#SharedWatersGIS - is an initiative dedicated to mapping and delivering GIS-ready geospatial products and data for the transboundary water geography shared between Canada and the United States, as exemplified by the International Joint Commission's updated ArcGIS Online platform featuring harmonized watershed datasets and more. - ijc.org/en Discover the International Joint Commissions' AGOL Platform ijc.maps.arcgis.com/

New on IJC.maps: a simple yet powerful Esri app that maps NASA/NOAA VIIRS daily thermal hotspot detections (375 m) for near real-time wildfire awareness—especially useful in shared U.S.–Canada basins where impacts cross borders.

Leveraging EPA 303(d) Impaired Waters Data for Binational Basin Management In transboundary watersheds, water quality doesn't stop at the border. EPA's Section 303(d) lists identify U.S. waters impaired by pollutants (e.g., nutrients, mercury, pathogens) needing TMDLs — valuable for spotting risks that flow north into Canada. Key opportunity: Integrate these GIS layers with IJC's harmonized datasets in the Binational Geospatial Platform or Red River Basin Atlas to: • Visualize cross-border impairment patterns • Prioritize joint monitoring & restoration • Support nutrient reduction strategies Example: Many River segments are 303(d)-listed for nutrients — harmonizing with Canadian data could enhance binational flood quality decision-making.

🌎 New from @SharedWatersGIS The International Joint Commission is excited to release our first suite of Esri Atlas–powered products. Here we are focused on the Shared Waters of the Red River Basin of the North - as an example 🇨🇦🇺🇸 ijc.maps.arcgis.com/apps/ins… What is the Esri Atlas? Esri Atlas is a curated collection of authoritative, ready-to-use geospatial content—basemaps, imagery, demographics, hydrology, and environmental data—designed to support rapid insight and informed decision-making. Why this matters for the Red River Basin By leveraging Esri Atlas content, the IJC can quickly assemble a basin-wide, transboundary view of hydrology, land cover, infrastructure, and environmental context—without duplicating data—allowing Boards and partners to focus on analysis, coordination, and action. And this is just the beginning… The IJC is now fully leveraging Esri Atlas products across other shared basins, including: • St. Croix River • Souris River • Rainy–Lake of the Woods Each basin benefits from the same authoritative foundation, tailored to its unique geography, governance, and management needs. Coming soon @SharedWatersGIS will be rolling out integrated basin products that combine Esri Atlas content with IJC-curated data, real-time services, and purpose-built applications—designed specifically for transboundary water governance. Stay tuned. Shared waters deserve shared insight. @MnPCA @RedRiverBasin #SharedWatersGIS #EsriAtlas #TransboundaryWaters #RedRiverBasin #IJC #GIS #SharedBasins @SharedWatersGIS @IJCommission @Esri @EsriLivingAtlas @EsriCanada

Nouveauté de @SharedWatersGIS La Commission mixte internationale exploite pleinement les couches groupées (Group Layers) dans notre environnement AGOL afin de gérer et de diffuser des images lourdes de manière intelligente et efficace. Qu’est-ce qu’une couche groupée? Une couche groupée rassemble plusieurs couches connexes — imagerie, vecteurs, séries temporelles — dans un seul ensemble organisé. Cela nous permet d’activer ou de désactiver du contenu, de contrôler la symbologie et d’optimiser la performance sans dupliquer les données ni augmenter l’espace de stockage. Grâce au nouveau Service d’imagerie Sentinel-2 sur la couverture terrestre à 10 m / séries temporelles, la CMI a maintenant créé : • Des couches groupées homogènes pour chaque bassin transfrontalier, et • Une application Canada–États-Unis de type swipe pour explorer les changements de couverture terrestre de part et d’autre de la frontière. En utilisant les couches groupées, nous pouvons manipuler et organiser une imagerie complexe sans surcharger le stockage infonuagique. Et en surveillant l’utilisation à l’aide des résumés d’éléments et de couches AGOL, nous pouvons déterminer stratégiquement quels jeux de tuiles d’imagerie traiter localement pour répondre aux besoins opérationnels et de performance. Prochaine étape : la Commission commencera à développer des statistiques zonales afin de quantifier l’évolution de la couverture terrestre dans le temps — une avancée essentielle pour la communauté de la Commission. Des données plus intelligentes. Une empreinte plus légère. Une meilleure compréhension de nos eaux partagées. 🌊🛰️ #SIG #EauxPartagées #Esri #Sentinel2 #CMI #Géospatial #ArcGISOnline Transfrontalier: ijc.maps.arcgis.com/apps/ins… Comparer: experience.arcgis.com/experi… The Living Atlas: ijc.maps.arcgis.com/apps/map…

New from @SharedWatersGIS The International Joint Commission is taking full advantage of Group Layers in our AGOL environment to manage and deliver heavy imagery in smart, efficient ways. What are Group Layers? A Group Layer bundles multiple related layers—imagery, vectors, time series—into a single, organized package. This lets us toggle content, control symbology, and streamline performance without duplicating data or inflating storage. Using the new Sentinel-2 10m Land Cover / Time-Series Imagery Service, the IJC has now built: • Seamless Group Layers for every transboundary basin, and • A Canada–U.S. swipe app for exploring land-cover change across the boundary. By leveraging Group Layers, we can manipulate and curate complex imagery without over-taxing cloud storage. And by monitoring usage via ArcGIS Online Item & Layer Summaries, we can strategically decide which image tiles to process locally for performance and product needs. As a next step, the Commission will start to develop Zonal Statistics to quantify land-cover change over time; a critical step forward for the Commission’s community. Smarter data. Lighter footprint. Better shared-waters insight.
