/local/tomcat/content/erddap \
  -v $(pwd)/erddap/data:/erddapData \
  -v $(pwd)/datasets:/datasets \
  -v /tmp/:/usr/local/tomcat/temp/ \
  --env ERDDAP_MIN_MEMORY=1G --env ERDDAP_MAX_MEMORY=2G \
 axiom/docker-erddap:2.18

or

docker-compose up -d

After startup, go to http://localhost:8080/erddap/index.html

You can monitor http://localhost:8080/erddap/status.html to see the status of dataset loading. If a dataset fails to load, you can see logs under $(pwd)/erddap/data/logs.

Note: ERDDAP caches datasets, so if you change one, you can force refresh by creating a file under $(pwd)/erddap/data/hardFlag/, for example touch $(pwd)/erddap/data/hardFlag/41024-sun2-sunset-nearshore. See ERDDAP docs on flags.

Modify

These instructions are minimal, and are intended to get you up and running quickly so that you can test out ERDDAP. For full instructions on how to set up your own ERDDAP server, see https://coastwatch.pfeg.noaa.gov/erddap/download/setup.html

Configuration files overview

• datasets/ -- Sample datasets
• erddap/
  • erddap/conf/
    • erddap/conf/config.sh -- ERDDAP configuration
    • erddap/conf/robots.txt -- Search engine crawler config
  • erddap/content/
    • erddap/content/datasets.xml -- Datasets configuration, references data in datasets/ above
    • erddap/content/images/erddap2.css -- CSS overrides

Update config.sh

Set the following variables in config.sh

Configure your institution

Update the <admin.*> tags by setting:

ERDDAP_adminInstitution=""
ERDDAP_adminInstitutionUrl=""
ERDDAP_adminIndividualName=""
ERDDAP_adminPosition=""
ERDDAP_adminPhone=""
ERDDAP_adminAddress=""
ERDDAP_adminCity=""
ERDDAP_adminStateOrProvince=""
ERDDAP_adminPostalCode=""
ERDDAP_adminCountry=""
ERDDAP_adminEmail=""

Configure email

Update the <email.*> and <emailEverythingTo> tags by setting:

ERDDAP_emailEverythingTo=""
ERDDAP_emailDailyReportsTo=""
ERDDAP_emailFromAddress=""
ERDDAP_emailUserName=""
ERDDAP_emailPassword=""
ERDDAP_emailProperties=""
ERDDAP_emailSmtpHost=""
ERDDAP_emailSmtpPort=""

Update for your domain

Update <baseUrl>, <baseHttpsUrl> and <flagKeyKey> to match your domain by setting:

ERDDAP_baseUrl=""
ERDDAP_baseHttpsUrl=""
ERDDAP_flagKeyKey=""

Adding a new dataset

Steps

1. Add your nc file to datasets/.
2. Run sh GenerateDatasetsXml.sh. Results will output to the console and logs/.
3. Copy the resulting <dataset> to erddap/content/datasets.xml
4. Restart ERDDAP

Example

Say you have a file called seward-sealife-center-astra.nc that you've added to datasets/.

sh GenerateDatasetsXml.sh

*** GenerateDatasetsXml ***
Press Enter or type the word "default" (but without the quotes)
  to get the default value.
Type the word "nothing" (but without quotes) or "" (2 double quotes)
  to change from a non-nothing default back to nothing (a 0-length string).
Press ^D or ^C to exit this program at any time.
Or, you can put all the answers as parameters on the command line.
Results are shown on the screen and put in
/erddapData/logs/GenerateDatasetsXml.out
DISCLAIMER:
  The chunk of datasets.xml made by GenerateDatasetsXml isn't perfect.
  YOU MUST READ AND EDIT THE XML BEFORE USING IT IN A PUBLIC ERDDAP.
  GenerateDatasetsXml relies on a lot of rules-of-thumb which aren't always
  correct.  *YOU* ARE RESPONSIBLE FOR ENSURING THE CORRECTNESS OF THE XML
  THAT YOU ADD TO ERDDAP'S datasets.xml FILE.

*** generateDatasetsXml finished successfully.

The resulting <dataset> is in logs/GenerateDatasetsXml.out. Copy this into datasets.xml and reload ERDDAP.

Troubleshooting

The DasDds tool can help you find errors in datasets.xml, it is an interactive tool that will prompt you for a dataset ID.

sh DasDds.sh

You can find a log of what happened at logs/DasDds.out
