Height and slope of a plot

How high a plot sits above sea level, how steeply it slopes and which way the ground falls, with the maximum building height the airport rules allow there.

Free to run. Sign in once and use it as often as you need.

What we need

One thing at a time. Fill it in and press Run.

Drop a pin, paste a Google Maps link, or use your location.

The answer

From the register, with its date and source.

Nothing run yet. The answer appears here with everything this mini adds:

  • Slope as a grade and a direction, so drainage and fill can be judged
  • The neighbouring heights north, south, east and west
  • The airport height cap at the same point, read in the same run

How this works

What it reads, what it needs, and how to read the answer.

What it does

Elevation and slope decide how a plot drains and how much filling a build needs, and low ground near the coast is where flood risk starts. This mini reads the terrain model at a pin.

What you give it

A pin on the map.

What it adds beyond the portal
  • Slope as a grade and a direction, so drainage and fill can be judged
  • The neighbouring heights north, south, east and west
  • The airport height cap at the same point, read in the same run
What it costs
Free every run

Run it as often as you need. Nothing is deducted.

How to read the result

Elevation in metres above sea level, slope in degrees and percent with a band (flat, gentle, moderate, steep), and the compass direction the ground falls towards. Below about five metres near the coast, run the zones mini for the flood layer.

Where the data comes from

The Copernicus 90 m digital elevation model for height, a 30 m grid for slope and aspect, and the airport zoning limits for the height cap.

Questions people ask

Short answers, no jargon.

How accurate is the height?

It is a 90 m terrain model, so treat the figure as the height of the ground around the plot, not a surveyed spot level.

What does aspect mean?

The compass direction the ground falls towards. A plot that falls north east drains that way.

Is this free?

Yes, both the terrain read and the airport height check are free.

Still unsure? Ask LandLens One, it can reason about this parcel with you.
