sample Module¶
-
drapery.ops.sample.drape(raster, feature)¶ Convert a 2D feature to a 3D feature by sampling a raster
Parameters: - raster (rasterio) – raster to provide the z coordinate
- feature (dict) – fiona feature record to convert
Returns: shapely Point or LineString of xyz coordinate triples
Return type: result (Point or Linestring)
-
drapery.ops.sample.sample(raster, coords)¶ Sample a raster at given coordinates
Given a list of coordinates, return a list of x,y,z triples with z coordinates sampled from an input raster
Parameters: - raster (rasterio) – raster dataset to sample
- coords – array of tuples containing coordinate pairs (x,y) or triples (x,y,z)
Returns: array of tuples containing coordinate triples (x,y,z)
Return type: result
