I will build an interactive web map or gis dashboard from your data


About this gig
Give your data a map people can actually use: click, zoom, filter and share with a link. No ArcGIS Online subscription needed, and it runs in any browser, including phones.
Recent work (see the gig gallery): a satellite burn-severity map with a before/after swipe and 27,000 buildings; a tourism and terrain map of Montenegro; and a PostGIS pipeline that joins 221,000 Florida parcels to FEMA flood zones and rebuilds its web map automatically every week.
Good for:
- Project sites and study-area maps for consultants
- Property, parcel and land portfolios
- Nonprofit impact maps and research results
- Dashboards that update themselves when your data changes
- Embedding in WordPress, Squarespace or your own site
You get: a web map (HTML/JS) you own outright, free hosting on GitHub Pages or files for your own site, and instructions for updating the data.
About me: environmental scientist at an engineering firm who builds maps in Python, Leaflet, PostGIS and QGIS. Message me with your data and I'll suggest the right package.

FAQ
Do I need to pay for hosting?
No. I can host it free on GitHub Pages, or hand you the files to put on your own website.
Can the map update itself when my data changes?
Yes. In the Premium package I can set up a scheduled pipeline that pulls fresh data, checks it and rebuilds the map automatically.
Can you put the map on my WordPress or Squarespace site?
Yes. I'll give you an embed code that works on WordPress, Squarespace, Wix or any site that accepts HTML.
