Enhancing discovery of geospatial datasets in data repositories

Project Goal

This project closes the gap between geospatial data formats and repositories and similarity measurements. Or group extended an existing Free and Open Source Software (FOSS) - Zenodo - with the functionality to retrieve and view similar records. This comprises both the API and UI, namely providing an HTTP endpoint to retrieve an ordered list of records based on a provided record and displaying similar records.

For all installationsteps we presuppose pip and python ❗️

Zenodo - Installation:

Here you can find our Zenodo-Repository:
https://github.com/corneliazy/zenodo

For Zenodo installation, please follow the instructions below:
https://github.com/corneliazy/zenodo/blob/master/INSTALL.rst
(Who wants to save time, should not try it under Windows. On Linux its much faster and easier 😉 )

After installation execute:

pip install -e .

Now you can open http://localhost:5000/. There you can create your own profile and upload files.

If you have installed our version of zenodo you can find the integrated extractTool in your virtual enviroment in /Envs/zenodo/lib/python2.7/site-packages/extractTool

CLI-Tool

This installation was previously tested only with Linux, but should also work under Windows.

Installation Description (PyPi)

https://pypi.org/project/extractTool/

pip install extractTool

(you can write this command in your console and follow the installation description on the webside OR you can download the file and install the CLI tool local: )

Installation Description (local)

pip for pip install is required.

After downloading our Tool from PyPi To run our CLI tool, the following file must be executed in the project folder:

pip install -r requirements.txt --user (or sudo pip install -r requirements.txt) 

In this file all required plugins are listed, which we use in our tool.

Because sometimes there are some problems with the installation you must follow these next steps:
First, ensure you have gdal installed. I just run the following:

sudo apt-get install libgdal1i libgdal1-dev libgdal-dev

To get the version that apt-get provided you please run:

gdal-config --version

For example I get 2.2.3 so my pygdal version will be 2.2.3.3. (but replace the version with your version)

pip install pygdal==2.2.3.3

If you get some error you may look here

Next step:

pip install pytest   

Then you can navigate in any common console in the folder of the tool ("extractTool") and there, the following command must be executed

python extractTool.py --path='[filepath]' --detail=[bbox|convexHull] --time

for filepath you must insert a filepath to your testdata

--bbox ← for the bounding box of the file/folder (set as default)
--convexHull ← to get all the covexHull of the file/folder
--time ← (optionally) You can add this parameter to get additionally the timeextend

some examples

python extractTool.py --path='/home/maxmusterman/test1.geojson' --detail=bbox --time   
python extractTool.py --path='/home/maxmusterman/test2.nc' --detail=convexHull
python extractTool.py --path='/home/maxmusterman/testdict' --time

similarity calculation

Our similarity calculation code can be found in the similar.pyfile.
The associated tests are in the test_similar.py file.

Tests

Our tests can be executed with the command

pytest
