About The PEIT Map Creator

Interactive environmental mapping — no ArcGIS Pro license required

What is the PEIT Map Creator?

The PEIT Map Creator (Permitting and Environmental Information Tool) generates interactive web maps showing environmental features that intersect with your project area. It queries 130+ federal and state environmental databases hosted on ArcGIS FeatureServers and produces a self-contained HTML map along with PDF and Excel reports.

The tool replicates the functionality of NTIA's APPEIT without requiring an ArcGIS Pro license, making environmental permitting research accessible to anyone with a web browser.

How It Works

Step 1: Upload Your File

Drag and drop a geospatial file (GeoJSON, Shapefile, KML/KMZ, GeoPackage, or FileGDB) onto the upload area.

Step 2: Draw Your Own Geometry

No file? Draw polygons, lines, or points directly on an interactive map using the built-in drawing tools.

Step 3: Configure and Process

Set your project name, buffer distance, and clip radius, then hit Run to start querying 130+ environmental layers.

Step 4: Results Ready

When processing completes, view your live map, download a ZIP package, or grab the PDF and Excel reports directly.

Step 5: Explore Your Map

Step 6: Navigate and Analyze

Toggle layers, search by name, measure distances, download individual layers in multiple formats, and right-click to copy coordinates.
