![]() ![]() To view the aerial view of the current map location, you need to select an aerial year to display. However, you likely came here to view some historic aerial imagery, not to view maps, right? Maps are used for orientation, and we don't deviate from their utility. To zoom in, click on the plus, to zoom out, click on the minus. On the upper left side of the viewer content area are the zoom controls, indicated by the plus ( +) and minus ( -) sign. The text search box works for street addresses, cities, and even landmarks. Your map should now display with a center location in Fargo, North Dakota. see that text box in the upper left of the viewer with the text ' geo coordinates or street address'? Click on that text box and type Fargo, North Dakota, then click the ' go' button to the right, or press the key. Panning to Fargo, North Dakota from Yuma, Arizona might take awhile. That's all well and good you say, but the world is a big place. To move the map, drag it by clicking and holding down the left mouse button (or only mouse button if on a Mac.) With the mouse button pressed over the map, move the mouse and the map will pan. Otherwise, you will be dropped off in Tempe, Arizona where our headquarters is located. If you chose not to block your location, the default area will be your current location, or more specifically, the location of your Internet provider. To move this guide to the side of the screen, just click and drag the heading of the popup window to wherever you want it.Ĭhances are, you aren't interested in the area we present to you by default. You can keep it on the screen while you try our suggestions. Move the mouse around and try clicking on things. To help you scale this short (we hope) learning curve, we have compiled this list of common tasks. If you haven't worked any mapping websites, operation might not be obvious to you. Especially sites as unique as Historic Aerials. The color black is represented in a number of features including: boundaries, buildings, bridges, viaducts, tunnels, crossings, control data, monuments, dams, piers, break waters, foreshore and offshore features, mine symbols, roads, highways, trails, railroads, drive-in theatres, oil sumps, telephone lines, pipelines and wells. Although, no longer used the color (purple) found on the historical topo maps represent feature changes. The five (5) plates include vegetation (green), water (blue), public land survey lines and densely built-up areas (red), roads and buildings (black), contours and other elevation features (brown). There are five (5) color plates which were used in the film-based reproduction process. In fact, there are nearly 200 features represented by unique symbols and separated into color groups. The USGS Topographic Maps use symbols or colors to represent features, and this Topographic Map Key explains what they mean.Ĭontour lines are distinctive to the topographic maps but there are other features shown on the maps including buildings, water and vegetation. Interpreting the colored lines, areas and other symbols is necessary in using the topographic maps. The two previous conferences both attracted over 400 delegates from more than 40 nations and showcased over 100 papers, while also including ‘Spotlight on Innovation’ presentations.United States Geologic Service (USGS) Topographic Map Key (Legend) Given the heightened attention on the ‘climate emergency’, Breakwaters 2023 will place a big focus on how resilience and adaptability are being addressed by the maritime sector. The 2023 edition will cover the latest developments across maritime engineering topics from coasts to ports and waterfronts to breakwaters while focusing on the full spectrum of research and study, design, construction, and operations. Organisations represented in recent years include Boskalis Westminster, VolkerStevin, Balfour Beatty, BAM Nuttall, Costain, HR Wallingford, Arup, Atkins, Mott MacDonald, Jacobs, Arcadis, Environment Agency, and Local Government. Conference outcomes have translated into guidance documents and manuals defining industry standard practice for 40 years. Since 1982, Breakwaters authors, speakers and delegates have shaped the marine engineering sector, unveiling innovative technologies, assessing techniques, making formal recommendations, demonstrating best practice, and providing in-depth technical analyses. The next ICE Coasts, Marine Structures and Breakwaters will take place 25-27 April 2023 at the Marriott Hotel in Portsmouth, UK.
