Create buffers, calculate area and length, generate centroids, and compare polygon layers with the new local spatial analysis tools in GeoDataViewer Studio.
GeoDataViewer Studio now reads colors, line widths, transparency and custom icons from KML, KMZ and GeoJSON. See real screenshots and the supported properties.
Learn what a DXF file is, how DXF differs from DWG, why CRS matters in GIS, and how to open or convert CAD drawings to GeoJSON, KML, or Shapefile.
Learn what an OSM PBF file is, how it compares with OSM XML and GeoJSON, when to use regional extracts, and how to open or convert PBF data online.
Compare GIS data loading from local files to raster tiles, vector tiles, and PMTiles. Choose the right delivery pattern for browser maps and large datasets.
Learn how GeoDataViewer supports Cloud Optimized GeoTIFF (COG) and standard GeoTIFF files — drag-and-drop raster visualization in your browser.
Extract POIs from OpenStreetMap PBF or Overture Maps GeoParquet for EV charging stations, gas stations, and other places with practical GIS workflows.
Preview Shapefile, GeoJSON, KML, PMTiles, and other geospatial files inside VS Code without opening a full desktop GIS.
Compare GIS viewers from ArcGIS and QGIS to Kepler.gl and GeoDataViewer. Desktop vs browser, cost, format support, and speed.
FileGDB vs GeoPackage compared for ArcGIS and open GIS: choose FileGDB for ESRI workflows or GeoPackage for portable, multi-layer storage.
GeoJSON vs GeoPackage compared: size, portability, multi-layer support, and when to convert for web maps or GIS workflows.
GeoJSON vs Shapefile compared for GIS data exchange: choose GeoJSON for web maps and APIs or Shapefile for legacy GIS, government portals, and CRS flexibility.
GML vs GeoJSON compared for GIS: keep GML for OGC/WFS schemas or choose GeoJSON for web maps, APIs, and fast browser inspection.
GPX vs GeoJSON compared: keep GPX for GPS tracks, routes, and waypoints; choose GeoJSON for web maps, APIs, and flexible GIS properties.
Step-by-step: open a Shapefile online in your browser, upload the required sidecar files, and troubleshoot missing .dbf/.shx/.prj issues.
KML vs GeoJSON explained: compatibility, typical use cases, and the simplest way to open and convert files for modern web mapping.
MapInfo vs Shapefile compared: sidecar files, compatibility, and when to convert TAB or MIF/MID datasets into Shapefile or GeoJSON.
Shapefile vs GeoPackage compared: choose Shapefile for legacy compatibility or GeoPackage for one-file, multi-layer GIS workflows.
