This data is amassed in four different areas/themes: Hydrography, Transportation, Culture, and Land Cover.
When we source data in-house, the data would be procured as a vector (points, lines, and polygons). “Both raster and vector data are important for our day to day tasks here at East View Geospatial. Digital elevation models are a good example of continuous raster data.” Continuous rasters represent values that are above/below sea level.Where one value might represent land cover, another may represent a river. Discrete rasters are easy to distinguish as the data is organized into themes.However, raster data can be organized into two separate categories, discrete data & continuous data. Primarily you will see raster data used in digital aerial photographs, satellite imagery, or even digital pictures.
Raster data is made of pixels that are compiled into rows and columns.
