GIS 5 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Network Analyst Solves a variety of problems based on geographic networks including: Most efficient travel routes Travel directions Closest emergency vehicle or service facility to an incident Service areas or sales territories based on travel time
6
GIS 6 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Delivery Route - This path represents a delivery truck route. - With the Network Analyst, the dispatcher can define a route that with stop at each restaurant in the most efficient order and return to the warehouse.
7
GIS 7 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Shortest and Fastest Path -This path represents the shortest linear distance between the two locations. - This path represents the fastest path between the same two locations used in the previous example. - Fastest paths are based on time. You can use any measure of time ( seconds, minutes, hours, etc.)
8
GIS 8 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Service Areas - Overlapping and nested service areas are individual polygons. - This allows you to use ArcView's spatial analysis tools to determine which customers or how many customers are in each service area or if any customers are serviced by more than one site.
9
GIS 9 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Areas within a Distance This example shows which areas are within a 10 minute walking distance of different bus stops (service area and network) and which bus routes (find best route) are serviced by the stops.

GIS 10 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Spatial Analyst Grid based layers Geographic data to attempt to describe, simulate or predict a real-world problem or system Creates continuous surfaces from scattered point features Maps easy to read
11
GIS 11 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Grid Layers Divides geographic space into uniform blocks called cells - Every cell represents a certain specified portion of the earth, such as a square kilometer or square meter - Each cell is given a value that describes the site, such as elevation or landuse type

15
GIS 15 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Hydrology Maps Flow direction grid from an elevation grid Hypothetical spill points, shown by white dots, on the elevation grid. Spatial Analyst uses the flow direction and elevation values to compute the contaminant's probable downhill path.

GIS 18 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Surface Model A geographic surface, or surface model, represents a spatial quantity or phenomenon that can be measured continuously over some part of the earth Terrain Elevations DEM - Digital Elevation Model DTM - Digital Terrain Model
19
GIS 19 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Other Surface Examples Geographic phenomena - Soil type - Land cover - Temperature - Rainfall - Population density
20
GIS 20 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Surface Model (Elevations) Sample elevation points that can be used to generate a surface model. A set of sample elevation points. Each point has x,y values and a z value, which defines its elevation.
21
GIS 21 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Surface Model (Elevations) A surface model generated from the points and displayed in 3D perspective.
22
GIS 22 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Grids A grid defines geographic space as a matrix of identically-sized square cells. Each cell holds a numeric value that measures a geographic attribute (like elevation) for that unit of space. When the grid is drawn as a map, cells are assigned colors according to their numeric values.
23
GIS 23 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Grids A grid divides geographic space into cells of equal size. Each cell stores a number that measures a geographic value at that location. In this case, the numbers reflect elevation in meters.
24
GIS 24 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Grids An elevation grid drawn in a view. The cell values are classified by numeric range and symbolized with different colors.
25
GIS 25 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University Grid Example Proposed shopping center plan displayed on a graded elevation surface
26
GIS 26 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University TIN (Triangulated Irregular Network) A TIN is a data structure that defines geographic space as a set of contiguous, non- overlapping triangles, which vary in size and angular proportion.
27
GIS 27 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University TIN Structure Defined by two elements: a set of input points with x,y, and z values, and a series of edges connecting these points to form triangles. Each input point becomes the node of a triangle in the TIN structure, and the output is a continuous faceted surface of triangles.
28
GIS 28 Copyright 2005 – Kristen S. Kurland, Carnegie Mellon University TIN The TIN structure, showing nodes (sample elevation points) and the triangles generated from them.

In addition, a regional elevation model was used to assess the impact of development on the visibility of important landscape features. This information was used to help the city, property owners, and the public understand what would be allowed under the proposed plan.
