Raster Data

GIS Server allows you to add and display raster data on your maps.

Supported Raster Formats

The system allows you to add and display raster data in the following formats:

Primary Formats

• GeoTIFF (.tif, .tiff) - Industry standard for georeferenced imagery
• PNG (.png) - Lossless compression for detailed imagery
• JPEG (.jpg, .jpeg) - Compressed imagery for web applications
• BMP (.bmp) - Uncompressed bitmap imagery

Tile Generation and Optimization

The tile generation system provides efficient methods for serving raster data over the web with optimized performance and scalability.

Tile System

• Multi-resolution Tiling: Generate tiles at multiple zoom levels
• Pyramid Structure: Efficient hierarchical tile organization
• Caching Strategy: Intelligent caching for improved performance
• Compression: Optimize tile size and transfer speed
• Format Options: PNG, JPEG, and WebP tile formats

Performance Optimization

• Progressive Loading: Load tiles based on current view
• Background Processing: Non-blocking tile generation
• Parallel Processing: Multi-threaded tile generation
• Memory Management: Efficient memory usage for large datasets
• Storage Optimization: Compressed storage with fast access
