DESCRIPTION
This map is based on a geographic information system (GIS) analysis of utlity and appraisal records. The density is created in GIS by generating a grid of 100x100 foot cells with a sum of units that fall in the cell, plus units of other cells within a radius, which in this case was a quarter mile. The total count for each cell is divided by the area of the cell, which provides a density. The density can be reported in a number of ways, such as units per acre. Transit is more viable when quarter mile areas around stations have at least 15 units per acre. The image at the bottom right is another way of looking at unit density as if it were expressed in a 3 dimensional view. The higher density areas appear as "mountains" in the city-scape. Data for utilities not served by Austin Electric were not available, so areas outside the service area - which approximates the City's ETJ - are not necessarily depicted correctly.

The purpose of this analysis was to get an overall senseof Austin's unit density and urban form. The information isuseful in a number of ways, and in this case unit density isused to measure the viability of current and proposed railtransit projects. The first step in this analysis was to sumthe number of electric utlity accounts for each addresspoint, and join the information to the point layer. Data forutilities not served by Austin Electric were not available,so areas outside the service area - which approximatesthe City's ETJ - are not necessarily depicted correctly.The density numbers are created by generating a grid ofcells. The GIS program takes each cell and determines acount which includes the count of any points falling intothat cell, plus the sum of counts within a radius, which inthis case was a quarter mile. The total count for each cellis divided by the quarter mile area to determine thedensity. The density can be reported in a number ofways, such as units per acre.Transit is more viable when quarter mile areas aroundstations have at least 15 units per acre. The map showsthat some rail transit routes are or will be supported byadequate densities, while others may need to attractadditional development or redevelopment to enhance thierviability. The image at the bottom right is another way oflooking at unit density as if it were expressed in a 3dimensional view. The higher density areas appear as"mountains" in the city-scape.
