![]() ![]() In this paper, we saved the image data and building vector data of Guilin University of Technology to Oracle database. This article proposes a method to interpret vector data and raster data. And there is still not a proper way to solve the problem. Liu, X.Įven though geomatique is so developed nowadays, the integration of spatial data in vector and raster formats is still a very tricky problem in geographic information system environment. It is meant for a general idea only.Vector and Raster Data Storage Based on Morton Code The research data is generally dynamic in nature. DISCLAIMER - The information provided above is a one-time study done by the author. ECWP (Enhanced Compression Wavelet Protocol): ECWP is a streaming protocol developed by ERDAS for efficiently accessing and visualizing large raster datasets over networks. SID (LizardTech MrSID Image File): SID is a raster format used for storing compressed images, commonly used for aerial and satellite imagery.Ģ0. TIFF (Tagged Image File Format): TIFF is a flexible format widely used for raster data storage, supporting multiple compression methods, colorspaces, and bit depths.ġ9. ![]() SDTS (Spatial Data Transfer Standard): SDTS is a format designed for transferring spatial data between different GIS systems, including raster datasets.ġ8. ![]() MrSID (Multiresolution Seamless Image Database): MrSID is a compressed image format known for its high compression ratios and rapid visualization capabilities, commonly used for aerial and satellite imagery.ġ7. IMG (ERDAS IMAGINE): IMG is a raster format associated with ERDAS IMAGINE software, used for storing satellite imagery and associated metadata.ġ6. DTED (Digital Terrain Elevation Data): DTED is a format for storing digital elevation models (DEMs) derived from elevation data, often used for terrain analysis and visualization.ġ5. ENVI (ENVI Image File): ENVI is a format commonly used in remote sensing applications for storing multi-band imagery along with metadata and calibration information.ġ4. Department of Defense for geospatial and imagery data, including raster data.ġ3. NITF (National Imagery Transmission Format): NITF is a format used by the U.S. BMP (Bitmap): BMP is a common uncompressed raster format that stores pixel data in a straightforward manner, suitable for simple imagery and graphics.ġ2. 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. The Open Geospatial Consortium (OGC) is an international organization that sets standards for geospatial data and technologies. ![]()
