I will create custom interactive maps and heatmaps


About this gig
Turn your location data into a clear, professional, and interactive map.
I create custom maps and heatmaps from CSV, Excel, GeoJSON, latitude/longitude coordinates, postal codes, or other structured location data.
Your map can include:
Clickable markers with popups and tooltips
Marker clustering for large datasets
Heatmaps to show density or activity
Choropleth maps by area or region
Custom colors, icons, legends, and layers
Basic data cleaning and preparation
A standalone HTML file that opens in any modern browser
You will receive:
A tested interactive map
Clean source files
Sample output
Clear usage instructions
Revisions based on your selected package
Please contact me before ordering and send a sample of your data, the number of locations, and an example of the result you want.
Important: Geocoding large lists of incomplete addresses, live GPS tracking, website development, database connections, API costs, server deployment, and advanced GIS analysis are not included unless agreed through a custom offer.

FAQ
What data do you need from me?
Please send a representative sample of your CSV, Excel, or GeoJSON file. Ideally, the data should contain latitude and longitude coordinates, location names, and any information you want displayed in markers or popups.
Do you support GeoJSON files?
Yes. I can use GeoJSON data to display points, lines, boundaries, regions, choropleth maps, and interactive layers. Please send a sample before ordering so I can confirm the scope.
Can you update the map later if my data changes?
Yes. Small corrections within the original requirements are covered by the included revisions. A new dataset, additional locations, or new map features after delivery may require a new order or custom offer.
What if my data is not in CSV or Excel?
I can also review GeoJSON, JSON, coordinates, postal codes, and other structured formats. Please send a sample first, as data conversion or extensive cleaning may require an additional charge.
Should I contact you before placing an order?
Yes. Please send a data sample, the approximate number of locations, the map type you need, and an example of your expected result. I will confirm the correct package and delivery time.
What types of maps can you create?
I can create interactive marker maps, marker cluster maps, heatmaps, choropleth maps, and maps with multiple layers, custom popups, tooltips, legends, colors, and icons.
How will the map be delivered?
The map is normally delivered as a standalone HTML file that opens in a modern web browser. Depending on the project, I can also provide the processed data, Python source files, and clear usage instructions.
Can you create a map if I only have addresses or postal codes?
Possibly. Addresses and postal codes may need geocoding before they can be mapped. Please send a sample first because incomplete data, large lists, or paid API requirements may need a custom offer.
Does this Gig include website embedding or live data?
No. Website development, web embedding, live database connections, real-time GPS tracking, server deployment, and external API costs are not included in the listed packages unless agreed separately.
