Digital Elevation Model

Satellite Imaging Corporation (SIC) provides orthorectified mono and stereo satellite maps that can be processed for visual of terrain conditions in a digital elevation model (DEM) from various stereo satellite sensors including the WorldView-4, WorldView-3, WordlView-2, and the latest Pleiades Neo satellite sensor at 30cm tri-stereo satellite maps for various applications. This DEM data can aid and support project planners, emergency operation managers, and logistics managers to plan field operations in a computer environment ensuring that the best terrain conditions and access is provided to achieve project objectives.

SIC processes satellite maps to produce digital elevation models to utilize and support engineering designs, construction activities, mining, pre-planning and lay-out of corridor surveys, land development, well sites, environmental monitoring, and geological surveys.

Pleiades-1 Tri-Stereo (1m) DEM

Satellite Map of Bingham Canyon Copper Mine, Utah, USA

The Pleiades Neo satellites can be programmed to collect tri-stereo maps for the production of high quality 1m-2m DEM for 3D urban and terrain modeling (DTM). The tri-stereo acquisition reveal elevation that would otherwise remain hidden in steep terrain or urban canyons in dense built-up areas.

There is a variety of DEM data available at various resolutions for developed areas and the suitability of this available DSM/DEM, or DTM data is produced on the project objectives and specifications. In remote regions around the world, where little or no DEM source data is available, the DEM can be produced from stereo satellite maps utilizing automatic DSM extraction or photogrammetric techniques (depending on the applications).

1m DTM for Suez Canal Expansion – Middle East Map of Suez Canal, Egypt

Stereo satellite maps are acquired over the area to produce an urban DEM model for feature extraction of building footprints and building heights such as the the above image of Dubai International Airport (DXB) showing ground navigation system and urban GIS data systems.

Quality DEMs are measured by how accurate the elevation is at each pixel and how accurately the morphology is presented. Several factors are important for a quality DEM:

Terrain roughness
Sampling density (elevation data collection method)
Grid resolution or pixel size
Interpolation algorithm
Vertical resolution
Terrain analysis algorithm

Common uses of models include:

Extracting terrain parameters
Volume calculations
Modeling water flow or mass movement (for example, landslides)
Creation of relief maps
Rendering of 3D visualizations
Creation of physical models (including raised-relief maps)
Orthorectification
Reduction (terrain correction) of gravity measurements
Terrain analysis in geomorphology and physical geography

FAQ’S

Frequently Asked Questions

How to find Geographic Coordinates in Google maps?

To find geographic coordinates in Google Maps, you can follow these steps:

Open Google Maps in your web browser or on your mobile device.
Search for the location you want to find the geographic coordinates for by entering the address, landmark, or name of the place in the search bar at the top of the page.
Once the location is displayed on the map, right-click (or long-press on mobile) the exact point on the map where you want to find the coordinates. This will open a small menu.
In the menu that appears, click on “What’s here?” or “What’s here? – Coordinates” option. On mobile devices, you may need to tap on the location marker first to reveal the menu options.
A small information box will appear at the bottom of the screen, displaying the latitude and longitude coordinates of the selected point. The coordinates will be shown in decimal degrees format.
You can click on the coordinates in the information box to expand it and see the coordinates in different formats, such as degrees, minutes, and seconds (DMS) or Universal Transverse Mercator (UTM) format.

How to Create a KML File in Google Earth?

To create a KML (Keyhole Markup Language) file in Google Earth, you can follow these steps:

Download Google Earth Pro and Open on your computer.
Navigate to the location or area you want to create a KML file for by using the search bar, zooming in/out, and panning on the map.
Customize the view and layers in Google Earth Pro to include the specific data or elements you want to include in your KML file. This can include placemarks, paths, polygons, overlays, images, and more.
Once you have set up the desired view and layers, go to the “Add” menu at the top of the screen and select the type of element you want to add (e.g., placemark, path, polygon, image overlay).
Follow the prompts to add the specific element and provide the necessary information, such as location coordinates, name, description, and any additional properties or styling options.
Repeat the previous step if you want to add more elements to your KML file.
After adding all the desired elements, go to the “File” menu and select “Save Place As.”
In the “Save Place As” dialog box, choose a location on your computer where you want to save the KML file.
Specify the name of the KML file, ensuring it has the .kml extension (e.g., myfile.kmL), you may need to select KML as GoogleEarth defaults to KMZ formats.
Click the “Save” button to save the KMZ file to the specified location on your computer.

What Are Satellite Imagery Raw Files?

Satellite map raw files refer to the unprocessed and unedited data captured by satellite sensors. These files contain the raw data received by the satellite sensors, including the reflected or emitted electromagnetic radiation from the Earth’s surface.

Satellite map raw files typically come in specialized formats specific to each satellite sensor or provider. These formats may include formats like GeoTIFF (georeferenced Tagged Image File Format) or ENVI (Environment for Visualizing Images). The raw files preserve the original sensor readings, which can include various spectral bands, radiometric information, and geometric parameters.

Raw files require processing to convert them into usable formats, such as georeferenced images or digital elevation model(DEM). Processing steps may involve radiometric and geometric corrections, atmospheric compensation, calibration, orthorectification, and mosaicking, among others.

Once processed, raw files can provide valuable information for various GIS data applications, including 3D terrain maps, agriculture production maps, vegetation maps, and disaster maps.

How To Download Satellite Maps in FTP

To download satellite maps from an FTP (File Transfer Protocol) server, you can follow these general steps:

Obtain the FTP server information: Get the FTP server details from the satellite maps provider or the source you are accessing. This includes the FTP server address, username, password, and potentially the directory path to the imagery files.
Choose an FTP client: Select an FTP client software or application that allows you to connect to the FTP server and perform file transfers. Some popular options include FileZilla, WinSCP, Cyberduck, or the built-in FTP functionality of certain web browsers.
If you are unable to download an FTP client due to software locks, Windows has a built in FTP Protocol that can be accessed by copying the URL of the FTP server in your Windows File Explorer.
Depending on the method to connect to the FTP, you will need credentials including a Username and Password to access these file.
Most FTP clients will allow you to Copy and Paste or Drag and Drop the files from the client window to your local files.

Remember to comply with any terms and conditions associated with the satellite map data, including usage restrictions, licensing agreements, and any attribution requirements specified by the provider.
