Isarithmic mapping

-

In this module, I learned about isarithmic and flow line mapping. We were assigned to create an isarithmic map with contours. The subject of the map is the annual precipitation in inches in Washington state. 

This map was created in ArcGIS Pro. I created this map using data acquired from the USDA and created by PRISM. I adjusted the symbology of the raster file to use precipitation colors (dark blue to dark orange). This map includes 10 manually adjusted breaks, which can be seen in the legend. I then created contour lines that follow the same value breaks. I created a hillshade for this raster using the hillshade tool. I selected the DRA (Dynamic Range Adjustment) tool to adjust the hillshade to the local area. From here the raster layers were ready for a map layout, which I have included below.

GIS Programming- Exploring and Manipulating Data

-
Image
 This week we learned about exploring and manipulating data in ArcGIS Pro with Python scripting. We learned about a variety of tools and methods, such as describe, exist, listing, dictionaries, and cursors. In the assignment, we were given a variety of tasks. First, we were to create a new file geodatabase. Next, we were to list all of the feature classes in another folder. We then copied those feature classes into the new file geodatabase. Using one of the files in the new geodatabase, we used the search cursor to identify the objects that matched specific criteria and printed that information. Finally, we created a dictionary with this information.  I encountered issues with populating the empty dictionary. I was attempting to use the row.getvalue method,  I kept receiving the error that my tuple did contain the attribute. I began my troubleshooting by searching for various methods to update dictionaries. From there I edited small things in my script, such as the input ...

Spatial Data Quality Standards

 This week we learned about the various data quality standards, specifically NMAS and NSSDA. In our exercise, we applied the NSSDA methodology to test the accuracy of two maps in Albuquerque, NM. The two maps are from the city of Albuquerque and StreetMaps USA. I used Minnesota Planning's Positional Accuracy Handbook as a reference(1999).  After downloading the provided data and before starting the analysis, I first created my excel spreadsheet based on the worksheet provided by the Positional Accuracy Handbook (Minnesota Planning, 1999). Next, I created a point feature class and selected my 20 sampling points, referenced in Figure 1. I made sure the points were properly distributed, with each quadrant having less than 20% of the points. They are all located at intersections.  Figure 1. 20 sampling points on the city of Albuquerque's map. I then created two more feature classes for the StreetMaps USA map and the reference points. I made sure that I went in the same order ...

A little bit about me..

Hi there! My name is Emily Talbert and I am currently working on my master's in Historical Archaeology at UWF. I received my bachelor's in Anthropology from the University of South Alabama. This is my second GIS course, the first of which was focused only on archaeology, so I am excited to get a broader understanding of GIS. I am hoping to gain a really solid foundation in GIS that I will be able to apply to my future career in archaeology. I know that GIS is a valuable skill, so I am trying to learn as much as I can! Outside of school, I spend most of my time with my kitten, baking, cooking, hanging out with my friends, and distance running. Here is my story map:  https://arcg.is/TafeO.
