1:24,000 US Topo Texas and Louisiana Maps

Last Update: Varies
Source: U.S. Geological Survey (USGS)

The USGS US Topo map series at 1:24,000 is available for all of CONUS and incorporates USNG coordinate numbering around the border of each map.  To obtain US Topos for the Texas and Louisiana coast line where Hurricane Laura made landfall (or anywhere else in CONUS), use the following steps:

  1. Use the link at the bottom of this section to proceed to the USGS US Topo download feature of The National Map,
  2. When the download viewer opens, zoom in on an area of interest until the US Topo edge lines appear,
  3. Use the place icon or draw rectangle feature in the left side bar to identify the desired sheet,
  4. A set of boxed windows will open on the left side of the screen – look for the US Topo window and click “results,”
  5. When this window opens, click “Download” to download the desired US Topo to your computer.

1:6,000 Texas and Louisiana Coastal Mapbooks

Last Update: September 2017
Source: National Geospatial-Intelligence Agency (NGA)

Each map in this series will print on 8.5 x 11 conventional paper an area which approximates ten (10) football fields square (1,000m x 1,000m). This is a much more detailed view than is available using the Delta State University maps above and would typically be used for dense urban areas.

To obtain the maps, use the following steps:

  1. Click the link below this section,
  2. After the viewer opens, zoom in on an area of interest (due to the amount of data available, it may take as long as 3 MINUTES for the areas with available mapbooks to appear), zoom in on an area of interest,
  3. Decide whether you want an entire county worth of maps, or a specific area,
  4. As appropriate for the decision made in step 3, ensure that ONLY one of two boxes is checked: “Texas LA Disaster Single Page” or “Texas LA Disaster by County (zip file)“,
  5. Ensure the “US National Grid” box is CHECKED and that “Short Duration Hazards – Warnings” and “Recent Weather Radar Imagery” are UNCHECKED,
  6. Place your cursor over the grid square of interest and then left click (Note – if you attempting to retrieve single page(s), you must be zoomed in close enough to be seeing the 1000 meter grid squares),
  7. A pop-up box will then open,
  8. Use the “Select to download Atlas – More Info” hyperlink to download desired map(s).

1:25,000 Texas Mapbooks 

Last update: September 1, 2017

Delta State University

Each link below downloads a zip file containing individual mapbook pages at 1:25,000 for the named Texas coast and eastern counties (Texas County map). As appropriate, individual pages can then be printed on conventional 8.5 x 11 paper by following the instructions for ensuring accuracy of scale found at the bottom of each page.  These atlases work best for generalized views of rural and suburb areas because at 1:25:000 scale, each page will show a larger area than the 1:6,000 scale atlas pages offered by NGA in the above section.
