After you download an area, use the Google Maps app just like you normally would. If your internet connection is slow or absent, your offline maps will guide you to your destination as long as the entire route is within the offline map.
Offline maps that you downloaded on your phone or tablet must be updated before they expire. When your offline maps expire in 15 days or less, Google Maps tries to update the area automatically when you're connected to Wi-Fi.
Included in The National Map are the latest elevation data from the 3D Elevation Program (3DEP), surface water data from the National Hydrography Datasets (NHD), and place name data from the Geographic Names Information System (GNIS). In addition, The National Map provides continuously-updated, seamless datasets for recreational trails, roads, boundaries, structures, land cover, and imagery.
The National Map also serves as the data source for modern USGS topographic maps such as US Topos and OnDemand Topos. US Topo maps and scans of historic USGS topographic maps are also available as a part of The National Map.
Data and products from The National Map can be used by government, industry, academia, as well as the public, in support of geologic mapping, natural hazard planning, natural resource conservation, emergency management, recreation, and many, many other applications.
The U.S. Geological Survey's National Geospatial Program developed the GNIS in support of the U.S. Board on Geographic Names as the official repository of domestic geographic names data, the official vehicle for geographic names use by all departments of the Federal Government, and the source for applying geographic names to Federal electronic and printed products.
topoBuilder is a public web application released by the National Geospatial Program that enables users to request customized USGS-style topographic maps, known as an OnDemand Topo, that utilize the best available data from The National Map.
While I was using UMD myself at times I created my tutorial, I nowadays only use Global Mapper, as it allows you to download layers just the exact size of the map and you can export them just fitting on the square you defined, projected in UTM and automatically stitched together. Furthermore, there are far more layers accessible on the web than UMD allows you. Just look for WMS/TMS layers on google and you will find lots of data for your area which can be easily added to Global Mapper.
For satellite images, I use "World Imagery" provided by ESRI (without watermark ofc) but in general I think that it is not a too good idea to use high detail satmaps at all, as you can never recreate the detail displayed on the image (expect for large landscapes without buildings maybe). It might look good at height but silly on the ground. Detail level as on Chernarus satmap is enough.
What I know find quite useful is "World Topographic Map", as the terrain features there are represented in one color and not so detailed like on satellite images, which means you can easily separate them and fill them with (Chernarus/Takistan)-textures as satmask or with colors for texture mask.
If you want to get geo-referenced images of any zoom level, with the GPS stuff in the file, use this program: Global mapper can import OziExplorer data. When downloading the image, just select an area bigger than what you think you need, and use global explorer to export both the .xyz and a .png. Best of all, Terra Incognita is free!
Ultimate Maps Downloader allows you to download tiled map images from different online maps providers, such as Google, OpenStreet, Yahoo!, Bing and ArcGIS, to combine them into larger maps.
The application has a modern-looking tabbed interface. The working area is a map, on which you can define areas at different zoom levels. Once you have determined the exact map region you need, you can proceed to download it. Actually downloading the selected area very easy, and you can even define the exact geographical coordinates for the two opposite corners so that the downloaded area remains rectangular.
Other important options include selecting the servers you wish to download the maps from and choosing the zoom levels from a list of 20. In addition, you can select the image format and the output folder as well as decide if you want to combine the different tiles into a larger image. Similarly to Google Earth, you can enter the name of a location and this program will automatically find it and mark it with a crosshair. Moreover, you can mark given locations with customized icons. An important feature is that this application can create ESRI World files (JGW) that can be imported into professional mapping software like Global Mapper and ER Mapper.
With offline maps in iOS 17 and later, you can use Maps for information and navigation even when you don't have a Wi-Fi or cellular connection. Offline maps include details like hours and ratings on places, turn-by-turn directions for driving, walking, cycling, or riding transit, and estimated arrival times.
Offline maps do not sync across your devices. Offline maps are only available in select areas. An offline map for a specific region is not intended for use in all regions. Features vary by country and region.
I have a strong dislike for the offline maps systems in most other mapping apps. Typically they operate on some variant of establishing a rectangular area you want the downloaded maps to cover and then adding it to a list of offline map sets.
Thinking along those lines my first thought was to add an overlay to a regular map which has buttons for downloading a given map tile (and all its children tiles). The user could get browse around to wherever they want to explore and then cache or uncache whatever segments they chose.
So instead of having a fully zoomable, multi-level download button system. I instead switched to a fixed geographic size block system. Where a particular download button always reflects the same area of the earth.
The first question I had to answer was how large this area should be. I thought a good guide would be large enough to accommodate the Mist Trail in Yosemite. This is an area of around 2,000 acres. Big enough to have a proper explore but not unwieldy so.

The National Flood Hazard Layer (NFHL) is a geospatial database that contains current effective flood hazard data. FEMA provides the flood hazard data to support the National Flood Insurance Program. You can use the information to better understand your level of flood risk and type of flooding. The NFHL can also be used in place of the FIRM for NFIP purposes with appropriate care.
The NFHL is made from effective flood maps and Letters of Map Change (LOMC) delivered to communities. NFHL digital data covers over 90% of the U.S. population. New and revised data is being added continuously. If you need information for areas not covered by the NFHL data, there may be other FEMA products which provide coverage for those areas.
In the NFHL Viewer, you can use the address search or map navigation to locate an area of interest and the NFHL Print Tool to download and print a full Flood Insurance Rate Map (FIRM) or FIRMette (a smaller, printable version of a FIRM) where NFHL data exists. Technical GIS users can also utilize a series of dedicated GIS web services that allow the NFHL database to be incorporated into websites and GIS applications. For more information on available services, go to the NFHL GIS Services User Guide.
Pending Flood Insurance Rate Map (FIRM) Databases are scheduled to be adopted by the local government and become effective within six months. This is the final step in the process before new flood hazard data becomes effective. Pending FIRM Databases have been designated final by the Letter of Final Determination issued to community officials. However, they do not officially define the minimum requirements for National Flood Insurance Program (NFIP) purposes until they become effective at the end of the six-month adoption and compliance period.
They are published in the Pending NFHL as soon as possible to give community officials, lenders, and the public time to prepare for new official data. Pending data may include new or revised Flood Insurance Rate Maps (FIRM), Flood Insurance Study (FIS) Reports and FIRM Databases. If pending data is available for your community, you can view it and compare it with existing data on the Flood Map Changes Viewer.
The Flood Hazard and Risk Data Viewer shares a variety of flood hazard and risk data from FEMA. This viewer provides a single location to view a large inventory of data that represents both current and future flood conditions to help users understand their flood hazard and other risk-related information. Some flood hazard and flood risk data produced by FEMA define minimum requirements for the National Flood Insurance Program (NFIP). This viewer includes these required NFIP data and includes other data showing current and potential future flood hazard and risk. This provides users access to more complete flood hazard data. FEMA also uses this viewer to provide communities an opportunity to comment on early drafts of flood hazard data.
