Module 6: Isarithmic Mapping

Module 6: Isarithmic Mapping

In this lab, we learned about and used both continuous tone symbology and hypsometric tinting to categorize precipitation data for Washington state. These two methods provide different interpretations of the same data and can be used in a variety of applications. The data was first presented in continuous-tone symbology (first image), then in hypsometric tint (second image) with contour lines. 
While continuous tone symbology provided insight into the precipitation data, hypsometric tint, especially with contour lines, worked much better. Continuous tone has many potential uses. Any data that has gradients would fit this well. For example, elevation data with no set boundaries would be best portrayed by a continuous tone, as it is a gradient. Another example could be the radius of effect for factors such as noise or light pollution, as these are also gradients. 
Hypsometric tint is best used when there are solid lines dividing factors. For example, if you are measuring the number of schools within 100 feet, 200 feet, and 500 feet of sea level, hypsometric tint would be best as it would have solid dividing lines between the three variables. Another example could be something like “number of hikers per 1,000 feet of elevation gain.” This would be hypsometric tint as it would be solid values set every 1,000 feet. 
The second map, the final for this project, uses hypsometric tint, contour lines, and hillshading to show the precipitation data in the most presentable way. It was created using the analytical model REISM (Parameter-elevation Regressions on Independent Slopes Model). This model uses data such as elevation models (DEM) or our 30-year precipitation average to estimate the averages displayed. This was then categorized into 10 classes, and topographical shading was added. A hypsometric tinting scheme derived from precipitation data was applied to the map. Finally, a hillshade effect was applied to add depth to the image.


(Sorry if the layout is odd, I have had this post destroy itself 4 *8-12 times when I move the images, where the undo button stops working, and the post becomes unusable, and I had to partly start over)

About Me - GIS 4006

  About Me Hello everyone, my name is Nick Wagner. I am an undergraduate student pursuing a degree in Natural Science. I am currently working towards a certificate in Geographic Information Systems with the hope of expanding my skills in GIS and the potential future opportunities to work in this field.  I am also a scholar of UWF’s honors program. I have spent the last few summers of 2023 and 24 working at Philmont Scout Ranch in New Mexico. I have worked as both a backcountry PC and a Ranger in Philmont. I also had the opportunity to complete a study abroad in the Galapagos Islands and an internship with the Tarpon Springs Aquarium over the last two summers.  Last winter, I was able to spend 5 days hiking the Grand Canyon with my mother and brother. This was an amazing experience, and I used this as inspiration for my first assignment of the semester, a GIS story map you can view here - My orientation story map for GIS 4006 - https://arcg.is/081u1X I aspire to work in th...

M2 Lab: Typography

Image
Module 2 Lab: Typography For this week's module, we practiced using the label tool in ArcGIS to create good typography in a map layout. We learned the specifics of label design, including font type, size, orientation, and placement.  I took the given design and customized three aspects.  First, I re-did almost all the colors on the map to provide better contrast in the image.  Second, I re-did all the font/text sizing to provide better balance in the map.  Third, after selecting the required cities, I went in and picked the most prominent icons to represent them against the background.  I used a few tools to create this map, the primary of these was the label tool. After importing the map, adjusting the color, and creating the labels, I spent most of the time designing the text to complement the map.
