This paper establishes some simple statistical tests to be applied to NDVI-derived time series of remotely sensed data products. Specifically, the methods determine the statistical significance of three separate metrics of the persistence of vegetation cover or changes within a landscape by comparison to various forms of \u201cbenchmarks\u201d; directional persistence (changes in sign relative to some fixed reference value), relative directional persistence (changes in sign relative to the preceding value), and massive persistence (changes in magnitude relative to the preceding value). Null hypotheses are developed on the basis of serially independent, normally distributed random variables. Critical values are established theoretically through consideration of the numeric properties of those variables, application of extensive Monte Carlo simulations, and parallels to random walk processes. Monthly pixel-level NDVI values for the state of Florida are analyzed over 25 years, illustrating the techniques\u2019 abilities to identify areas and\/or times of significant change, and facilitate a more detailed understanding of this landscape. The potential power and utility of such techniques is diverse within the area of remote sensing studies and Land Change Science, especially in the context of global change.<\/jats:p>","DOI":"10.3390\/rs6054473","type":"journal-article","created":{"date-parts":[[2014,5,14]],"date-time":"2014-05-14T11:22:27Z","timestamp":1400066547000},"page":"4473-4497","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["Time Series Analysis of Land Cover Change: Developing Statistical Tools to Determine Significance of Land Cover Changes in Persistence Analyses"],"prefix":"10.3390","volume":"6","author":[{"given":"Peter","family":"Waylen","sequence":"first","affiliation":[{"name":"Department of Geography, University of Florida, TUR 3129, Gainesville, FL 32611, USA"}]},{"given":"Jane","family":"Southworth","sequence":"additional","affiliation":[{"name":"Department of Geography, University of Florida, TUR 3129, Gainesville, FL 32611, USA"}]},{"given":"Cerian","family":"Gibbes","sequence":"additional","affiliation":[{"name":"Department of Geography and Environmental Studies, University of Colorado, Colorado Springs, 1420 Austin Bluffs Parkway, Colorado Springs, CO 80918, USA"}]},{"given":"Huiping","family":"Tsai","sequence":"additional","affiliation":[{"name":"Department of Geography, University of Florida, TUR 3129, Gainesville, FL 32611, USA"}]}],"member":"1968","published-online":{"date-parts":[[2014,5,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2111","DOI":"10.1016\/j.rse.2010.04.016","article-title":"Dryland observation at local and regional scale-comparison of Landsat TM\/ETM+ and NOAA AVHRR time series","volume":"114","author":"Stellmes","year":"2010","journal-title":"Remote Sens.
