However, metrics at time points fail to quantify a time interval\\u2019s gross change, which can be substantially larger than net change between two time points. The field of landscape ecology has lacked a conceptual framework and accompanying software to characterize patterns of gross change during time intervals in terms of patches that are spatially explicit with a typology that is mutually exclusive and collectively exhaustive.&lt;\\\/p&gt;\\n&lt;p&gt;Objectives&lt;\\\/p&gt;\\n&lt;p&gt;We present a new method and software named &lt;strong&gt;Dynamic&lt;\\\/strong&gt; &lt;strong&gt;PA&lt;\\\/strong&gt;tch &lt;strong&gt;T&lt;\\\/strong&gt;ransition &lt;strong&gt;CH&lt;\\\/strong&gt;aracterization in explicit space (DynamicPATCH). DynamicPATCH reads a time series of raster maps of a Boolean variable to map, characterize, and quantify gross patch dynamics in ways that existing metrics miss. We design the method to compare time intervals that vary in their durations.&lt;\\\/p&gt;\\n&lt;p&gt;Methods&lt;\\\/p&gt;\\n&lt;p&gt;Our method identifies eight patch-based transition types that are mutually exclusive and collectively exhaustive: Disappearing, Appearing, Splitting, Merging, Perforating, Filling, Contracting, and Expanding. The method quantifies each type\\u2019s gross gain and gross loss in area. The method also shows how each type contributes to the gross increase and gross decrease in the number of patches during each time interval. We illustrate our method with a simple example as well as a case study on the dynamics of Marshes and Ponds in the Plum Island Ecosystems site of the National Science Foundation\\u2019s Long Term Ecological Research network (PIE-LTER) across the years 1938, 1971, and 2013.&lt;\\\/p&gt;\\n&lt;p&gt;Results&lt;\\\/p&gt;\\n&lt;p&gt;Our method reveals dramatic gross changes in the size and number of patches of Pond and Marsh at PIE-LTER, which traditional methods that report only net changes fail to capture. The transition types Perforating and Contracting account for 89% of gross loss in Marsh size across the temporal extent. Annual gross increase in the number of Marsh patches during the second time interval is 3.8 times greater than during the first time interval, with 40% of gross increase contributed by Appearing and 60% by Splitting. Gross gain of Pond is more than twice the size of gross loss of Pond, with Merging accounting for 47% of gross gain, followed by Appearing and Expanding. Appearing and Disappearing account for most gross changes in the number of Ponds during the temporal extent, which is ten times greater than the net change in the number of Ponds.&lt;\\\/p&gt;\\n&lt;p&gt;Conclusions&lt;\\\/p&gt;\\n&lt;p&gt;DynamicPATCH offers a new operationalized approach to characterize the spatial-temporal patterns of patch dynamics. DynamicPATCH can be applied to various landscapes to pursue important research agendas in landscape ecology, such as landscape fragmentation, habitat connectivity, process-pattern relationships, and more.

We present here a new method for a robust assessment of land cover transitions over time and apply this methodology to the yearly MapBiomas land use land cover maps of Brazil spanning 1985 to 2022. Based on a reference sample of 85,152 points, we find MapBiomas to have limited accuracy as an indicator of yearly land use change, but consistent over the full mapping period. Alternation, a newly defined error component, derives from where one location experiences multiple changes during the time series. It is the primary reason for differences in estimates of annual change and is 4.6 times more frequent in the MapBiomas product than reference data. Over the full time period analyzed, the annual land use change area decreases for both the MapBiomas classification and reference data. The total land use changes detected over the 37 year study period are 232 million hectares and 252 million hectares for the reference data and MapBiomas product, or 27% and 29% of the Brazilian territory respectively.&lt;\\\/span&gt;&lt;\\\/p&gt;\",\"Include description in output citation\":1,\"Origin\":\"Manual\"},\"facultyid\":\"C11301315\",\"status\":[{\"id\":12415,\"status\":\"Revise &amp; Resubmit\",\"term\":\"Summer\",\"year\":2025,\"termid\":\"2024\\\/05\",\"listingorder\":3,\"completionorder\":3},{\"id\":12415,\"status\":\"Completed\\\/Published\",\"term\":\"Summer\",\"year\":2025,\"termid\":\"2024\\\/05\",\"listingorder\":6,\"completionorder\":6}],\"userid\":\"C11301315\",\"attachments\":[{\"attachmentid\":13567,\"mimetype\":\"custom\\\/url\",\"filename\":\"https:\\\/\\\/www.tandfonline.com\\\/doi\\\/full\\\/10.1080\\\/17538947.2025.2528604\",\"filesize\":452448,\"downloadurl\":\"https:\\\/\\\/faculty180.interfolio.com\\\/public\\\/download.php?key=SDRwNCtxSUpsamxBQ213WS9ucHFuNnMwT0hzQU11b2RPQkJ2cWc3amxyUmNRdVVXTkF4MU10Q1FvdGN3MEZPOWxLQytxSXV3YUNZTmNTR0tYR29Id1crNS9XV2tLdDlTNGc1dno0aVlWMW9DQnNNcEtOSVQzM3hUcThpR2RQVlVHVHlaSiszQ0pWcGdhUmg1U3VvTU5Ibk1pVmFxT1hjc1FCOXZEWDhNRU5zZWx5NmhON0RrUG03TU1tV0ZLUnpFZkxGTitYamVXMm89\"}],\"coauthors_list\":[\"Ana Paula Matos\",\"Maria Hunter\",\"Robert G.

