Read Longitude by Dava Sobel for an excellent history of the development of an accurate clock that could be used at sea. It's truly fascinating both from the engineering perspective as well as the personalities involved. And it clarifies that, prior to this development, navigation at sea (at least in terms of longitude position) could best be characterized as a wild ass guess.
Edit: somehow wrote LATitude when I meant LONGitude! Duh!
This is the textbook we're working on in my intro to computer sci class:
>I'm currently reading A Short History of Reconstruction by Eric Foner to work on actively learn more about an era I was taught almost nothing about in school and how the attitudes of reconstruction still are present in our modern society
This was actually the topic of my capstone sociology class. There we read American Apartheid by Massey and Denton. Despite it being an academic text, its actually quite accessible, and it paints a vast picture of how segregation bled into American life from the Civil War to today in many different ways that are rarely -- if ever -- discussed in our schools (e.g. migrations of black southerners to northern states after factories hired them as strike breakers, how the northern states were actually worse w/r/t segregation than the south).
Hey, this is the book that we used in my Python for GIS class and it and my teacher taught me a lot with it. A year after the class, I'm 80% done rereading it, and it's very helpful. works in conjunction with ArcGIS 10.1, and I suggest you use PyScripter, a sweet Python code handler.

It covers a lot of the basics and introduces you to lots of problems you can solve with Python in GIS. It also comes with a CD complete with several exercises for each chapter in the textbook. some chapters are a bit dry, or you think, "oh my god this would be easier to do manually" but it's good at reminding you that with huge datasets, scripting is the way to go.
Do you have to be a student to apply for this??
I graduated in 2013 with a degree in Applied Math & Environmental Hydrology. I have 5 years of experience in GIS Environmental Analysis. I've interned with non-profits, the USGS, and a prestigious Washington DC Environmental Think Tank. I have authorship one peer reviewed report & and will get another in the next year or so.
My biggest weakness is my low college GPA (which is why I focused on internships and research). I also don't know python coding very well but I recently read Python Scripting for ArcGIS cover-to-cover and have been practicing as best I can.
I can't get a job anywhere, I've had to move back home and all I do is job hunt online for environmental GIS jobs. Maybe I'm just unlucky at the bottom end of the bell curve, but ~~the job market~~ hiring culture and expectations is that miserable out there.
I just keep telling myself the Winston Churchill quote "If you're going through hell... keep going."
Yes actually. Even non-slaveholding whites participated in upholding the slave state directly as part of slave patrols.
Ah, you want to Lie with Maps, gotcha. Now you have the link to the book.
There are a lot of people in California since they are the largest populous state, which has around 40 million right now, so it's not surprising that 6 million people voted for the former pres but that large number is still not the majority of the state.
Away from land, people got lost a lot. For a long time we knew latitude using the stars, but longitude was a problem until the 18th century when the chronometer was invented.
This is a great book that probably answers your question in more detail:

>Anyone alive in the eighteenth century would have known that "the longitude problem" was the thorniest scientific dilemma of the day-and had been for centuries. Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives and the increasing fortunes of nations hung on a resolution. One man, John Harrison, in complete opposition to the scientific community, dared to imagine a mechanical solution-a clock that would keep precise time at sea, something no clock had ever been able to do on land.
Longitude is the dramatic human story of an epic scientific quest and of Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clockmaking, and opens a new window on our world.
No problem!
this was the book that I learned from when I was in school and it was very helpful. They have a new edition too I think and one that is specific for ArcPro if you're using that. You can get a license for pretty cheap for a year to keep up with it too which I did when I was in between jobs.
I've also used Code Academy for just keeping up with basics too that are not specific to GIS, but not as useful for model and tool development.
Best of luck to you! Feel free to hit me up if you ever need someone to talk to about your job hunt.
There’s a new version for pro but this book really helped me from step 1 to creating tools
Python Scripting for ArcGIS (Python Scripting, 1) https://www.amazon.com/dp/1589483715/ref=cm_sw_r_awdo_Z8BGDDM5S4KRA7SVZF9N
I didn't particularly like the writing in this one. Too much trying to turn a clever phrase and was poetic, while being so meta as to not be specific about the who ('el presidente' - Well, which one?; the Allan Dulles - ok, sure, but the relationship between Allan and his brother John Foster Dulles, the CIA, the State Department - it's not presented sufficiently clearly here.
If you want a very readable, detailed, well-sourced look at the UFC & CIA's nefarious activities in Guatemala, the touchstone book is Schlesinger, et al's "Bitter Fruit: The Story of the American Coup in Guatemala"
https://www.amazon.com/Bitter-Fruit-American-Guatemala-Expanded/dp/067401930X
Here’s a great book about the mechanical clock revolutionized ocean navigation:

Longitude By Dava Sobel doesn't cover the whole history of watches, but provides a fascinating and entertaining telling of how and why we have marine chronometers.
Dava Sobel’s book Latitude is an excellent account of this event. I highly recommend it and have gifted it to quite a few people.

