I will create custom interactive maps, heatmaps and gis visualizations


About this gig
Turn your CSV, Excel, GeoJSON, or coordinate data into a polished interactive map that is easy to explore and share.
I build custom Python maps for location analysis, including:
clickable markers with popups and tooltips
marker clustering for larger datasets
heatmaps for density and activity
choropleth maps by region
custom colors, icons, legends, and layers
You will receive:
a tested standalone HTML map that opens in a modern browser
the agreed processed data files
clear usage instructions
revisions included with your selected package
Python source code is included with Premium. For Basic or Standard orders, source code is available by prior agreement or custom offer.
Minor formatting and column selection are included. Deduplication, address repair, geocoding, major restructuring, large or incomplete address lists, website embedding, live databases/GPS, paid APIs, server deployment, and advanced GIS analysis require prior agreement and may need a custom offer.
Before ordering, message me with an anonymized sample, approximate row count, preferred map type, and a reference or description of the result you want.

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.
What data cleaning is included?
Minor formatting and column selection are included. Deduplication, address repair, restructuring, geocoding, or extensive cleanup requires the Data Cleanup extra or a custom offer.
What counts as a revision?
A revision covers changes within the originally agreed scope. A new dataset, additional locations, new layers, or new functionality may require an extra 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.
When should I contact you before ordering?
Please contact me first for address-only data, incomplete location data, large datasets, multiple layers, geocoding, website embedding, live data, or server deployment. Clean coordinate or GeoJSON projects can usually use the appropriate package directly.
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.
Is Python source code included?
Python source code is included with the Premium package. For Basic or Standard orders, source code can be provided by prior agreement or through a custom offer.
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.
Should I remove sensitive information?
Yes. Please anonymize the sample and remove confidential, personal, payment, or unnecessary identifying information before sharing it.