Authors should report disagreement components that relate to the research question, without anointing results as acceptable or good. This manuscript reviews the citations of the 2011 manuscript entitled \\u2018Death to Kappa: Birth of Quantity Disagreement and Allocation Disagreement for Accuracy Assessment\\u2019, which gave two recommendations: (1) do not use Kappa and (2) use disagreement components. We analyzed 200 articles that cited the Death to Kappa manuscript. A quarter of the articles followed both recommendations, another quarter fol\\u00ad lowed only the first recommendation, another quarter followed only the second recommendation, and the last quarter followed neither recommendation. The attempt to replace Kappa with disagreement components has been partially effective, while Kappa continues to haunt several professions. We discuss misguided uses of Percent Correct and Kappa in Remote Sensing and Land Change Modeling. The concepts are general and thus relate to additional fields. Authors frequently use arbitrary thresholds of metrics to claim that results are acceptable. However, the notion that results can be acceptable or not is inherently unscientific. Scientists must use a metric that addresses a clear research question in which the scien\\u00adtists have no vested interest in the results.\",\"Include description in output citation\":1,\"Origin\":\"Manual\"},\"facultyid\":\"C11301315\",\"status\":[{\"id\":12411,\"status\":\"Completed\\\/Published\",\"term\":\"Spring\",\"year\":2025,\"termid\":\"2024\\\/03\",\"listingorder\":6,\"completionorder\":6}],\"userid\":\"C11301315\",\"attachments\":[{\"attachmentid\":10926,\"mimetype\":\"application\\\/pdf\",\"filename\":\"Pontius Jr et al. - 2025 - A call to interpret disagreement components during.pdf\",\"filesize\":1929516,\"downloadurl\":\"https:\\\/\\\/faculty180.interfolio.com\\\/public\\\/download.php?key=SDRwNCtxSUpsamxBQ213WS9ucHFuNnMwT0hzQU11b2RPQkJ2cWc3amxyUmNRdVVXTkF4MU10Q1FvdGN3MEZPOUNHVURvZmMzUmM4MitaQnZwaFYrVTFtMTY0N21pRUZCVHFUb2FUaEY4d0RoYktONFd4RVdtT01DUkZvUVBnSnlTdHZUYnk0dmNDRC85ZFFaaGloTUlzVW5iQnVIU0s4UDNUclZCc0dQOGV2RjFIRnB2MHhvS2toSC81NnhUN21ZSTJNYy9MWG80cTg9\"}],\"coauthors_list\":[\"Robert G.

