Vyperdatum

Vyperdatum [definition]

Installation

Vyperdatum requires GDAL which can be installed from the conda's conda-forge channel. Below, we first create a conda environment, install GDAL and Vperdatum.

conda create -n vd python=3.11
conda activate vd
conda install -c conda-forge gdal=3.8.4
pip install vyperdatum

Usage

Vyperdatum offers a Transformer class to handle the transformation of point and raster data. The Transformer class applies transformation from crs_from to crs_to coordinate reference systems. The transformation steps can be prescribed or let the Pipeline class

from vyperdatum.transformer import Transformer
from vyperdatum.pipeline import Pipeline

crs_from = "EPSG:6346"
crs_to = "EPSG:6346+NOAA:5224"
tf = Transformer(crs_from=crs_from,
                 crs_to=crs_to,
                 steps=["EPSG:6346", "EPSG:6319", "EPSG:6318+NOAA:5224", "EPSG:6346+NOAA:5224"]
                 #  steps=Pipeline(crs_from=crs_from, crs_to=crs_to).linear_steps()
                 #  steps=Pipeline(crs_from=crs_from, crs_to=crs_to).graph_steps()                 
                 )

raster transform

tf.transform_raster(input_file=<PATH_TO_INPUT_RASTER_FILE>,
                    output_file=<PATH_TO_OUTPUT_RASTER_FILE>
                    )

point transform

# random values
x, y, z = 278881.198, 2719890.433, 0
xt, yt, zt = tf.transform_points(x, y, z, always_xy=True, allow_ballpark=False)
