Digital terrain map manipulation high level functions

Project description

# Mapstery

Digital terrain map manipulation library.

High level scripts to convert, transform, manipulate small and large imagery
using GDAL in python to cover part of the needs of the NASA/ESA Frontier
Development Lab with respect to Space Resources challenges.

## Quick install

```
pip install mapstery
```

For developers, you might like to install the last version from git. So if you've
cloned _Mapstery_ in a folder called `mapstery_repo` then you could do the following:
`pip install mapstery_repo/`

NB: Make sure the gdal python package version correspond to the system gdal library.
If you have GDAL python installation problems you may have to match versions between
gdal system libraries and gdal python package, one way or another.

## Quick start

```
import mapstery
import numpy as np

M = mapstery.Map(500, 500)
M.add_band(np.ones((35,50))*128.0, "BAND_NAME_01")
M.add_band(np.ones((80,150))*89.0, "BAND_NAME_02")
M.save("/tmp/mastery_test0.gtif")
```

## Another example, combining layers
```
import mapstery
import numpy as np

M = mapstery.Map(500, 500)
M.dataset='layers.json'
M.save("/tmp/testjson.gtif")

```

## Json file example: layers.json
```
{
"BNAME":"LRO1.png",
"BNAME2":"LRO2.png"
}
# BNAME - BAND NAME
# LRO1.png - file path

```
## Dev infos

You can write your own scripts in `tests/` starting with the *dev_* prefix so that they are ignored by git.
