A raster grid format is a data model for satellite data and otherremote sensingdata. For raster positions, it’s simple to understand cell size. Map algebrawith raster data is usually quick and easy to perform. Overall, quantitative analysis is intuitive with discrete or continuous rasters. Wha...
Vector Data and Raster Data in GISAli Jaafar
BMP (.bmp): A basic and uncompressed raster format that retains high image quality but leads to large file sizes. Common in early Microsoft Windows applications. RAW (.raw): A format that contains unprocessed image data from a camera sensor. Typically used in professional photography for maximum...
Raster vs Vector Maps: What's the Difference? Take a look at the key differences of raster vs vector data for geospatial data visualization. Advantages and disadvantages of each, and which are the best. Read more Report Modernizing the Geospatial Analysis Stack ...
Free vector and raster map data at 1:10m, 1:50m, and 1:110m scales Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110 million scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, ...
The vector model uses points and line segments to identify locations on the earth while the raster model uses a series of cells to represent locations on the earth. The figure represents vector (left) versus raster (right) data. One of the most common types of raster data is land cover ...
Map tilesare small, square graphical chunks of geographic data, typically rendered as images (raster tiles) or vector-based graphics (vector tiles). These tiles are arranged in a grid and served at multiple zoom levels to compose an entire map view. ...

There are also open source engines like Mapnik that can do the same out of any geospatial data. That engine in combination with TileCache software can produce raster map tiles out of any data, but there is one big problem: rendering in realtime. Creating raster imagery can be CPU and ...
GIS矢量栅格一体化无缝连接比例尺匹配Integrating Raster with Vector technology is one of the directions in recent GIS development. On the basis of practice, this paper introduces a GIS system which integrates Raster with Vector . It's design,data management,data matching and integrated analises are ...
