GIS Projection Audit Tool

Overview

The GIS Projection Audit Tool is an ArcPy-based utility that scans GIS datasets within a folder, reports coordinate system information, identifies projection inconsistencies, and optionally reprojects datasets to a user-specified WKID.

The tool is designed to support GIS QA/QC workflows by helping users quickly inventory spatial references and standardize datasets before analysis.

Features

• Scans datasets within a folder
• Reports projection name and WKID
• Reports dataset type
• Detects undefined projections
• Identifies multiple projections within a project
• Reprojects datasets to a common WKID
• Creates reprojected copies without modifying source data
• Generates console-based projection and reprojection reports

Requirements

• ArcGIS Pro
• ArcPy

Usage

1. Update the input_folder variable to point to the folder containing GIS datasets.
2. Run the script.
3. Review the projection report.
4. When prompted, choose whether to reproject datasets.
5. Enter the target WKID if reprojection is requested.
6. Review the reprojection report.

Example Workflow

1. Scan datasets
2. Identify projection inconsistencies
3. Select a target WKID
4. Reproject datasets
5. Review results

Future Changes

• Add aditional QA/QC functionality: inspect topography, data, etc
