## Setup
``` python
try:
import ee_jupyter
print('ee_jupyter was already installed.')
except ModuleNotFoundError:
print('ee_jupyter was not found. Installing now...')
import os
result = os.system('pip -q install earthengine-jupyter')
```
Make sure that the earthengine-jupyter package is installed...
## How to use
This lib contains a
[`Map`](https://googlestaging.github.io/earthengine-jupyter/ipyleaflet.html#map)
class that can be used to display an interactive map.
``` python
import ee
from ee_jupyter.core import authenticate_if_needed
from ee_jupyter.ipyleaflet import Map
```
``` python
authenticate_if_needed()
```
✓ Authentication credentials were found.
``` python
# Intialize the Earth Engine client library.
ee.Initialize()
```
``` python
map1 = Map(center=(37.5924, -122.09), zoom=8)
map1
```
Map(center=[37.5924, -122.09], controls=(ZoomControl(options=['position', 'zoom_in_text', 'zoom_in_title', 'zo…
Define an Earth Engine image layer, and add it to the interactive map.
``` python
img1 = ee.Image("LANDSAT/LC09/C02/T1_L2/LC09_044034_20220127")
visualization = {
'bands': ['SR_B4', 'SR_B3', 'SR_B2'],
'min': 0.2 / 0.0000275,
'max': 0.4 / 0.0000275,
}
map1.addLayer(eeObject=img1, visParams=visualization, name='Landsat scene')
```
We can also create an inspector object and associate it with the
previously created map.
``` python
from ee_jupyter.ipyleaflet import Inspector
inspector1 = Inspector(map_object=map1)
inspector1
```
Inspector(layout=Layout(border_bottom='solid', border_left='solid', border_right='solid', border_top='solid', …
Typically when you create a inspector object, you will want to display
it near the map.
``` python
from ipywidgets import HBox
display(HBox([map1, inspector1]))
```
HBox(children=(Map(center=[37.5924, -122.09], controls=(ZoomControl(options=['position', 'zoom_in_text', 'zoom…

# Displaying a Map Image
If you want to display a static (non-interactive) image, you can do that
as well. The `embed=True` parameter will allow the image to be saved
within the notebook.
``` python
from IPython.display import Image
visualization['dimensions'] = 400 # maximum dimension for the image
url = img1.getThumbUrl(visualization)
Image(url=url, format='png', embed=True)
```
