H13V11+Southern+Brazil

Landsat Atmospheric Correction (All Landsat Data in the link above)



The three maps, displayed below, demonstrate Southern Brazil’s vegetation change for spring, summer and fall or 2010. The maps are utilizing the NDVI, Normalized Difference Index, helping determine vegetation. Before going further note that there is a difference in seasons between Brazil and the U.S. for the purpose of making these maps for class, based in the U.S. and explanation must be in place. For what we consider to be spring in America is not in Brazil; however this change was not made in the maps created below. So what I’m trying to say is that the seasons listed on the maps are not Brazil’s season, the following will explain: U.S spring is Brazil’s summer U.S summer is Brazil’s winter U.S Fall is Brazil’s summer

For what is titled to be Spring Vegetation Change is actually Brazil’s summer, were there is much rain and humidity. Further instated in the map, were the majority of the vegetation is healthy vegetation represented by the high elevation. Low elevations indicate dry vegetation, which is minimal for this particular season. Summer is Brazil’s fall and winter, where not much rain occurs but temperatures due drop. This again is evident in the map; mid elevations is more dominant meaning it is dryer due to the lack of rain and humidity. This also explains an increase in dry vegetation along the coast, represented by low elevations. Due to the drop in temperature in Brazil during this season there is still a good amount of high levels of healthy vegetation. For fall, Brazil’s spring, it is evident that temperatures increase throughout the area. Mid elevations indicate that the somewhat drier vegetation has spread along the tile. Also evident by the higher elevations which represent healthy vegetation has decreased in area.

**Comments from Kirsten: if you scale your data from 0 to 1, you will see more depth in your vegetated areas.**







Lab4:

1. The Anthromes file has 184 Columns, 121 Lines, and 1Band; while the MODIS Time Series has 305 Columns, 201 Lines, and 120 Bands.

2. The MODIS Time Series has more Columns, Lines, and Bands than the Anthromes file; due to the difference in resolutions, they are different. It has 120 time steps, 16 days per composites and there are 23 composites per observations. 3. It would be wrong to shrink the Anthrome pixels because in doing so it will make it harder to verify the classification.

From most to least, the five most dominant classes are as follows:

<span style="font-family: 'Garamond','serif'; margin: 0in 0in 10pt;">1. Class #32, Residential Rainedfed Mosaic, with 5,179 points <span style="font-family: 'Garamond','serif'; margin: 0in 0in 10pt;">2. Class #42, Populated rangeleands, with 2,848 points <span style="font-family: 'Garamond','serif'; margin: 0in 0in 10pt;">3. Class #34, Populted rainfed Cropland, with 2,159 points <span style="font-family: 'Garamond','serif'; line-height: normal; margin: 0in 0in 0pt;">4. Class #51, Populated forests, with 1,815 points

<span style="font-family: 'Garamond','serif'; line-height: normal; margin: 0in 0in 0pt;">5. Class #41, Residential rangelands, with 1,734 points

<span style="font-family: 'Garamond','serif'; line-height: normal; margin: 0in 0in 0pt 0.5in; text-indent: -0.25in;">4. 61.69% of the area is covered by the five most dominant classes.

<span style="font-family: 'Garamond','serif'; line-height: normal; margin: 0in 0in 0pt 0.5in; text-indent: -0.25in;">



<span style="font-family: 'Garamond','serif'; line-height: normal; margin: 0in 0in 0pt; text-indent: 0.25in;">5-8. <span style="font-family: 'Garamond','serif'; line-height: normal; margin: 0in 0in 0pt 0.25in; text-indent: 0.5in;">Within the mean all the classes basically follow the same trend, as well as within the Coefficient of Variance. However, when comparing the NDVI and the coefficient of Variation, they both follow different trends; when mean is down the coefficient of variance is up.

<span style="font-family: 'Garamond','serif'; line-height: normal; margin: 0in 0in 0pt; text-indent: 0.25in;">Determining the start and end for growing seasons is possible by the NDVI time series; when the mean increases and then decreases it indicates the start and end, each year.

<span style="font-family: 'Garamond','serif'; line-height: normal; margin: 0in 0in 0pt 0.5in;">The phenology would be different if there were no humans in the area and there would be more croplands and forest.

<span style="font-family: 'Garamond','serif'; margin: 0in 0in 10pt 0.5in;">Based on the classes who are most dominant, for the most part follow the same pattern and length. However, class41has a higher mean than the rest and 51 has the lowest. I would of thought class 41, residential rangeland, would have a lower mean considering its population density is usually high and that class 51, populated forest, would have a higher mean than a low one considering it is mostly inhabited by wildlife.
