7 Interface Toolbars Drawing Set Map Oracle Spatial Interface Toolbars Cont d Coordinate Geometry Oracle Spatial Advanced Topology Polygon Annotation Classification Anno Template Map Options

8 Demonstration Review the Interface Autodesk Map Working with Projects Section Objectives Project Creation & Uses Project Workspace Working With Attached Drawings

9 Definitions Source Drawing - Any AutoCAD drawing that you want to work with Attached Drawing - A drawing that is attached to a the current project and available to retrieve data from Project Drawing - A visibly empty drawing that contains settings and information for use in performing many Autodesk Map functions Project Functions Work with multiple drawings Query Edit Multiple coordinate systems Thematic maps Project Information An AutoCAD drawing file List of Source Drawings to be Accessed Global Coordinate System User Preferences Predefined Queries Connections to External Databases Link Templates Key View Settings Thematic map definitions

10 Project Concept Attached DWG s Project A QuickView B C Project Creation Start a new drawing Login to Autodesk Map Assign coordinate systems Attach source drawings Attach databases Zoom attached drawings extents Quick view of attached drawings Save your project Project Use Procedure Open a project drawing Login to Autodesk Map Create & execute a query Plot, edit & save back, or saveas new drawing

11 Project Concept Attached DWG s Project A B C Sample Data City of Dublin Parcels Utilities (water, sewer) Attribute Information Demonstration Create a Project Attach water_data sewer_data Create a drive alias (Map_Tutorial) Zoom attached drawings extents Quick view Activate/Deactivate drawings

12 Questions What functions can be performed in a project? How is a project stored? What is the difference between a drawing and a project? How can you tell if a drawing is deactivated? Autodesk Map Querying Data Section Objectives Use of Queries Four Query Types Three Query Modes

13 Definition Query - A set of criteria used to specify what objects or data is to be retrieved into the project Note: Drawing is treated like a database Query Concept Tiled Query Project Source Drawings Functional/ Overlaid Source Drawings Query Project Query Concept Attached DWG s Project

14 Query Concept Attached DWG s Project Query Query Types Method of Interrogation Query Types (criteria) Location Property Data (Object, Attribute Data, Feature Class) SQL (External Data) Query Modes Query Modes Preview (similar to quick view) Draw Report

15 Query Type & Mode Demonstration How to define queries Location (crossing circle) Object data (pipe diameter >= 8 ) Report query Quantity calculations for linear feet of 8 pipes Questions How do you retrieve objects from source drawings? How does Map know which drawings to retrieve from? What are the four query criteria types available in Map?

16 Autodesk Map Advanced Queries Section Objectives Combine Query Types Property Alteration Using the Query Library Compound Queries

17 Demo Compound query on parcel information Drawing Parcel2.dwg Year built (YEARBLT) = 1967 Lot sqft (TOTAL_) >= 8000 Property Alteration Modify AutoCAD objects as they are queried from source drawings Color Layer Line Type Width Add Annotation & Hatching Note: Source drawings are not affected Property Alteration

18 Expressions & Syntax Object Data Value Block Attribute SQL Value Object Property Values.Property Demonstration Property Alteration Query Source Dwg Project Query Object Data Dia = 1 Color = 1 Width = 1 Demonstration Property alteration queries Drawing Parcel2.dwg Query parcel polygons (1) Solid hatch color = green (2) Label owners last name Text ht = 12 Color = red

19 Demonstration Property alteration query Drawing Parcel2.dwg Query parcel polygons Multiple criteria Solid hatch all parcels color = green Attributes owners last name & year built Text ht = 8 Color = red & blue respectively Pedit all polylines w=5, color = grey Saving Queries Two Ways Internal Stored in the project Only accessible within the project External Stored outside the project in a file in the format of AutoLISP statements (editable) Available to other projects Files use the.qry extension Saving Queries External

20 Query Library Tool to Organize Queries Categories Long Desc. Rename Execute Category Name Demonstration Save an internal query Category: Parcel Name: Owner_Built Save an external query name: sample.qry Active drawings Location coordinates Alter properties Questions What connectors or operators are available for compound queries? What query mode must be used to perform property alteration? What is the advantage of a saved external query? What are some of the properties that can be altered during a property alteration query?

21 Autodesk Map Thematic Wizard Section Objectives Discuss The Process Of Thematic Mapping Learn to Use The Thematic Workspace Use The New Thematic Map Wizard Create Themes Load & Save Thematic Maps Definitions Thematic Mapping - Dynamically Generating Colors, Fills, Symbols, Line Types, and Text Based on The Data Linked to Objects. A Theme Defines the Symbolization of Specific Features Thematic Map - Can Contain Many Themes and is Saved Within an Autodesk Map Project

22 Thematic Mapping What Can be Thematically Mapped? Queried objects from a set of attached source drawings A topology from a source drawing Themes What is The Criteria? Values by.. Single, Specific, or Range Grouping by.. Equal Interval Quantile Standard Deviation Optimal Themes What Properties Can Be Changed? Object Color Object Linestyle Block Insertion Text Hatch/Fill

23 Thematic Maps Activate thematic workspace Create a map Add themes Thematic Wizard Theme Types Thematic Wizard Sample Process

24 Thematic Wizard Thematic Workspace Map Name Theme Execute Thematic Wizard Loading Maps Loading a Map

25 Brian s Thematic Map Cookbook Start a new project Attach source drawings Zoom attached drawing extents Switch to thematic workspace Add themes Save project Load and create maps Quit project without saving Demonstration Use the Thematic Wizard Create a zoning map Project Project_thmw Drawing Parcels_thmw Questions Where and how can a new theme be defined? What properties can be changed when creating a thematic map? Where are thematic maps stored?

