Sampling Prospect Park, Describing Prospect Park (016)

Sampling Prospect Park, Describing Prospect Park (live link) represents four ways of sampling elevation and two ways of describing it. Points are first differentiated by sampling method. Then, on hover, points are culled and associated in a different way: by corresponding height.

Continuous paths become fragmented, while neighbors in plan are found to have different neighbors in section. Points that were once similar are now different.

Points within a +/- 2ft range from all sampling groups are isolated. The following data sources were used: points sampled from a raster DEM (USGS 1m) at set intervals; points recorded with a GPS data logger at approximately set intervals; points recorded along a path every 12 seconds with a GPS data logger; and points sampled from spot elevations, at the highest part of a building or feature, captured by New York City. All points are located by satellite — in one way or another — and are distinct only in what was chosen to be identified by elevation.

Additional information on the data collection process is detailed in the post, “Field Data Collection (001): Prospect Park Walk“.

Next Steps:

• Explore whether all sampling methods should have the same representation on hover, or maintain their previous shape and color.
