NR 658 Introduction to GIS Lab Section 6 Lab #5: Spatial Data Chapter Summary: Spatial data is an essential part to any GIS and the ability to edit and manipulate it is easy and a fundamental skill. This chapter taught us where to readily obtain spatial data, how to extract it, unzip it, and import it into our own GIS map. We also learned about metadata and the job it does to describe and help understand its related spatial data. To do this we used Granit, a website filled with GIS spatial data relating to a wide range of topics from wetland inventory to land use maps. This lab was extremely important for our future in the GIS lab because Granit will be used a lot to gather data, and it is even used in the upcoming lab practical. Techniques learned: 1. Convert 2d map to globe projection (pg. 149) 2. Opening and examining metadata files (5-1) 3. Exporting shapefiles (5-3) 4. Downloading maps from Granit (5-3) 5. Exporting Granit maps to ArchGis (5-3) Real World Applications: A theoretical example of this chapter's information would be using Granit website data to identify important bodies of water for conservation. To start I would download the Dover west quad and any data associated with water connectivity in the west dover or Durham area. From there I could add layers of data with roads, soil type, water feature type, and other factors to form a plan of conservation for bodies of water in the Durham area. The map would look similar to figure 1 in the way it shows land use types and water features. Granit data is a very important place to gather data for many different types of conservation efforts in New Hampshire. Difficulty Encountered and Solutions: Although Granit was a pretty simple website I did get confused by the data navigation tool but was able to fix this when I went into the data portal. I was also not able to find the files downloaded from Granit in ArchGis, but I just had to refresh my files and they showed up.
Assignment 5-3: For this assignment I was tasked with extracting a single cell image of a USGS map of a 2015 1-foot ornithology, seen in figure 1 , using the snippet to create a map with all important elements. I chose this specific location in Holderness NH because of the close proximity to squam lake, a beautiful area of which I have spent much time. Figure 1
