Understanding Merge Multiple GIS Files
Files, layers and supporting parts
Merge multiple GeoJSON, KML, GPX, or zipped Shapefile layers into one FeatureCollection with source-layer metadata.
Merge Multiple GIS Files handles the relationship between a GIS dataset and its file container. Some formats use one file while others rely on sidecar files, internal layer names or a specific archive structure.
How to verify the package
Drop multiple files together, or paste two GeoJSON inputs. Mixed geometry types are supported; source CRS values must already match.
Open the Merge Multiple GIS Files result in an independent viewer and confirm every expected layer, geometry type and attribute is present. A valid archive can still be incomplete when a required component was omitted.