> but calling it a caste system is a huge misuse of the word.
Turns out, if you live in a system that determines you are worth less because of the circumstances of your birth-- like skin color-- you, in fact, live in a caste system by definition..
SQL, Python, CAD, Model Builder! If you’re not already using some of these they are great skills to have on your resume! Python Scripting for ArcGIS ProPython Scripting for ArcGIS Pro is a great book if you’re using ESRI products. And I’ve heard good things about the free online book “Automate the Boring Stuff.”
"for simplicity sake" sounds like you've got a pre-decided point you are trying to make, and chose the visualization that supports that.
Yes and no. Finding what way is north, super easy, people have been doing it for thousands of years. Finding latitude (how far north or south you are) , also very easy and based on how far above the horizon the north star is. Finding latitude is the hard part that requires those things I mentioned.
Here is a book about the history of celestial navigation: https://www.amazon.com/dp/080271529X/ref=cm_sw_r_cp_apa_i_gYc-FbZZ2Q2CF
The book about this is titled "Moby Duck".

Read Moby Duck if you're interested in the details along with all sorts of other interesting information.
There is a good book and BBC series about Harrison and the troubles he went through making the marine chronometer.
Former comp sci major turned GIS, I took a Python class and then took a GIS programming class. While it was an advantage for me to already know some keywords from the regular Python class, the GIS one and the textbook(s) meant specifically for it were easier and condensed down just for esri related processes.
TL:DR; You’re not going to learn how to do GIS related programming using a regular Python book. Please get a GIS Python related book like this one:
Python Scripting for ArcGIS (Python Scripting (3)) https://www.amazon.com/dp/1589483715/ref=cm_sw_r_cp_api_i_ZfNKFbPSRNT6C
Man muss einfach die Grenzwerte für die Farbübergänge und den Zeitraum geschickt wählen. Gibt sogar Bücher über sowas: https://www.amazon.de/How-Maps-Third-Mark-Monmonier/dp/022643592X/?tag=dsble-21
Und falls es nicht offensichtlich war: das ist ein Spaßpost über Scheinkorrelationen.
There is a newer version of this text book the op might want to know about here: https://www.amazon.com/dp/1589484991/ref=cm_sw_r_cp_awdb_btf_t1_j6SHFbHEE4P2E
That one is great but I think the op might even want the more advanced text book that goes with it here:
https://www.amazon.com/dp/1589486188/ref=cm_sw_r_cp_awdb_btf_t1_B-SHFbE0J3Q1X
I can't recommend either book enough.
I suggest checking out
It was a very useful starting point for me. It will cover all of the basics, plus how to set up your IDE.
I use Pycharm for all my development, but you can use whatever IDE you feel comfortable with.
All the ESRI sites have examples of scripting at the bottom of each tool's page. A quick Google search of a tool plus Arcpy should give you what you are looking for.
Paul Zandbergen has a series of books on python and GIS
A book about how modern navigation was made possible through solving a seemingly impossible problem namely determining the longitude. At the time the solution was thought to be astronomy and the scientific community ignored the simple solution through watchmaking developed by a single man. A nice David vs. Goliath story about a guy fighting to be recognised for a simple mechanical solution to a problem thought to be impossible.
Just a couple: https://lawreview.law.ucdavis.edu/issues/31/2/Articles/DavisVol31No2_Bogus.pdf Here's a book that goes into more detail about slave patrols that are the "militias" that the second amendment talks about https://www.amazon.com/Slave-Patrols-Violence-Carolinas-Historical/dp/0674012348/ Of course, second amendment supporters have tried (and somewhat successfully) distanced themselves from the grim origins of the amendment, claiming that it's for people to rise up against an oppressive government, but does anyone really think that a bunch of pistols, rifles, and even automatic weapons are any match whatsoever for the modern military's huge cache of tanks, missiles, air and sea support, nuclear weapons, unmanned drones, etc?
