Project 4 - Analysis 1

Intro to Tilemill and Leaflet

GIS4930

This week we jumped into learning Tilemill and Leaflet, both free open source software packages.  In Tilemill we learned how to navigate through the program and added layers, modified symbology, and brushed up on my color brewer skills.  All this while utilizing code to do so.  In Leaflet we learned how to reach out and captivate an audience through the power of web mapping.  By scraping some source data, we modified it and made it our own.  In Image 1 you can see the code utilized to identify a point and modify the text that appears on that points popup window.  Here also you can see how a circle was drawn to identify a food oasis area.  Finally in the code you can see the lat/long points utilized to draw a polygon, and the code that made it possible.

Image 2 shows how the coding from Image 1 was displayed on the web map.

Image 2 - Webmap of Pensacola Florida depicting the identifiers build into the code.

Later in the same lab, I was able to add more layers to the webmap and make them intractable.  In Image 3 below you can see discgolf locations found around the Pensacola, Florida.  The dialog box in the upper right shows what layers can be turned on and off with a click of the mouse.

This weeks lab was a great lab!  I will definitely put to use what I learned this week in project I have planned for the future.  What great tools, and for the right price too!
