Designer provides functions to create, modify, and visualize all the components of a Schematics project. It greatly reduces the learning curve of defining and customizing specific project parameters and allows you to quickly customize and tailor an existing configuration to a new set of requirements. Designer also allows the user to see, manipulate, and edit diagrams that have been created with a project definition without having to be inside the ArcGIS environment.
When a schematic project is loaded in Designer, two different working modes are available: run mode and design mode. Design mode must be used to build and modify project parameters. Run mode allows you to open, view, and modify schematic diagrams independent of an ArcMap session.
Working in Design mode allows you to create and modify any project component's parameters (diagram type, element type, and so forth). When components are created, a new entry corresponding to the newly created component is automatically created in the table of contents.
Note that, by defaults if you launch Designer from the Edit Project menu that displays when you right-click a schematic dataset entry from ArcCatalog, Designer loads the associated schematic project parameters in memory and opens directly in Design mode.

What's new in Schematics Designer 9.2
Schematics Designer 9.1 was a new major version in which important new capabilities were added to allow managing schematic datasets. In this new version, improvements have been made to make your diagram types creation easier and to offer you the possibility to automatically enable the control of your schematic project parameters while you save them. Another change concerns the possibility to manage schematic layouts and specify their related property values per diagram type. Moreover, as new predefined builders and rules are now provided with Schematics 9.2, you will be able to create and specify new diagram types that will use these new builders and rules within Designer.
Making easier your schematic project conception
New with Schematics Designer 9.2 is the Diagram Type Assistant that guides you in your new diagram types creation and parameters specification. The Diagram Type Assistant automatically launches the first time you edit the schematic project related to a newly created schematic dataset. When you edit a schematic project that already contains schematic diagram type definitions, the Diagram Type Assistant should not automatically open but if needed, you can launch it by right clicking the Diagram Types entry in the Designer tree and pointing to Diagram Type Assistant.

Forgetting to associate your newly created element type with a diagram type, forgetting to specify the origin and extremity nodes for a newly created link element type, etc., are very common oversights while you are customizing your schematic project parameters. With Schematics Designer 9.2, you can now enable the automatic checking of your schematic project parameters while you ask for saving your schematic project. In this case, the Please verify dialog box opens with different levels of warnings that invite you to check some particular points.

Managing schematic layout algorithms and their parameters per diagram type
Until now, if you wanted to specify your own default parameter values for your schematic layout algorithms, you needed to implement a custom component and initialize that component during your schematic project opening. Schematics Designer 9.2 has been extended to support the specification of the schematic layout algorithms' parameters. This customization can be done through the new Layout Task tab, which is now available when any diagram type entry is selected in your Designer tree.
You can also specify which schematic layout algorithms you want to be available or not from the Layout Task drop-down list of the Schematic Editor toolbar in ArcMap and order the schematic layout algorithm entries in this list; this customization can be done diagram type per diagram type.

Tasks you can perform with ArcMap GPS Support
You can perform the following tasks with ArcMap GPS Support.
Show the location on the screen
You can connect a GPS receiver to a communication port on a computer running ArcMap and see the current location on the map display (see Connecting to a GPS device). You can also open the GPS Position window, which shows updated information in real time.
Digitize features
By setting up a log file, you can create a new feature class in which to store GPS locations. Once the log is defined, you can use the Stamp Current Position to Log button on the GPS toolbar to record individual points. If you'd rather automatically record locations to the log, set up the filter options on the Log Setup dialog box and click the Start Streaming to Log button on the GPS toolbar.
Snap positions to features
Consider the following scenario:
You want to have the current location snapped to the features in a feature class. In this example, you are streaming features to a log file as you drive down a road, and you want the locations to coincide with the street centerlines. You set up the connection and position display information. You then use the Snapping tab of the Display Options dialog box to choose the Roads layer (which contains street centerlines) from a list of features on a map. Next, you specify a snapping tolerance. All positions within the specified tolerance will now be snapped to the features in the Roads layer. Learn more about snapping to existing features
Replay collected information later
You can use the Simulate a GPS connection option to review data that was collected earlier and saved to a log. First, set up the simulation by choosing the log you want and set a display interval. Then open the connection to display the locations from the log on the map. You can use any point or line feature class for the simulation data.

An overview of ArcMap GPS Support
ArcMap GPS Support takes as input a feed from a GPS receiver and displays the current location on the screen. You can also store locations from the GPS receiver in a log for archival or real-time digitizing purposes (see Writing GPS locations to a log). You can answer the question “Where am I?” by accessing ArcMap GPS Support through the GPS toolbar in ArcMap (see Adding the GPS toolbar) or by writing a custom application using ArcObjects.
The location is displayed as a user-defined marker symbol. You can have the angle of the marker symbol reflect the direction of motion (bearing), the size based upon the current speed of travel, and the color based upon the altitude. Previous locations can be displayed as a trail of markers or as a line that you can also customize. The trail of previous positions can reflect changes in bearing, speed, and altitude. See Changing the display options for more information.
You can keep the location visible on the screen by panning as needed or have the display pan automatically (see Keeping the current location in the view). For applications like in-car navigation and routing systems, you can snap the location to specified features, such as a street centerline. You can store locations to a log file either in streaming mode (at a specified rate or distance apart) or one at a time. When a log file is specified, you have the option of choosing which columns are added to the output feature class.

An overview of GIS services
You connect to a server by double-clicking one of the three Add Server entries under the GIS Servers folder. (If the GIS Servers folder does not appear in your ArcCatalog tree, click Options in the Tool menu, click the General tab, then enable GIS Services in the list of top level entries.)
The GIS Servers folder also contains an out-of-the-box connection to Geography Network Services hosted by ESRI. This is a connection to an ArcIMS Server residing at ESRI that contains many useful and interesting services, and you should take the opportunity to explore this server when possible. Simply double-click the connection and view the services in the Contents pane of ArcCatalog, as illustrated below. ESRI may add more out-of-the-box connections in the future.

Convey geographic information
Fundamental GIS concepts are closely linked to maps and their contents. In fact, map concepts form the basis for understanding GIS more fully. This topic explores some fundamental map concepts and describes how they are applied and used within GIS.
A map is a collection of map elements laid out and organized on a page. Common map elements include the map frame with map layers, a scale bar, north arrow, title, descriptive text, and a symbol legend.
The primary map element is the map frame, and it provides the principal display of geographic information. Within the map frame, geographical entities are presented as a series of map layers that cover a given map extent—for example, map layers such as roads, rivers, place names, buildings, political boundaries, surface elevation, and satellite imagery.
