ArcCatalog

• Think of ArcCatalog as a window into your
  database. In ArcCatalog, you can browse,
  organize, distribute, and document your GIS data.
  ArcCatalog resembles the Microsoft Windows
  Explorer but is designed for viewing geographic
  databases, maps, and metadata (data about data).
• To access data from ArcCatalog, you must set up a
  connection to it. After you add connections to
  your geographic data to ArcCatalog, you can
  connect to folders on your computer and also to
  shared folders and databases on a network. The
  collection of connections you set up to
  geographic data is called the Catalog. The
  Catalog Tree gives you access to all the
  Catalog's contents. In the ArcCatalog window
  below, the Catalog Tree is on the left side.
• Inside ArcCatalog, there are three tabs, each of
  which provides a unique way to view the contents
  of a selected item in the Catalog Tree. The
  Contents tab shows you a list of the selected
  item's contents. The Preview tab lets you see the
  data (both geographic and tabular) contained in
  the selected item. The Metadata tab gives you
  access to documentation about the selected item.
• There are different ways to preview geographic
  data. You can create thumbnail images of your
  data to display it graphically, or you can
  display it with large icons, with small icons in
  list view, or in details view which displays
  small icons and the data's properties.
• It is important to keep records of your GIS data
  inventory. You may need information about the
  data's accuracy or how a set of measurements was
  collected. An item's metadata includes this type
  of documentation, along with many properties
  derived from the data automatically. ArcCatalog
  provides metadata editors, in which you can
  create, edit, and view metadata

ArcMap

• ArcMap is the ArcInfo application you use to view
  and edit geographic data and create
  professional-quality maps, graphs, and reports.
• A map is the fundamental component you work with
  in ArcMap. Maps help you visualize geographic
  data by showing you where things are and what
  they look like. You can drag and drop data from
  ArcCatalog directly into ArcMap. When you want to
  work with a map, open ArcCatalog, find the
  desired map, and simply drag it onto the ArcMap
  display area.
• Geographic information is displayed on a map as
  layers, where each layer represents a particular
  type of feature. In ArcMap, the Table of Contents
  lists all the layers shown on the map. By
  default, the Table of Contents is located on the
  left side of the ArcMap application window, but
  you can move it to a different position if you
  like. The order of layers within the Table of
  Contents is important the layers at the top of
  the Table of Contents draw on top of the layers
  below them. Thus, you should put the layers that
  form the background of your map, such as the
  ocean, at the bottom of the Table of Contents

ArcToolbox

• ArcToolbox is the ArcInfo application you use to
  perform advanced GIS analysis tasks and
  sophisticated geographic data processing jobs,
  like creating and integrating a variety of data
  formats into usable GIS databases.
• With ArcToolbox, you can convert virtually all
  major spatial data formats. You can generate and
  maintain topology join, clip, and split map
  sheets, and use advanced modeling tools.
• ArcToolbox also supports drag-and-drop (coverage
  or grid) operations from ArcCatalog. ArcToolbox
  contains over 140 tools organized in a searchable
  tree hierarchy, and also provides wizard
  interfaces for complex tasks like data
  conversion, overlay processing, buffer creation,
  projection and map transformation.
• ArcToolbox provides a link to ARC, ARCEDIT, and
  ARCPLOT because it seamlessly accesses their
  functionality through the Open Development
  Environment (ODE).

Copy lab data to local computer

• As C/GTKArcGIS
• These data are mostly our lab data, but we do not
  use all of them. If you are interested in, you
  can do the ones left.
• You will copy other lab data to the same
  directory (C/GTKArcGIS) while you will work on
  the lab.
• Always save your project and data to MyData under
  each Chapter.
• Lab results submission (screen prints via email).
