GISGP GIS Tools vs Gis MCP

read_file_gpd

Reads a geospatial file and returns stats and a data preview.

append_gpd

Reads two shapefiles directly, concatenates them vertically.

merge_gpd

Merges two shapefiles based on common attribute columns, This function performs a database-style join, not a spatial join. Args: left_shapefile_path: Path to the left shapefile. The geometry from this file is preserved. right_shapefile_path: Path to the right shapefile to merge. output_path: Path to save the merged output shapefile. how: Type of merge. One of 'left', 'right', 'outer', 'inner'. Defaults to 'inner'. on: Column name to join on. Must be found in both shapefiles. left_on: Column name to join on in the left shapefile. right_on: Column name to join on in the right shapefile. suffixes: Suffix to apply to overlapping column names.

overlay_gpd

Overlay two GeoDataFrames using geopandas.overlay. Args: gdf1_path: Path to the first geospatial file. gdf2_path: Path to the second geospatial file. how: Overlay method ('intersection', 'union', 'identity', 'symmetric_difference', 'difference'). output_path: Optional path to save the result. Returns: Dictionary with status, message, and output info.

dissolve_gpd

Dissolve geometries by attribute using geopandas.dissolve. Args: gdf_path: Path to the geospatial file. by: Column to dissolve by (optional). output_path: Optional path to save the result. Returns: Dictionary with status, message, and output info.

explode_gpd

Split multi-part geometries into single parts using geopandas.explode. Args: gdf_path: Path to the geospatial file. output_path: Optional path to save the result. Returns: Dictionary with status, message, and output info.

clip_vector

Clip vector geometries using geopandas.clip. Args: gdf_path: Path to the input geospatial file. clip_path: Path to the clipping geometry file. output_path: Optional path to save the result. Returns: Dictionary with status, message, and output info.

sjoin_gpd

Spatial join between two GeoDataFrames using geopandas.sjoin. Args: left_path: Path to the left geospatial file. right_path: Path to the right geospatial file. how: Type of join ('left', 'right', 'inner'). predicate: Spatial predicate ('intersects', 'within', 'contains', etc.). output_path: Optional path to save the result. Returns: Dictionary with status, message, and output info.

sjoin_nearest_gpd

Nearest neighbor spatial join using geopandas.sjoin_nearest. Args: left_path: Path to the left geospatial file. right_path: Path to the right geospatial file. how: Type of join ('left', 'right'). max_distance: Optional maximum search distance. output_path: Optional path to save the result. Returns: Dictionary with status, message, and output info.

point_in_polygon

Check if points are inside polygons using spatial join (predicate='within'). Args: points_path: Path to the point geospatial file. polygons_path: Path to the polygon geospatial file. output_path: Optional path to save the result. Returns: Dictionary with status, message, and output info.

write_file_gpd

Export a GeoDataFrame to a file (Shapefile, GeoJSON, GPKG, etc.). Args: gdf_path: Path to the input geospatial file. output_path: Path to save the exported file. driver: Optional OGR driver name (e.g., 'ESRI Shapefile', 'GeoJSON', 'GPKG'). Returns: Dictionary with status and message.

buffer

Create a buffer around a geometry.
