FAQ Frequently Asked Questions

What types of geographic data can I visualize?
The visualizer supports points (markers), lines (paths/routes), polygons (areas/boundaries), and multi-geometry features from GeoJSON files. This covers most common geographic data types including GPS tracks, boundaries, and location datasets.
Can I customize how my data appears on the map?
Yes, most visualizers allow customization of colors, symbols, line styles, fill patterns, and popup content. You can often style features based on their properties for data-driven visualization and better information presentation.
What's the maximum file size I can upload?
File size limits vary by tool but typically range from 10-50MB for client-side processing. Very large files may cause browser performance issues. Consider simplifying complex geometries or splitting large datasets into smaller files.
Can I edit the GeoJSON data within the visualizer?
Many tools offer basic editing capabilities like moving points, adjusting boundaries, or modifying properties. However, for complex editing, dedicated GIS software is usually more appropriate than web-based visualizers.
Is my GeoJSON data stored or shared?
Most client-side visualizers process your data locally in the browser without uploading to servers. Your geographic data remains private unless you explicitly choose to share or export it through the tool's features.
