GeoParquet Viewer Tool
Why analysts rely on this GeoParquet viewer
Instant columnar previews
Understand schema, geometry types, and attribute statistics immediately after loading your GeoParquet file.
Map and table side by side
Explore features on an interactive map while reading row-level metadata in a synchronized data grid.
No vendor lock-in
Work completely in the browser so sensitive location intelligence stays inside your organization.
What is GeoParquet?
GeoParquet is an extension of the Apache Parquet columnar format that standardizes how geospatial geometries and metadata are stored.
Because GeoParquet files are compact and cloud friendly, they are ideal for big spatial analytics, lakehouses, and modern data stacks.
Columnar efficiency
Parquet compresses data by column, enabling fast reads of only the fields you need.
Embedded CRS metadata
GeoParquet captures coordinate reference system details alongside geometry columns to keep projections explicit.
Interoperable geometries
It stores geometries using well-known binary (WKB) so major GIS and analytics engines can process them consistently.
How to use the GeoParquet viewer
- 1
Upload a GeoParquet file
Drag and drop a .parquet file encoded with GeoParquet metadata or select one from your device.
- 2
Inspect spatial columns
Review the geometry column, feature attributes, and CRS metadata to ensure the dataset is structured correctly.
- 3
Explore on the map
Pan, zoom, and click features to validate shapes, measure extents, and confirm values before sharing or publishing.
Get more from your GeoParquet datasets
Keep schemas descriptive
Use meaningful column names and include units so downstream analysts can interpret the data quickly.
Validate geometry integrity
Check for invalid rings, duplicated vertices, and mixed dimensionality before loading into spatial databases.
Document CRS changes
Record transformations between EPSG codes to avoid projection mistakes in downstream workflows.
GeoParquet viewer FAQs
Which files can I open?
Any Apache Parquet file that follows the GeoParquet specification, including datasets with multiple geometry columns.
Does the viewer move my data to the cloud?
No. All parsing runs locally in your browser, so confidential spatial data never leaves your computer.
How do I export results?
Once you finish reviewing, you can download the original file or copy filtered rows for use in notebooks, BI tools, or GIS apps.
