Module 4: Geo-referencing & Data Quality

This week I learned what a hectares is, and I learned about queries, buffers, and overlays. Starting with the buffers on this map, I had no idea what exactly was the point of making all the buffers for the roads and water. Halfway through it started to come together, then I understood what was the point, its like pasting then cutting, and doing over while keeping the important information intact like the fields. I am familiarizing my self more every time I make a mistake and have to retrace my steps. My biggest mistake that took hours attempting to find was that the field where the inside road buffers and inside water buffers are in the buffer union's attribute table was showing null. I found out I did not do the field calculator correctly. This was the most challenging lab so far, as I am still a bit confused but I will not give up.

This week I learned the basics of Adobe Illustrator. It was challenging to be able to learn what tools are available and what they do, there are so many. I did get my basics down, I learned how to use the layers feature, the alignment tool, the transparency tool, and the pathfinder tool just to name a few. A problem I ran into was being able to add the halo effect to the text. After researching, I ended up finding a way which was by selecting the text, go under text, then create outlines. I had to mess with the stroke weight and the Align Stoke feature. The Align stroke feature moves the frame within the letter, the default setting had the frame aligned to the center which would make the stroke (halo) overlap the letter and did not look like it was not meant to be. So, I aligned the stroke to the outside and voila!   I am excited that I we are starting to use adobe; I already see the potential of this application.

About me

    Hello there my name is Efren Lopez, I am 28 years young. I have a beautiful wife and three kids. I love to travel to National landmarks with my family. My favorite trip has been to the Grand Canyon and during that visit we also checked out, Meteor Crater and the Hoover Dam. Taking trips to these landmarks motivated me to one day be a part of the team who work to protect and maintain the landmarks. During these trips I handled so many maps that I could have became a tour guide. That when I found out I like maps, and historical land marks. I want to be able to help protect lands and wildlife, and with the help of GIS I can open the door to many more opportunities. This is the reason I joined to help me land a job in the local government at the parks and natural resources department. I have to start small, I want to work for the National Park Service. I hope to learn the basics and proper techniques of GIS upon my completion. I recently graduated with my Associates of Arts and got ac

Well Designed Map Synopsis This map is the ideal map for me, it covers mostly what a map should have. The color combination is ok considering there is 16 different races covered, I would personally choose a different color combination. The boarders of each state is emphasized, as well as the location of Alaska and Hawaii are logically placed to their relative location to the United States. The title is missing, and the boarders are as well, the scale can be larger. Overall, the message is clear what this map is portraying a few tweaks here and there and it should be perfect. Poor Designed Map Synopsis  This map is poorly designed, it chosen color pattern does not go well with each other, there is not enough contrast. The title and subtitles are all disproportionate and use different fonts which makes it difficult to understand the map, also there is no scale, no legend, and no north arrow which also adds to the burden. Overall, it is a very confusing map
