CONTEXT Topographic Data

Santa Cruz Island, California Santa Cruz Island is located off the coast of Southern California and is part of the Channel Islands archipelago. It’s the largest of the Channel Islands and is known for its sea caves, beautiful hiking trails, coves, cliffs, and beaches. The island was originally settled by the Chumash people, and is now a privately owned National Park and nature conservancy.

CONTEXT Climate
Southern California is known for its sunny days and almost perfect weather year round. The charts above illustrate the months which experience the most sun, wind, and rain. Santa Cruz island experiences something called the Santa Ana winds periodically throughout the year (mainly in September through December). These are high velocity winds which bring about high temperatures and low humidities.

Average Temperatures and Percipitation Santa Cruz Island experiences very moderate year round temperatures and is said to have a Mediterranean-type climate. It has cool, wet winters and hot, dry summers with an annual rainfall of 8-40�. The climate is moderated by the marine influence which makes summers mild, humidity high, and produces a frequent nocturnal fog.

CONTEXT Analysis conclusions
Conclusions Moving forward with our analysis, we have decided that the the contours provides the most potential for an interesting geometrization of the topography. These zoomed-views of the slope analysis show the extremes in areas of the land.

Topo-system Inspiration
Coral Reefs The geometrization of our topography is based on rocks of which coral reefs inhabit. Sea rocks have many holes, divits, terraces, and other variations in texture, which is what we tried to abstract and recreate in the Santa Cruz topography.

Topo-system Geometrization
Voronoi We used the voronoi system to transform the topography into an abstracted version of sea reef rock-like geometries. Voronoi is a system of geometric shapes that partitions a plane into different regions using points. It simplifies the curvature and contours of the topography in order to transform them into 3D geometric shapes with more malleable data.

Topo-system Geometrization
Voronoi Through the runoff analysis, we learned about the curvature of the topography. In comparison to a flat ground plane where the topography is dramatically convex we have created terraces and where it is dramatically concave we created ponds. We used the virgin landscape between the two extremes in order to maintain some of the original topography.

Topo-system System layers
VIRGIN LANDSCAPE
TERRACES
PONDS
System Layers The topography system has three layers to it: ponds, terraces and the virgin landscape. The ponds are classified as voronoi cells which dip down into the landscape based on low-sloped curvature in the topography. Terraces are steps on the ladscape which are based on high-sloped curvature in the topography. The virgin landscape is untouched areas of the original topography.

Topo-system System components
Component Variations Terraces and ponds are the only components that have visible variations throughout the topography. Terraces vary in height and amount of sides depending on the slope of the land. Ponds vary in depth and amount of sides also depending on slope. The virgin landscape has an invisible voronoi net over it, creating cells of land. These cells also vary in side amount but it can’t be seen.

Topo-system Geometrization
Highlighted Zooms These zooms show detailed images of the geometrized topography with sun. They make height differences between terraces clearer as well as depths of ponds. Some voronoi indentations can be seen in the virgin landscape which shows how the ponds and terraces were formed.

Topo-system Analysis
Component Assignments These images show how the components were assigned to the landscape. Red areas are considered to be of a high slope, and are given terraces. Orange areas are a bit lower of a slope, so they recieve a lower terrace. Yellow is a flater slope, so the topography remains the same. Blue is the lowest of the slopes, and gets ponds. Size of ponds increases as the slope flattens.

Arch-system Inspiration
Sea Coral The structure designed to sit on top of the topography is inspired by sea coral. The topography mimics the rock of a coral reef and the structure is the coral itself. The structure is representative of different types of sea coral and how they grow and attach themselves to the reef rock.

Arch-system Geometrization
Triangulation Centerpoints of certain ponds and terraced voronoi cells are exrtruded upward which creates a net of triangulated structure. Some nets connect more than others depending on the slope of the terrace or pond. The centerpoints of the cells connect with other nearby points, turning them in vertices for the triangulated structure.

Arch-system Geometrization
Triangulation The thicker triangulated net can be seen at the lowest points of the topography on top of the ponds. As the z-distance increases, the nets begin to thin out and become more skeletal. Nets on top of ponds are separated from nets on top of terraces. The smaller nets are a result of a smaller terrace or pond cluster of which they sit on.

Large structure with thicker netting
Small skeletal structure
Structure Components The structure only has one main component with different variations in thickness and size. The thicker the net, the lower it’s located on the topography. The higher the location, the more skeletal the structure becomes. The size of the structure depends on the size of the cluster or pond that it sits on.
