![]() ![]() PNG (Portable Network Graphics): PNG is a widely used lossless image compression format that supports transparency and is often used for storing raster graphics, including maps and icons.ġ1. BSQ (Band Sequential): BSQ is a format where multiple bands of a raster dataset are stored sequentially, making it suitable for efficient data access in certain applications.ġ0. BIP (Band Interleaved by Pixel): BIP is a format where multiple bands of a raster dataset are interleaved pixel by pixel, making it easy to access and process multi-band imagery.ĩ. BIL (Band Interleaved by Line): BIL is a simple format for storing raster data, where each band is stored as a separate file, and the pixels are arranged in a sequential line order.Ĩ. HDF (Hierarchical Data Format): HDF is a format for storing large and complex datasets, often used for remote sensing and scientific data, including raster imagery.ħ. GML allows for the representation of both vector and raster data, making it suitable for interoperability between different GIS platforms.Ħ. GML (Geography Markup Language): Although GML is primarily an XML-based format for encoding geographic data, it can be used to store raster data as well. ![]() It supports georeferencing and can store both imagery and geospatial metadata.ĥ. JPEG2000 (JP2): JPEG2000 is an image compression standard that provides efficient and lossless or lossy compression for raster data. ECW files are commonly used for aerial and satellite imagery.Ĥ. It uses a wavelet compression technique to achieve high compression ratios while maintaining good image quality. ECW (Enhanced Compressed Wavelet): ECW is a proprietary raster format developed by ERDAS. It supports multidimensional arrays, making it suitable for storing raster datasets with multiple variables or dimensions, such as time slices or different bands of a satellite image.ģ. NetCDF (Network Common Data Form): NetCDF is a self-describing, machine-independent data format widely used for storing scientific and environmental data. It can store various types of geospatial information, including coordinate reference system (CRS) information, image georeferencing, and attribute data.Ģ. GeoTIFF (Georeferenced Tagged Image File Format): GeoTIFF is a common and widely supported raster format that allows for the embedding of geospatial metadata within the TIFF file structure. Some of the raster file formats compliant with OGC standards are:ġ. Interpolation tools: Kriging, IDW, Splines, etc.The Open Geospatial Consortium (OGC) is an international organization that sets standards for geospatial data and technologies.The following are examples of tools in ArcMap will convert rasters to vectors or vectors to rasters: Expected types of analysis: some tools only work with raster or vector data.Available storage: some rasters are really large.Other factors that can influence your decision include: ![]()
