In Latin the word for 'high mountain' is 'alpes'. As a Vermonter with a love of the outdoors (specifically an affinity for the mountains), I knew from the start of the MGIS program my project would in some way involve mountainous terrain.
This makes the growing season short for most plants. Recorded Trail Ridge Road status: (970) 586-1222. Get … Looking through the images, you can identify areas where I was more or less successful with the mapping, as opposed to interpreting the numbers in the error matrix as the final say for all sections of the study area.In addition to viewing the output in this article, There are a few notes about the files that you should be aware of. However, it is desert-like, with only about 150–250 mm (6–10 in) of precipitation falling per year (the summer is typically the season of maximum precipitation). Tundra … VIEW - THE GREAT NYRG - exploring map by ZEPHYROTTH. For the NDVI representation (a measure of vegetation health in a sense), the important item to note is that the color ramp in the images below ranges from red (low NDVI values, barren areas) to yellow (medium NDVI values, shrub/grassland) to green (high NDVI values, dense/healthy vegetation). photo x 11. folder. During the summer, the permafrost thaws just enough to let plants grow and reproduce, but because the ground below this is frozen, the water cannot sink any lower, and so the water forms the lakes and marshes found during the summer months. This analysis set out to map and delineate alpine tundra, as defined by three feature types: Bare Rock, Alpine Vegetation, and Subalpine Krummholz. All features are highlighted in red boundaries, and each set of images shows four sample features per representation.With the imagery and elevation data sets downloaded and prepared, combined with the knowledge gained from developing the image interpretation key, I moved to the object-based image analysis portion of the project. Though not universal, the ranges observed are directionally accurate (i.e. It is characterized by its high mountains, short plants, and rigid/rough terrain. Research in Alaska has shown fire-event return intervals (FRIs) that typically vary from 150 to 200 years, with dryer lowland areas burning more frequently than wetter highland areas.Due to the harsh climate of Arctic tundra, regions of this kind have seen little human activity, even though they are sometimes rich in natural resources such as Another concern is that about one third of the world's soil-bound carbon is in The amount of greenhouse gases which will be released under projected scenarios for global warming have not been reliably quantified by scientific studies.In locations where dead vegetation and peat has accumulated, there is a risk of wildfire, such as the 1,039 kmAntarctic tundra occurs on Antarctica and on several Antarctic and subantarctic islands, including The flora and fauna of Antarctica and the Antarctic Islands (south of 60° south latitude) are protected by the Alpine tundra does not contain trees because the climate and soils at high altitude block tree growth. To better show the qualitative comparison, I created a series of six images along different parts of Mount Mansfield that compare the imagery basemap to the output shapefile.My personal opinion is that the qualitative comparison provides a better assessment of how well (or not well) I mapped the alpine tundra. Tundra Climate and Effects of Global Warming. Other feature types include:In order to scope my analysis and focus on the features of interest, I grouped all other features into a class named Other.The image below shows the four stages and the major components of each stage.I obtained all imagery and elevation data sets for this project from the Imagery data sets (sampled in the image below) included:Note that all of the imagery data sets contained four spectral bands (at the spatial resolutions listed above): Red, Green, Blue, and Infrared.Elevation data sets (sampled in the image below) included:When conducting remote sensing studies where you are trying to extract features, it is useful to follow the The following set of images shows the visual part of my image interpretation key (there is also a written part) for the features of interest in True Color imagery (Red/Green/Blue bands), Color Infrared imagery (Infrared/Red/Green bands), and the Normalized Difference Vegetation Index (NDVI) representations.
