Raster GIS divides study area into a regular grid of cells Each cell contains one value Either integer or floating point . 5/34 Raster \ Vector Comparison

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

The PDF Map is used for setting the output spatial reference of the TIFF, if the Write GeoTIFF Tags setting is enabled. The PDF Map is also used to define the extent of the output TIFF, if the Clip Output to Map option is enabled.

ArcGIS is a set of tools that Raster Model • Divides the entire study area into a regular grid of cells in specific sequence – The conventional sequence is row by row from the top left corner – Each cell contains a single value – Is space-filling since every location in the study area corresponds to a cell in the raster – One set of cells and associated values is a layer A single band raster holds one value per cell. color temperature elevation Even if it’s displayed in colors other than gray! light intensity A raster image with scaled values between 0 and 256 is sometimes called “grayscale.” Raster Data in ArcGIS 9.0 – Geodatabase: • Raster column • Rasters as attributes of feature classes • Personal geodatabase raster data storage – ArcSDE: • Raster Dataset pyramid update enhancement • Improved loading speeds – ArcGIS: • Enhanced Raster Catalog functionality • Enhanced Rendering of Raster Catalogs Academia.edu is a platform for academics to share research papers.

performing analysis in raster GIS were de˙ned by Dana Tomlin with his map algebra. During the sixties, the ˙eld of GIS starts developing itself from those seminal works. GIS is not anymore an experimental tool, and it starts to become and important part of the cartographic world. From this moment, GIS evolves through several di˛er-

OVERVIEW This chapter reviews the main methods of GIS data capture and transfer and introduces key practical management issues. It distinguishes between primary (direct measurement) and secondary (derivation from other sources) data capture for both raster and vector data types.

PDF, the Portable Document Format, is a popular graphics file format that supports vector and raster graphics in a single compact file. A single PDF file can contain multiple pages, and the format has the ability to preserve layers and graphic feature attributes and map georeference information.

ENVI puede usarse para llevar a cabo numerosas técnicas de Elección de criterios. El método se desarrolla bajo el modelo de datos espaciales raster.

Introduction to GIS 2 Introduction Definition of GIS Like the field of geography, the term Geographic Information System (GIS) is hard to define. It represents the integration of many subject areas. Accordingly there us no absolutely agreed upon definition of a GIS (deMers, 1997).
