![]() ![]() These patches of moderate smoke are likely from wildfires in Canada as well as the western U.S. Northern Plains/Ohio Valley/Northeast U.S - Patches of moderate smoke was observed extending from North Dakota towards Ohio Valley, as well as off the coast of the northeast U.S. Cloud cover over much of the western, southwestern, and eastern Canada prevented further smoke analysis in these regions The largest of these, attributed to the significant number of wildfires in northwestern Canada and Alaska blanketed the northern half of Alaska and much of northern Canada. Within the much larger area of thinner density smoke were thicker batches. All of these wildfires were primarily responsible for a massive area of smoke which covered much of Canada, the northern half of Alaska, as well as much of the U.S., parts of the western Atlantic, the northern Gulf of Mexico, and northern Mexico. Another significant cluster of wildfires was present over west central Quebec to the southeast of Hudson Bay. ![]() United States/Alaska/Canada - Major widespread wildfire activity continues especially across western and northwestern Canada along with most of Alaska. ![]() Pan and zoom to see the entire lake area.Descriptive text narrative for smoke/dust observed in satelite imagery through Aug.On the Map tab in the Inquiry group, click the Locate icon and search for Crater Lake, Oregon.Start ArcGIS Pro and create a new project using the Map template.Make sure ArcGIS Spatial Analyst is enabled for ArcGIS Pro by checking your ArcGIS Online account.To complete the exercise in this tip, you will need access to ArcGIS Pro and ArcGIS Online. In this example, an aspect-slope map of the Crater Lake area in Oregon was created using the Terrain layer from ArcGIS Living Atlas of the World. Not only does this function make aspect-slope mapping faster and easier than ever before, it also does not require a new output dataset to be created (although you can save the raster layer file if you want).įollow the steps below to create an aspect-slope map in ArcGIS Pro. By doing this, the data is processed and displayed all in one step. You can create an aspect-slope map by using the Aspect-Slope function in ArcGIS Pro, which creates a raster layer that simultaneously displays the aspect and slope of a surface. Lighter hues (such as yellow) on northwest-facing slopes and darker hues (like purple) on southeasterly slopes give the impression of illumination on the terrain, which mimics the appearance of a three-dimensional landscape. The hues are brighter, or more saturated, on steeper slopes and duller on flatter slopes. In these maps, color hues such as red, green, and blue represent different directions. But first, here is a little background information about aspect-slope maps. In this tip, you will learn how to create an aspect-slope map quickly and easily in ArcGIS Pro. This is an aspect-slope map of the Crater Lake area in Oregon. ![]()
