Lake Sulunga, also known as Bahi Swamp, is located in Central Tanzania, approximately 45 km west of the capital of Dodoma. It is a fertile oasis in the otherwise semi-arid and drought-prone region.This viewer uses the swipe tool to compare the standard extent of Lake Sulunga to its extent during the El-Niño floods from March - May 2016.Use the Layer List at the top left of the viewer to toggle on/off the extent of the lake during the severe drought that was experienced around the Dodoma/Singida region in the previous year. The Bookmarks zoom to the two key settlements at the south west of the lake that were adversely affected by the floods.The layers in the web map are from the Multispectral Landsat image service from the ArcGIS Living Atlas of the World covering the landmass of the World, centered on Lake Sulunga, Tanzania. The NIR, IR1 and R (564) renderer has been applied, resulting in a false colour image where land appears in shades of browns, oranges and greens, and water appears in shades of blue. Moisture differences are distinctly identified where wetter soil appears darker because of the infrared absorption capabilities of water.

This viewer is available through CT ECO, a partnership between CT DEEP and UConn CLEAR. DescriptionThe Elevation Viewer contains statewide bare earth elevation. The elevation layers are pixels derived from a Lidar point cloud. The Hillshade, Shaded Relief, Slope, and Aspect are all part of the viewer and are different ways of viewing the bare earth elevation. The Viewer also contains contours, older elevation layers, and reference layers like parcels, aerial imagery, watersheds, and impervious surface. All about elevation on CT ECOLidar FAQ UseTo use the viewer, zoom in and then use the Layer List (upper right) to turn on and off layers (remember to turn OFF the ones above on the list or they will hide layers below) to compare and explore the area. The swipe tool (lower left) is a fun way to compare two datasets, especially aerial imagery with an elevation layer like hillshade or slope. Be sure at least two items are checked on in the layer list and use the swipe tool to compare. Refer to Viewer Help for more details and tips. Tipslidar points can reach the ground through tree canopy and exceptional at "seeing" features like stone walls that are not easily visible on aerial imagery"dynamic color" services means that the full range of colors is always displayed no matter what the viewing extentlidar points can also be used to create surfaces, which are different from bare earth elevation shown in the Elevation ViewerCT ECO has a 3D Lidar Point Viewer that contains points that have been colored based on summertime aerial imagery

About the dataLand use land cover (LULC) maps are an increasingly important tool for decision-makers in many industry sectors and developing nations around the world. The information provided by these maps helps inform policy and land management decisions by better understanding and quantifying the impacts of earth processes and human activity.The Annual NLCD product is available courtesy of the USGS. The data is a confluence of methodologies from past land cover projects together with modern innovations in geospatial deep learning technologies to create the next generation of land cover and land change information. About the appOne of the foremost capabilities of this app is dynamic change analysis. The app provides dynamic visual and statistical change by comparing annual slices of the NLCD Land Cover data as you explore the map.Overview of capabilities:Visual change analysis with either ‘Animate Mode" or "Swipe Mode"Dynamic statistical change analysis by year, map extent, and classFilter by selected land cover classImagery mode for visual investigation and validation of land coverSelect imagery renderings (e.g. SWIR to visualize forest burn scars)

This map is a new construct that incorporates existing geologic maps where prior mappers had adequate ground control, and new interpretations based on drill hole, geophysical, and unpublished data where they did not. The interpretation differs significantly from previous maps to reflect new data and accommodate scale. It portrays our current geologic understanding of the temporal and geographic distribution of units within major Precambrian terranes and of the Phanerozoic strata. The western part of the mapped Precambrian terrane is inferred largely from geophysical maps, anchored locally by drilling. In many places, contacts are drawn between units of the same or similar apparent rock type (and same unit label); these are recognized as geometrically distinct, though geophysically or lithologically similar. Digital files corresponding to this map allow removal of Cretaceous, Paleozoic, and some parts of Mesoproterozoic strata to reveal an interpretation of the underlying Precambrian bedrock.The swipe tool displays S-22, Geologic Map of Minnesota, Precambrian Bedrock Geology. It portrays an interpretation beneath Phanerozoic (Paleozoic and Mesozoic) strata inferred from geophysical maps and drill core. Bedrock map includes faults, form lines inferrred from geophysical data, dike locations and types, and geologic interpretations based on geophysics of the area of Minnesota that extends into Lake Superior.
