heremaps / here-map-widget-for-jupyter Goto Github PK

The Map seems not to trigger a bounds name change event like ipyleaflet does. I see a zoom and center one, but it would be much easier to not have to calculate the bounds from that.

After creating/showing a MapSettingsControl it seems impossible to add layers to it such that they appear in the control. It would be nice to see that happen like in ipyleaflet.LeayersControl.

import os
from here_map_widget import (Map, DefaultLayers, DefaultLayerNames,
    GeoJSON, MapSettingsControl, ZoomControl)

api_key = os.getenv("HEREMAPS_API_KEY")
basemap = DefaultLayers(layer_name=DefaultLayerNames.raster.normal.map)
m = Map(center=[52.5, 13.4], zoom=10, basemap=basemap, api_key=api_key) 
m.add_control(ZoomControl(alignment="LEFT_TOP"))
basemaps = [DefaultLayerNames.raster.normal.map, DefaultLayerNames.raster.normal.transit]
url = "https://raw.githubusercontent.com/johan/world.geo.json/master/countries.geo.json"
layers = [GeoJSON(url=url)]
layers = [{"label": "countries", "layer": GeoJSON(url=url)}]
msc = MapSettingsControl(basemaps=basemaps, layers=layers)

# does not add second layer
msc.layers.append({"label": "countries2", "layer": GeoJSON(url=url)})

m.add_control(msc)

# does not add second layer
msc.layers.append({"label": "countries2", "layer": GeoJSON(url=url)})

m

It seems one can install this package on Pyodide and hence JupyterLite using micropip, but the maps don't show, yet, indicating there is some issue with the JupyterLab extension. You can try on JupyterLite. Maybe worth giving a thought?

import micropip
await micropip.install(
    "https://opencomputinglab.github.io/vce-wheelhouse/wheelhouse/"
    "MarkupSafe-2.0.1-py2.py3-none-any.whl"
)
await micropip.install("here-map-widget-for-jupyter")
from here_map_widget import Map

api_key = "******"
m = Map(api_key=api_key, center=[52.51, 13.39], zoom=4)
m  # gives: Loading widget...

Does the here map widget have a Layers Control, similar to the ipyleaflet Layers Control? I can't seem to find it on the API Reference.

https://ipyleaflet.readthedocs.io/en/latest/api_reference/layers_control.html

This widget definitely needs an update...

I can add controls and layers only with map.add_control() and add_layer() but I would also like to use += on the map as this shortens the code considerably when putting many things onto the map. In Ipyleaflet this is perfectly possible. It would be nice to have it here, too (no pun intended).

import os
from here_map_widget import Map, DefaultLayers, DefaultLayerNames, ZoomControl

api_key = os.getenv("HEREMAPS_API_KEY")
basemap = DefaultLayers(layer_name=DefaultLayerNames.raster.normal.map)
m = Map(center=[52, 13], zoom=6, basemap=basemap, api_key=api_key) 
m.add_control(ZoomControl(alignment="LEFT_TOP"))  # preferred: m += ZoomControl(...)

Thank you for developing this awesome package. I particularly like the 3D feature, which ipyleaflet is lacking.

Do you plan to support XYZ and WMS tile layers? I would love to incorporate this package into geemap if it can support XYZ and WMS tile layers. Thanks.

I want to display really big geometric shapes on the surface of a map, think boxes of arbitrary height using the extrusion parameter of a Rectangle, say. But in code like below, similar to this the rectangle is rendered only for values up to a maximum of 2047 (meters?). Above this number no rectangle is rendered.

The official documentation mentions map.Polygon.MAX_EXTRUDE_HEIGHT, but it seems not to be supported in Python. Can it be set higher than 2047 and can it be exposed in Python?

import os
from here_map_widget import Bbox, Map, Rectangle

api_key = os.environ["LS_API_KEY"]
lon, lat = [50, 13]
m = Map(api_key=api_key, center=[lon, lat], zoom=8)
style = {"strokeColor": "#829", "lineWidth": 4}
bbox = Bbox(top=lon + 0.5, left=lat - 0.5, bottom=lon - 0.5, right=lat + 0.5)
rectangle = Rectangle(bbox=bbox, style=style, elevation=0, extrusion=2047)
m.add_object(rectangle)
m

This project currently requires ipywidgets <8. However, versions 8.0.0 - 8.0.2 are available.

This project requires branca <0.5. However, version 0.6 is available.

It looks like the layout for ipywidgets is not properly handled. I've seen this for buttons (should be square in the example below), but it might happen with other elements, too.

import os
from ipywidgets import Button, Layout
from here_map_widget import Map, DefaultLayers, DefaultLayerNames, WidgetControl

api_key = os.getenv("HEREMAPS_API_KEY")
basemap = DefaultLayers(layer_name=DefaultLayerNames.raster.normal.map)
m = Map(center=[52.5, 13.4], zoom=10, basemap=basemap, api_key=api_key) 
layout = Layout(width="28px", height="28px")
btn = Button(icon="globe", layout=layout)
m.add_control(WidgetControl(widget=btn, alignment="LEFT_TOP"))
m

Widget should be supported to work on google colab

Maybe support the recently released Python 3.10 with according tests in GitHub actions. Just an idea.

It would be nice to have a transparent_bg parameter for WidgetControls like in ipyleaflet. ;)

Instructions
$ npm config set @here:registry https://repo.platform.here.com/artifactory/api/npm/here-node/
$ pip install here-map-widget-for-jupyter
$ jupyter nbextension install –py –sys-prefix here_map_widget
$ jupyter nbextension enable here_map_widget –py –sys-prefix

Code
from here_location_services import LS
from here_map_widget import Map, GeoJSON
ls = LS(api_key=my_key)

address = "Invalidenstr 116, 10115 Berlin, Germany"
gc_response = ls.geocode(query=address)

data = gc_response.to_geojson()
geo_layer = GeoJSON(data=data)

m = Map(api_key=my_key, center=[52.53086, 13.38469], zoom=12)
m.add_layer(geo_layer)
m

does not display map widget

Any outlook on the current status and further development is highly appreciated.

It looks like the Map object bounds are actually South, North, East, West
