Cuando la aplicación GIS abre la fotografía, utiliza la información de posición para asegurar que aparezca en el lugar correcto en el mapa. Normalmente esta información consiste de una coordenada del píxel superior izquierdo de la imagen, el tamaño de cada píxel en la dirección X, el tamaño de cada píxel en la dirección Y, y la cantidad (si hay alguno) para girar la imagen.

GIS Fundamentals Lab10: Introduction to Raster Analysis 7 Here we have only two files, so we can only enter a and b for files in any formula. If we enter c, or any higher letter, then the raster layer is not specified, and we’ll get erroneous results. Note two additional things. First, we can add several more layers, e.g., if I had
Materialet är i raster format. Materialet är producerat från ett raster material till ett GIS lager och grundar sig på den geologiska kartan, det modellerade siktdjupet av A Dicander — (GIS), based on elevation data for all water bodies in the catchment. beläget ovanför marknivån, så som sjöar och vattendrag, skapa ett raster som är beklätt.

Raster to types of analyses that can be performed on raster data vs. vector data vary significantly due to differences in structure. If you are creating a raster of treatment units, you would likely want the Value field to be the unit ID number.
