Recently, the GEOGLOWS streamflow service was upgraded from v1 to v2<\/a>. GEOGLOWS provides global river discharge forecast for 7 million river reaches for the next 10 days in 3-hour intervals. GEOGLOWS is a comprehensive service for the water resources<\/a> and disaster response<\/a> communities, but as it was developed globally, it does not include local river names. As part of the recent upgrade, the GEOGLOWS service in Living Atlas<\/a> now displays river names from OpenStreetMap (OSM)<\/a>.<\/p>\n

The river names from OSM<\/a> are obtained dynamically, meaning that GEOGLOWS will always display the latest information available. If missing river names in OSM are added, those will show up in the GEOGLOWS service. In this blog, I\u2019ll show you how information from OSM can be included in any layers using ArcGIS Arcade<\/a> expressions such as in GEOGLOWS.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2489012,"id":2489012,"title":"OSM River Names in GEOGLOWS","filename":"OSM_names_animation-2.gif","filesize":3652149,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/OSM_names_animation-2.gif","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/mapping\/mapping\/augmenting-geoglows-with-river-names-from-openstreetmap\/osm_names_animation-3","alt":"","author":"9412","description":"","caption":"","name":"osm_names_animation-3","status":"inherit","uploaded_to":2482622,"date":"2024-09-13 15:14:30","modified":"2024-09-13 15:15:28","menu_order":0,"mime_type":"image\/gif","type":"image","subtype":"gif","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":1684,"height":656,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/OSM_names_animation-2-213x200.gif","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/OSM_names_animation-2.gif","medium-width":464,"medium-height":181,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/OSM_names_animation-2.gif","medium_large-width":768,"medium_large-height":299,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/OSM_names_animation-2.gif","large-width":1684,"large-height":656,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/OSM_names_animation-2-1536x598.gif","1536x1536-width":1536,"1536x1536-height":598,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/OSM_names_animation-2.gif","2048x2048-width":1684,"2048x2048-height":656,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/OSM_names_animation-2-826x322.gif","card_image-width":826,"card_image-height":322,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/OSM_names_animation-2.gif","wide_image-width":1684,"wide_image-height":656}},"image_position":"center","orientation":"horizontal","hyperlink":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/OSM_names_animation-2.gif"},{"acf_fc_layout":"content","content":"

Pop-up Configuration<\/h2>\n

In the map viewer, we (1) select the GEOGLOWS layer, (2) open the pop-up panel, (3) make sure pop-ups are enabled, and (4) create a custom attribute expression. This attribute expression can be used within the (5) pop-up text.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2489052,"id":2489052,"title":"GEOGLOWS_pop-up","filename":"GEOGLOWS_pop-up.png","filesize":327837,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/GEOGLOWS_pop-up.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/mapping\/mapping\/augmenting-geoglows-with-river-names-from-openstreetmap\/geoglows_pop-up","alt":"","author":"9412","description":"","caption":"","name":"geoglows_pop-up","status":"inherit","uploaded_to":2482622,"date":"2024-09-13 15:17:53","modified":"2024-09-13 15:17:53","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":752,"height":332,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/GEOGLOWS_pop-up-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/GEOGLOWS_pop-up.png","medium-width":464,"medium-height":205,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/GEOGLOWS_pop-up.png","medium_large-width":752,"medium_large-height":332,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/GEOGLOWS_pop-up.png","large-width":752,"large-height":332,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/GEOGLOWS_pop-up.png","1536x1536-width":752,"1536x1536-height":332,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/GEOGLOWS_pop-up.png","2048x2048-width":752,"2048x2048-height":332,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/GEOGLOWS_pop-up.png","card_image-width":752,"card_image-height":332,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2024\/09\/GEOGLOWS_pop-up.png","wide_image-width":752,"wide_image-height":332}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

Attribute Expression<\/h2>\n

We configure a custom attribute expression that can be added into the pop-up. The attribute expression includes three general steps: (1) intersect the\u00a0 GEOGLOWS river segments with the OSM Waterways, (2) filter the intersected river segments, and (3) select the river name and handle nulls.<\/p>\n

1. Intersect GEOGLOWS river segments & OSM Waterways<\/h3>\n

To get the OSM river name in the pop-up, we intersect the GEOGLOWS feature Geometry($feature)<\/span><\/code>with the OSM waterways layer OSM_waterways_lyr<\/span><\/code>:<\/p>\n

var <\/span>rivers_intersect<\/span> = Intersects(Geometry($feature)<\/span>, OSM_waterways_lyr);<\/span><\/code><\/p>\n

In which the OSM_waterways_lyr<\/code> can be obtained with the FeatureSetByPortalItem<\/em><\/a> function and the OSM Waterways item ID:<\/p>\n

var<\/span> OSM_waterways_lyr = FeatureSetByPortalItem(Portal(\"https:\/\/www.arcgis.com\"<\/span>),
\nOSM_Waterways_id, 0<\/span>, [\"name\"<\/span>, \"name_en\"<\/span>], true<\/span>);<\/code><\/div>\n
<\/div>\n"},{"acf_fc_layout":"content","content":"

 <\/p>\n

The additional parameters specify the layer ID number (0<\/code>), the required fields ([\"name\", \"name_en\"]<\/code>), and if the geometry is returned (true<\/code>).<\/p>\n

The OpenStreetMap (OSM) Waterways<\/a> are divided into items per continents due the size of the geodatabse. The specific IDs for each continent are:<\/p>\n
