Example: Use of Elevation Finder for Flood Risk Assessment.

Imagine you are a disaster management expert in New Orleans, Louisiana. You need to know flood risks in low-lying neighborhoods while making a disaster management plan. By identifying areas with low elevation as compared to sea level , you can make effective evacuation routes and strategically place emergency shelters on higher grounds with maximum effectiveness.

Elevation Map Application User Guide:

We will go through it step by step to use this elevation map application to answer your question: what’s my current elevation on the map using my current geographic location

Step 1: Locate Yourself on Map Using Elevation Finder Application:

There are two options to locate yourself on map to get the elevation of your desired location. Let’s talk about “My Current Location” first. At top of the application in menu bar there is a green button with “My Location” text. Press it and browser will ask to allow to read your current location. Allow the browser then the map will be zoomed to your current location.

Step 2: Find Elevation on Map

Now we are on the location where we can find the altitude on map. Place mouse pointer on map where elevation information is required and click on map. A popup with relevant information will be appeared as shown in the screenshot below.

Base Map Switcher

An additional functionality for users to enhance user experience, we introduce basemap switcher. With the help of basemap switcher user can easily change view from streetmap to satellite or topographic map.

Before the technology was evolved, only special workers with expensive tools could find the exact height of a place above sea level. Now, a person with internet can use a website to get that same information. These websites help people who walk outside, people who build things, and people who just want to know.

How elevation websites work

Specialized web applications do not measure anything by themselves. They usually connect to big data repositories called Digital Elevation Models. When you click anywhere on a web map, the app code transform that click using code to find the spot's location (latitude and longitude). Then a request is sent to the server to send back the elevation for that particular lat long.

Where the numbers come from

Different numbers have different levels of detail.

  • SRTM data came from space shuttles. It shows height in squares that are 30 meters wide. That is good for large areas.
  • LiDAR data comes from airplanes. It shows small details down to one centimeter. That is very precise.
  • Bathymetry data shows depth under water instead of height above water.

A problem to watch for

Each tool has a resolution. Resolution means the size of the smallest area the tool sees as one flat piece. If a tool uses 30 meter resolution, it cannot tell if one small part of that square is higher than another part. If you click near a sharp drop, the tool may give you an average number instead of the true top or true bottom.

What comes next

Because of new web technology, elevation tools now show land in three dimensions. A person can turn the view and tilt the view. The person can see the shape of the land. This change makes geographic information easier to understand. Numbers become an image you can move around.

People use these tools to plan a walk in the mountains or to check the tilt of a piece of land. What used to require special workers is now available to everyone.

What is the primary data source to get elevation by clicking on map?

Ans: When you click on a map to get the elevation using this app on a specific point, the primary data source used is Digital Elevation Model (DEM).

Real-world examples of DEMs used:

  • SRTM (Shuttle Radar Topography Mission) – covers most of the world at ~30-meter resolution.
  • ASTER GDEM – another global dataset, also ~30 meters.
  • USGS NED (National Elevation Dataset) – higher resolution for the U.S. (like 1/3 arc-second, ~10 meters).
  • LiDAR-derived DEMs – very high resolution (1 meter or less), but only available for limited areas.
    •

    So, in short: DEM is the source. The map just reads from it when you click. No magic — just smart grids and averaging!

         How is a click coordinate converted into an elevation value?

    Ans: When you click, the map knows your click’s screen coordinates (X, Y in pixels).
    It then converts those into geographic coordinates (latitude and longitude) based on the map’s current zoom level and projection.

    Step 2: Find which DEM cell contains that point
    The map now has a lat/lon, like (40.7128°N, -74.0060°W).
    The DEM is a grid where each cell has known lat/lon boundaries.
    The software figures out: Which grid cell does this lat/lon fall into?

    Example:
    If the DEM cell covers from 40.7125°N to 40.7130°N in latitude, your click at 40.7128°N falls inside that cell.

    Step 3: Read the cell’s elevation (or interpolate)
    Now it gets clever:

  • If your click lands exactly on a cell’s center → just return that cell’s stored elevation. Easy.
  • But most clicks fall somewhere between cell centers → the system performs bilinear interpolation.
    •  What’s bilinear interpolation in simple terms?
    Imagine the four surrounding DEM cells (northwest, northeast, southwest, southeast). Each has a known elevation. Your click point is somewhere between them.
    The software:
    • First averages the two west cells vertically → a “west estimate”
    • Then averages the two east cells vertically → an “east estimate”
    • Then averages those two results horizontally (using distance weighting) → final elevation
    It’s basically a smooth weighted average of the four nearest known elevations.

    Step 4: Return the result
    After the math, you see a number on screen:
    “Elevation: 234 meters”
    All in milliseconds—faster than you can blink.

         What determines the accuracy of the elevation result?

    Ans: Accuracy is primarily dictated by spatial resolution. For example:

  • 30-meter resolution: One elevation value is assigned to a 30m x 30m square.
  • 1-meter resolution: Captured via LiDAR, providing much higher precision. If you click in the middle of a 30m grid cell that covers both a cliff edge and a valley, the returned value is an average of that area.
    •

    In other words: the finer the DEM resolution, the more accurate the elevation retrieval for micro-terrain features. Global DEMs like SRTM (30m) are suitable for regional analysis, while high-res LiDAR captures subtle changes.

    Additional nuance: vertical accuracy also matters (RMSE), but for click-based queries, horizontal resolution is the main factor.

         Does clicking on a building return the ground or roof height?

    Ans: This depends on whether the tool uses a DEM or a DSM (Digital Surface Model).

  • DEM/DTM: Filters out vegetation and man-made structures to show the bare earth.
  • DSM: Includes the "tops" of everything, meaning a click on a skyscraper would return the roof's elevation.
    •

    Most generic web apps default to DEM (bare earth) for terrain profiles, but specialized mapping tools may offer a DSM layer. Always check the metadata: if the source mentions “first return” or “canopy model”, it’s a DSM. If it says “bare earth” or “DTM”, you’re getting ground elevation.

    Practical note: In urban environments, using a DSM for click elevation gives you building heights, while a DEM gives you street level.

         Summary: DEM is the primary source. Click → geographic coordinates → locate DEM cell → bilinear interpolation → elevation value. Accuracy depends on resolution (30m vs 1m LiDAR). Ground vs roof? DEM (bare earth) vs DSM (top surface).
