Georeferencing for Research Use, short course report |
October 4 - 7, 2016 at (https://www.nceas.ucsb.edu/) NCEAS, Santa Barbara California
We welcome you to this short course, with a focus on research use of georeferenced natural history collections data. We will include activities and discussions about best practices and tools for georeferencing, capturing locality data in the field, and using georeferenced specimen locality data in research. Attendees must have a basic level of experience with georeferencing techniques and tools and be researchers or directly involved with researchers.
After the workshop, we will encourage our participants to share use cases, any training materials developed, and to offer workshops, webinars, talks, or other events aimed at increasing use of best practices for georeferencing legacy locality data, best practices for capturing the locality data from future biological and paleontological collecting and sampling events, and best practices for using the data in research.
Some anticipated course content includes discussion and activities about georeferencing integration, georeferenced data visualization, and georeferences for modeling and research. Detailed agenda in development.

Bring your Datasets and Laptops:
Participants are strongly encouraged to bring representative datasets from their collections or research that need georeferencing to expose everyone to the variety of locality data georeferencing issues and give the experts and participants a chance to work together to address any challenges.
Participants must bring their own laptops and everyone will have wired access to facilitate the best possible workshop experience.

- Please install the following software
- QGIS and then QGIS Plugins. NOTE it's easy to install all the plugins from inside QGIS once you have it installed.
- QGIS: http://qgis.org/en/site/forusers/download.html
- QGIS Plug-ins: Open your QGIS installation on your laptop > navigate to Plugins > Manage and Install Plugins (as seen in the screenshots). You can then add these plugins within QGIS by typing the tool name into the search box and clicking on "Install Plugin": Clipper, Coordinate Capture, GPS Tools, Heatmap, Interpolation, OpenLayers, Processing, TimeManager, and Lifemapper.
- Clipper (clip intersecting vector features)
- Coordinate Capture (find coordinates in various coordinate reference systems (CRS) via mouse-over)
- Gazetteer Search (finding named places via a search bar): NOTE: The Gazetteer Plugin is not "discoverable" through the Plugins manager in QGIS. You'll need to follow the installation steps listed here: https://github.com/AstunTechnology/QGIS-Gazetteer-Plugin#Installation
- Manual
- find where your QGIS is installed on your machine
- right click the folder to see contents and find the folder for Plugins
- for example, on Deb's Windows 10 laptop, the path to the correct QGIS plugins folder is C:\Users\dlpss\.qgis2\python\plugins
- make a folder called gazetteersearch inside of the QGIS Plugins directory
- download the contents from GitHub and move them into the gazetteersearch folder
- close and reopen QGIS in order for the plugin to show up
- via Git
- clone the repository into your QGIS Plugins folder following the steps from the link above. Please let Sara know if you have any other questions.
- Manual
- GPS Tools (loading and importing GPS data)
- Heatmap (generate a heatmap raster given input vector points)
- Interpolation (interpolation techniques given vertices of a vector layer)
- OpenLayers (load basemaps from OpenStreetMap, Google, etc.)
- Processing (spatial data processing framework)
- TimeManager (event-visualization animation for vector features)
- Lifemapper: Plugin for Lifemapper webservices for SDM modeling, and multispecies Presence Absence Matrix (PAM) analysis. The tool allows you to build SDM models using GBIF, iDigBio, or user supplied species occurrence data.
- Gazetteer Search requires an additional step; follow these steps to install (manual):
- find where your QGIS is installed on your machine
- right click the folder to see contents and find the folder for Plugins
- make a folder called gazetteersearch inside of the QGIS Plugins directory
- download the contents from GitHub and move them into the gazetteersearch folder
- close and reopen QGIS in order for the plugin to show up
- OR install via command line (using Git - see instructions in link above)
- clone the repository into your QGIS Plugins folder following the steps from the link above.
- Open Refine: (previously Google Refine) is a tool for data cleaning that runs through a web browser, and any browser - Safari, Firefox, Chrome, - should work fine (Explorer not recommended). You will need to download Google Refine and install it, and when you open it, it will run through the browser, but you don't need an internet connection, and the data will all be stored on your computer. (Use these resources Open Refine Install or Install Open Refine for more help if you run into any Open Refine install issues).
- Windows
- Go to the OpenRefine download page.
- Click on Windows kit to download the install file
- To use it, unzip, and double-click on openrefine.exe (if you're having issues with openrefine.exe try refine.bat instead)
- OpenRefine will then open in your web browser.
- If it doesn't open automatically, open a web broswer after you've started the program and go to the URL
http://localhost:3333
and you should see OpenRefine.
- MacOS
- Go to the OpenRefine download page.
- Click on Mac kit to download the install file
- Open the downloaded .dmg file
- Drag the icon in to the Applications folder
- Double click on the icon and Google Refine will then open in your web browser.
- If it doesn't open automatically, open a web broswer after you've started the program and go to the URL
http://localhost:3333
and you should see OpenRefine.
- Linux
- Go to the OpenRefine download page.
- Click on Linux kit to download the install file
- Download and extract
- Type
./refine
in your terminal and Google Refine will then open in your web browser. - If it doesn't open automatically, open a web broswer after you've started the program and go to the URL
http://localhost:3333
and you should see OpenRefine.
- Windows
- Spreadsheet software (your choice, Libre Office, Excel, etc.,)
- We'll be using a spreadsheet program. If you already have a spreadsheet program installed, like LibreOffice, Excel or OpenOffice, you can use whatever you already have. If you don't have a spreadsheet program, please download and install LibreOffice from http://www.libreoffice.org/download/libreoffice-fresh/
- Java: Please make sure you have Java installed (needed for Open Refine to work).
- QGIS and then QGIS Plugins. NOTE it's easy to install all the plugins from inside QGIS once you have it installed.
- OPTIONAL software install and tutorials - if you are interested in the R breakout section we will offer at the workshop.
- R & RStudio: R is a programming language that is especially powerful for data exploration, visualization, and statistical analysis. To interact with R, we use RStudio.
- Windows
- Video Tutorial
- Install R by downloading and running this .exe file from CRAN (http://cran.r-project.org/index.html).
- Also, please install the RStudio IDE.
- Mac OS X
- Video Tutorial
- Install R by downloading and running this .pkg file from CRAN (http://cran.r-project.org/index.html).
- Also, please install the RStudio IDE.
- Linux
- You can download the binary files for your distribution from CRAN. Or you can use your package manager
- e.g. for Debian/Ubuntu run
sudo apt-get install r-base
and for Fedora runsudo yum install R
.
- e.g. for Debian/Ubuntu run
- Also, please install the RStudio IDE.
- You can download the binary files for your distribution from CRAN. Or you can use your package manager
- Windows
- Then install packages:
- R Tutorials. OPTIONAL take a short course in R. If you are a novice, take a beginner course. We don't expect you know know R well, but we do need you be familiar enough to follow along with one of our optional hands-on sessions. There are several good options:
- Try R (Code School course)
- Beginner Course: Up and Running with R with Barton Poulson (course at lynda.com)
- Intermediate Course: R Statistics Essential Training with Barton Poulson(course at lynda.com)
- For the future you could take a Coursera class. intro to R(Coursera course started August 22nd).
- Georeferencing using Apps: please install either of these on your device, if you want to try georeferencing this way to compare with results from a GPS unit.
- R & RStudio: R is a programming language that is especially powerful for data exploration, visualization, and statistical analysis. To interact with R, we use RStudio.
