This tree canopy study was conducted on several different neighborhoods within the area of New Circle road in Lexington, Kentucky.
The neighborhoods involved were:
The neighborhood with the most tree canopy per acre was Ashland Park, while the lowest counted tree canopy per acre was in the MLK Neighborhood. The tallest tree was located in the Ashland Neighborhood, a spruce or tulip poplar measuring, with lidar technology, at 114 feet tall.
This course used ArcGIS’ ArcMap as its primary map-making software. Our initial analysis of neighborhoods inside New Circle Road in Lexington Kentucky.
Lab 1. We created simple base maps of our neighborhood associations and measured the area of our neighborhood in different coordinate reference systems (CRS). We found that the Kentucky single-zone SPCS NAD 83 (EPSG: 3089) was the proper CRS for our study area.
Lab 2.We used ArcGIS Raster calculator to create a Normalized Difference Vegetative Index (NDVI) using red and near-infrared bands found in the National Agricultural Imagery Program (NAIP). Using 2014 & 2016 imagery, we estimated tree canopy in each neighborhood based on vegetation density and compare it to the 2013 tree canopy study (sources below).
Lab 3. We took to the field, using the smartphone application Avenza Maps to map POIs, or points of interests, completely subjective to the perspective of ourselves. We also pinpointed locations where our NDVI analyses did not register a tree, either completely or partly. We then mapped these POIs and NDVI-missed trees and posted our maps to our individual websites at: sweb.uky.edu/~username/nre355.
Lab 4.We made an analysis and map using lidar elevation data and the NDVI vegetation density layer from Lab 4 to determine the height of all trees in our neighborhoods. We assumed that areas high vertical relief and vegetation density where trees. We then took to the field once more to find these predicted high trees and take pictures. These GPS points of tallest trees, their photos, and new canopy cover from picked NDVI were then mapped and added once again to our individual websites.
Lab 5. We individually took the most pertinent data, tallest trees, and true canopy cover from Lab 4, POIs from Lab 3, zipped, or compressed, it and recreated it on an interactive map-making website CARTO maps, republishing this new map as the final addition to our webpages.
Group project. We created this web page by assembling into teams that write the content, design the page in HTML, edit images, and make new maps as necessaery.
