# gdal2mbtiles: Python-based tools for creating OGC MBTiles.
MBTiles Specification [[RU]](http://gis-lab.info/qa/mbtiles-spec.html), [[EN]](https://github.com/mapbox/mbtiles-spec)

# Introduction

* Combination of multiprocess [gdal2tiles](https://github.com/bolshoydi/gdal2tilesp) and [mbutil](https://github.com/mapbox/mbutil) 
in order to write tiles directly into Mbtiles database.
* Writing tiles without transitional (temporary) storage on disk
* Works in both ways: as CLI script and from interface. Just launch `window.py` from gui

# Requirements

* [GDAL 2.X.X](https://pypi.python.org/pypi/GDAL/)
* [PIL\Pillow] (https://pypi.python.org/pypi/Pillow/4.0.0)
* [PyQt4](https://pypi.python.org/pypi/PyQt4/4.11.4)
