such as a name, color, pH, or cash value. Attribute data are linked with coordinate data to help define each cartographic object in the GIS. 1.10.Basic Questions 2.What is the difference between GIS and a map ? "GIS is the application that compares the tabular data and illustrates the spatial relationships. It allows for selective analysis and informed decisions. The end results of the various analyses are usually illustrated as 'maps.' GIS database that includes a soils data layer, a population data layer, an elevation data layer, and a roads data layer.

Data expands the richness of a map: giving the user a deeper, more insightful view of an area or project. As a category, GIS data is quite broad, with considerable variation in terms of: GIS data types; File formats and extensions; Data capture methods; Use cases for the data GIS data is commonly used for managing transportation issues. With the addition of environmental and topical data in a GIS platform, companies can plan for a new road or rail route. 6. Environmental Impact Analysis. Data gathered via GIS applications is vital for conserving natural resources and protecting the environment. GIS Fundamentals 2 Data Models Introduction Data in a GIS represent a simplified view of the real world.

The GIS data model specific to ESRI's ArcGIS software where all GIS data are stored in relational database management systems tables. Graphic data structure A method of storage of analog graphical data into a computer that enables the user to reconstruct a close approximation of the analog graphic through some output procedure.

overview of the study areas is illustrated in Fig. 1. As summarized in Table 1, a variety of geographic data over the above study area is used in this work. They include 1m res-olution color infrared (CIR) aerial photos, acquired during March and April of 2005 in leaf off conditions, 1.5m resolution DTM impractical without a GIS data management system to organize the data and computations. The real power of GIS is found in the linking of several data sets, analytical models, and interpretation tools (Figure 10). Agricultural users are just beginning to understand and utilize this capability.

Physical entities or phe- nomena arc approximated by data in a GIS. These data include information on the spatial location and extent of the physical entities, and information on their non-spatial proper- Each entity is represented by a spatial Georeferencing is done with a datum. A datum is usually given by a starting point and direction: it specifies where a clearly identifiable point on earth (the base point) should appear on the spheroid and it shows where a base direction, such as north, points on the spheroid at the base point. As all data are characterized by their location, a GIS is the central component within such a software environment. In this context, the basic tasks of a GIS are the administration and visualization of spatial data and their attributes, as well as geocoded pre- and postprocessing of data for 3D analysis, simulation and other hydrogeological evaluations. GIS data is commonly used for managing transportation issues.
