![]() ![]() Interpolating these missing data is an important but difficult problem with high uncertainty. However, when data are missing, large datasets can be rendered entirely unusable, or inadequate for specific applied questions. Open access remote sensing data offer opportunities to tackle many complex and large-scale ecological and conservation questions, from land-use change detection, to quantifying biomass and identifying water quality. Overall we find that our SS-RF method produces accurate estimates under a range of simulated forest clearing scenarios and has a more accurate and robust performance than compositing when modelling noticeably changing landscapes. However, when natural fluctuation occurs and there is minimal change in land cover, compositing has equivalent or more accurate performance than our method. Our method detected forest cover change substantially more accurately than compositing, offering 39% and 12% increases in average overall accuracy for clear felling and tree thinning simulations respectively. Results show our SS-RF method accurately detected simulated land cover change under both clear felling (0.83 average overall accuracy) and tree thinning (0.85 average overall accuracy). Here we present an adaptation of our recent stochastic spatial random forest (SS-RF) method, which combines observed data from a prior image and modelled estimates of the current image to produce interpolated land cover values and associated probabilities of those values. Existing methods for interpolating the missing data based on past images, such as compositing, are effective for stable land cover but can be inaccurate for dynamic and substantially changing landscapes. A challenge of working with satellite images is missing data due to clouds. Due to the prohibitive expense and impracticality of mass field data collection to monitor forest cover at regular intervals, satellite images are a key data source for monitoring forest cover globally. Measuring change in forest cover over time is an essential task in order to track and preserve quality habitats for species around the world. To secure the Pixelaria you can place a sand filled ziplock bag inside the base or install landscape spikes into the holes either on the outside of the base plate or in the two extra holes inside the Pixelaria.Forest cover requires large scale and frequent monitoring as an indicator of biodiversity and progress towards United Nations and World Bank Sustainable Development Goal 15. These will hold the entire assembly together. Now you can find two ziptie holes on the short 4.5″ wide side of the lens that go through the base as well. These holes need to line up with the ones on the base plate. Take note that two corners of the lens have cut outs for the wire to feed in and out. While holding the assembled base plate with pixels installed you can now slide it into the bottom of the clear coro lens. You will also see two corners are cut out to allow the wires to feed in and out. There are slots for the pixel holder to fit into and keep the pixels in place. Now take the base plate with the insert base attached and fold up the four sides. The holder allows for as few as 1 node but can hold up to 15 in a 3×5 matrix. Now take the pixel holder and install however many nodes you want. Place the insert base on the base plate with the cut fold seams facing down and install zipties or hot glue them together. Next take the large flat base plate and the insert base. The short side of the lens should butt to the long side of the lens and set it off to the side. Insert the zipties loosely at first and once you have them all installed you can tighten them up and cut off the extra. First take the clear coro lens and fold the flat lens into the rectangular shape with the cut fold seams to the inside. A Base Plate, Insert Base, Pixel Holder, and Lens. Items sells as a single item or in a set of 12.You will need to furnish pixels or dumb nodes and zipties to assemble the Pixelaria.100% American Made from Material, Design, and Fabrication.Designed for 12mm bullet pixels or dumb RGB nodes.Made from 4mm coro the new Pixelaria provides a great foundation to use for many holidays by adding your own silhouettes. We have designed a solution that allows you to use from 1 to 15 12mm pixel or dumb RGB bullet nodes. The Pixelaria is based on the idea from Blake_l at of a Luminaria bag that used candles to provide that traditional look. The Pixelaria is a modern take on a Luminaria. ![]()