26 Autodesk Map Coordinate Systems Section Objectives Components of a Coordinate System Working with Multiple Coordinate Systems Assigning a Global Coordinate System Mapping Issue World is Round (Spherical, Lat, Long) Maps are Flat (Planar, X, Y)

27 Definitions A datum is a reference used for surveying and mapping of the earth that serves as a basis to compute all horizontal and vertical positions. Horizontal Datums North American Datum of 1927 (NAD27) North American Datum of 1983 (NAD83) Definitions An ellipsoid is a geometric model that approximates the shape of the earth. Ellipsoid Clarke Spheroid 1866 Geodetic Reference System 80 (GRS80) Definitions A datum is the description of the horizontal & vertical locations relative to a specific location An ellipsoid is a geometric model of the earth s shape

28 Definitions A map projection is used to convert real world latitude/longitude coordinates to planar coordinates for mapping purposes Coordinate system consists of a projection, datum, ellipsoid, and local parameters Map Projections Types of Projections

29 Projection Comparison Coordinate Conversion Map Supports Source Drawings in Various Projections A Project Can Only Have a Single Coordinate System Process Assign Project Coordinate System Setup each Source Drawing Coordinate System Assign Global System

30 Example Project SP 83 UTM 11 SP 27 SP 83 UTM 12 Spatial Data Sources SD1 SD2 SD3 SD4 Considerations Assignment You cannot assign coordinate systems to any source drawings are attached and active. The drawings should be detached. The coordinate system then assigned and the drawing reattached. Coordinate system info is stored within the drawing file. Considerations Raster Objects Coordinate system transformations may not work as expected on raster objects.

31 Coordinate Conversion Behind The Scenes Map converts each source drawing to the projects coordinate system On The Fly when a query is executed On a save back the objects are converted back to the coordinate system of the attached source drawing Demonstration Convert Faults Drawing in Lat/Long WGS84 to NAD83 Calif. State Plane Zone III (feet) Open drawing Streets.dwg Set coordinate system to CA83IIIF attach drawing Fault.dwg Assign coordinate system LL84 Questions How can you permanently convert a coordinate system? What spatial properties can be distorted when using a map projection? Why do we use map projections?

32 Autodesk Map Editing Multiple Source Drawings Section Objectives List the steps involved in editing process Use the Save Back feature to save new and edited data to specific drawings Advantages and methods used in a multi-user environment File Locking Open a drawing No other users can open or attach drawing except in a read-only mode Attach a drawing (Map Only) Locks the drawing from being opened by other users by creating a file lock (.dwk dwk) Other Map users can attach, query and edit objects from the same drawing Users cannot edit the same object at the same time!!!

33 File Locking Drawing AutoCAD or Autodesk Map OPEN Autodesk Map OPEN or ATTACH Single User Autodesk Map ATTACH Drawing Autodesk Map ATTACH Multi-User Object Level Locking All queried & new objects added to the save back set are locked in their respective source drawings Object locks are removed once the save back command has been executed Editing Transaction Model Source Drawing Project Save Back Set (SBS) Query Locked Move/add SBS Unlocked Save Back

34 Query Edit Save Objects to Src Dwgs Add to Save Set no Stop Remove Locks From Objects yes Is Object Locked Error yes Object Locked By Another yes More Edits no no Lock Object in Src Dwg yes Stop Add to Save Set More Edits no Editing Operations Two Types Modify queried objects Create new objects Saving Back Two Step Procedure Add objects to the save set Save objects to source drawings

35 Working With the Save Set Adding objects Modified queried objects are added by request New objects must be added by selection Save Back Options Queried Objects to Source Drawings Newly Created Objects Selective Layer (coincident) Area (tiled) None Save Back Options

36 Undo Edits Issues Map functions respect the undo & redo Edits Saved Back to source drawings cannot be undone Other Methods Remove objects from the save set Detach source drawings Quit project or Drawing maintenance Multi-User Environment Administration Setup user accounts rights Force user login & Multi-User Messages

37 Multi-User Messages Demonstration Edit Objects & Save Back to Source Drawings Single drawing edit Drawing \add stuff\edit.dwg Multi drawing edit Project \add stuff\my_project.dwg Questions Can two Autodesk Map users open the same drawing at the same time? Can two Map users that have queried the same object edit it at the same time? What happens when you add an object to the save set?
