These aerial images have a variety of uses including web based visualizations and to create derivative data such as buildings, roads and elevation models. They are viewed in many District web applications and made available as downloadable files. They can also be accessed as web services to integrate into your web apps. Use this viewer to compare a handful of imagery from past years. The District of Columbia typically captures aerial imagery every other year.</p>", "distribution": [{"@type": "dcat:Distribution", "accessURL": "https://opendata.dc.gov/apps/DCGIS::viewer-to-compare-dc-aerial-imagery", "format": "Web Page", "mediaType": "text/html", "title": "ArcGIS Hub Dataset"}, {"@type": "dcat:Distribution", "accessURL": "https://dcgis.maps.arcgis.com/apps/instant/compare/index.html?appid=89245889df06443994ba4c1e840f22ea", "format": "ArcGIS GeoServices REST API", "mediaType": "application/json", "title": "ArcGIS GeoService"}], "identifier": "https://www.arcgis.com/home/item.html?id=89245889df06443994ba4c1e840f22ea", "issued": "2024-07-15T17:29:50.000Z", "keyword": ["orthophoto", "aerial image", "washington dc", "district of columbia", "dc"], "landingPage": "https://opendata.dc.gov/apps/DCGIS::viewer-to-compare-dc-aerial-imagery", "license": "https://creativecommons.org/licenses/by/4.0", "modified": "2025-03-19T16:18:27.000Z", "publisher": {"name": "Office of the Chief Technology Officer"}, "spatial": "-77.1759,38.7870,-76.8933,39.0010", "theme": ["geospatial"], "title": "Viewer to Compare DC Aerial Imagery"}
