Basic Interactive Mapping with hagerstrand¶

In [8]:

import hagerstrand as hs
import ee

In [9]:

# Create interactive map with hagerstrand
Map_hs = hs.Map(center=[23.1291,113.2644], zoom=4)

In [10]:

# Initialize Earth Engine
hs.ee_initialize()

In [11]:

# Center map
Map_hs = hs.Map(center=[35.9606,-83.9207], zoom=10)

In [12]:

Map_hs

Add a file to an interactive map¶

In [11]:

from IPython.display import Video

Video(r"../../examples/videos/Add_File.mp4", height=500, width=750)

Out[11]:

Change basemap¶

In [12]:

Video(r"../../examples/videos/Change_Basemap.mp4", height=500, width=750)

Out[12]:

In [7]:

# Add geojson to map
#Map_hs.add_geojson("../../examples/data/cbg_poi_lines.json", layer_name="CBG to POI")

Basic Interactive Mapping with geemap¶

In [13]:

import geemap

In [14]:

# Initialize Earth Engine
geemap.ee_initialize()

# Create interactive map with geemap
Map_gee = geemap.Map(center=[23.1291,113.2644], zoom=4)

In [15]:

# Add basemap
Map_gee.add_basemap('Esri Transportation') # Esri Transportation

In [16]:

# Focus on Guangzhou area
geometry = ee.Geometry.Polygon(
        [[[113.2644,25.1291],
          [113.2644,23.1291],
          [111.2644,21.1291],
          [114.2644,23.1291]]])
Map_gee.centerObject(ee.FeatureCollection(geometry), 10)

In [17]:

# Adding a feature of China

countries = ee.FeatureCollection("USDOS/LSIB_SIMPLE/2017")
country = countries.filter(ee.Filter.eq('country_na', 'China'))

Map_gee.addLayer(country, { 'color': 'red' }, 'feature')

In [18]:

Map_gee

In [14]:

#Map.setCenter(-74.0080, 40.637, 16) # I think the best egg tarts in NYC are at Xinfa Bakery in Brooklyn's Chinatown :-)
