Remotely sensed data – available at medium to high resolution across global spatial and temporal scales – are a valuable resource for ecologists. In particu- lar, products from NASA’s MODerate-resolution Imaging Spectroradiometer (MODIS), providing twice-daily global coverage, have been widely used for eco- logical applications. We present MODISTools, an R package designed to improve the accessing, downloading, and processing of remotely sensed MODIS data. MODISTools automates the process of data downloading and processing from any number of locations, time periods, and MODIS products. This auto- mation reduces the risk of human error, and the researcher effort required compared to manual per-location downloads. The package will be particularly useful for ecological studies that include multiple sites, such as meta-analyses, observation networks, and globally distributed experiments. We give examples of the simple, reproducible workflow that MODISTools provides and of the checks that are carried out in the process. The end product is in a format that is amenable to statistical modeling. We analyzed the relationship between spe- cies richness across multiple higher taxa observed at 526 sites in temperate for- ests and vegetation indices, measures of aboveground net primary productivity. We downloaded MODIS derived vegetation index time series for each location where the species richness had been sampled, and summarized the data into three measures: maximum time-series value, temporal mean, and temporal vari- ability. On average, species richness covaried positively with our vegetation index measures. Different higher taxa show different positive relationships with vegetation indices. Models had high R2 values, suggesting higher taxon identity and a gradient of vegetation index together explain most of the variation in species richness in our data. MODISTools can be used on Windows, Mac, and Linux platforms, and is available from CRAN and GitHub (https://github.com/ seantuck12/MODISTools).
Awesome new (ish?) R package from the gang over at rOpenSci
Tired of searching biodiversity occurance data through individual platforms? The "spocc" package comes to your rescue and allows for a streamlined workflow in the collection and mapping of species occurrence data from range of sites including: GBIF, iNaturalist, Ecoengine, AntWeb, eBird, and USGS's BISON.
There is a caveat however, since the sites use alot of the same repositories the authors of the package caution to check for dulicates. Regardless what a great way to simplify your workflow!
Find the package from CRAN: install.packages("spocc") and read more about it here!/span>
Turf provides you with functions like calculating buffers and areas. Other common functions include aggregation, measurement, transformation, data filtering, interpolation, joining features, and classification. The detailed explanations of these functions can be found on this page.
Turf seems like a cool tool to try out if you want to provide spatial analysis functions on your webGIS applications.
Technical Tidbits From Spatial Analysis & Data Science. This nice blog highlights many technical aspects of web mapping: Leaflet, D3, R... lots of neat examples.
Thanks to Dave Thau, Karin Tuxen-Bettman, John Bailey, and Emily Henderson who came to visit the GIF and give a demo of the GEE toolbox. We went over the guts of GEE, Timelapse (very cool: make your own! Here is mine), the GEE GUI framework, and the GEE API. Very fun afternoon!
