Classes
- class modules.gisOperators.ConvexHullCenter
Calcualte the center of the convex hull of point samples
- Inherits from:
PipeModule
Methods:
- __init__(mname: str = 'ConvexHullCenter', auto_run: bool = True, points_table: PortTypeHint.TableData | None = None, by_xy: bool = True, x_column: str | None = None, y_column: str | None = None, longitude_column: str | None = None, latitude_column: str | None = None) None
Initialize ConvexHullCenter object.
Parameters
- points_tablePortTypeHint.TableData | None, default: None
The table contains the point samples.
- by_xybool, default: True
If True, the center will be calculated by the x and y coordinates. If False, the center will be calculated by the longitude and latitude.
- x_columnstr | None, default: None
The column name or title of the x coordinate. If None, “x_coordinate” will be used.
- y_columnstr | None, default: None
The column name or title of the y coordinate. If None, “y_coordinate” will be used.
- longitude_columnstr | None, default: None
The column name of the longitude. If None, “longitude” will be used.
- latitude_columnstr | None, default: None
The column name or title of the latitude. If None, “latitude” will be used.

- class modules.gisOperators.VrtToGeoTiff
Convert a VRT file to a GeoTIFF or PNG file with metadata.
- Inherits from:
PipeModule
Methods:
- __init__(mname: str = 'VrtToGeoTiff', auto_run: bool = True, vrt_file: str | Path | None = None, directory_path: str | Path | None = None, output_path: str | Path | None = None, colormap: str | dict | None = None, vrt_file_pattern: str | None = None, time_info_pattern: str | None = None, format: Literal[geotiff, png] = 'geotiff', compress: str = 'lzw', predictor: int = 2) None
Initialize a VrtToGeoTiff object.
Parameters
- vrt_filestr | Path | None, default: None
Path to a single VRT file. Mutually exclusive with directory_path.
- directory_pathstr | Path | None, default: None
Path to directory containing VRT files for time series processing. Mutually exclusive with vrt_file.
- output_pathstr | Path | None, default: None
Output directory for generated files. If None, creates output in same directory as input with format-specific suffix.
- colormapstr | dict | None, default: None
Colormap specification. Can be:
Plotly colorscale name: “viridis”, “plasma”, “inferno”, “magma”, “cividis”,
“turbo”, “rainbow”, “jet”, “hot”, “cool”, “RdYlBu”, “RdBu”, “Spectral”, etc.
Custom dict: {value: [r, g, b, a]} where values are 0-1 floats or 0-255 integers
Examples
- **None**: Uses default "viridis" colorscale vrt_file_pattern: str | None, default: None File pattern to match when processing directory (e.g., "*.vrt", "Depth*.vrt"). Only used when directory_path is provided. time_info_pattern: str | None, default: None Regex pattern to extract time information from filename If None, uses default patterns format: Literal["geotiff", "png"] = "geotiff", default: "geotiff" Output format: - **"geotiff"**: Generates .tif files with embedded geospatial metadata - **"png"**: Generates .png files with separate .pgw (world file), .prj (projection), and metadata.json files for GIS compatibility compress: str = "lzw", default: "lzw" Compression method for GeoTIFF. Only used when format="geotiff". Options and recommendations: - **"lzw"** (default): Lossless, good compression ratio, widely supported. Best for: Most raster data, scientific data, when file size matters. - **"deflate"**: Lossless, similar to LZW but sometimes better compression. Best for: Alternative to LZW, some software prefers deflate. - **"jpeg"**: Lossy compression, smallest files but quality loss. Best for: RGB imagery where small quality loss is acceptable.Notes
- **"none"**: No compression, largest files but fastest access. Best for: When processing speed is critical, temporary files. predictor: int = 2, default: 2 Predictor for lossless compression optimization. Only used when format="geotiff" and compress is "lzw" or "deflate". Options and recommendations: - **1** (none): No prediction, compress data as-is. Best for: Random/noisy data, already compressed data. - **2** (horizontal differencing, default): Stores differences between adjacent pixels. Best for: Most imagery, gradual spatial changes, typical raster data. Typical improvement: 20-50% better compression for spatial data. - **3** (floating point): Optimized for floating-point scientific data. Best for: Elevation models, temperature data, continuous surfaces. Typical improvement: 40-60% better compression for float32/64 data.

- class modules.gisOperators.CreatePolyLines
Create poly lines from points or bores
- Inherits from:

Initialize CreatePolyLines object.
Parameters
- boresPortTypeHint.MultiProfile1D | None, default: None
The vertical bores used when
define_poly_lines_byis"bores". define_poly_lines_by: Literal[“bores”, “points”], default: “bores” How poly lines are defined."bores": each row is a line vertex withnameandbore_number."points": each row is a line vertex withname,x_coordinate,y_coordinate, and optionallyz_coordinate. poly_lines: pd.DataFrame | list[dict[str, Any]] | None Poly line vertices, one row per point.
