You can set the breaks of geom_contour_filled to start at your 75th centile, and make the NA value of scale_fill_manual transparent. You also need to draw in the default contour lines:

Faster methods to create geodataframe from a Dask or Pandas dataframe

Asked 2022-Mar-31 at 20:54

Problem

I'm trying to clip a very large block model (5.8gb CSV file) containing centroid x, y, and z coordinates with an elevation raster. I'm trying to obtain only the blocks lying just above the raster layer.

I usually do this in ArcGIS by clipping my block model points to the outline of my raster and then extracting the raster values to the block model points. For large datasets this takes an ungodly amount of time (yes, that's a technical term) in ArcGIS.

How I want to solve it

I want to speed this up by importing the CSV to Python. Using Dask, this is quick and easy:

How can I perform neighborhood analysis in terra or raster and keep the same NA cells of the input?

Asked 2022-Mar-23 at 13:12

I want to perform a neighborhood analysis in R to smooth the layer I have but keeping all the NAs of the input raster intact.

However, when I do, for instance, the following, the calculation "propagates" over the NA values - what it is an undesiderable behavior, in my case.

Aligning Natural Earth Geojson and Raster to render in D3

Asked 2022-Mar-20 at 08:06

I am trying to render the world map with elevation data using D3.

For this I use Natural Earth 50m land geojson : https://github.com/martynafford/natural-earth-geojson/tree/master/50m/physical

And Natural Earth elevation raster data : https://www.naturalearthdata.com/downloads/50m-raster-data/50m-shaded-relief/

I am using this tutorial : https://datawanderings.com/2020/08/08/raster-backgrounds/

So I first found the bounds of the geojson :

...

ANSWER

Answered 2022-Mar-20 at 08:06

A Mercator is usually clipped at roughly 85 degrees North/South (~85.05113 N/S) - as further than this you get a map that is taller than it is wide, and one that gets much much taller for every extra degree north/south included in the extent..

D3 clips features using this limit:

The spherical Mercator projection. Defines a default projection.clipExtent such that the world is projected to a square, clipped to approximately ±85° latitude.

The northern bounds are fine, but the southern bounds of the geojson is -89.998926 degrees which you use to cut the image. But as D3 clips the geojson, your stretching the image by a different amount as compared with the geojson, hence the issue you see.

The solution should be to clip the image to a bounds that is representative of the limits of what D3 will render for a Mercator (85.05113 degrees south) not the limits of the data itself.

I haven't looked up how faithfully gdal implements EPSG:3395 as the definition provides for a projected bounds of 80 degrees south and 84 degrees north - though looking at the image, this doesn't appear to be an issue.

You can also use the cleaner fitSize methods for D3 projections (d3v4+):
