FAQ
What do I need to provide to get started?
Please provide your raw data (CSV, Excel with coordinates, Shapefile, KML, or scanned map/image) along with a brief description of your project goals and preferred map styling or dimensions.
Can you work with historical or scanned paper maps?
Yes! I specialize in georeferencing and digitizing historical maps, master plans, and scanned aerial photos, accurately aligning them to modern GIS coordinate systems.
Which software do you deliver the project files in?
All standard project files are built in QGIS (.qgz), ensuring open-source compatibility and easy sharing. I can also export universally compatible spatial data formats (Shapefile, GeoJSON, GeoPackage).
