FAQ
What information do you need from me to get started ?
You’ll need to provide your geospatial data (or data sources), project objectives, target users, preferred mapping platform (if any), and hosting details. Without clear data and use cases, timelines and accuracy will suffer.
Can you work with my Existing GIS Data and Systems ?
Yes. I work with most GIS formats and platforms (Shapefiles, GeoJSON, raster data, PostGIS, ESRI, GeoServer, APIs). If your data is messy or inconsistent, cleanup and optimization may be required and will be scoped separately.
Do you deliver only Maps or full geospatial application ?
Both. I build simple interactive maps as well as full-scale geospatial web applications with backend services, databases, user roles, and analytics—depending on your requirements and budget.
How do you handle performance for large datasets or high traffic ?
Large datasets are handled using spatial indexing, tiling, clustering, caching, and optimized databases (PostGIS, GeoServer, MapServer). Performance planning is done upfront to avoid scaling issues later.
Do you Deliver post-delivery support and maintenance ?
Yes, but it’s not assumed. Ongoing support, updates, server maintenance, or data refreshes are offered under a separate agreement after project delivery
