I have shape files with polygon/geometry info. I am exporting the file after Sedona integration with Kepler. I o/p file is in .html. I want to reduce the file size. Pls suggest in case any option is available.
Hi @NT911, When dealing with shape files and trying to reduce the file size, there are a few strategies you can consider:
Simplify Geometries:
One effective method is to simplify the geometries in your shape file. This involves reducing the number of vertices while maintaining the overall shape. Tools like Mapshaper or QGIS can help you achieve this.
By simplifying the geometries, you can significantly reduce the file size without compromising too much on accuracy.
Remove Unnecessary Attributes:
Shape files often come with attribute data associated with each geometry. If some of these attributes are not essential for your use case, consider removing them.
By eliminating unnecessary attributes, you can reduce the overall size of the file.
Compression:
Since your output file is in HTML format, you can explore using compression techniques. For example:
Gzip: Compress the HTML file using Gzip, which is widely supported by web servers and browsers.
Minify: Minify the HTML content by removing unnecessary whitespace, comments, and redundant code.
Image Compression: If your HTML file includes images (such as map tiles), ensure they are properly compressed.
GeoParquet:
While not directly related to HTML files, consider using GeoParquet for efficient storage and querying of spatial data. GeoParquet is a columnar storage format optimized for geospatial data.
If you’re using KeplerGl for visualization, explore its configuration options. KeplerGl allows you to customize the map display, layers, and other settings.
By adjusting the configurations, you might be able to optimize the output for your specific use case.
