![]() To compare change over time, scans of legacy USGS topo maps, some dating back to the late 1800s, can be downloaded from the USGS Historical Topographic Map Collection. The TIGER database contains all geographic features - such as roads (more than 6.3 million miles), railroads, rivers, and legal and statistical geographic boundaries - needed to support the Census Bureau’s data collection and dissemination programs. The USGS recently released US Topo maps for Wisconsin, Iowa and Kansas which were the first set of states to feature TIGER data. These new US Topo maps replace the second edition US Topo maps and are available for no-cost file download from The National Map, the USGS Map Locator & Downloader website, and several other USGS applications. The US Topo map improvement program has entered its third, three-year cycle of revising and updating digital US Topo quadrangles. Fish & Wildlife Service National Wetlands Inventory, along with the continued incorporation of “crowdsourced” trail data from the International Mountain Bike Association. Other important additions to the new US Topo maps for Texas and Oklahoma are the integration of wetlands layers using data from the U.S. “Our agency deployed the US Topo digital maps to our field personnel across the state.” “The US Topo digital maps are a great public resource to provide authoritative, robust maps to emergency management field personnel and first responders when response time matters”, said Michael Ouimet, Critical Information Systems Manager for the Texas Division of Emergency Management. Census Bureau’s Topologically Integrated Geographic Encoding and Referencing (TIGER) road data. One of the main improvements is the inclusion of the U.S. Index and on-line searches for ordering NOAA, National Ocean Service (NOS) Bathymetric and Fishing Maps from the NOAA National Centers for Environmental Information (NCEI) and collocated World Data Service for Geophysics. Popular fish species in this lake include Alligator gar.New US Topo maps for Texas and Oklahoma are now available in the USGS Store for free download. 1:1,000,000 scale maps compiled from 1:250,000 scale bathymetric maps. ![]() ![]() The Livingston Dam, constructed across the Trinity River about 7 miles (11 km) southwest of the city of Livingston is 2.5 miles (4 km) in length and has an average depth of 55 feet (17 m). The lake is the second-largest lake located wholly within the state of Texas (only the Sam Rayburn Reservoir is larger). Lake Livingston was built and is owned and operated by the Trinity River Authority (TRA) of Texas under contract with the City of Houston for water-supply purposes. Lake Livingston is a reservoir located in the East Texas Piney Woods. Have more questions about the Nautical Chart App? Ask us. Now i-Boating supports Fishing Points in Livingston Reservoir. Autopilot support can be enabled during ‘Goto WayPoint’ and ‘Route Assistance’. Lake navigation features include advanced instrumentation to gather wind speed direction, water temperature, water depth, and accurate GPS with AIS receivers(using NMEA over TCP/UDP). Fishing spots and depth contours layers are available in most Lake maps. The Livingston Reservoir Navigation App provides advanced features of a Marine Chartplotter including adjusting water level offset and custom depth shading. The fishing maps app include HD lake depth contours, along with advanced features found in Fish Finder / Gps Chart Plotter systems, turning your device into a Depth Finder. With our Lake Maps App, you get all the great marine chart app features like fishing spots, along with Livingston Reservoir depth map. Livingston Reservoir fishing map is available as part of iBoating : USA Marine & Fishing App(now supported on multiple platforms including Android, iPhone/iPad, MacBook, and Windows(tablet and phone)/PC based chartplotter.).
