raster data

Raster and vector are two major types of data format in GIS and converting raster data into vector one is of great importance for GIS.

GDAL also enables programmers to project raster data onto worldwide geographical coordinates, known as georeferenced coordinates.

However, storage might not be quite as important for raster data, whose spatial component likely contains fairly simple numerical data.

Image classification is an important approach for transforming raster data to vector data.

The data model of urban geo-environmental vector data and raster data synthesis management is developed.

Geophysical and geochemical data will be transferred to images by raster data formed by interpolations .

Applications store GIS data using two distinct data structures: raster data and vector data.

Raster data is non-geometric data defined by a grid of values covering a spatial area.

As raster data is very conducive to space analysis of overlay analysis, which usually takes vector data will be converted into raster data.

In the raster data model, the map's accuracy also depends on the map's scale.

Based on ORDBMS, a spatial-temporal data modeling method is presented, which can integrate both vector and raster data.

See the link to the GDAL raster format information page in Resources for more information on other raster data formats.

The library gives programmers a common data model covering all raster data formats and -- through OGR -- vector data formats.
