Getting to know ArcGIS: Tutorial

Although we went through this tutorial very fast, i found it extremely useful while completing the midterm. The first two chapters gave an introduction to GIS thinking as well as an introduction to the software ArcGIS.

Part 2 of the book introduced the key components when working with maps and data within the software. It displayed how to show map data and how to navigate through the sidebar. It shows how to turn layers on and off in order to express different traits. It also shows you what the attribute table is and how it shows you all the information on the map for each layer. It also shows you how to select features within the attribute and that in return these attributes will be highlighted on the map. Chapter 4 shows you how to add data to maps and how to work within each map layer that you create. It also shows you how to use the layout window and how to move the data frame to create titles and legends. In chapter 5 we see how to create a map on the web and how to merge online and local layers already within ArcGIS.

Part 3 looks at displaying data and presenting it in a professional manner. Chapter 6 looked at working with coordinate systems by looking at a series of USstate shp. files. Then it explored the importance of map projections and how to use the Arctool box to help define projections that you may use within the maps you create. The purpose of chapter 7 is to learn information about symbology. You learn how to customize symbols in relation to your maps purpose and you learn how to use the properties tab in ArcGIS to change the characteristics of your symbols. Chapter 8 dives in the how to classify features by standard methods; manual, equal interval, defined interval, quantile, natural breaks, geometrical intervals and standard deviation. I thought this section was really great because i hadn’t learn all of these types form the reading (just a selection few). Chapter 9 talks about how to create graphic labels on your map incase you want writing or drawings on your map. Chapter 10 then pulls part 3 together by talking about how to map the map presentation ready. It reveals how to create titles, additional elements and writing.

Part 4 chapter 11 explains how to create and alter data by initially making a new geodatabase file, in ArcCatalog. It has you import a feature class into the geodatabase file. It also talks about how to add domains and different fields. Chapter 12, was very helpful for the midterm because it talked about drawing and creating your own features on ArcGIS. It teaches you how to create a point, line and area from a shape file on ArcCatalog. In chapter 13 we then learn how to delete and change these features that we have created incase we mess up or need to add certain aspects. Chapter 14 looks at geocoding and creating a address locator with the help of the attribute table.

Part 5 talks about how to get information for your attribute table. Chapter 15 teaches you how to use the identify button to look at the information of your created features. It also talks about using hyperlinks to connect to information that can’t be added to the attribute table. Chapter 16 is useful for learning about why you might want to join or compare spatial data to tabular data and talked about other map tips.

Part 6 is focused on analyzing feature relationships and ends the tutorial. Chapter 17 talks about performing location queries and how to use the select by attribute tool to help with various tasks revolving this idea. It teaches you that you can always change a selected attribute it need be. Chapter 18 talks about finalizing data by clipping layers and exporting maps or data. Chapter 19 talks about buffering features which was also useful when completing the midterm. it also talks about creating graphs which can be very useful when trying to display the goal or purpose of your final map. Chapter 20 ends the tutorial with how to turn your vector layers into raster data and that you must have the same cell size, classification and extent in order for it to convert. Over all the tutorial was a lot of information to absorb, but i really learned from applying some of these concepts to the midterm.

Schuurman chapters 4 and 5

Chapter 4 talks about how GIS is frequently used to store data and provides us the ability to analysis our data more closely. It goes into detail about set theory, map algebra and overaly analysis mentioning buffers, queries and many of the difficulties we face. My favorite part of the chapter is when it talks about the power of the eye. The look at a TB case study to find 5 concentration clusters of the disease. Through small data reductions the visualization was even easier for defining the data. Chapter 5 talked about how GIS research and training. It touched on systems vs. science once more and mentioned that research in growing in the area of GISci.



Schuurman Chapters 2 and 3

Mind the Gap:

-Many people didn’t have access at first (such as Human Geographers) started being used for NGOs. Human Geographers don’t like simplicity of points, lines and areas (vector data).

-Epistemology method used to study the world (using stuff to understand efficiency)

-Ontology method that assumes the world is a certain way (points, lines and areas)

-Data Model use map and put (residential, par commercial and industrial) images with the map of an area —> capture aspect of reality somehow

-Field Model: geographic coordinates with informational attributes. Different from vector data view

-Object data

Chapter 3:

-Data collection and organization: Human collection (census), Metadata ( maps, GIS), Interoperability


— fixed scale

— locations and consistency

— Collection standardized and classification



Geospatial Analysis- A Comprehensive Guide

This academic source will be very useful for the midterm and the final projects. The source gives a quick background on GIS and how applied software can solve problems that occur on your day to day basis. The first section also talks about the intended audience, suggested readings and a list of terminology that is useful for people using GIS software. In the second section, conceptual frameworks for spatial thinking, it talks about gather data. You need to know the sources you are collecting your data from as well as what sources you can legally merge together. It is also important to know how each file type works when collecting the data. It also talks about how some data is free while in other cases it can cost large amounts. 

Delaware GIS Data

The Esri Guide to GIS Analysis: chapter 6 and 7 notes

Chapter 6: Finding what’s nearby—> this lets you find the distance from individual features and from between multiple features within an area. This in return lets you look at events in an area or the features affected by certain influences around the indicated location.

  • measure traveling ranges for different features, knowing what is within this range —> examples: state forester monitor logging, map pinpointing areas where there are fire stations within a certain distance away.
  • Defining your analysis: “define nearness” and measure cost over a surface or a straight line distance over an area or the timing/cost of a summarized area.
  • Use lists, counts or summaries to find the information for your analysis
  • summary statistic—> either a total amount (number of acres of land within a stream buffer) or an amount by category (# of acres of each land cover type  within a stream buffer.
  • Distance or cost rings: Inclusive rings or Distinct bands
  • 3 ways to find whats nearby—>
  • Distance or cost over a network (gives accurate travel cost or distance over a grid) example would be the number of customers within a 5 minute drive of a store.
  • straight-line distance (only gives approximate travel distance- good for selecting features around and area or identifying influences around a feature) examples include buffer around stream or selected parcels within a certain distance of a road or stream.  an example of selecting features within a distance would be selecting customers within a certain distance of a bank (use of attribute table). Example of a distance surface would be the continuous distance from a stream. cost over a surface (can combined multiple layers to value the surface cost of travel- calculating area within a travel range)

Chapter 7: 

Why maps change

Anticipate future conditions (crime patterns, trending in traffic flow)

Placebo effect

Know types of change:

Measure time

Track movement (show patterns )

Time (data not always static) data in attributes
