Map Explorer
displays the elements of your map project, such as the files you've attached as sources, queries you've used and saved, templates for linking drawing objects to data, and so on. Use this view to query in objects from attached drawings and view the data for any object.
Display Manager

- where you manage features stored in data stores (databases, geospatial data files, and raster files), attach drawing files, and change the appearance of features
Map Book

- where you divide a large map into "tiles." Each tile is rendered on a separate page. You can publish map books in various formats, both for printing and for online display.
Survey
- where you bring in and work with survey point data.

Exercise:
Exploring the User Inteface
Lesson 1
Global coordinates system is a method of representing part or all the curved surface of the earth on a flat plane.
Many mapping systems use different coordinate systems. You must be able to assign correct coordinate systems to these drawing to use them in a single environment.
Apply coordinate systems to source drawings.
Before assigning a coordinate system to source drawings, they must be detached or deactivated from an open current drawing.
Apply coordinate system to a single current drawing.

It does not change any of the coordinate values of the objects, but rather defines what system the existing coordinates represents.
When a draw query is performed from a source drawing that has a different coordinate system than the current drawing, the objects are transformed into the current drawing coordinate system. The actual coordinates of the objects are changed. If they are saved back to the source drawing, the transformation is reversed to the original coordinate system.

Lesson 2

Raster
Lesson 3
Raster data – data files that most commonly represent images, such as photographs or other graphics that are attached to the drawing but is not part of a Map drawing. Formats are .bmp, .jpg, .gif, .tif, .sid, .tga, and .png (e.g. aerial photographs, pictures from a digital camera, satellite images, scanned images, old deeds or property plans)
Exercise:
Adding Raster Image
1. If a current drawing is assigned with a coordinate system, the attached drawing to it (even if with different coordinate system) will be transformed to the projection of the current drawing.
2. To convert permanently, after assigning the target coordinate system, attach the drawing to be converted, and then detach the source drawing. Save the current drawing.
Source Drawings

are drawing files that are attached to a current drawing but are not loaded into memory until a request is made through queries.
You can access objects in these source drawing through:
Queries – Tools that retrieve objects from source drawings into the current drawing. The specific sets of objects you need will be shown in the map.
Quick View – Creates a temporary display of all the objects in the drawings, can be performed after attaching or querying.
Save- back – edited queried objects placed in a save set, are locked to prevent other users from editing them until they are saved back to the source drawings.

Detach, Deactivate
Source Drawing
Attach / Detach – attaching/ detaching drawings to the current drawing adds/removes them to the existing drawing set. If you save the current drawing, the detached drawing will not reattach or activate the next time you open the next drawing.
Activate / Deactivate – activate reactivates drawings that have been deactivated. Deactivate (to release lock) is same as detaching but the drawing is not removed from the drawing set; ignored during queries and quick views, when current drawing is saved and reopened, the deactivated drawing will remain but will not activate automatically.
is a request for specific information based on location, object properties, or attribute data to get drawing objects specific to your purpose.
Query
QUERY MODES
Preview Mode – does not create objects in the current drawing but shows the objects as temporary image.
Draw Mode – objects retrieved are copied into the current drawing.
Report Mode – Use to produce a list of objects in source drawings. Information such as the insertion points, start and end points, object data values, and SQL values can be included in the report.
QUERY TYPES
Location Queries
- retrieve objects from source drawings based on location criteria or location conditions on boundaries, buffer distances, existing objects, crossing criteria
Location Conditions
Buffer fence
- retrieves objects within a specific distance of a polyline that you define.
`
Fence
– retrieves objects that cross a polyline (fence) that you define
Polygon
– references a polygon that you draw in the current drawing.
Polyline
– you select an existing closed polyline in the current drawing as the boundary point.
Property Conditions.
Use object properties, such as layer, elevation, and linetype, to retrieve objects from source drawings
Data Conditions
Object Class
– a special classification for data that can be assigned directly to objects in Map 3D

Object Data
– an option for data stored in tables that are internal to the drawing.

Object Properties
– Refers to data stored within all AutoCAD normal and custom objects. When using this data types, it is recommended that you check the box to include all subclasses

Attribute Data
– A special type of data stored within AutoCAD blocks.

Database Link
– An option that searches the Key Field of external database tables with record that are linked to drawing objects.

Creating and Attaching
Object Data
Lesson 8
is an attribute data (simple table containing text and numeric data) that is attached to any object and stored in a drawing file (use: storing topology information).
Object Data
Creating Object Data
Attaching Object Data
Exercise:
Working with Source Drawing
Object data does not provide a method of viewing all records in a table. Therefore, this is edited by editing the values in the fields of a table that is attached to an object.
 
Single edits – use the Properties Palette and the Edit Object Data dialog box as efficient methods
 
Multiple edits – use selection tools or queries to select the objects, then, use the properties Palette to change the value for all objects.
All records are not affected if you edit the values in an individual object data. In the case of modifying a table, all instances of the table are changed. For example, adding a field to one object data table will change the object data table of all objects of same layer.
Tricks &
Pitfalls
If you want to use the same table on a new drawing, just copy an object with that table from the old drawing and paste it on your new drawing.
If you will export an object with the same table name but different fields, one of the tables will be deleted together with the content of the fields.

