## Using Thredds Client

Read the Thredds tutorial on catalogs: [Thredds Catalog Primer](http://www.unidata.ucar.edu/software/thredds/current/tds/tutorial/CatalogPrimer.html)

### Get download URLs of a catalog

``` python
import threddsclient
urls = threddsclient.download_urls('http://example.com/thredds/catalog.xml')
```

### Get OpenDAP URLs of a catalog

``` python
import threddsclient
urls = threddsclient.opendap_urls('http://example.com/thredds/catalog.xml')
```

### Navigate in catalog

Start reading a catalog

``` python
import threddsclient
cat = threddsclient.read_url('http://example.com/thredds/catalog.xml')
```

Get a list of references to other catalogs & follow them

``` python
refs = cat.references

print refs[0].name
cat2 = refs[0].follow()
```

Get a list of datasets in this catalog

```python
data = cat.datasets
```

Get flat list of all direct datasets (data files) in the catalog

```python
datasets = cat.flat_datasets()
```

Get flat list of all references in the catalog

```python
references = cat.flat_references()
```

### Crawl thredds catalog

Crawl recursive all direct datasets in catalog following the catalog references. Stop recusion at a given depth level.

```python
import threddsclient
for ds in threddsclient.crawl('http://example.com/thredds/catalog.xml', depth=2):
print ds.name

```
