Green areas are Walkable

Yellow, Orange, and Red areas are Bikeable

Walkable areas

Honolulu


Can handle 80% of housing demand

3D Analysis - GeoProcessing: Surface Analysis Conversions Feature-oriented Analysis

o New at ArcGIS 10 w/ additions at 10.1 & 10.2

Prepare data for visualization/analysis Performing surface/feature 3D analysis General GeoProcessing:

Batch/non-interactive data processingHigher level functions over ArcObjects

Line of Sight

How much of the road can be seen from these camera / observer locations?

Quick assessment of visibility between features using geo-processing tools.

Line of Sight

How much of the sky is obstructed by this proposed building? Does it violate our planning ordinances?

Summarized assessment of % of viewable sky, based on line of sight tools.

Cumulative Line of Sight

How visible are these buildings to the surrounding area?

Cumulative line of sight analysis, with visual prominence / quality.

Cumulative Line of Sight

Improved Streets

View assessment

Improved StreetsVisual Prominence

Visual Connectivity

Skyline and Skyline Barrier

Which buildings define our skyline? How high can we build without changing our skyline?

Intersect sample points with a surface created using skyline barrier, then using it to generate a buildable volume.

Intervisibility

Line of sight

Demo: Sky occlusion

Shadows and shadow maps

Where do shadows fall? How can we quantify their impact over time?

Intersection of shadows, at specified time intervals, for specified days in the year, on a park polygon.

Glare estimation

Where, roughly, will sun reflected off this proposed building fall.

3D intersection to extract faces in shade, then skyline volumes are used to simulate light volumes.

Built Environment

Legal Environment

Defines restrictions on land useLand use zones, property ownership boundaries, regulations

Natural Environment
