Make coastsat into a package

[borgstad]

In order to use coastsat, you have to set your pythonpath/start your environment with coastsat as root dir.

It would be really nice if CoastSat existed as an installable package.

If you are interested, I could create a PR

[kvos]

that would be great @borgstad and highly appreciated by new users!

I rememeber having some issues when installing the packages with pip, especially the gdal package (which still causes issues #54 ). Are you thinking about something like pip install coastsat?

[borgstad]

Yes exactly, pip install coastsat.

About the gdal issue: I will look into that and report back my findings. I have previously had problems with gdal and conda/pip.

[borgstad]

GDAL cannot be installed via pip on either Windows or Linux, as it needs a precompiled binary.
As things are right now, coastsat can only be installed after the user has setup a conda environment containing gdal and co.

I have nonetheless created a pull request, adding a little bit to the Readme, and a setup.py file.. Atleast it takes the burden away of messing with PYTHONPATH and the location of the coastsat library

[cosstas]

I too believe that coastsat should (additionally) be available via pip. Pre-requisite GDAL binaries can be installed separately from wheels (GDAL) created and maintained by Christoph Gohlke.
For example, rasterio is using a similar installation approach using Binary Distributions.

thanks @borgstad for looking this up and making a PR #60, much appreciated. The only minor change is that I wouldn't call the package CoastSatDHI (or with the name of any organisation, includng mine) as we don't want to do any branding here but just open-source community development.

Since there are still issues with the GDAL package, it's worth having a discussion on what are the possible options to make the installation of coastsat as simple as possible. About half of the issues opened by users are on the installation!

From @cosstas suggestion above we could also run a command to download the GDAL wheels separately and then install with pip.
What about making a package on conda-forge, is that an option as well?

One thing to keep in mind is that structure of coastsat is still evolving and we want to keep it flexible so that users can just pull the changes from github without having to re-install the package each time.

Keen to have current users opinion on this

This is definitely an error on my part, I pushed a wrong version, sorry about the confusion, I will updated it as soon as I have time.

Nice suggestion!

I am in favor of recommending to the user of the most favorable way to install GDAL manually on each platform. In my experience, this is the common practice for pypi packages that require GDAL. At least to begin with.

If coastsat is following a release schedule in pypi, (at least for major updates) a simple
pip install --upgrade coastsat
would do. Advanced users can always clone from git for current development.

@kvos coastSat is applicable for island?;downloading images is possible but further steps end with an error

[cosstas]

Today I found some time to install CoastSat and have a go at it. I copied the sources in my site-packages folder. Earth engine and google api were installed using pypi. The rest were already already installed manually as described before. And that was all, I was able to run the example.
It has been almost a year and there was no update regarding the pypi package. Why is it so important to make CoastSat 100% install-able with pypi? Why can't we let pip install all the pre-requisites by itself and let the user manually install GDAL?

[kvos]

there have been so many issues open because of the installation process that any update that could make the installation easier is more than welcome. What is required to make a pypi package?

[cosstas]

Haven't published a package myself, but since @borgstad committed #60, I think the maintainer (you:-)) must create an account with PyPI, create a package and upload it. The instructions in this link (https://packaging.python.org/tutorials/packaging-projects/) are straightforward and don't look that demanding. I suppose maintaining both a conda repository and a PyPI package adds some effort to publishing a version.

[cosstas]

I am working towards creating a PyPi package. First of all setup.py needs be defined so that pip install can work. @kvos (or anyone else interested) Can you try installing CoastSat from my branch using the following command:
pip install https://github.com/cosstas/CoastSat/archive/v1.1.1-alpha.8.tar.gz
This release is just the current master with setup.py added. Requirements are something to be tweaked by @kvos should the rest of installation procedure works out. GDAL still needs to be already installed.
Any comments or suggestions are welcome.
