Deed Drafter output is a Cadastral XML. It contains all the traverse information + additional information like the line type, plan information, spatial reference system and more. Can Deed Drafter be used without a parcel fabric? The answer is yes, for example to check for closure and calculate the area Does it make sense to use Deed Drafter without the parcel fabric? Deed Drafter is one component of the ArcGIS for Land Records Solution. The Solution includes many apps and maps that all use 1 common information model: the Local Government Information Model. If you adhere to the information model and the solution it will make your workflows more efficient, improve your data quality and make it easier to deploy the rich content you maintain.

It looks like you might have 2 separate issues: If you enable the LGIM (Local Government Information Model) a feature linked annotation and a few relationship classes are added. This should not have a major impact on your SDE performance. Please contact technical support if you are having a geodatabase performance issues. Transform parcel tool not responding - please verify it works against the same parcel on a file geodatabase. If it does, this might indicate again a SDE issue. To export a few parcels to an empty fabric you can select the parcels and export to a cadastral XML. I would suggest to contact technical support for this issue as well. ... View more

Hello Rhonda, Could you please provide more information why you have 3 different numbers for the same parcel. Is this a Tax parcel, Lot? Condo unit?. Are you working with the ArcGIS Solution for Land Records and the Local Government Information Model? Thanks, Amir ... View more

Hello Dennis, The lines.type field is identical to the parcel.type field. This can allow you to separate the lines of lots from the lines of subdivisions. In version 10.1 SP1 we set the lines.type field for newly created parcels. Another filed on the lines is called �??Category�?�. This field is used to separate boundary lines from road frontage lines, connection lines etc. It is useful to use Road Frontage lines if you plan on running a LSA adjustment in the future. You can set the Road Frontage lines to remain straight within a specified tolerance. I would not recommend using the Category field for Easements and ROW type. Since easements have an area, I would use a parcel type for this. Those are considered Encumbrances (type=9) and have a field call EncumbranceType and a Domain lrEncumbranceType. We do not distinguish between freeway, highway, local�?� ROWs because they overlap �?? who is superior to who? How do we prevent area from being calculated twice for those overlaps? It can be interesting to know what is the business requirement of separating the ROW types? Is it only for symbology (cartography) and\or other business requirement? Hope this answers your questions, Amir ... View more

Hello Tom, Having the resources to capture the parcel from scratch is a privilege not many counties can afford. If you capture them correctly you should end up with very good data. Here are a few recommendations: Start with a good cadastral framework, in your case good PLSS sections. If you can have a surveyor recapture the section corners any other legal document that ties to the framework will have better accuracy. In some areas you might also need the quarter section corner. Capture all the parcels, including the historic parcels, and make sure to enter the legal start date and the legal end date. Use the Local Government Information Model �?? this will save you time of data modeling, editing map configuration and you can benefit the automated workflows. If you find out that after you capture everything you can for an area you still have holes �?? use the legacy data with low accuracy (6 or 7) and the first join option. Use plans to reference the legal document (subdivision, deed�?�) that created the geometry. You can save it on a shared directory and use the plan source document field to paste the link, making it easier to retrieve later. Use accuracies when entering data on plans. Capture the lots and the ROWs �?? this will maintain connectivity and will allow you to run adjustment (LSA) in the future. There are probably a few more that might be data specific that you will encounter. Start with a pilot area to come up with the best process that includes QA. Amir ... View more

The annotation expression has been modified. Make sure that on the annotation classes tab --> expression, you have: 'Display coded value description' checked off 'Advanced' checked on The Lines Bearing field is set a Number Format of Direction (in degrees, quadrant bearing) Adjust the expression below to display bearing if required, minimal line length for anno, minimal line length for bearing, curve parameters Make sure the SQL Query on the Annotation Classes tab does not filter a parcel type In 10.1 SP1 the line.Type field is set to the Parcel.Type making it possible to distinguish between Tax parcels lines to Lot lines etc. If anno is not displayed - verify the values exist in the line (e.g. sometimes curves were imported without an ArcLength and will only display a radius) As always - feedback is welcome You can try to copy and paste the following expression into the annotation class: '*******Description******** 'This expression only shows dimension only for lines of Category 0 and Category 5 for which the hide field is 0 or Null 'Default: show dimensions as distance for straight lines and radius and arclength for curves.  Hide dimensions if distance is smaller than 5 map unit.

Hello Jake, After enabling the Local Government Information Model, new domains with an 'lr' prefix will be added and the appropriate fields pointed to those domains. Since one of the goals of having the same information model across the US: - Do not change the domains, but if necessary change the domain description - Do not change the fields, but if necessary change the field alias (e.g. parcel Name to 'APN' or 'PIN' etc.) - You can delete domain values that do not apply to your county to minimize the drop down list - You can delete old domains that are not prefixed with 'lr' Map File: The map has been optimized for parcel editing in the US. It is designed for parcel editing and not for map production that usually outputs a map in black and white. Since a map tells a story, like a language, wouldn't it be great if it told a similar story across counties?! - create a new map document and start by dragging and dropping the parcel fabric (that is enabled) to the map - Change symbology and any map definitions as necessary - You cannot re-order the layers: if you think the ordering is wrong, please let us know what you think needs modifying - Layer names can be changed (e.g. change the cadastral framework from PLSS names to metes & bounds names) - The cadastral framework parcels have no fill color and are placed above the tax parcels. I can see  this becoming a problem if you do use a fill color. In general: We would like to create the best editing map for parcels and for customers to be able to directly start work with it. Any feedback is welcome in an effort to improve and perfect this map. Amir Bar-Maor ... View more

