Create MBTiles from GDAL files.

Project description

# gdal2mbt

*Create MBTiles from a GDAL file*

## Requirements

- Python 2.7

## Installation

pip install

Or from source

git clone
pip install -e gdal2mbt

## Creating a MBTile file

gdal2mbt create goteborg.mbtiles 8 goteborg.vrt

Or use a JSON config file with an optional metadata dictionary that will
overwrite the defaults in the MBTiles metadata table.

"source": "goteborg.vrt",
"num_levels": 8,
"metadata": {
"name": "goteborg",
"description": "Aerial photos over Göteborg city"

gdal2mbt create -c goteborg.json goteborg.mbtiles

To resume an aborted MBTiles creation process pass the `-r` flag to `create`.

## Parallel jobs

Speed up MBTiles creation by distributing the load over several processors or
even computers by using [GNU Parallel](

Create an MBTiles file for each tile on zoom level 0, this will depend on the
second argument which defines how many zoom levels to generate in total.

gdal2mbt config goteborg.vrt 6 | parallel gdal2mbt create -c

Merge all the created MBTiles to one.

gdal2mbt merge goteborg.mbtiles goteborg.*.mbtiles

Or to squash all MBTiles into one to save space use the destructive `-s` flag
which will remove each merged MBTiles file.

gdal2mbt merge -s goteborg.*.mbtiles

Add zoom levels that might have been omitted due to the amount of tiles on zoom
level 0 at time of creation.

gdal2mbt levels goteborg.mbtiles 8
