GIS Skill — Integration Reference

Cross-application geospatial skill covering supported CRS, data formats, and application integration steps for the digitalmodel.gis module (WRK-020).

1. Supported Coordinate Reference Systems

Auto-detect UTM zone from longitude:

from digitalmodel.gis.core.crs import get_utm_epsg
epsg = get_utm_epsg(longitude=-1.5, latitude=57.0)  # returns "EPSG:32630"

2. Supported Data Formats

3. Application Integration

3.1 QGIS

Generate a ready-to-open .qgs project file from a WellLayer:

from digitalmodel.gis.integrations.qgis_export import QGISExporter
from digitalmodel.gis.layers.well_layer import WellLayer

layer = WellLayer.from_csv("wells.csv", lat_col="lat", lon_col="lon")
exporter = QGISExporter(layer)
exporter.generate_project("wells.qgs")          # open in QGIS 3.x
exporter.generate_well_qml("wells_style.qml")  # well marker style

Load a GeoTIFF bathymetry layer inside QGIS Processing Python console:

iface.addRasterLayer("/path/to/bathymetry.tif", "Bathymetry")

3.2 Blender — Well Markers

Generate a Blender Python script that positions well cylinders in 3D:

from digitalmodel.gis.integrations.blender_export import BlenderExporter
from digitalmodel.gis.layers.well_layer import WellLayer

layer = WellLayer.from_csv("wells.csv", lat_col="lat", lon_col="lon")
exporter = BlenderExporter(layer)
exporter.write_well_script("add_wells.py")
# In Blender: Text editor > Open add_wells.py > Run Script

3.3 Blender — Terrain / Bathymetry Mesh

Convert a GeoTIFF to an OBJ mesh that Blender can import directly:

python scripts/gis/geotiff-to-blender.py bathymetry.tif --output terrain.obj
# Optional: subsample to reduce vertex count
python scripts/gis/geotiff-to-blender.py bathymetry.tif --output terrain.obj --subsample 4

In Blender: File > Import > Wavefront (.obj) — select terrain.obj.

Scale defaults: 1 m = 0.001 Blender units (km scale). Override with --scale-xy and --scale-z.

3.4 QGIS — Import Terrain as CSV Point Cloud

python scripts/gis/geotiff-to-blender.py bathymetry.tif --output points.csv
# QGIS: Layer > Add Layer > Add Delimited Text Layer > select points.csv
# Set X=x, Y=y, Z=z, CRS = source CRS of the GeoTIFF

3.5 worldenergydata.gis Module

# Access BSEE well locations with CRS support
from worldenergydata.bsee import load_wells
wells_df = load_wells()  # lat/lon columns in WGS84