Over the last few years, Esri has been focused on thedevelopment of a Parcel Editing solution that leverages the Parcel Fabric datastructure. As such, Iâ??d like to sharewith you some of the benefits weâ??ve identified and heard from users whoâ??vedeployed their editing solutions on top of this underlying data structure. Benefits of Using a Parcel Fabric The parcel fabric is designed for parcel maintenance andprovides the following benefits: 1. Data Integrity â?? thetopological relationships between the parcel, lines and point are persisted asan inherit part of the data. This behavior doesnâ??t exist with simple featuresand topologies. When you edit/interact with simple features in a topology, auser might perform an edit that breaks a rule and you must validate and fix theerror to persist data integrity. When you edit/interact with a parcel fabric,the user does not have to worry about that since the fabric maintains thoserelationships and ensures data integrity. 2. Historical Parcels â??Parcel history, or lineage, is a native feature of the parcel fabric. Any transaction, such as a split or a merge,retires the parent parcel(s). The historic parcels are not deleted but markedhistoric automatically and can be viewed in any time, even with a time enabledlayer. 3. Legal Start/End Dates â??Each parcel has a legal start and legal end date that allows you to track thelegal creation of that parcel. This isin addition to the system start and system end date. 4. Record Measurements(COGO) - Therecordvalues or measurements on a line are never changed, even if the line geometrychanges in the parcel fabric. Records values are used to calculate misclosures,legal area and other processes. Each parcel has its own set of lines. Thisallows 2 lines to be connected to the same start and end points yet havedifferent records measurement. 5. Stacked parcel typesâ?? the fabric support stacked parcels that can connect to the same points. Forexample, a subdivision, lot, and tax parcel all use the same points on thesubdivision boundary. If those points move, all the parcel types move. But more importantly, the tax parcel and lotcorners donâ??t break the subdivision boundary. 6. Associated FeatureClasses â?? any adjustment or movements you make to your parcels can beapplied to other simple feature classes (e.g. tax districts, utilities, zoning,etc.) that are associated to the fabric. 7. Backlots - Theparcel fabric manages line points that connect a line to another line withoutbreaking the other line (like a T junction). This helps users persist the record measurements of each parcel uniquelyand avoid the classic backlot issues (single lines with vertices thatcompromise the record measurements) youâ??d run in to using simple features and atopology. 8. Plans â?? the parcelfabric has Plans that manage a group of parcels and can specify the accuracylevel, unit of measure, how the curves are defined and other properties. A planis often used to capture a document reference number and the legal description. 9. Standards Based â?? the ArcGIS for Local Governmentsolution extends the parcel fabric data model to include domain specificattributes and best practices. Theattributes and best practices are based on the National Cadastral standard; andare encapsulated in the Local Government Information Model and Tax ParcelEditing Map. Users can easily adopt andstart working with this data model and it is the basis for all the Land Recordsmaps and apps. And as many begin toadopt this approach, organizations will be able to exchange data (county tocounty, county to state etc.) more easily. 10. Accuracy â?? Eachmeasurement has an associated accuracy. Survey control points can be improvedover time and used to run an adjustment (LSA) in order to improve overallaccuracy and identify blunders. Esriâ??s parcel editing solutioncontains more than just the parcel fabric data structure. In addition, the following is also provided: 11. Parcel Editor Toolbarâ?? the parcel editor contain tools that are specific for parcel maintenance:merge, metes & bounds, area calculation based on records measurements,construct from parent and many more. It is a ready to use and fully supportedpart of ArcGIS Desktop. Many customers are gravitating to this supported anddocumented functionality and moving away from custom tools they have to developthemselves and support in future releases of ArcGIS. Esri continues to grow and evolve this set oftools so let us know what you think. Ifyou feel something is missing submit a topic on the ideas website and weâ??ll consider it for thenext release.. 12. Parcel Workflows:Version 10.1 SP1 of ArcGIS Desktop will include a new tool called ParcelWorkflows that streamlines and improves editing efficiency. This functionalitywill only work with a parcel fabric data structure and will be optimized forthe ArcGIS for Local Government Tax Parcel Editing map. Current users will beable to upgrade their parcel fabric and easily create the editing map bydragging the fabric to the map. 13. Additional Land Records Mapsand Apps - All the maps and apps on the ArcGIS for Local Government ResourceCenter are freely available and designed to work together as a complete system.So as you begin to use the Tax Parcel Editing Map and parcel fabric datastructure, youâ??ll be able to take advantage of other maps and apps that addvalue to you organization. It could be apublic access application, a value dashboard for your assessor/treasurer, or asimple map book. Hope this helps you to make an informed decision, Amir ... View more

Hello Carol, Using labels can save you a lot time Using feature linked annotation saves you time if dimension values change and remove the annotation when a feature is deleted. Using standard non linked annotations can potentially creates conflicts and requires a lot of maintenance. You can read more about Labeling Parcel Lines With COGO Dimensions Not many counties have good COGO they can use for labeling and have no choice but using legacy annotation for the old data.  New parcels can be identified and filtered (using the Layer--> Label --> SQL) and use labels. This is sometimes referred as the "Day Forward approach". You can use the Maplex labeling engine (Maplex is part of ArcGIS Desktop 10.1) to always place the label in the middle of the line (50%).