TOC curves reveal the sizes of the four entries in the confusion matrix at each threshold, which make TOC curves more easily interpretable than ROC curves. The TOC has become popular, especially to assess the fit of simulation models to predict land change. However, the literature has shown variation in how authors apply and interpret the TOC, creating some misleading conclusions. Our manuscript lists best practices when applying and interpreting the TOC to help scientists learn from TOC curves. An example illustrates these practices by applying the TOC to measure the ability to predict the gain of crop in Western Bahia, Brazil. The application compares four ways to design the rank variable based on the distance to either pixels or patches of either the presence or change of crop. The results show that the gain of crop during the validation time interval is more strongly associated with the distance to patches rather than pixels of crop. The Discussion Section reveals that if authors show the TOC curves, then readers can interpret the results in ways that the authors might have missed. The Conclusion encourages scientists to follow best practices to learn the wealth of information that the TOC reveals.\",\"Include description in output citation\":1,\"Origin\":\"Manual\"},\"facultyid\":\"C11301315\",\"status\":[{\"id\":12412,\"status\":\"Completed\\\/Published\",\"term\":\"Spring\",\"year\":2025,\"termid\":\"2024\\\/03\",\"listingorder\":6,\"completionorder\":6}],\"userid\":\"C11301315\",\"attachments\":[{\"attachmentid\":10927,\"mimetype\":\"application\\\/pdf\",\"filename\":\"Honnef and Pontius Jr - 2025 - Best Practices for Applying and Interpreting the T.pdf\",\"filesize\":4503809,\"downloadurl\":\"https:\\\/\\\/faculty180.interfolio.com\\\/public\\\/download.php?key=SDRwNCtxSUpsamxBQ213WS9ucHFuNnMwT0hzQU11b2RPQkJ2cWc3amxyUmNRdVVXTkF4MU10Q1FvdGN3MEZPOUNHVURvZmMzUmMvdENrL1RmZStsM3gvMHR4dVJGRWRwb1VlZENKdXVwNEErUDkvcDQ0THloRUIyT2N0NDgwNC9OY3lUQWxhcDJGRk8wVmZ0S0NVNUZhRzV1enYxZ0tUdGJwVUF4eXk2K0JBR00xYWovTkVOSFpyVnJXWVJna0FpYkdaS0ZjWjZTaVk9\"}],\"coauthors_list\":[\"Tanner Honnef\",\"Robert G.

Trajectory Analysis produces maps and bar graphs that help to visualize hotspots and hot moments of change. The method computes up to eight trajectories and three components of change: Quantity, Exchange, and Alternation. Quantity is the non-spatial absolute net change between the two time points that bound the temporal extent. Exchange is the additional spatial gross change between those two time points. Alternation is the additional temporal gross change that reverses itself during the sequence of time intervals, such as gross gain followed by gross loss at the same location. Alternation shrinks through coarser temporal resolutions to reflect the durations between gross gains and gross losses. An application illustrates the concepts by analyzing soybean cultivation during annual time intervals from 1989 to 2021 in Western Bahia, Brazil. The largest component of change at temporal resolutions of fewer than four years for our case study is Alternation, which is a pattern that popular methods miss.

Scientists need new methods to summarize the temporal changes so scientists can understand broad patterns and have guidance for how to look deeper into particular places, trajectories, classes, and time intervals. Our manuscript addresses this need by presenting an innovative method that summarizes the temporal changes in terms of a map of four trajectories and bar charts of five components: quantity, allocation exchange, allocation shift, alternation exchange, and alternation shift. An application illustrates the method using 16 land cover classes at 7 time points from 1990 to 2020 in western Bahia, Brazil. Results reveal a substantial component of alternation shift, which exists when pixels transition from savanna to temporary crops to soybean.

To fill this gap, this article introduces the Bayesian Operating Characteristic (BOC) curve, a novel explanatory framework derived from the application of Bayes\\u2019 theorem and numerical analysis on the TOC curve. Such a framework establishes the computation of cumulative and density distribution functions that describe and identify non-linear relations between a rank variable and its binary outcome, specifying the rank\\u2019s interval with the maximal positive or negative impact in the classification. The proposal is validated by the analysis and identification of urban land change drivers, revealing different non-linear probabilistic relationships between rank variables and the binary outcome.&lt;\\\/span&gt;&lt;\\\/p&gt;\",\"Include description in output citation\":1,\"Origin\":\"Manual\"},\"facultyid\":\"C11301315\",\"status\":[{\"id\":12417,\"status\":\"Completed\\\/Published\",\"term\":\"Fall\",\"year\":2025,\"termid\":\"2025\\\/01\",\"listingorder\":6,\"completionorder\":6},{\"id\":12417,\"status\":\"Submitted\",\"term\":\"Spring\",\"year\":2025,\"termid\":\"2024\\\/03\",\"listingorder\":2,\"completionorder\":2}],\"userid\":\"C11301315\",\"attachments\":[{\"attachmentid\":13569,\"mimetype\":\"custom\\\/url\",\"filename\":\"https:\\\/\\\/www.sciencedirect.com\\\/science\\\/article\\\/abs\\\/pii\\\/S136481522500372X?via%3Dihub\",\"filesize\":452448,\"downloadurl\":\"https:\\\/\\\/faculty180.interfolio.com\\\/public\\\/download.php?key=SDRwNCtxSUpsamxBQ213WS9ucHFuNnMwT0hzQU11b2RPQkJ2cWc3amxyUmNRdVVXTkF4MU10Q1FvdGN3MEZPOWxLQytxSXV3YUNZTmNTR0tYR29Id1crNS9XV2tLdDlTNGc1dno0aVlWMW9FZVlzenNEV3dnTzdSbzNVSy8wcDRpSzJSQ1lFREJaZ2VNTFNuM0J2M2VoNHNCMGFZSlhEZ1hNSTQ4ZVVWVGZMUitobGZTZHAxUlFzemhtRjNYR3VHU3Y0Vjd4V041NmNiSlU4U3dFNFU1UXdMTDBxMG9IdG4%3D\"}],\"coauthors_list\":[\"Rodrigo Lopez-Farias\",\"S.

