NAIP STAC Item added to map as layer disappears on zoom out, needs a very close zoom level to appear.

Environment Information

• leafmap version: 0.30.1
• Python version: 3.10
• Operating System: Ubuntu

Description

I want to zoom out and see my image on the map. But it disappears at far away zoom levels. Also the default zoom level that is set when the map opens won't show the image.

What I Did

import pystac_client
import planetary_computer
from shapely.geometry import Point

area_of_interest = Point((-121.034, 36.990)) # wright solar farm lon lat
catalog = pystac_client.Client.open(
    "https://planetarycomputer.microsoft.com/api/stac/v1",
    modifier=planetary_computer.sign_inplace,
)

range_old = "2010-01-01/2013-01-01"
range_new = "2020-01-01/2021-01-01"

search_old = catalog.search(
    collections=["naip"], intersects=area_of_interest, datetime=range_old
)

search_new = catalog.search(
    collections=["naip"], intersects=area_of_interest, datetime=range_new
)

items_old = search_old.item_collection()
items_new = search_new.item_collection()

print(f"{len(items_old)} Items found in the 'old' range")
print(f"{len(items_new)} Items found in the 'new' range")

map = leafmap.Map()

leafmap.stac_assets(collection="naip", item=items_old[0].id, titiler_endpoint="pc")

m = leafmap.Map()
m.add_stac_layer(
    collection="naip",
    item='ca_m_3612108_ne_10_1_20120622_20120904',
    assets=["image"],
    name="Old image 2012 before solar development",
)
m

Thank you for reporting. I can confirm that I encourter the same issue with NAIP imagery. However, I suspect this is an issue with Planetary Computer rather than leafmap. Check out the example below using Landsat imagery. The layer does not disappear when zoomed out. Leafmap uses the same mechanism to display PC data. If it is indeed a leafmap issue, I would expect both NAIP and Landsat data to experience the same issue. I look into the source code of the stac_tile function, but could not identify any issues that could have caused this.