Importing &
Exporting Data
Lesson 9
Developing a mapping system requires acquisition of data from various agencies and may be of wide range of data formats. You can import and export files from different data formats without altering the geometry and the underlying data linked to the objects.
Data Import – a file with different formats, for example ArcView with 3 file types: SHP, DBF, and SHX, is placed on a layer of Autodesk Map 3D.
Data Export – drawing from Autodesk Map 3D is converted to a target file format.
Import and Export operation maintains the integrity of the original data as closely as possible!
Exercise:
Importing & Exporting Data
Working with
Feature Sources
Lesson 10
Feature Source
is any source of spatial data that has been connected by means of feature data objects. An FDO enables you to connect directly to SDF and raster data and databases that contain spatial data. No import or export is necessary to use the spatial data that resides in the original feature source.
3 Main Types of Feature Sources
File-based Feature Sources
– SHP and SDF for vector information; ECW, MR SID, TIFF, and JPEG for raster; digital elevation model file, such as the DEM.
Database Feature Sources
– ODBC provides a point type of feature source; Oracle Spatial, ArcSDE, SQL Server and MySQL provide a full-vector feature source containing points, lines, and polygons.
OpenGIS Feature Source
– WMS for raster-based feature source that returns images, such as PNG, as data; WFS that returns full-vector feature sources from external sites. These OpenGIS feature sources require a URL to find the server (such as Autodesk MapGuide® Enterprise) that provides WFS and WMS.

Editable feature sources enable attribute and graphic creation, modification and deletion. Other feature sources are either read-only or have no vector-based feature that can be edited. The following feature sources support full edting: ArcSDE, MySQL, ODBC, Oracle Geometries, SDF, SHP, and SQL Server.






You can draw features very quickly and select them, but you cannot edit them until they are temporarily converted into drawing objects by Checking out (For best performance check out only those features you wish to edit). After the drawing was modified, you can check them in by clicking the Check in Button.








You do not have to Check-In or Check-Out if you have enabled Update Edits Automatically or Check-Out Edits Automatically in the Edit menu.









New drawing objects can be converted into features using the New Feature from Geometry Tool in the Create Menu.

Exercise:
Working with Feature Source
Merging Geospatial Features
You can select any number of connected or touching features and merge them into a single feature. Attributes are combined according to the rules established in advance for the merge command.
Splitting Geospatial Features
To split geospatial features into two parts, you can use the split tool. The resulting feature property values are determined by rules you specify in the Split and Merge Rules dialog box.
Splitting and Merging Features
to be demonstrated by Joel
Split (Divide) Rules:
Copy
– duplicates the attribute value for each new feature.
Divide
– divides the attribute value by 2.
Empty
– sets both attribute values to null.
Proportionate
– distributes value based on specified criteria.
Calculation
– sets value based on specified formula.
Merge (Dissolve) Rules:
Concatenation
– combines property values together
Empty
– sets both attribute values to null
First Selected
– the value of the first selected feature
Last Selected
– the value of the last selected feature
Count
– the total number of merged features.
Minimum
– the minimum field value of merged features.
Maximum
– the maximum field value of merged features.
Average
– the average field value of merged features.
Median
– the median field value of merged features.
Sum
– the total of field values of merged features.
Calculation
– the value based on specified formula.

Lesson 12
Filtering Feature Sources
Two Distinct Ways
in Filtering Features:
Attribute Filtering
– an attribute based query in order to filter features that appear in your map is through an attribute data such as properties, object data or link template.
Spatial Filtering
– Filtering data spatially by locating a region on a map in order to crop the data that is displayed in map.
The Create Query dialog box is used to create filter statements that can be a combination of conditions using the available functions. Logical operators, such as AND, OR and NOT can be used to string multiple conditions together.









The Locate on Map enables you to filter features that are within a polygon, rectangle or circle. These polygonal objects can be drawn dynamically or already exist in the map. You can also choose to spatially filter based on touching any part of a circle, fence, point, polygon or rectangle. Again, you can choose to draw these linear features on the map or choose pre-existing objects.










Applying Filter during the Data Connect process increases map performance.
Exercise:

Using Calculated
Properties
Lesson 13
You can extend the number of properties available to you by creating a calculated property for a geospatial feature. Like joins, calculated properties result in extra columns in the data table. You can then use the new property to theme the data or to filter the features.
You can store the resulting calculation as a new property in the Data Table. It will be available whenever you open the map in which you created it. But it is not saved back to the original data store. Calculated properties are gray in the Data Table, because you cannot edit them.

Moving Data Between
DWG Objects and FDO Features
Lesson 14
The New Feature From Geometry tool enables you to use DWG objects as graphics in any vector-based FDO feature source (SDF, SHP, Oracle, SQL Server, MySQL or ArcSDE). Since DWG objects are migrated as geometry, no tabular information, such as block attributes, object data or link template connections will be attached.

Also, since most FDO feature sources support multiple feature types, such as multipolygon and islands, the New Feature From Geometry tool enables you to select multiple objects to act as a single object, prior to prompting you to enter data in the data window.

This New feature tool does not allow bulk selection, so you must objects individually. After selecting one object, you enter its attribute information in Data Table and then select the next object.
