item.links() shouldn't be an dictionary instead of method?

[marujore]

Hi, I am new to sat-search and quite new to python
I was following the definitions in http://sat-utils.github.io/sat-api/?python#tocslinks
Based on that, on the bellow script, shouldn't "items.links" be accessed as dictionary containing "href, rel, type and title"? If I try access based on ['href'] I receive

TypeError: 'method' object is not subscriptable

The only way i could access was using items.links()

def sat_search(wlon,nlat,elon,slat,startdate,enddate,cloud,limit, collection):
	search = Search(bbox=[wlon, slat, elon, nlat],
                    time ='{}/{}'.format(startdate, enddate),
				    query={'eo:cloud_cover': {'lt': cloud},
						   'collection': { 'eq': collection}})
	
	items = search.items( limit = limit )
	print('%s items found' % len(items))
	print(items.summary( ['date', 'id', 'eo:cloud_cover', 'landsat:product_id']) )
	# print( items.calendar() )
	# items.save('test.json')

	scenes = {}
	for item in items:
		identifier = item.properties['landsat:product_id']
		scenes[identifier] = {}
		scenes[identifier]['sceneid'] = identifier
		scenes[identifier]['scene_id'] = item.id
		scenes[identifier]['cloud'] = int(item.properties['eo:cloud_cover'])
		scenes[identifier]['date'] = item.properties['datetime'][:10]
		scenes[identifier]['wlon'] = float(item.bbox[0])
		scenes[identifier]['elon'] = float(item.bbox[2])
		scenes[identifier]['slat'] = float(item.bbox[1])
		scenes[identifier]['nlat'] = float(item.bbox[3])
		scenes[identifier]['path'] = int(item.properties['eo:column'])
		scenes[identifier]['row'] = int(item.properties['eo:row'])
		scenes[identifier]['resolution'] = item.properties['eo:bands'][3]['gsd']
		scenes[identifier]['icon'] = item.assets['thumbnail']['href']
		scenes[identifier]['link'] = item.links()[0]
	return scenes

collection='landsat-8-l1'
wlon = -45.97 
elon = -45.80 
slat = -12.95
nlat = -12.89

startdate = '2018-01-01'
enddate = '2018-12-31'
cloud = 100#20
limit = 299
b = sat_search(wlon,nlat,elon,slat,startdate,enddate,cloud,limit, collection)		

Other observation, the search I performed also returned scenes that shouldn't overlap with my study area (my area is 220|069 and in search I also got from 074|069 a pacific ocean scene). I noticed that their bounding box are wrong (-179.11958 to 178.78202). I am using an if statement to eliminate them from my search. But this is a catalogation problem right?
if ( (item.bbox[0] - item.bbox[2]) > -3 ):

Almost 1 year since this opened! Closing since it's so stale, but to answer your questions:

• item.links is a method that can be used to return all links with a certain rel type, e.g., item.links('derived_from')
• the issue with the catalog is from the DevSeed sat-api deployment, which is outdated now but this issue can be raised there: https://github.com/sat-utils/sat-api/issues

I would recommend using https://earth-search.aws.element84.com/v0 as a STAC API which has Sentinel-2 (L1C, L2A, and L2A COGs), and Landsat will be added in the next couple weeks.
