Rasters can affect other layers during export in the following ways: Raster layers, such as orthophotos, consolidate all layers below them into a single Image layer. Place raster layers lower in the ArcMap table of contents to avoid this problem. This new text is written for the second GIS course taken by Geography majors. The primary focus of GIS Modeling in Raster is on the process of cartographic modeling and GIS modeling.

Raster Analysis Moving windows and kernals can be used with a mean kernal to reduce the difference between a cell and surrounding cells. (done by average across a group of cells) Raster data may also contain “noise”; values that are large or small relative to their spatial context.

Because having images containing multiple bands of light is so useful in GIS, raster data are often provided as multi-band images. Each band in the image is like a separate layer. The GIS will combine three of the bands and show them as red, green and blue so that the human eye can see them. GIS Raster- och vektoranalys Kursens huvudsakliga innehåll Den studerande ska få kunskap och färdigheter i att hantera metoder för datainsamling, integrering och konvertering av raster- och vektordata.
