We examined the effects of sampling design on the quality of spatial data collected for a koala citizen science project in Australia. Data were collected from three samples—volunteers (n = 454), an Internet panel (n = 103), and landowners (n = 35)—to assess spatial data quality, a ...
An important consideration in data sampling is the sample's size. In some cases, a small sample is enough to reveal the most important information about the full population. In many cases, however, a larger sample increases the likelihood of accurately representing the population, even though the...
Uncertainty and Context in Geography and GIScience: Reflections on Spatial Autocorrelation, Spatial Sampling, and Health DataFour decades ago, Curry (1972) argued that spatial autocorrelation (i.e., local distance and configuration effects) and distance decay (i.e., global distance effects) ...

encoding model will likely result in overfitting, and that doing so is unlikely to reveal reliable orientation selectivity. However, for high SNR voxels in the NSD dataset used here, we are able to estimate reliable orientation selectivity that improves generalization on out-of-sample data. ...
In a high performance sampled data system a low phase noise crystal oscillator should be used to generate the ADC (or DAC) sampling clock because sampling clock jitter modulates the analog input/output signal and raises the noise and distortion floor. The sampling clock generator should be isolate...
