Access is granted by invitation. Use the form below to apply.

What It Does

Everything in one platform

From custom data fields to embeddable widgets, County Maps Pro gives your team a complete toolkit for geographic data. No GIS software required.

All 3,143 US Counties

Complete coverage of every US county with accurate SVG boundaries, FIPS codes, and state groupings. Ready to use the moment your account is set up.

Custom Data Fields

Attach any data to any county: text, numbers, links, images, tags, and color swatches. Design the fields, import your data, and the map reflects it instantly.

Map Points & Markers

Drop interactive points anywhere on the map with custom labels, icons, and popup details. Great for office locations, event sites, field assets, and more.

Rich Popup Cards

Clicking a county reveals a floating card displaying all your custom fields (images, links, tags, paragraphs) styled to match your own color palette.

One-Line Embed

Add a live, interactive map to any page with just a script tag and a single div. No iframes, no framework dependency. It works on any website or CMS.

Built for Security

Includes full user authentication, CSRF protection, role-based access control, and rate-limited login with automatic lockout. Security is built in from the ground up.

CSV & JSON Import / Export

Bulk-load county data from a spreadsheet in seconds, export maps for backup or migration, and duplicate any map with a single click.

Team & User Management

Invite teammates as editors or admins. The superadmin controls roles, sees a full audit log of every action, and can manage all maps across all users.

Public Map Sharing

Publish any map as a public URL so anyone can explore it without logging in. Perfect for reports, public dashboards, or informational websites.

Under the Hood

Built for real data workflows

County Maps Pro is designed around how data teams actually work, not just how maps look.

Data Fields

Every field type your data needs

Build the exact schema your dataset requires. Each map can have a completely different set of fields. There is no global template to fight with.

  • Text & long-form paragraph
  • Number, currency, percentage
  • URL links (open in new tab)
  • Image (displayed in popup header)
  • Tag lists (comma-separated, shown as pills)
  • Color swatch (visual indicator per county)
  • Custom label & inline / stacked layout per field

Popup Display Modes

Flexible popup layouts per map

Choose how the county popup card behaves to match the density of your data and the needs of your audience.

  • Scroll mode: all fields in one scrollable card
  • Paginated mode: fields split across pages with prev/next
  • Tabbed mode: fields organized into labeled tabs
  • Optional image header or slim color header
  • Floating card that positions itself to stay on screen

Security & Access Control

Enterprise-grade security baked in

County Maps Pro was designed with security as a first-class concern from day one, not bolted on later.

  • CSRF token protection on all state-changing endpoints
  • Rate-limited login with 15-minute lockout after 5 failures
  • Role-based access: user, admin, superadmin
  • Per-map member access lists
  • Password reset via secure emailed token
  • Rotatable app secret key
  • Full audit log of all admin actions

Admin Dashboard

A complete management interface

Everything is managed through a polished, single-page admin panel. No command line, no config file edits once you are up and running.

  • Dashboard with map count & quick links
  • Map list, create, edit, duplicate, delete
  • County data editor (click any county to edit its fields)
  • Map point manager (add, edit, delete markers)
  • User management panel (admin only)
  • Global settings (app name, registration toggle)
  • Full audit log view (admin only)

Embed API

Drop your map into any website

The embed script is a self-contained JavaScript file. Load it once per page, then place as many map containers as you need, each with its own API key.

your-page.html
<!-- 1. Load the script (once per page) --> <script src="https://app.countymaps.us/embed/cmap.js" ></script> <!-- 2. Place the map container --> <div class="cmap-embed" data-api-key="your_api_key_here" data-height="520" ></div>

Unique API Key Per Map

Each map gets its own 32-character API key generated on creation. You control which maps are public and which stay private.

Fully Responsive

Maps fill their container width automatically. Set a fixed height in pixels or let it adapt. Looks great on any screen size.

CSS Custom Property Theming

Override every color (county fill, hover, active, popup background, header gradient) using CSS variables on the host page.

Multiple Maps Per Page

Load the script once and place as many cmap-embed divs as you need, each with a different API key and configuration.

D3 + TopoJSON Powered

Crisp SVG rendering at any size, backed by D3.js v7 and TopoJSON loaded with SRI integrity verification. Fast and tamper-proof.

Who It's For
