Chapter 2 - Whirlwind Tour
This chapter introduces you to the full range of GeoMedia capabilities.

Chapter 3 - Workspaces
Workspaces are the overall "control" file for each of your GM projects. They will allow you to "get back" to exactly where you were. Remember to create a special directory on YOUR Z drive for them.  This chapter tells you how to set up default projection and coordinate info for your workspace.

Chapter 4 - Warehouses
This is an intro chapter on warehouses (the places where GM holds its data). More details are in Chapter 6 and 36. Key info on the coordinate system file and "ini" files are here. As in workspaces, be sure that you have any warehouses that you will be writing to on your Z drive.

Chapter 5 - Overview of warehouse connections - accessing warehouse data
This chapter details the care and feeding of connections. Connections are the linkages between the GM warehouse and your current work.

Chapter 6 - (this chapter is not yet complete)

Chapter 7 - Using spatial filters
Spatial filters allow you to restrict the amount of data that "flows" from the warehouse to your current project. Effective use of a filter can dramatically speed up your work as you don't have to munge so much data. But be alert to the consequences of the overlaps VERSUS inside operation of the filter!

Chapter 8 Map windows and how they work
This chapter provides key info on how to create map displays and manipulate them.

Chapter 9 The data window and attribute data
The Data window is a spreadsheet like display of the attribute data associated with map units. This chapter shows you how to use the data window and deal with attribute data.

Chapter 10 Customizing the user interface
This chapter provides details on how to set up various configurable aspects of GM so that ti works the "way you work." There are details on setting up the measurements - they can be in a wide range of units - as well as setting up dialogue defaults, the nature of layout windows and lots of other keen stuff.

Chapter 11 Legends - controlling how features are displayed
Legends in GM are used to define all aspects of the display properties of features. In this chapter you can see how to define the scales at which features turn "on and off" and other setting that determine if a feature is locatable etc.

Chapter 12 The Legends - controlling styles
This chapter continues the discussion on legends - providing details on how to set the styles that are associated with the features, fonts, line and area fills etc. are discussed here.  This chapter also covers the use of cartographic symbols, how to access them and, if desired, create them.

Chapter 13 Reusing legends and styles
Once you've gone to lots of trouble to create a map - just the way you want it - how do you use it again? That's what this chapter is about. IN GM you can "reuse" legends and styles to create new maps - but with similar cartographic characteristics.

Chapter 14 Images
This chapter shows you how to add aerial photographs, satellite images, scanned graphics and other similar image data to your GM project.

Chapter 15 - Selecting features
This chapter shows you how to idnetify and choose ("select") specific features based on their location or attributes. Once selected a group of features is a select set and can be manipulated in a variety of ways.

Chapter 16 - Attribute data and dynamic queries
This chapter deals strictly with attribute queries, including the ways in which you can query the attribute elements of a warehouse to
identify the various spatial entities that have the attributes you desire. The following chapter explores spatial queries. An example of a
spatial query is "Display all parcels within 1 mile of the new school".

Chapter 17 - Spatial queries
An essential capability of any GIS or desktop mapping system is the ability to perform spatial queries. Spatial queries are questions such
as "Identify all oil wells in the county," "Find all streets above the water line," "Show all streets that end at the city limits," and "Where
are the valves within 20 feet of the pipeline."  This section presents the spatial query capabilities of GeoMedia

Chapter 18 - under construction

Chapter 19 - under construction

Chapter 20 - Buffer zones
Buffering is the process of creating a new area feature or features (buffer zones) that encompass an area around a point, line, or other
area feature within a specific distance or distances. Buffering may be the most common spatial operation performed in a GIS or desktop
mapping system. GeoMedia has a number of innovative buffering techniques and features, which are covered in this section.

Chapter 21 - under construction

Chapter 22 - Creating themaic displays
Thematic display is a wonderful tool for producing clear, straightforward visual presentation of nongraphic data as entities with a spatial
dimension. Using the data structures that define the relationship of spatial and nonspatial data in the relational database, thematic
display literally translates attribute data, for viewing purposes, into a spatial display. Attribute data are displayed as spatial data using
the linkage between geometries and attributes stored in the data warehouse.

A thematic display is just what the name suggests. It is a graphic representation of geographic features, the display, based on
nongraphic attributes, the theme. Thematic display symbolizes the attribute values of spatial features through the use of color or
patterns. The ability to graphically display nongraphic data provides you with a powerful tool for visualizing the spatial relationships
among the attribute values of a feature class or a query.

Chapter 28 - Geocoding and address matching
Geocoding is associating a geographic location to coordinates while address matching is doing the same - but for a street address. This chapter shows you how to take a text file with (say) lat/lon or UTM coordinates and convert it to a mappable feature class. Similarly it shows you how to convert a list of addresses to their proper coordinates.
