Frequently asked questions
Everything you need to know about building interactive maps with Mapji — map types, data, publishing, and more.
Getting started
How do I make an interactive map?
Sign up for Mapji, choose one of 9 map types, add your data by importing a GeoJSON/CSV file or connecting a Google Sheet, customize the style, and publish to your own subdomain or custom domain. No coding is required.
What is the best free map maker?
Mapji is a free, no-code interactive map maker that supports 9 map types — including heatmaps, choropleth maps, store locators, and story maps — and lets you publish to your own domain. It's free to start with no credit card required.
Do I need to know how to code to use Mapji?
No. Mapji is entirely point-and-click. You build, style, and publish maps in the browser without writing any code or installing GIS software.
How do I embed a map on my website?
Every published Mapji map can be embedded on any website with a simple iframe snippet, or you can link to it directly on your own custom domain.
Map types
What is a choropleth map?
A choropleth map shades geographic regions — countries, states, counties, or NUTS regions — by a data value, making spatial patterns in demographic, economic, or election data easy to see. In Mapji you pick a geography, join your data, and choose a color scale.
How do I make a heatmap online?
Create a Heatmap in Mapji, add your point data by uploading a file or connecting a Google Sheet, tune the radius, intensity, and color gradient, and publish. You can also weight points by a value column.
How do I build a store locator for my website?
Use Mapji's Store Locator map type. Add your locations via a Google Sheet or file upload, configure search and filter categories, then embed the locator on your website or publish it to a custom domain.
What is an isochrone map?
An isochrone map shows every location reachable within a given travel time — for example a 10-minute drive — from a starting point. It's useful for site selection, accessibility, and catchment analysis.
What is a story map?
A story map is a scroll-driven presentation that moves the map and reveals text and images as the reader scrolls through a narrative, with smooth fly-to animations between locations.
Data & sync
Can I connect a Google Sheet to my map?
Yes. For Cluster, Heatmap, Store Locator, Choropleth, and Time Slider maps you can connect a Google Sheet as a read-only, live data source. Mapji re-syncs automatically, so editing the sheet updates the map.
What data formats can I import?
You can import GeoJSON files, upload spreadsheet data, or connect a Google Sheet. Mapji auto-detects latitude and longitude columns to get you mapped quickly.
How many points can a map handle?
Mapji handles thousands of features smoothly, with a limit of 10,000 features per data source.
Publishing & domains
Can I use my own custom domain?
Yes. Publish your map to a free yourmap.mapji.com subdomain or connect your own custom domain for a fully branded experience.
Can I customize how the map looks?
Yes. Choose from built-in themes or design your own with the custom theme editor — 45+ color controls, road widths, dash patterns, label styling, and tileable fill patterns.