The illustrative variable is the marsh landcover category in the Plum Island Ecosystems of northeastern Massachusetts, USA. The data are an elevation map and maps showing the land categories of water, marsh, and upland in 1938, 1971, and 2013. There were losses and gains near the edge of the marsh between 1938 and 1972 and between 1972 and 2013. The TOC curves show that marsh gained most intensively at intermediate elevations during the first time interval and then had a weaker association with elevation during the second time interval. Marsh gains more intensively from water than from upland during both time intervals. The TOC curves also demonstrate that the marsh gains occurred where marsh was previously lost, a phenomenon called Alternation. Furthermore, eliminating far distances and extreme elevations from the spatial extent decreased the area under the curve (AUC) for distance and increased the AUC for elevation. We invite scientists to use the TOC because the TOC is easier to interpret and shows more information than the Relative Operative Characteristic.\",\"Include description in output citation\":1,\"Origin\":\"Manual\"},\"facultyid\":\"C11301315\",\"status\":[{\"id\":12410,\"status\":\"Completed\\\/Published\",\"term\":\"Summer\",\"year\":2024,\"termid\":\"2023\\\/05\",\"listingorder\":6,\"completionorder\":6}],\"userid\":\"C11301315\",\"attachments\":[{\"attachmentid\":10925,\"mimetype\":\"application\\\/pdf\",\"filename\":\"Bilintoh et al. - 2024 - Analyzing the Losses and Gains of a Land Category.pdf\",\"filesize\":7168508,\"downloadurl\":\"https:\\\/\\\/faculty180.interfolio.com\\\/public\\\/download.php?key=SDRwNCtxSUpsamxBQ213WS9ucHFuNnMwT0hzQU11b2RPQkJ2cWc3amxyUmNRdVVXTkF4MU10Q1FvdGN3MEZPOUNHVURvZmMzUmMvdFpSU3Uva2s2K3YrNHFxa1oyZ2poU2hvaGJlZnBxbkw5U1R3UVNCVHN6VnpNV0lpZkFmb25ZMklicWw0QnFIZEFONWl3MFBhZThXVzNkZDMzQitvUkZuUndidlBDY0pBeEYwRkQ5c0RjallTb1dURmZQMEpi\"}],\"coauthors_list\":[\"Thomas Mumuni Bilintoh\",\"Robert G.

The methods include an option to facilitate comparison among sites by expressing results as an annual percentage of each site\\u2019s unified size. A site\\u2019s unified size is the union of where the category exists at any of the site\\u2019s time points. The methods also specify gross losses, gross gains, eight trajectories, and three compo\\u00ad nents: Quantity, Exchange, and Alternation. The illustrative application compares maps of the marsh category for three Long-Term Ecological Research sites: Plum Island Ecosystems (PIE), Georgia Coastal Ecosystems (GCE), and the Virginia Coast Reserve (VCR). The application analyzes marsh\\u2019s changes during two time intervals that have unequal durations within each site\\u2019s distinct temporal extent. Results show that PIE has the fastest change during each site\\u2019s temporal extent. Gross change is more than double the quantity change for all sites. Exchange accounts for most of the change in GCE, while Alternation accounts for most of the change in PIE and VCR.

The paper\\u2019s title indicates its two recommendations: 1 do not use kappa and 2 use components of disagreement to assess errors. We analyzed 200 articles to see how authors cited the Death to Kappa paper, which has more than 2000 citations. Results show that a quarter of the articles followed both recommendations, another quarter of the articles followed only the first recommendation, another quarter of the articles followed only the second recommendation, and the last quarter of the articles followed neither recommendation. Thus, the attempt to kill kappa and to replace kappa with more enlightening metrics has been partially effective, but kappa continues to haunt our profession. This webinar discusses and illustrates persistent bad habits concerning how authors use metrics in Remote Sensing and Land Change Modeling that were not covered in the 2011 paper.
