Calculate Resource grid
Example of using PyWAsP to calculate a resource grid
Prepare TopographyMap
First, we need to prepare the topography map. This is done by reading the elevation and roughness maps and creating a TopographyMap object.
[1]:
import numpy as np
import windkit as wk
import pywasp as pw
bwc = wk.read_bwc(
"../../../modules/examples/tutorial_4/data/SerraSantaLuzia.omwc", crs="EPSG:4326"
)
bwc = wk.spatial.reproject(bwc, to_crs="EPSG:32629")
elev_map = wk.read_vector_map(
"../../../modules/examples/tutorial_4/data/SerraSantaLuzia.map",
map_type="elevation",
crs="EPSG:32629",
)
lc_map, lc_tbl = wk.read_vector_map(
"../../../modules/examples/tutorial_4/data/SerraSantaLuzia.map",
map_type="roughness",
crs="EPSG:32629",
)
topo_map = pw.wasp.TopographyMap(elev_map, lc_map, lc_tbl)
Define output locations
Second, we need to define the output locations. This is done by creating a dataset with the coordinates of the output locations.
Calculate resource grid
Finally, we can calculate the resource grid. This is done by calling the generalize_and_downscale function. This function takes the output locations, the boundary conditions, and the topography map as input. The output is a predicted wind climate dataset
[3]:
pwc = pw.wasp.generalize_and_downscale(output_locs, bwc, topo_map)
Plot the mean wind speed
We can plot the mean wind speed to see the result.
