On the map, these geometries are in red, and have the same geometries as the original geometries, so make sure to layer the failed ones on top! Comparing the failed geometries to the OSM base map and essentially the SharedStreets geometries, sometimes it is fairly obvious as to why the geometries did not match, but other times it is not clear. To better understand why some segments match better than others, it is suggested to conduct a deeper investigation into the parameters that the \`matchUrl\` is composed of. This notebook does not (currently) cover such an investigation. Some important observations: - if an OG segment is matched to an SS segment on one side of a median and not both sides, there is no way to identify that this happened without visual inspection - honestly, most of the time it is unclear at a glance why a segment was not matched, especially when it looks like it matches the OSM basemap underneath`3e:[] 38:{"id":"c5f77e272738f7d3","slug":"testing-observable-leaflet-and-sharedstreets","title":"testing observable, leaflet, and sharedstreets","thumbnail":"c83221ecd06217afc1d8c0824f42d80e8cb78d2269022c06f8275f187a10f43b","access_level":"public","create_time":"$D2018-08-21T14:46:08.327Z","update_time":"$D2018-09-07T02:34:56.322Z","view_time":null,"first_public_time":"$D2018-08-23T18:03:18.681Z","has_unpublished_edits":null,"fork":false,"stars":4,"starred":false,"owner":{"type":"team","id":"c62b66f2e9313b2c","login":"q-schen","name":"Q","avatar_url":"https://avatars-next.observableusercontent.com/20f7053e8b1dcd83a1290043912e5474a4579457f8201e49328a20f53e37ef73","tier":"starter_2024","bio":"Data Enthusiast | Masters Student @UWaterloo","followed_by_you":false,"follows_you":false},"version":691,"publish_version":691,"role":null,"authored":false,"authors":[{"type":"individual","id":"cfd08ed19ec148d8","login":"q-schen","name":"Q","avatar_url":"https://avatars-next.observableusercontent.com/20f7053e8b1dcd83a1290043912e5474a4579457f8201e49328a20f53e37ef73","tier":null,"bio":"Data Enthusiast | Masters Student @UWaterloo","followed_by_you":false,"follows_you":false}],"members":[{"type":"individual","id":"cfd08ed19ec148d8","login":"q-schen","name":"Q","avatar_url":"https://avatars-next.observableusercontent.com/20f7053e8b1dcd83a1290043912e5474a4579457f8201e49328a20f53e37ef73","tier":null,"role":"editor"}],"comments":[],"custom_thumbnail":false,"trashed":false,"lapsed":null,"subscribed":null,"forks":3,"collection":null,"type":"notebook","body":{"titling":"auto","title":"testing observable, leaflet, and sharedstreets","cells":[{"id":0,"value":"md`# testing observable, leaflet, and sharedstreets`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":100,"value":"md`## Setting up Leaflet`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","tool":"$undefined","providerMetadata":"$undefined","attachments":"$undefined","output":"$undefined","database":"$undefined"},{"id":61,"value":"md`\nTo include the Leaflet JavaScript, we have to use \\`require()\\` to pull it from https://unpkg.com, and assign it to the usual \\`L\\`.
