A reusable Django app for raster datasets collaborative georeferencing.

The typical use case is the environmental and administrative organizations paper archive digitalization.

Features

--------

* Many datasets with different settings, coordinate systems and basemaps.

* make use of GDAL/OGR library.

* Requires no Gis/desktop skills:

    * simple control input

    * visual feedback

* responsive interface

==============

REQUIREMENTS

==============

Required python libraries:

* django

* django-apps

* django-cors-headers

* django-http-proxy

* python-slugify

* django-imagekit

* django-raster

* pygdal

Required libraries:

GDAL/OGR 2.0 http://www.gdal.org/

==============

INSTALL

==============

Last stable version:

::

    pip install django-warp

Development version:

::

    pip install django-warp

=====

USAGE

=====

* Add ``django.contrib.gis``, ``httpproxy``, ``django_warp`` to your ``INSTALLED_APPS``

* Define ``MEDIA_URL``, ``MEDIA_ROOT``, ``STATIC_URL``, ``STATIC_ROOT``

* Add  ``url(r'^warp/', include('django_warp.urls')),`` to urlpatterns in site ``urls.py``

* Append ``+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)`` to urlpatterns. A minimal ``urls.py`` should be like this:

::

    from django.conf.urls import include,url

    from django.conf.urls.static import static

    from django.conf import settings

    urlpatterns = [

        ...

        url(r'^warp/', include('django_warp.urls')),

    ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

* ``./manage.py makemigrations django_warp`` and ``./manage.py migrate`` to create db context

* Run server and browse to ``[yourserver address]\warp\`` and login with a valid site credentials

* First create a dataset with epsg code, extents and baselayer

* Then upload images and define correlation and clipping to do georeferencing

=====
